RivaTuner 2.0 fan speed & Overclock Guide

Found this guide. Hope it helps. DOK http://www.guru3d.com/article/article/449/

Well it is pretty obvious your MB won't support a P4 CPU. I suspect if you have the latest Bios then this is down to the OS as to how the fan is controlled. Did you do a clean install of the OS when you installed this board and CPU? If not you could have a serious driver conflict.
You can also use proggies like Speedfan to control the fans speed and monitor them. Keep in mind that most Computer fans have a minimum speed they can go as well before they simply shut off.
The temps you have are pretty good overall so if it is just noise you are concerned with then it is likely different fans or even going to water cooling is the way to go to reduce noise.

Why Overclock?
Today, overclocking is not any secret. It has become more popular and almost become an addiction to some people. The definition of Overclocking is simple: it means operating an Integrated Circuit beyond its specified clock speed.
But why overclock? Some people say to get more out for the same money. “It’s there; why not get more out of it?” However, the best business reason for overclocking is that it can make “out of date” equipments useful again. If the equipment is already out of warranty, the risk is very limited. (I personally suggest any beginners to overclock any out of date PC first just to have some first time experience.)
Know more about the Central Processing Unit (CPU)
Processor speed is based on two factors. The first is the interface between the motherboard and the front side bus (FSB). From http://en.wikipedia.org/wiki/Main_Page (Wikipedia, the free encyclopedia), FSB is the speed at which the CPU communicates with RAM (memory). Many system components - including the PCI and AGP buses usually run at speeds derived from the frontside bus' speed. In general, a faster frontside bus means higher processing speeds and a faster computer. The other factor controlling a CPU's speed is the clock multiplier. It defines the ratio of processor speed to the FSB.
The FSB on new processors ranges from 400 MHz to 800 MHz. These are not straight clock speeds but instead they are quad-clocked speeds. These processors actually transmit data four times per clock cycle, for example, 800 MHz FSB is actually four times the 200MHz clock (200 MHz x 4 = 800 MHz).
The core speed of the CPU is the product of the front side bus clock and the multiplier. A processor running at 3600MHz (i.e. 3.6 GHz) might be having 800 MHz FSB, this means there is a clock multiplier setting of 4, and thus the CPU is set to run at 4 times the MHz speed of the front side bus.
But we said earlier that they are quad-clocked speeds, so 3600 MHz actually came from 18 times 200 MHz (200 MHz x 18 = 3600 MHz).
Please note that not all processors have quad-clocked speed FSB. For example, the Intel Pentium 4 (Northwood core) has quad-clocked speed FSB. But for example, the Intel Pentium III, AMD Athlon XP and AMD Duron have dual-clocked speed FSB only.

Let’s lock the clock multiplier
Few years ago, you could overclock processors by choosing a higher multiplier. This option was eliminated in order to fight CPU remarking. Counterfeit processors have regularly appeared in the market, as the CPU speed was only defined by your setting. Nowadays, the restriction to only one multiplier is both of overclocking and counterfeit prevention.
As you can see, the only way of overclocking today is choosing a higher front side bus clock and the offer of small increments e.g. 1MHz in today's motherboards give us a great advantage in overclocking.
However, some CPUs nowadays are still unlocked, for example, the AMD Athlon MP and AMD Athlon64 families. And some motherboard companies offer the chance to unlock the Pentium 4 (Socket 775 CPUs only) overclocking potential by using special bios, for more please read:
http://www20.tomshardware.com/motherboard/20040916/index.html
Look at your motherboard
Before you overclock anything, have a look if your motherboard can overclock CPU. Look at the CPU installation section in the motherboard manual. Normally you will find either BIOS setup options or jumpers on the motherboard that allow you to adjust the FSB, CPU voltage, PCI/AGP ratio etc.
If you have a computer that came from a major manufacturer like HP, it is likely that your motherboard does not provide any overclocking function although it is very rare nowadays.
You need more Power!
This is also the time to check the power supply in your computer. Like a car, speed requires power, and unstable power inevitably leads to unstable processors, so I would recommend the power supply has to be at least 350 Watts. You can find six power supply guides in this forum below:

Both Intel and AMD processors are power hungry, consuming 40 to 100 watts (e.g. the new Prescott) of power. Also, your graphics card may take another 55 watts of power. Now you are consuming more than 100 watts of power for merely two components in your system.
You can also voltmod your Power Supply Unit, for more please read:

Using higher voltages
Today, almost each processor can be run faster than the speed it was labeled for. This applies even more if you raise the core voltage a little bit. This is just like a car running at higher speed requires more power. But this is one of the “riskiest” aspects of overclocking - by using too much power you could burn your CPU. You should always raise the voltage step by step and never go higher than 15% beyond the specification. This way it is quite easy to get a faster system without risking the processor. Apart from raising the voltage of the CPU, similarly you can raise the voltage of memory as well. One problem is of course the increasing chip temperature, so cooling is very important. We will cover that later.
Memory Speed
Memory speed is often tied to the FSB. For example, a Double Data Rate (DDR) 400 memory has frequency 200MHz and the module rating is PC3200. Half the performance increase you may see from overclocking a CPU comes from increasing the speed at which the processor can talk to the memory.
When you buy memory, you may see it has label 2-3-3-7-1T. And you may also hear people saying my memory is a 2-3-3-7 one. But what does it mean? The answer is:
CAS Latency = 2 clock cycles
tRCD = RAS to CAS delay = 3 clock cycles
tRP = RAS Precharge = 3 clock cycles
tRAS = Active to Precharge = 7 clock cycles
Command Rate = 1 clock cycle
Different motherboards may call the above differently and not all of them will appear in the BIOS. You may need to check with your motherboard’s support team and the motherboard manual. If you have any option above in your BIOS, you can also start to adjust them. Obviously, the smaller the number the faster the memory will be.

Video Card
To overclock video card, we need a third party utility to overclock the card. Although increasing numbers of manufacturers include utilities to allow customers to overclock their cards in their drivers or through an extra application, most of them do not provide this facility. Simply because overclocking stresses the system and voids manufacturer warranties. Third party utilities tend to be universal that they work on different cards irrespective of manufacturers.

Get the temperature down
Cooling is probably the most important aspect of overclocking. Overclocking causes circuits to cycle faster, generating more heat. If the CPU is not cooled properly, your CPU will not run reliably and there is a very good chance that you will permanently damage your CPU.
The heat sink and fan unit that Intel and AMD ship with its CPU are fairy good. However, for maximum stability, we need to get something better than that. For example, for CPU fans, we have Vantec Tornado, Thermaltake volcano 7+, CoolerMaster Aero 4 and Zalman CNPS7000A-AlCu etc.
Be sure that the cooling solution you choose is specifically designed for your processor. Improperly mounting a heat sink, using the wrong model can damage your processor.
Also, the airflow in the case is very important. If heat cannot escape the case, the CPU is still at risk. Thus, more case fans are needed apart from the power supply's exhaust fan. Tidying up the cables inside the case can help too. In addition, clearing the dust in the case by using canned compressed air can enhance the airflow but never use vacuum cleaner as it may generate electrostatic and harm the IC components.

Overclocking Process
Essentially, overclocking processors consists of increasing the FSB in the BIOS, booting the computer, and then testing for stability. You repeat the process until you identify the maximum stable speed.
In case your board offer 1 MHz-increments (which most of your boards do), you have the chance to find out the maximum clock speed by slowly closing in on the final limit MHz for MHz. Of course this cannot be done in an hour, but you will have to spend one or two days just playing with different clock speed settings. In the end you should have your CPU running at the highest possible core speed. The Most important thing to remember is that you must go Slowly!
Also, you can overclock the processor by using software although it may not be as effective as overclocking using the motherboard BIOS. Such software includes:
1. ClockGen

Bear in mind that if the processor is capable of a 20-percent or more speed increase say, it is unlikely that your video card or memory can have the same amount of increase. And the one thing that you must remember to do if you overclock the FSB is to Set (i.e. Lock) your AGP/PCI Buses, to as close to their Default Frequencies as Possible (to PCI bus at 33 MHz and the AGP port at 66 MHz for example), or you will most definitely experience problems across the whole board e.g. your graphics card, onboard sound and IDE channels may start giving you data and other errors.
Test for Stability and Benchmarking
The purpose of testing is to apply a heavy workload to every aspect of your system to ensure that there are no hidden problems and stability issue. You can do testing by using special testing suites, software and games. The aim of benchmarking is to measure the performance of your system. In overclocking, benchmarking can tell you how far the system’s performance has increased when you adjust certain settings.

I tried to overclock my p4. 2,66ghz to 3.18ghz.
l increased the cpu fsb only since the multiplier is fixed at 20x.
l tried to change it but couldn´t.
l then increased my cpu voltage from 1.525v to 1.732v.
At 3.2ghz, the computer was on and restarts automatically, so l turned it to 3.18ghz.
does it mean the cpu will not overclock further or l need a new cooler?
I did not overclock anything except the fsb.
any help?
I have a 2.6C Northwood pentium 4 on an MSI 875P Neo2-FISR mobo. On air I'm able to get it to about 3.14Ghz stable. I don't believe it's a good idea to go past 1.6 for the voltage, from what I've read, voltage doesn't help too much with the northwoods.
I can overclock mine higher without any significant changes in temperatures, but the overclocks aren't stable and the system freezes up from time to time. I'm using Kingston HyperX PC4000 DDR, which can run at up to 500mhz, so I can do a 1:1 ratio on the overclock. I'm using a modular 500-watt power supply, Arctic Silver 5 and a huge honking Swiftech heatsink with an 80mm fan.

Neo4 Overclocking Guide

This guide is intended to help those people who have K8N Neo4 (nforce 4 based) boards. It will provide some general background information, but a lot of things will be specific to this particular series of motherboards, and in general it is assumed that the user is at least moderately familiar with the basic concepts of computer hardware and the concepts and risks associated with overclocking. As usual, I am in no way responsible for any losses/damages resulting in whole or in part from the use or misuse of this information, or in short, "overclock at your own risk". It should also be noted that I have the Neo4 Platinum, so things might be slightly different for those of you with the SLI or other variants of this board, though I would strongly suspect that most of the overclocking features will be pretty much the same. Anyways:
The Basics:
Okay, for those of you who are new to the overclocking crowd, here is a quick overview of some of the essential bits of knowledge. A very complete and thorough introduction and general overclocking guide is also available at https://forum-en.msi.com/index.php?topic=40413.0 for those of you who need extra help.
CPU Speed - If you don't know what this is, then I wonder what you were hoping to attain by accessing an article about "overclocking". The main aim of overclocking is to increase the CPU speed beyond what it is originally specified to run at. The CPU speed is equivalent to the product of your FSB speed and the CPU multiplier.
FSB - FSB is short for "frontside bus". Historically the FSB essentially controls the speed at which the CPU is able to communicate with the rest of the system, and this is pretty much still true for the Athlon64, although the impact of higher FSB speeds is somewhat diminished, as we will see later. On the Neo4 (and most any other board) the FSB and various multipliers/dividers are responsible for determining the core CPU speed, the memory speed, and the HTT speed. You PCI-E bus is locked, so raising the FSB will not cause your video card and other devices to become unstable. Additionally, there is no need to worry about an overclocked FSB screwing up the built-in SATA/IDE controller (the nforce one at least, I haven't tested the SiL, although it should be fine as well).
HTT - HTT (or sometimes just HT) is short for "HyperTransport Technology". Not to be confused with the HyperThreading feature on Intel's P4 processors, this is the communication link between an Athlon64 processor and the PCI-E bus, as well as everything that hangs off this bus, including the SATA/IDE controllers and so on. Basically, everything except for the RAM talks to the CPU via the HTT bus. The speed of the HTT bus is determined by taking the product of the FSB speed and the HyperTransport multiplier, and it provides an extremely large amount of potential throughput, so much so that once its speed is above about 800 MHz, there's very little to be gained by pushing the HTT speed higher.
Memory Clock - The memory clock refers to the speed at which the RAM modules are operated. The memory clock is determined by taking the FSB and applying a ratio to it. Generally speaking, a higher memory clock is better, although there are tradeoffs in terms of latency if memory timings (CAS latency, etc.) have to be loosened in order to get the memory clock higher, or if a ratio other than 1:1 is used (which will be necessary for high overclocks unless the RAM you are using is of extremely high quality).
PCI-E - The PCI-Express bus. This provides connectivity for your graphics card(s) and other add-in cards. The default PCI-E speed is 100 MHz, and this is locked on the Neo4 so that increasing the FSB does not increase the PCI-E speed. You may manually increase the PCI-E speed if you wish, although this is not at all recommended.
vcore - This is an abbreviated way of referring to the voltage that is applied to the CPU. Generally speaking, a higher vcore will provide stability at higher clock speeds, the tradeoff being additional heat, which may or may not require a more robust cooling solution, depending on how high the vcore is being pushed, the quality of your thermal interface compound, and the thermal characteristics of your individual CPU (some just overclock better than others). For the 90 nm Athlon64, the default vcore is 1.40V. The default is slightly higher for the 130 nm variants.
vmem - Similar to "vcore", this is a shorthand way of referring to the voltage that is currently being applied to the RAM modules. Again, an elevated vmem will generally give you improved stability at higher memory clock speeds. Memory specifications vary from manufacturer to manufacturer in terms of what voltages are supported (for instance, my RAM supports from 2.55V to 2.95V), though the default voltage is usually 2.65V. Vmem, vdimm, and vram all refer to the same thing.
Purchasing:
For anyone who happens to stumble across this guide while in the process of looking for some new hardware, I thought I'd list some of the things that are important considerations when you are buying a system with the intent of overclocking it.
The CPU - For most people, the main point behind their desire to overclock is that they want to be able to get a cheap CPU, and then run it at the same speed (or faster than) of a CPU that costs much more (possibly one for which the price premium has not come down on yet). When choosing which CPU to purchase, there are a few aspects that are especially relevant to overclocking (I'm going to assume that you've already decided to use an AMD CPU, due to the reduced overclockability, thermal problems, and generally poorer performance in most areas despite having higher raw clock speeds that all of Intel's current P4 models offer). Arguably the most important feature (when looking at the current Athlon64's anyways, which are very good CPU's and which you have to use if you want the Neo4) is the manufacturing process used. This denotes the size of the smallest individual feature on the chip (smaller is better). Your two choices right now are 90 nm and 130 nm. The 90 nm carries a fairly small price premium (about $10 for the 3000+/3200+ models), but is *much* more overclockable due to the fact that it operates at a lower voltage (and thus generates less heat), and also uses a more "mature" revision than the 130 nm parts. It is *strongly* recommended that you make sure to get a 90 nm CPU if you are in the market for a new socket 939 Athlon64. The next thing to consider is the default CPU multiplier. This is the one reason why it might be preferable to get a 3200+ over a 3000+ chip (generally speaking, all the 90 nm Athlon64's have about the same upper limit on their overclocked core speeds, until you hit the still very expensive 3800+ and FX variants, so it doesn't make sense to buy a more expensive CPU when you're not getting any extra overclockability out of it). The multipliers on the Athlon64 CPU's are "half-locked", meaning that you can run at the default multiplier (9x for the 3000+, 10x for the 3200+), or any multiplier that is smaller than the default, but you cannot select a multiplier that is higher than your default multiplier. Thus, getting the 3200+ over the 3000+ gives you two extra multipliers (10x and 9.5x) and, all things being equal, will let you achieve a higher clock speed before you are forced to run your RAM asynchronously and pay the latency penalty for doing so, although your max clock speed will likely be about the same as it would if you had gotten the 3000+ instead (so if you have cheap RAM that's not giong to overclock well at all, there's very little reason to go with the 3200+ unless a RAM upgrade is planned in the near future). So, for overclocking purposes my recommendation is a 90 nm Socket 939 Athlon64 3000+, or if you have high performance memory and want to get the most out of it, the 3200+. Both chips are competitively priced and should overclock at least to 2.4 GHz, if not higher, on stock cooling (spend the extra $10 for the non-OEM variant and get the HSF that comes with the chip, it works as well as many more expensive third-party air-based systems and is well worth the extra $10), and of course both offer the attractive feature-set of a socket 939 Athlon64 (dual integrated memory controllers, 64-bit support, dual-core processors on the future upgrade path, etc.).
The Motherboard - The motherboard is an important part of overclocking as well. There's not much point in getting a highly overclockable CPU and then pairing it with a mainboard that was not designed with overclocking in mind, and this is one area where the Neo4 really shines...it has superb overclocking support. Probably the most important feature to have if you indend to overclock your CPU by 20%+ (which should be easily attainable on either of the recommended CPU's above) is that the board have locks that prevent the overclocked FSB from overclocking parts of the system that can't handle the extra speed (like the PCI/PCI-E bus, for example), and long story short, the Neo4 has these (unlike the Via-based K8T Neo, which had no locks and which limited SATA users to overclocks of no more than about 225 MHz because any high than that and the SATA controllers would start to become unstable and kill your HDD data...working locks are a very good and important thing if you are overclocking). The next important feature is to choose a board whose BIOS lets you control the options that are important for overclocking. Again, the Neo4 does excellent here, letting you pick your memory divider, memory timings (and some very obscure ones at that), CPU multiplier, FSB speed, HTT multiplier, CPU voltage, chipset voltage, RAM voltage, and so on without complaint. The MB also has a handly little button on it that will clear the CMOS with a single press (no more screwing around with those annoying jumpers) in case you screw up and the system won't POST. The board also has some extra cooling hardware installed in the form of a passive heatsink near the rear I/O panel, but mostly it's the presence of functional locks and the wide range over overclocking related BIOS features that make it attractive from an overclocking perspective. Aside from this, it has a very nice feature set in general, including 8 SATA ports and 2 IDE channels (for a total of up to 12 drives), two gigabit ethernet adapters, firewire, 7.1 channel audio, and the additional selling point that nvidia's unified drivers tend to be much easier to install than most companies' drivers.
Cooling:
Okay, one last thing to consider before the overclocking starts. Cooling is important in general and especially if you are going to be overclocking. While a 90 nm Athlon64 performs rather admirably from a thermal perspective even when only stock cooling components are used, some simple modifications can drop your idle/load temps by 5+ degrees, which can give you a bit more overclocking headroom and which in any event will make your CPU happier.
Case Fans - The first thing you want to do is make sure your case is adequately ventilated...in general a single 120 mm exhaust fan will do the job just fine. If your case does not support fans this large, use at least two 80 mm fans, either both as exhaust, or one as exhaust and one as intake (if they perform differently, use the more powerful one as the exhaust fan to avoid overpressuring your case). If noise is a concern, the Vantec Stealth (http://www.newegg.com/app/ViewProductDesc.asp?description=11-999-614&depa=1) series of case fans are affordable, come in a variety of sizes, perform quite well, and do not make much noise at all (though you might want to consider doubling up on the 120 mm's just to be on the safe side). This can lower your CPU temp by about 2 to 5 degrees over a poorly ventilated case configuration using the same CPU fan.
CPU Fan - As I mentioned earlier, the default CPU fan that comes packaged with the retail Athlon64 chips is perfectly acceptable for overclocking use in my opinion. The only complaint I have is that the thermal compound that comes preapplied to the HSF is fairly cheap and does not perform that well. I *very strongly* recommend replacing it with Arctic Silver (http://www.arcticsilver.com/as5.htm) before ever installing it on your CPU. To remove the default thermal pad, you can use a razor blade to get most of it off, and then hot soapy water (or denatured alcohol I've heard) to remove any remaining reside. Be sure that the HSF is free of any cleaning residue and also of any moisture before going to install it on the CPU, and then just apply the Arctic Silver and then complete the HSF installation, and you're good to go. Arctic Silver is relatively cheap (the tube you'll get will do several CPU's, and it doesn't go bad), and by replacing the thermal pad that comes on the stock HSF with it, you should be able to reduce your idle/load times by at least 5 degrees, and with this plus the added reduction you get from having a well ventilated case, you should have enough headroom to pull off some pretty aggressive overclocks.
Overclocking:
Finally, on to the good (and Neo4 specific) stuff. Hopefully at this point you have a freshly built Neo4 based system with an Athlon64 CPU that provides a large headroom for overclocking.
Initial Setup - Okay, the first thing you're going to want to do once the system is built and powered on for the first time is enter the BIOS and configure everything to run at its *default* settings. It's not quite time to overclock yet. First, you want to install Windows, patch it to SP2 if necessary, and then install some benchmarking, stress testing, and monitoring software. SiSoft Sandra is a good benchmark suite, as are FutureMark's PCMark and 3dMark lines of software. For stress testing you can use SuperPi and Prime95 (and Memtest86 if you don't mind the tedium of having to reboot in order to use it, which I do so I don't bother with it). For monitoring you can use SpeedFan or Motherboard Monitor 5. At the very least you should install one application from each category, and configure your monitoring software to launch when Windows loads. One you have all this configured and working right, it's time to start overclocking (don't install too much else, in case of the worst case scenario in which an instability causes your HDD to become corrupted, requiring a reinstall of Windows and all the software, which is admittedly very unlikely, but unfortunately possible if you're unlucky enough). For comparison purposes you may want to run some benchmarks and record the results before you start. Additionally, you may want to install something like ClockGen, which will let you tweak your FSB/CPU coltage on the fly and which can make it easier to zero in on a stable configuration without having to reboot every time an instability is found.
BIOS Layout - Just to save some time, I'll describe where BIOS options that we'll be using are all in one place, so that when I reference something you can just look up here and figure out how to find the appropriate setting in the BIOS. Basically, there are two pages that we're interested in for overclocking (note that the Neo4 manual is actually extremely well done, and describes pretty much all of the BIOS options, so you can use it as well). The first is the "Advanced Chipset Features" page. Going "Advanced Chipset Features" -> "DRAM Configuration" brings up pretty much all of your memory related options (divider, timings, etc.), *except* for the RAM voltage. The RAM voltage option is on the "Cell Menu" page, which happens to also contain all the other settings we are interested in, including FSB speed, HTT multiplier, CPU multiplier, vcore, vmem, chipset voltage, etc.. Basically, if it's not memory related, it's on the "Cell Menu" page.
HTT Speed - As mentioned earlier, your HTT speed pretty much has no performance impact on the system once it gets to 800+ MHz, so the very first thing you can do is select the 4x HTT multiplier in the BIOS. Note that as the HTT speed gets above about 1100 MHz, it will probably start to make the system unstable. Therefore, you should keep track of the product of your FSB setting and your HTT multiplier, and whenever it gets to be above 1100, decrement the HTT multiplier to the next lowest setting. at a 4x multiplier, you should be good up to about 275 MHz on your FSB. Because the HTT's impact on performance is negligible, you do not need to worry about trying to maximize its value during overclocking.
CPU speed - Onve you've reduced your HTT multiplier, it's time to find your max stable core speed. To do this first go to the memory page and select a memclock index of 100 MHz. This will run your RAM it half the FSB speed, and the reason for doing this is to ensure that as we raise the FSB, any instability the occurs is a result of the overclocked CPU and not a result of overclocked RAM, so that we can be sure that we have indeed found the maximum stable CPU speed when we are done. Leave your other RAM settings at their defaults, we'll come back and tweak these later. Now go to the CPU page and select "Manual" for the "High Performance Mode" option if necessary to enable editing of the settings. You should disable Dynamic Overclocking (since you are doing this manually) and I recommend disabling Cool'n'Quiet, though you don't have to if you really don't want to. Disable all the "... Spectrum" settings (what these do is kind of complicated, but the manual plainly states that they should be disabled if you are overclocking, so heed its advice). Also disable "Aggressive Timing", as this will decrease your RAM overclockability substantially without providing any real benefit (and may make it unstable even at its rated settings). Now, what you want to do is, leaving the other CPU settings (i.e. vcore and multiplier) the same, start raising your FSB Frequency in 10 to 12 MHz increments, depending on your multiplier (basically you want to raise it about 100 MHz at a time). Some people feel this is a fairly large jump to do at a time, but I've found that the Athlon64 handles it just fine. If you get up above about 2.4 GHz, then you might want to only go by half of this at a time though. Remember to decrement your HTT multiplier as necessary. Basically, every time you raise the FSB, test for stability by letting the system try to boot to Windows. If it is successful, return to BIOS and raise the core speed some more. Once the system fails to boot, you have two options, either raise the CPU voltage (use the "CPU VID" setting in the BIOS to adjust the voltage directly, or the "CPU Voltage" setting to specify how much over the specified amount of voltage to apply...personally I prefer the "CPU VID" route, but it's really a matter of personal preference, and yes, both can be manipulated in unison...one thing I've noticed here is that the "CPU Voltage" settings seem to allow for less variance in the final vcore setting, keeping it very close to the specified voltage at all times, whereas increasing via the "CPU VID" option lets the voltage decrease a bit from the specified value when the system is not under load) and try again (and keep repeating until you have given the CPU as much voltage as you are comfortable with and the system can no longer be made stable), or return to you last stable setting and let it boot. Once you have done this, use your benchmarking and stress testing software to make sure you really are stable at your settings. If the system crashes or the test reports errors, you will either need to raise the voltage a little, or lower the FSB a little (this is where ClockGen can be a big timesaver). While some people swear by Prime95, my opinion is that if you can get through the largest SuperPi test without any errors, your overclock is stable. Monitor your temps while you do this. If you notice that the CPU temperature is getting above 60 degrees, you are running a bit too hot. Generally speaking, about 55 should be considered the threshold of safety here. If you're running hot, you can either decrease the voltage and FSB settings, or get a better cooling solution. Once you have determined that your setting is stable and not overheating your CPU, record your core speed (not your FSB speed, the total CPU speed) and voltage settings for later. You should probably be shooting for a target clock speed of around 2.4 GHz, or more if you have good cooling, or if you are interested in doing a "safe" overclock, just shoot for as high as you can get without raising the voltage.
Memory Speed - Now that you know your CPU's limits, it's time to work on the RAM. First restore your FSB to 200 MHz and your CPU voltage to its default, and specify a CPU multiplier of 6x to make sure that the CPU will not be stressed as your raise the FSB. Go to your RAM page, and manually specify whatever timings are appropriate to your RAM modules. Also be sure to set "1T/2T Memory Timing" to 1T (set the "... Mode" setting to Manual to make the RAM settings editable). Leave the rest of the settings alone, except for the "Memclock Index Value". Here, you have a choice to make. If you have high quality RAM, or your target CPU speed is not too high (like < 2.3 GHz), you can try to run your RAM synchronously, which will give you somewhat better latency. If this is the case, select an index value of 200 MHz (note that on the Neo4, when you select a memclock index what you are really specifying in the ratio at which the RAM operates relative to the FSB...the memclock index option is basically just obscuring this setting. To calculate your ratio, divide whatever the index value is by 200, so an index of 200 MHz is a 1:1 ratio, an index of 150 MHz is a 3:4 ratio, and so on). If your RAM is not of very high quality (for example, it's only rated as PC3200), or your target CPU speed is high, you will likely need to run the RAM asynchronously, so select the next highest index value of 180 MHz. This will let you get slightly higher RAM clock speeds, at the cost of a little bit of added latency (the performance hit isn't much...you'll be much faster running asynch at 2.4 GHz than synch at 2.2 GHz). Now you do the same thing that you did with the CPU, gradually increasing the FSB (you might want to use smaller increments this time though) until the system will no longer boot (remember again to decrease the HTT multiplier if necessary), and then returning to your last stable setting (or increasing the voltage and repeating) and booting to Windows and running stability tests. You do not need to monitor your temps while doing the RAM tests (unless you want to). Generally I find that Sandra's "Cache and Memory..." benchmark works well for detecting memory instability, and you can also use SuperPi, Prime95, or Memtest86 as well. Once you have tested stable, record your memory clock speed (use the formula: memory speed = FSB speed * memclock index value / 200) and voltage and reboot to the BIOS settings menu. Note that while you may be able to attain a higher memory clock speed by selecting a higher CAS latency, it is not generally advisible to do so, as from what I've seen, although memory bandwidth remains about the same as CAS increases (as far as Sandra is concerned anyways), the lower latency provided by CAS2 improves the system score by 5% in PCMark 04, and given that RAM performance scales pretty much linearly relative to the clock speed, unless running at CL2.5 lets you get *at least* 10 to 15 MHz higher than at CL2, it is not worth it overall.
Run the Numbers - Believe it or not the performance of the Neo4 system is dictacted pretty much entirely by the core and memory clock speeds (given identical memory timing settings). The only other real factor is whether the RAM is run synchronously or not, which you just decided in the above step, so all that's left to do now is find the combination of memclock index, FSB, and CPU multiplier that allow you to get as clost to both your target core and memory speeds as possible. If you are running synchronously, your task is simple, just keep your memclock index of 200 MHz, specify your target FSB speed, and your default CPU multiplier (unless your RAM is so good that the CPU is not stable at the default multiplier and the RAM's top FSB speed, in which case drop the multiplier accordingly). If running the RAM asynchronously your task is a bit more difficult (having a calculator for this part will help), basically you have to go through the list of memory dividers (memclock indexes), and for each one calculate the ratio of memclock index / 200, and then divide your target memory clock speed by that ratio to get the FSB needed to attain your target memory speed (for example, if the target is 230 MHz, for a memclock index of 150 we get a ratio of 0.75, and 230 / 0.75 = 307 MHz, so running the RAM at 230 MHz with an index of 150 MHz requires a FSB setting of 307 MHz...pretty good if your target clockspeed is 2.45 GHz, as selecting an 8x multiplier will pretty much hit this exactly), and then go through the available *whole* CPU multipliers (I've heard that the half-multipliers should be avoided, as they cause the memory to get clocked incorrectly) and see if any multiplier times the FSB you calculated hits (or comes reasonably close to hitting) your target CPU speed. Go through all of them until you get an exact (or very close) match, and pick whichever one ends up matching most closely. Note that there is no benefit in this case to a higher FSB speed configuration over a lower FSB speed configuration, provided that both produce the same core and memory clock values, so you should not favor configurations with needlessly high FSB settings unless they produce a better fit than the others. Apply whichever settings are closest, and then apply the appropriate CPU and memory voltage settings that you got from the previous steps. Also apply whichever HTT multiplier will put you closest to 1000 MHz without going over 1100 MHz. After this, your system should be ready to boot, overclocked and stable. Be sure to do additional benchmarking and stress testing to make sure that you really are stable (if you saved your scores at the beginning, compare them to your scores now and marvel at the improvement...and post the results for people to see), and be sure to monitor your temps for a bit to make sure your cooling is working adequately.
Post Overclock Overclocking:
There's not a whole lot to do now, but if you want to try to tweak your memory timings to get a little bit of extra performance, now is the time to do it...just remember to record your stable overclock settings somewhere (*not* on the computer) in case the tweaking forces a CMOS reset and you lose all your settings, and enjoy. Also you can overclock whatever video card you have, a process that's much easier and faster than overclocking your CPU/RAM/FSB.
In Closing:
I hope someone out there finds this useful, given how long it took to write up. Maybe I'll get lucky and this will end up as a sticky...we'll see. And just to start things off, here are my benchmark scores, at stock and at the overclock described in my sig:
Stock:
3dMark05 = 3141
PCMark04 = 3589
Overclocked:
3dMark05 = 3704
PCMark = 4805

Just started ocing the system, I'm new at this so these are where my system stands and the results

K9n Platinum fan speed control

Hi!
I have the following configuration:
-Motherboard: MSI K9N Platinum v1.1
-Bios: AMI v1.3
-CPU: AMD Athlon 64 X2 Dual Core)
-CPU cooler: Artic Cooling Freezer 64 Pro
-Memory: Kingmax 2*1 GB
-Video card: MSI NX7600 GT
-Power Supply: Antec NeoHE430 430W
-Hard Drive: Samsung 250 GB SP2504C
-Operating system: Win XP Pro SP2
I would like to control the speed of the CPU fan automatically, according to the temperature.
I tried
-the Dual CoreCenter utility from MSI, but it allows me only check the speed manually (If I did not miss anything)
-control from BIOS HW Monitor setting SmartFan but it does not work at all. ( Iam not sure but this can be because my cooler, it has 3 pin connector, and th MB user guide tells it works only if I use 4 pin connector. Can you confirm this?)
-Speedfan 4.31, it seemed working, but the system become instabile. I check the programmers site, and this MB did not supported.
Do you have any suggesions, experience about controlling the CPUfan?
Thank you in advance!
T.

Thank you for the answers.
Unfortunately the smartfan feature is not working in my case.( set to 3-pin in BIOS) I asked the MSI Technical Support and they said:
As this motherboard includes 4 pins connector for cpu fan, the 4th pin is used to controlled cpu fan speed, if you use 3 pins fan, fan speed will not be changed automatically and smart fan will not function.
I feel a small contradiction here
Do you have other ideas other than smartfan and speedfan?

CPU heats up on file copy/backup and fan speed does not increase

Hi Friends,
I have been having issues with fan in my Dell Studio 1555. It has an ATI Radeon card and I had installed the proprietary catalyst driver as the open source driver is too noisy.
Recently, I noticed that on accessing my hard disk and copy files or running backup (luckybackup), the temperature shoots up from around 60 deg C (just using chrome) to 100 deg C when it would shut down itself. However, it seems like the fan speed does not increase with the increase in temperature to help it cool down.
I tried to get the fan speed details with "lm-sensors" but it would not show the fan speed. Here is the output of sensors:
[user@domain]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +60.0°C (crit = +100.0°C)
temp2: +59.0°C (crit = +100.0°C)
temp3: +66.0°C (crit = +100.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +58.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +58.0°C (high = +105.0°C, crit = +105.0°C)
Following the Arch wiki, I added acpi_enforce_resources=lax to kernel parameters but it did not help as well.
Here is the main problem:
1. CPU temperature shoots on accessing hard drive but fan speed does not increase - Any guide/direction to investigate would be really helpful.
2. Sensors does not show the fan speed. Read about i8kutils, but couldn't figure out how to get it working with systemd. Any indicators here?

MSI P6NGM-L system temperature and processor fan speed

Hi folks,
I've got a MSI P6NGM-L board that is reaching a system temperature of 46ºC-47ºC at everyday load (not playing games or doing heavy work... just browsing, email, text editor, etc). My case has got a frontal and rear 120mm (exaustor) fan, and my processor (Core 2 Duo E7200), an Akasa AK-965BL cooler. My graphics board is a XFX Geforce 9800GT with Zalman FC-ZV9 cooler. Overall temperature is just fine, except for the system temperature, that is 32ºC when the system is turned on and is cold, and reaches about 47ºC after some time and using. I disabled the onboard NVIDIA on BIOS, but that didn't make any difference. Is that temperature OK for my configuration, or somehow high?
I thought about taking off the northbridge heatsink and applying Arctic Silver 5 in it, but I don't know if that would make any difference, and it would give me a big job, because I would have to take the board off... so I don't know if it's worth.
Another question, is P6NGM-L board PWM compatible? I tried using speedfan to control the processor's temperature but it says it's at 100%, and I know the cooler is in silent operation. If so, what software should I use to control the processor fan?
Thanks for any help

I don't have a way to measure my room's temperature, but it's quite hot... something like 26ºC.
I thought that with all the cooling I've got inside my case the system temp would get lower, but it is still the same under normal load, even since my case had only one exaustor and stock coolers.
What about the processor's fan speed? Can I really change it by software? I plan to do some overclocking, so I would like to do tests with the processor cooler in full speed... I've googled all the way around, but couldn't find substancial information about P6NGM-L support for that.
Thanks

Geforce 9800GT always at 100% fan speed, no adjustment possible

Here's what I've discovered so far:
Changing the fan speed (even with superuser privileges) in nvidia-settings doesn't work.
"nvclock -f -F 50" outputs: Error: adjustment of the fanspeed isn't supported on your type of videocard!
nvidia-settings reveals the GPU is at 65% speed all the time, even when the fan is supposedly on "auto" and cold. I can change the fan manually above 65% (but only in nvidia-settings); however, the fan does not make any audible changes in noise level.
nvclock reports GPU temp is -398C. nvidia-settings reveals what I believe to be the correct temperature of 37-38C (it does fluctuate)
Strange things that I don't think are directly related to this problem
2D and 3D clocks appear to be the same stock under nvidia-settings. Overclocking appears to work, but changes both at the same time.

MSI Afterburner Fan speed?

i have a MSI Radeon HD 5970 g.c. and i recently adjusted fan speed to cool off to about 35 degrees C when pc starts.
to do this i raised fan speed to about 60%.
normally, the fan comes on and while progressively cooling my g.c. it cycles down to a lower fan speed.
just recently though, the fan has stopped cycling down after startup or during gameplay that causes lots of heat, cycling up to account for the heat.
i have MSI afterburner v2.0.0 with latest graphics drivers and what not(im pretty sure, as of feb. 4,2011)
is this a common problem or is there something simple i can do to fix?

Try downloading Afterburner 2.1.0 Beta 7 here and see if that changes anything.
The one you have is older and known to have issues.
Edit:
Here's a quote with from the changes they made:
Quote
Fan control settings are now being forcibly reapplied after changing the clocks via unofficial overclocking path to bypass bug in AMD driver causin the fan control settings to be reset to defaults after programming PowerPlay table
So that might be the problem you have.
Good luck

Yeah, I know that all that info probably isn't that necessary.
Problem: I have a Thermaltake cl-p0533 for my core i7 920. My fan runs 6000+ RPM all the time. I've tried using the overclock center, greenpower center, and the BIOS smart fan thing. In BIOS, I tried setting it to 25% idle and 50c target temp range. No dice. I've tried using speedfan and all that I got was the speed knocked down about 300-500rpm for a bit. My CPU idles at about 33c (according to speedfan and OC center). The CPU fan speed is supposed to be able to be controlled. The noise is really annoying. Any help would be most appreciated.

Core i7 290
First, I meant 920 (I must be dyslexic or something)
Yes, the CPU fan is connected to the CPU fan power connector (according to the mobo manual). I've set SpeedFan for the same as I had my BIOS settings. I've since changed them to lower temps. I've tried SpeedFan with and without using the SmartFan feature in the BIOS enabled. My Two case fans are super quiet, so I don't use any regulation for them. So my SpeedFan settings look like this:
Speed 1 - minimum value = 25% maximum value = 100% auto variated
Temp 1 - Desired = 42c warning = 50c
Cores 0-7 = same as Temps 1 settings
I've also disabled the other temperatures for monitoring and fan control
As for the number of wires for the cooler fan, there are 4 going to the mobo.
I don't really know much about add-on fan controller parts. If that's the route I end up needing to go, any recommendations?

MSI Dual CoreCenter - fan speed warning

Hi MSI community!
I have a MSI K9n Neo V2 and I have installed MSI Dual CoreCenter on my PC. Now the problem is that MSI DUal CoreCenter keeps warning me about low CPU fan speed (~900 rpm). I noticed that the limit is 1000 rpm. The thing is my CPU doesn't run hot, 30-40 °C (90-100 °F), so the warning is quite irritating.
Is there a way to turn off warning, or lower the warning fan speed limit (regedit?) so I still can use this program?
Kind regards
Mike

Thank you, mate! Will do so!
you're welcome
I also agree with Hans, you don't really need it

Are you overclocking the system? If not, don't use anything. You don't need a monitoring program. The bios does the work for you. (Meaning: the system will shut down when overheating. Meaning as well: the system will regulate fan speed).

560GTX TI HAWK fan speed?

So I just got a new 560GTX TI HAWK (Bios 70.24.11.00.00) not overclocked, and the bios switch on performance.
I was looking around in Afterburner and I noticed that when the fan speed is at 85% it runs at the full 4500rpm same as if it was at %100, so is the max the fans can go up to 85% or is there something wrong with my card?

I just checked mine and about the same, 4560 RPM and no difference between 85-100%. It appears then that max fan speed RPM is when it hits 85%.

N260GTX OC fan speed controls....

I recently finished off a build using this video card...newegg FTW! lol email offer was 185$ free shipping...SOLD!!!!!
I personally like to be able to control my parts...but I cant find any options to adjust fan speed manually....and Ntune shows it running at 26%[in motherboard adjustments]....I have never trusted auto and Id like to set it myself to 75-80% and go higher as needed....yes I push my gear hard and often and need it to stay cool...
Ntune wont do it and this is the first time Ive had an issue with NOT being able to adjust a fan using Ntune[I use it for fans and specs]....
I know it CAN be adjusted....but how?

Have you tried with Rivatuner?

NB Fan speed???

Would someone kindly explain
what this NB fan speed and NB
temperature!?!
Thanks :D

At the end of the day, most of the temps measured are not ABSOLUTE but rather relative estimates - some (like CPU and Sys) are just closer to reality than others.
Unfortunately for most of the Neo/Neo2 boards, MSI did a lousy job on the NB temp plus NBFAN speed - plus they decided not to monitor SFAN when the electronics needed was already onboard ;(
As observed, NB temp tends to jump 3-4 degC when you power a fan via NBFAN connector (my NB temp jumps down to 51 when the NB PWM speed is at 0%) so I have 3 suggested options:
1. Take off the lightshow fan, set aside (in case of RMA) and let the heatsink do its job alone (it does work pretty well alone) - this is the best option if you don't major overclock and have adequate casing ventilation (an intake and an exhaust), or just abhor disco
2. Use SpeedFan and increase the desired and warning thresholds - mine is set at 54 & 60 to avoid the flame icon
3. Move the lightshow from NBFAN to SFAN and use the NBFAN monitoring for controlling or monitoring other case/PSU fans

Turbo2/PC Alert III/ Adjustable Low Fan Speeds?

Anybody getting low RPM adjustable fans to register in PC Alert III?
I have adjusted the fan speed alerts on CPU and chassis to min, and still can't get proper fan RPM reading. Am guessing fans are about 1/2 speed (given the amount of adjustment I made), or about 1500 RPM. Now getting red 5 digit fan speeds and case temp jumping around.
Am not asking so I can stare at fan speeds, just to see changes in any adjustments I might choose.
Still loving the low dba of my 2 Enermax fans!

Just got a new case and some gadgets...My Thunderbird 1400 now idles at 42 degrees celsius. Overclocked to 1600 it idles at 42-43, under full load @1600 it doesnt go over 43.
In my old case i had 8 case fans, which made a whole lotta noise, so with this one i wanted it quiet. I put four 80mm case fans in (two front, two rear) and a 5 1/4 drive bay temp monitor/fan controller to run them. When its idling, the fans dont run, just the 5000rpm cpu fan, video card fan and thermostatically controlled psu fans. So its almost silent. When its under load, and the temp hits 43 degrees c. the fans kick in until the temp drops back and they switch off.
Gives the best of both worlds really, when im browsing or downloading or doing basically anything that wouldnt put enough load on the cpu that it needs extra cooling its quiet enough to be unnoticable, but when im gaming the fans kick in to keep the system cool. Since i usually either play games with the speakers cranked up (during the day) or use headphones (at night) i rarely even hear the exta fans spinning...
I picked up a motor speed controller kit yesterday, which i havent built yet, but will use that to control a 120mm blowhole and two 80mm side fans, so i can have them running all the time at around 1000rpm (quieter than the psu) to just give a slight breeze through the case, meaning the front and rear fans should only kick in after a lengthy period of gaming or benchmarking.

NB fan speed adjust with CoreCenter

Looks like it isn't possible to adjust NB fan speed with latest CoreCenter on a 865PE Neo2 with latest Bios.
CPU fan speed adjust works great.
Any help?

I've just tested Speedfan and this Program doesn't work also (and YES i've read the complete guide).
Is it a problem with the latest Bios 3.6?
