Problems: :O
2d tolerable but instable. Sysmon shows page faults, rising rapidly when programs are opened. DxDiag - crashes during d3d test most of the time. Quake3 gets to 2 seconds into the ID title before hanging.
Occasional 2D artifacts, system tray goes black and some colours reurn when you run the mouse over them.
Occasional series of small green vertical lines in the top portion of the screen on some crashes. IE works for a while and then crashes (windows closes it).

CPU voltage regualtion is RAGGED but within tolerances - 1.72-1.82v
3.3v +/- .1v
5.0v and 12V feeds are fine.
CPU temp reads 58-59 C
Lowering FSB on processor and RAM lowers stability -default clock fine.
Raising AGP voltage by +.1 aids stability.
Lowering Graphics card
core speed and memory speed helps a little.
Disabling fast-write helps a little.

Poor Nvidia drivers
Please dont say change my PSU - its within its tolerance.
Thanks in advance.

Ive got a 4 sats + sub creative stuff and a mic.
The mic is in the mic, and ive got a lead in mic in and one in mic out.
I downloaded the new drivers and the sound is gr8!

I still have problems loading windows and am getting repeated CONFIGMG windows protection error. I'm not too fussed about that because once its up and running, it runs like a dream.
Q.Any ideas as to why my 3dfx is so comparitively slow? (Yes I know I should go out and get a Radeon 9700 pro gti turbo ultra gold.........)
A. That'll be the z-buffer disabled...
I found some more info that might relate to my configmg problems here:
http://www.easttexaschat.com/_tips/VxD_drivers.htm
But sadly it didn't work for me...
Its interesting that ECS got SLATED over this configmg error and some bright spark soldered a resistor onto his board which seemed to work. It was put down to a SiS chipset needing to be at a certain temperature - i used this fix and it worked.
Could it be that a conventional system fan could be placed hear the nvidea heatsink to solve this problem? As configmg errors can be motherboard related, could this explain poor memory compliance? Could this explain its refusal to home my little geforce2 gts...?
And the answer is YES. The chipset cooler is inadequate. 8o
**The configmg errors have stopped.**
I used a standard 80mm case fan and modified it using a 2l plastic coke bottle so as to channel the air onto the heatsink without damaging it. Previously it was difficult to get windows to load. Now it has succsesfully loaded 10 times.
**I am now using the default memory timings without a problem - thats 6,3,3 Cas2.5**
Bear in mind that I tried these timings with my matroxg450 previously, and it resulted in crashes.
Now for the final test... I shall trawl out my geforce2 GTS - source of all my initial troubles with this board - could it be that the performance of this board was straining the chipset when it wasn't properly cooled, or is it still a device driver issue?
Well, during instillation of the drivers I got 2 VxD BSODS. I tried 20.xx 30.xx and 40.xx which all failed to produce an image using directx 8.1. Guess this board just doesn't like the card.

Really tough to tell from that little of info, is there more?
Does it boot at all? How often does it KP?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), does it KP then?
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Might try disabling some CPUs.
The cpus boot argument can range from 1 up to the total number of processor cores on your system.

A Newb's Poor CPU Overclocking; RAM Timings?

First, my system specs:
Intel Pentium 4 Prescott 2.8GHz HTT w/ 800MHz FSB
Thermaltake Spark 7+ Xaser Edition A1715 CPU Cooler
MSI 865PE Neo2-FIS2R motherboard (BIOS ver. 3.8)
2x512MB Kingston PC3200 DDR SDRAM @ 400MHz
Maxtor 6Y120M0 120GB HDD 7200RPM SATA150 8MB cache
Built-by-ATI Radeon 9800 Pro @ XT 128MB DDR 256-bit @ 415/744 (Catalyst 4.12)
Arctic Cooling VGA Silencer Revision 3
Creative SoundBlaster Audigy2 ZS Platinum
Sony DDU1612 40x/16x DVD-ROM
Sony CRX230ED 52x/32x CD-RW
Enermax EG475P 470W PSU(+3.3V = 34A, +5V = 40A, +12V = 33A)
I've done quite a bit to my video card in the past few weeks: replaced the stock ATI cooling with a VGA Silencer, flashed my Pro to XT status, and overclocked it mildly.
Just a few days ago I replaced the boxed CPU cooler with a Thermaltake Spark 7+ Xaser Edition A1715 CPU Cooler. Here's where I ran into my first snag: It didn't reduce my temperatures much. At idle my Prescott 2.8 ran at 48 or 49C with the box cooler, and runs exactly the same under load. However, with the stock cooler under load it would get all the way up to 69-71, whereas with this new cooler it only reaches 65-67. Still not what I was expecting with this cooler though.
I decided to delve into a bit of CPU overclocking. I increased the FSB 1MHz at a time, testing after each increase.
Except, I didn't get very far. I was using Call of Duty multiplayer to test, and I get visual errors starting at 203MHz. They're thin vertical white lines that flash for a second and then disappear. Also jagged polygons strewn throughout the screen, usually white or a pale color. When I clock back down to 202MHz, they disappear.
Using CPU-Z I get these values for my RAM modules:
http://mywebpage.netscape.com/ISBop/cpuz1.JPG
In case that picture doesn't work, they are:
FSB:DRAM = 1:1
CAS Latency = 3.0 clocks
RAS to CAS = 3 clocks
RAS Precharge = 3 clocks
Cycle Time = 3 clocks
Bank Cycle Time, DRAM Idle Timer, Total CAS, and Row To Column are all blank and greyed out.
I know that increasing the FSB also increases the memory frequency, so basically I'm trying to figure out if these artifacts are caused by the CPU or the memory. My CPU cooler has manual fan control and when the system is under load I run the fan at high speed, and the temperatures aren't getting that high, so it doesn't seem like the CPU is the problem.
I looked around for specific information about my RAM modules' overclocking abilities, but found little. I found the datasheet for my memory here(PDF format). I was thinking that maybe tightening the timings would enable me to push up my FSB higher. 202 as a limit is a little disappointing, to say the least.
My BIOS settings are as follows:
Performance Mode = Turbo(MAT)
DOT = Disabled
CPU Ratio Selection = Locked
DRAM Frequency = 400
Spread Spectrum = Enabled
CPU Bus Clock = 202
DDR Clock = 404
AGP/PCI Clock = 66.66/33.33
CPU Voltage = 1.3875
DDR Voltage = 2.60
AGP Voltage = 1.65V
System Readings:
System Temperature = 35C
Vcore:
3.3V = 3.184 - 3.248
5.0V = 5.088 - 5.167
12.0V = 12.081 - 12.408

what does 202 do for you? I mean I'm at 220.
RE the software?
What drivers? You mean graphics drivers? Different drivers haven't made a difference in any game. The artifacts appear once I clock to 203.
I don't know if I have the RAM set correctly. I was posting here to find that out.
By card voltage I assume you mean AGP voltage. Its at 2.65V. Vcore is at the lowest setting, 1.3875. I tried 1.4000 and 1.4150 but neither affected the overclocking ability either way. Still produced artifacts at 203.
How did you get to 220? What happened when you went higher than that?

Lowering the CPU voltage?

What kind os problems can I have if I lower the CPU voltage to, for example, 1.4V???
Will it cause stability problems?
Can I damage anything?
Please help.

You can only lower it so far before it will begin to act quirky and that can cause all sorts of problems. I am not sure if you will actually damage your hardware, but you may pooch your OS and be forced to reinstall everything. It is generally better to lower your multiplier if you are trying to lower power consumption. What exactly are you trying to accomplish?
RB
Ok I see...
I'm just trying to lower my CPU temps, but actually I do not know if temp is my problem. I got 2 BSOD while running prime95 with everything at stock. But I remember that when it crashed my CPU temp was around 52C. Isn't that too hot? I do not know...
And one of the times, after the BSOD, I tried to reset the machine and it did not post, giving me beeps and leds saying "memory problem"...
( I was having this exact beeps and leds problem EVERYTIME I tried to turn on the machine, but I had a low amps PSU. After I changed to this one in my sig, everything started to work fine, until this... )
Any ideas please?

Fluctuating CPU voltage

Hi
I have a MSI K7N2 Delta-ILSR (MS-6750) motherboard with an AMD Barton XP 3200+ CPU & 2 x 512Mb PC-3200 RAM.
Of late, it has started crashing with monotonous regularity. I have tried everything I can think of to identify the cause - without any success.
Today, on the off chance that it would make a difference, I decided to experiment with dropping the FSB speed from 200MHz to 166MHz. Before doing so, I ran CPU-Z to check the speeds. I happened to notice that the CPU Voltage was fluctuating between 1.60v & 1.664v. pcAlert4 shows the same thing - the other voltages are shown as 3.33v, 4.95v & 11.88v and seem rock steady. I have never noticed this fluctuation in CPU Voltage before, but haven't really looked.
Does anyone have any idea why this might happen? I am guessing that there is a problem with the VRM on the motherboard. Does anyone have any suggestions as to whether I can do anything about this?

A brief update before going to bed:
The system has now been up & running for a little under 9 hours - which on recent experience is pretty darned impressive!
However, I have dropped the CPU FSB speed from 200MHz to 167MHz (according to CPU-Z) - the RAM is running at 5:6 i.e. 200MHz.
When I tried to run "ORTHOS" (v0.41.110.18) with the default "Blend - stress CPU and RAM" test, it halted after less than 30 seconds:
Quote
1:FATAL ERROR: Rounding was 0.5, expected less than 0.4
1:Hardware failure detected, consult stress.txt file.
1:Torture Test ran 0 minutes 25 seconds - 1 errors, 0 warnings.
1:Execution halted.
1:FATAL ERROR: Rounding was 0.4997816086, expected less than 0.4
1:Hardware failure detected, consult stress.txt file.
1:Torture Test ran 0 minutes 28 seconds - 1 errors, 0 warnings.
1:Execution halted.
I ran the "Small FFTs - stress CPU" test, it kept going for just over 20 mins. before crashing - I assume that this stresses the CPU but not the RAM.
Quote
1:FATAL ERROR: Rounding was 0.4959945679, expected less than 0.4
1:Hardware failure detected, consult stress.txt file.
1:Torture Test ran 20 minutes 15 seconds - 1 errors, 0 warnings.
1:Execution halted.
I have now been running the "StressCPU" test on ORTHOS for 3½ hours without problem - I will leave that running overnight and see if it keeps going before experimenting with single sticks of RAM tomorrow.
It does seem as if the problem relates to the memory. However, I don't think that it is this particular memory since I was previously using 2 x 512Mb Geil sticks and had all the same sort of problems with that.
I don't understand why reducing the CPU FSB from 200MHz to 166MHz should have made the system more stable since I have left the RAM running at 200MHz in DDR mode.

CPU voltage on Delta-ILSR

Is there anyway configurations, software, etc... to give my CPU more power? 1.8volts will not let me get any higher than 2300 with stability. If not lets all beg MSI to add higher Vcore in next bios :D

The latest BIOS' 7.3 and 7.4 for the K7N2-ILSR Delta has solved the CPU Voltage prob - I'd imagine that they fixed this prob with new BIOS versions on other K7N2 boards too.

P6N Diamond CPU voltage fluctuations

Lately my CPU voltage has been acting up overclocked or not, sometimes voltage has been ok by restarting system but now will not and system crashes running smp program.
CMOS has been reset multiple times and voltages are fine from power supply.
The thing i am not sure of and maybe someone has some input here, Im still running the first shipped bios 1.0 and my processor is a GO Q6600 and im not sure if that series processor is supported though i know the older series Q6600 is supported and am wondering if that could be causing the problem though sometimes in the past everything has been ok but i have never flashed a bios before because it has not been needed.
Any input would be helpfull so i can get the smp running again.
Hope the board is not going out anyways, im not sure if it is still in the warranty period or not.

Quote from: Henry on 12-November-08, 15:01:39
I'm sure you've allready looked but by the CPU support list you should have 1.2 BIOS for the G0. B3 shows 1.1. You've had off & on problems with folding all along on that rig haven't you? Perhaps you should flash 1.2.
The list has been updated and no longer shows version 1.0 at all.
No problem just started recently.
Quote from: AaronYuri on 12-November-08, 15:04:06
Try setting 1.36250V or higher. I think you should try another PSU too.
I wouldn't recommend a BIOS flash in an unstable state.
Power supply voltages are rock stable but i may give it a shot i have an old 375 watt unit i can plug into the board to test and keep the Silverstone running all other stuff.
Processor has run stable @ 1.28 volts before problems started but i will raise voltage more just to see what happens.

MSI 990FXA-GD80 B6 Max CPU voltage 1.27Volts????

So I have updated to the new B6 bios but unfortunately cannot set CPU voltage higher than 1.27 volts in bios to overclock -.-.
PC specs:
AMD FX 8120
Corsair XMS3 DDR3 1600Mhz (not working at 1600 have to go down to 1066)
Corsair AX850W
2 ATI Radeon 5870 1Gb Crossfire
MSI 990FXA-GD80

Having the same issue here, only I'm getting up to 1.365v listed... https://forum-en.msi.com/index.php?topic=153820.msg1136534;topicseen
Use version 11.5... It works good.
Also, on many games with Bulldozer, some motherboards will BSOD, or on the 990fxa-gd80 you get insanely low performance. Such titles include Shogun 2, Portal 2, Deus Ex: Human Revolution and many more. On the ASUS Sabertooth, a user was able to correct all of his problems by rolling back his BIOS to version 0705, but that doesn't really help us here much, other than to say hopefully MSI will also be able to correct these issues in a BIOS update soon...
As for me, I'm shopping for Intel/Nvidia parts now. I'm fed up with this crap. It's been one thing right after another with my AMD build....Never had any issues with any other system I've ever built in my life (been building systems since 386/486 days; over 15 years), but this one has just been a nightmere...Nothing against MSI - I love their products and hoping to get at least a couple gtx580 Lightning Xtremes, if not also one of their fine Z68 boards.

Problem with CPU Voltage

Hello
I build new PC with:
i5-760
Noctua NH-D14
MSI P55-GD65
G.Skill 2x2GB CL7 ECO
Antec TruePower New 750W TP-750
TwinTech GF 9600GT
I have problem with CPU voltage as even when I set it for example to 1.201v in bios, under load it overshot to 1.256-1268. The best is when I oc`ed cpu to 4GHZ and set voltage in bios for 1.30v it overshot for 1.45v+! Not to mention that temps are skyhigh from that. It doesn`t matter if I try to put BIOS Vcore on 1.1v on stock because under load it still rise to 1.16. I turned off all eist, c-state, turbo boost, phase led and switch phase, set vdrop to low and still something is wrong here. I updated the bios under dos from USB stick to newest 1.9 version in order to update CPU micro code without error and it not helped. I want to know is that even possible to fix or should I RMA MB or CPU.
Minor problem is with sysfans as they power on for a second and turn off instantly to start working again when I see list on devices in post. After rebot when my monitor is switched off it takes something like 5 sec to power monitor on and another 5 to show bios, is that normal?

I have similar issues, it's hard to tell which measurement is the most accurate, there are 2 different measurements in the control center that don't match up with the figures set in the bios. The only way to be sure would be to get an expensive accurate multimeter but If you're only interested in running a stable overclocked computer without knowing the exact figures then get the computer running stable and lower the voltages until it starts to become unstable with prime95,
Or you could work the other way round, set the voltages so it boots but doesn't run prime95 for long, then raise the vcore and vtt one at a time until your happy with the length of time prime95 runs without errors. I'd be happy with 24 hours, I seem to remember errors creeping in at around the 9 hour mark on the setting below what I have it set to now.

How to increase cpu voltage on A75A-G35?

Please tell me how to increase cpu voltage on A75A-G35(I changed pstates in BIOS but voltage not changed!)? and then tell me range of voltage in 1-7 Pstates?

Quote from: MSI service FAQ
Q: I cannot adjust the CPU Voltage on my A55/A75 motherboard?
A: Due to a hardware limitation on this platform, you cannot adjust the CPU voltage. However, you can adjust the NB voltage which is the same on this platform.
(http://service.msicomputer.com/html/popup/techsup/formviewer.asp?esoformid=2987)
The NB voltage setting is below the "Advanced DRAM Configuration" and the only way to increase a cpu relating voltage on that board.

How to get higher cpu voltage during load when using "auto" with P67A-GD55?

I have a little question regarding cpu voltage: When i set vcore to "auto" i get a nice low voltage when idle but during load i only get 1.264 max and that is to low.
Is there a setting to increase the voltage during load and still have the cpu vcore set to auto?
Thanks

Quote from: Bernhard on 01-May-11, 15:25:22
OK, so you are able to set your CPU voltage manually. You need to consider that the auto voltages will compensate only up to a certain OC level, after which the user usually has to do manual adjustments. This auto compensation differs for each hardware combination. As HU16E suggested, try low VDroop and see if it helps. The other alternative is a BIOS flash, or manual voltage settings.
I tried low vdroop but it didn´t make any difference. But it´s ok, i can set the vcore manually but i was just investigating if i could get the best of both worlds with the powersavings auto vcore offers during idle

MSI 945GCM5 V2 how change cpu voltage

I have Dual-Core E2160 VRam CPU voltage 1.3.. its lowest? I dont know where in Bios can this be changed.. because iam on stock 1.8GHz and temp is still 70°C+ in idle. (but in bios its wrote 50°C)

The Alpine 11 is almost as weak as a boxed cooler. It is a most simple all aluminium cooler without any heatpipes that is limited to just 95W TDP max. According to Arctic it cools a i5-2500K 3°C better than the boxed one.
Measure temps under load and in idle with Core Temp and report back.

BIOS doesn't change CPU Voltage P55-GD65

I have a P55-GD65 with BIOS Ver 1.7
No matter what setting I put the the CPU voltage it seems to run in auto only. I have tried many combination's of settings that I have read on the forums but nothing seems to be working.
Has anybody had this problem?
Thanks,
Mark

Yes even when I have Intel C-STATE and Intel EIST disabled.
The voltage is much lower. I can't over clock because I cannot up the CPU voltage. I have the CPU multiplier at 21 and the clock at 155. If I go even up to 156 on the clock my system will blue screen.
When I put the voltage in Auto and monitor it and then put it in manual and crank it up to 1.45 and monitor it the voltage behaves as it is in auto. I have XMS 1600 memory and the Mugen B rev 2 cooler so I know that is not an issue. I might have a defective MB. I've been building PC's for years so I'm not a newbe. I've usually used Supermicro boards and this is my first MSI board. The board is very nice and if it worked it would be great. I was going to build another system with that board but am a little gun shy now.
Thanks for all your help.

CPU Voltage of 11.7V Why?

Hi,
today I looked to the command "dmidecode" to visit the cpu voltage. I saw that the voltage is on 11.7V, is that an Error? And the other thing I visited, is that the cpu clock is always on 2.400MHz, but the system utilization is very low (only few % on each thread). Why is that?
This is the output of the command:
Version: Intel(R) Core(TM) i7-3517U CPU @ 1.90GHz
Voltage: 11.7 V
External Clock: 100 MHz
Max Speed: 3800 MHz
Current Speed: 2400 MHz
I hope someone can help me.
Murmel

You should be using lm-sensors for these data. Even then, unless someone knowledgeable has verified each voltage output and mapped it to the correct motherboard sensors, you are guessing. To look at both endpoints, vcore and frequency, try i7z-git from the AUR. It reads the MSR values directly from the CPU.
