Fluctuating FSB/Multiplier

Hi, i've recently purchased a K8N Neo4-F motherboard along with a x2 3800 toledo, and i'm having problems with the FSB and mulitplier fluctuating. I've been checking it in core center, and the core speed often drops or rises by about 200MHz as a result of the changing FSB/multiplier.
I found a post on this forum with someone having the same problem as mine and with the same motherboard(and similar rig), and the suggestions were:
Quote
Set your power savings in windows to "always on" .
Disable CnQ in Cell menu in bios .
Click on the Cool'n'Quiet text in Corecenter and change from auto to user mode
I've tried them all but it didn't work for me. I've noticed the problem seems to get worse when i've had the PC running for longer periods though, its fairly stable at first for awhile. The temps are fine all the time, never seen it above 40c, the vcore fluctuates by up to 0.07v, I assume thats ok but i'm not sure. I have a Hiper Type-R 580W power supply, so that shouldn't be the problem.
Any suggestions?

Well i'm kinda glad its normal, not something i'm used to. Like starting up a game to be told my system has changed all the time is a bit annoying. I did have it overclocked to 2.8GHz for awhile, which runs perfectly stable. But when the fluctuating started I got a bit concerned and put it back to stock speed... but it still does it

Increasing FSB multiplier on a c2q q9550 with a p45 neo2 mobo

Is it possible to increase the FSB multiplier on my BIOS? I can only increase it until x8.5, coz im planning to OC it by increasing the multiplier and decreasing the FSB. My FSB right now is 450 MHz x 8.5 = 3.83GHz
Specs are on my sig
any help are appreciated. Thanks!

can the i7 920 raise the multiplier to it's stock multiplier?
Quote
Well [...], yes.
Let me be somewhat clearer on this:
This statement is still true, even for Core i7 processors:
Quote
You would need an 'Extreme' edition of CPU to raise the multi.
The CPU Ratio of the i7 920 can raise above x20, but only to a certain extend (within the limits defined by the Intel Turbo Boost Feature for this processor). That means x21 is possible, and maybe x22 (I am not sure).
To be able to raise the multiplier to (let's say) x33, you still need an Intel Extreme Edition processor. ---> Like this one:

Sempron 2.4 cant change fsb multiplier

hey i just built myself another computer with 2.4 sempron with MSI KM4M-V mobo... i think lol and i just updated the bios because when i go to frequency control etc in bios i cant update the fsb multiplier so the processor runs at the correct speed windows is only recognising the processor as a 1.33 anyone have any ideas? i updated bios with live update the bios is Award bios

KM4M manual
According to page 10 of that manual, the jumpers should look something like this:
SW1
|
|
SW2
That *should* give 166FSB, if the manual is correct, there is a statement that V1.2 of the manual has corrected the jumper settings.

Fuzzy Logic 4/Core Center - Changing FSB & Multiplier Settings

Just wondering if its at all possible to change the Multiplier settings or the FSB on the fly (in windows) - without having to restart and go into the bios to change them. I know that gigabyte has that feature for some of their boards.
The board in question is the K7N2-Delta ILSR
Is there a setting in the bios that needs to be enabled?
Thanks for the help if anyone knows.

FSB Multiplier

This is probably an absurd question, but I was always under the impression that the multiplied FSB should never go above 1000MHz, but I'm seeing people doing stuff like 300x8 in order to achieve 2.4GHz. If the multiplier of 8 is not the HT Frequency, then what is it?

The hypertransport bus is used for comunication between the CPU and all the PC components except for the RAM, a 800mhz hypertransport bus is much more than enough, the fsb (front side bus) is ued for comunication beween the CPU and RAM, the FSB value multiplied by the multiplier value is what determines your CPU speed in gigahertz.

no do not used it. you can use alternative like SpeedFAN, coretemp etc.

Max multiplier supported

I have an MSI MS-6334 (815M Pro) M/B with a Celeron 366.Currently my BIOS shows that the highest Multiplier Setting supported by it is 8.But in the CPU support page of my M/B in the MSI website shows that my M/B can support upto PIII 1G (10x100 Mhz.)How is it so?will the highest multiplier setting change after installing a higher processor.Also the page also shows that my M/B doesn't support Celeron 1G.But both the PIII and the Celeron have the same FSB:Multiplier ratio (10x100 Mhz.)Why is it so?Thanx in advance.

But the second question-
Why the page shows that my M/B can't support Celeron 1G (Coppermine) while it can support PIII 1G (Coppermine)?And what if I install a VIA C3?It's multiplier isn't locked.Can I overclock it to some other Multiplier Setting higher than 8x

Fsb rating for chipset @ 266

Hello guys,
I have an MSI platinum power up edition (core 2 duo E6600 @ 2.4), and just installed the dual core centre. The issue is that is says my fsb is 266, (default for Core 2 duo apparently) however my memory clock is set to 667 in the BIOS. (the fsb of the chipset is 266 confirming the dual core centre).
Am i right in saying that the chipset is running at 533 - slower than the memory ? Is there any way i can change the settings to match the ram (safely) ? As surely i can run the chipset at 667 to match the ram - as the spec says both chipset and ram can run at 667. Would i need to half 667 and enter that into the bios as the fsb for the chipset ?
My main reason for this sudden interest is that the dual core centre has a "game" setting increasing the CPU and fsb by a little bit - this little bit is very noticable on my system, it almost doubles the framerate in world of warcraft.

1. FSB:
The actual FSB frequency is 1066 MHZ (266 MHz*4). If you change the "basic" FSB-frequency in BIOS or through Dual Core Center (lets say 300 MHz instead of 266 MHz), the resulting "effective" FSB-frequency will be 300MHZx4=1200MHz. The FSB-multiplier is always x4.
2. Memory Frequency
Memory Frequency is always set in relation to the "basic" FSB-frequency. You can change FSB/Memory ratio in BIOS (cell menu) by specifiying a divider.
-->basic FSB*2*divider= DDR2 frequency
examples:
-basic FSB=266MHz:
266*2*1.5=800MHz
266*2*1.25=667 MHz
-basic FSB=300 MHz
300*2*1.33=800 MHz
300*2*1.25=750 MHz
I hope you get the idea...
Syncing FSB- with memory frequency is not necessary. To do that, you will need memory modules that support 1066MHz DDR2 frequency. The thing is, that modules like that are not officially supported.

MSI G41M-P23 FSB/core clock issue (HELP!)

Alright, so a few days ago I bought an MSI G41M-P23 with 8 gb of DDR3 1066 (PC3 8500) RAM (the standard for this board). My CPU is an E8400 (3.0 ghz). At first I wanted to maybe fiddle with some overclocking, which is where I realized that this mobo fails at. Not a big deal...but every time I attempted to up the FSB above 336 or so (this CPU's default is 333... x 9 = 3000 mhz), the system would not POST, instead it simply would loop on/off until eventually going back to defaults.
That was fine with me -- I don't need to overclock, really. However, I noticed something odd in the BIOS. The CPU speed, which according to the fsb multiplier was the correct speed (2997 mhz), was very not correct in the CPU info section of the BIOS. There, it listed the speed at 1.8 ghz. Thus I decided, for the heck of it, to take at look at CPU-Z at this time.
This is what CPU-Z is currently telling me (I have a screenshot, but I can't seem to post it here):
In the "Clocks" section (bottom left of the main tab in CPU-Z)
Core speed: ~1894 mhz
Multiplier: x 9.0
Bus Speed: ~210 mhz
Rated FSB: ~842 mhz
The RAM speeds and ratios are correct, though, given the FSB:RAM ratio (it would seem). Ram clocks in at ~333 mhz, which with a 5:8 ratio should put it at 1066...I think.
So now CPU-Z and part(?) of the BIOS is showing me the wrong CPU speed (1800 mhz). It's also listing my FSB at 200 mhz despite the fact that my I set it in my BIOS at 333 mhz. The 200 Mhz adds up with the incorrect core speed, as 200 X 9 = 1800. If I go back to the BIOS, it lists the FSB correctly, and the POST screen displays the correct FSB and multiplier, but again, the CPU info screen of the bios is reading 1800 mhz, while listing the FSB as 333. I don't have any speedstep/CE1/other modifiers turned on, and this reading is currently under normal load (read: not idle). I'm at my wit's end here.
Is this board not saving my FSB speeds in the BIOS? Is there any way to fix this issue? I apparently have the most up-to-date BIOS according to CPU-Z and MSI's support website. I have not tried every setting of the OC switch yet, though I have tried a few (200 -> 333, for example) and all have resulted in a system that will not POST, and leaves me having to reset the CMOS jumper in order to get it to boot again (as opposed to the looping/defaulting cycle mentioned earlier).
Can someone PLEASE help me? I just reinstalled Windows 7 x64/all my programs because of this new board...and I really, really don't want to do that all again.

Well, I heard back from MSI. They are just as confused over the BIOS version as I am, apparently. V30.8 is not what is supposed to be on the board. So, rather than flash it and hope that it works, etc., I decided to simply return the board, as I've only had it for a few days, and bared used it. Something is clearly wrong with it to have an "unknown" BIOS installed.
I went ahead and ordered a new CPU and mobo entirely...Core i5, too. No MSI board this time...only because they didn't have a board in my price range. I wanted this upgrade to be something easy and simple so I wouldn't have to do that.. oh well.
I do find it very strange what's happened with this board, though....I've never before heard of ordering and receiving a board with an unknown BIOS on it...even according to the manufacturer. Maybe an out-of-date BIOS, but not something completely off the radar. Still, thank you again for your help.

975 Platinum Powerup BIOS & Ram FSB

i have the 975X Powerup edition
dual core 805
OCZ 5400 Gold 667 RAM
my ram only comes up as 533MHz but is has occasionally run at 667MHz. when i go into the BIOS and look at RAM FSB multiplier i can not change it of AUTO as it is read only.
any help would be appreciated.

You should have a read of this review, to learn more about your processor but the ratio will not go higher then 1:2 so you may have to push up your FSB to get more out of your memory but I am not 100% certain on this. Maybe someone who is already running with your proc will post for you.

Diamond Plus; Cell Menu CPU FSB Set at 250 x11 but Board Running 200.9 x14

I have FSB set at 250 with the CPU multiplier set at x11. Memory is set at an FSB / DRAM ratio of 1:1. The memory modules are in slots 1 and 2 (green / purple). While in the BIOS Cell Menu it is reporting Memory frequency at DDR500 and the CPU at a slight underclock. This agrees with the above settings. However, in BIOS / Standard CMOS Features / CPU Configuration, it shows the CPU running at 2816Mhz with a multiplier of x14. This is equal to the settings (200.9 x14) that are applied when "Load Optimized Defaults" is loaded and saved. All of the settings in the rest of BIOS setup are definitely set to Manual and the setting values as noted in the first sentence.
CPUZ is also reporting a FSB of 200 with a multiplier of x14. It's showing the memory as PC3200 and running at DDR400 which makes sense if FSB is really running at 200. Long story short, it's reporting everything at the stock settings as set by "Load Optimized Defaults". It is correctly showing the memory in dual channel and the command address rate at 1T. This is the latest version of CPUZ. I had an older version saved on CD. I tried this old version and it reported the same thing.
I have all of the dynamic overclocking options, wakeup options, cool n' quiet and automatic fan speed controls (except northbridge) disabled. If there's any other options that could throttle down the CPU I sure couldn't find them. Even if there were, my CPU is running atb 39C at idle so it shouldn't kick in any thermal throttling. When I flashed to the version 1.19 BIOS version at MSI Tech Support's direction to solve the "phantom modem" issue, I took the extreme route to clearing CMOS; powered down, removed or disconnected all the components, pressed the clear CMOS button, removed the battery for 30 minutes, pressed the clear CMOS button again, reinserted the battery, pressed the clear CMOS button yet again, reinstalled / reconnected the minimum required components, flashed the BIOS, cleared CMOS again, cleared nvram, loaded optimized defaults and saved, manually adjusted all the settings, reinstalled / reconnected the remaining components.
I'm at a loss to explain this. MSI Tech Support says they can't help me because this involves overclocking and they're not allowed to provide advice.
Anyone have any ideas as to what could be causing this?
Thanks in advance for any help provided.

I've been experimenting with different combinations of FSB / Multipliers / Memory dividers. My best performance is with the CPU at 250 x12 for 3.0 GHz, and memory still at 3-3-2-8, 1:1 and 1T. This is all at stock voltages and I'm not willing to risk frying anything by raising it even a little bit. It's running fast, smooth and cool. That's all I'm looking for so that's as far as I'm going to take it.

I'm getting the same anomaly with the value for CPU Fan. That's the chipset fan speed for sure. It matches the BIOS reading and it's the only fan I have plugged into the mainboard. Everything else is running from a rheobus.
The NB temp on this mainboard is really exceptional. The NB on my old DFI SLI-DR routinely ran in the 48-49C range. I guess the MSI cooling solution is pretty efficient. One other thing though, I'm using Arctic Silencers on both of my graphics boards. The intake fan on the "slave" board is directly above one of the chipsets. That may be drawing an additional bit of heat off of the chipset.
As far as the voltage values, I'm getting the same skew with a different mainboard, BIOS and PSU so this looks like an Everest issue.
IMHO, if your machine isn't doing flakey things that can't be attributed to anything else then your PSU is adequate. If you do go with the Diamond Plus and SLI, I would suggest upgrading the PSU. It seems that the 1 kilowatt PSU's are all the rage now but in reality 700W is more than adequate. Adjustable potentiometers must be nice if you know what you're doing with them. I don't so I don't bother looking for that feature.
Hope this is helpful or at least of some interest.

Questions about OC and upgrading my 790FX-GD70

Hey Guys,
So Ive had this board for a while now (790FX-GD70) and am looking to throw some new parts on it, I want to throw the 1100T CPU on there (Unless MSI wisens up and enables AM3+ like they did for other boards) and was to throw in some 1600 or 1800 ram, Ive got a couple concerns though.
1. Ive never updated the bios on thsi board (I think its 3.04), frankly Im not a huge fan of doing it and avoid it unless I absolutely have to, will I need to update the bios to throw in a thuban?
2. The boards specs say that the board supports 1600/1800 member but only OC'd, so that means I need to OC the FSB right? But Im not sure how much overclocking this boards FSB can actually handle, if Im not mistaken for 1600 it will need to be 2400-2600 and even higher for 1800 memory. Can the board handle it? Will I have some major FSB heat issues?
2a. What do I need to overclock? Do I need to increase the bus speed or the fsb multiplier? What voltage do I need to set for the FSB at thoes speeds?
2b. Bus speed affects cpu clock as wel ldoesnt it? so if I boost the bus then do I have to throttle back the multiplier?
My goal is to have the 1100t running at around 4gz and the memory will either be 1600 or 1800, it depends what I find with good timings at a decent price.
Thanks guys!

The Guide will come in handy. I have an 790FX-GD70 that I have done plenty of OC settings with my original Phenom II X3 720BE, and now my X6 1090T.
Overclocking is a trial and error project. When you get a better understanding about the effects of Overclocking you will learn that it's about stability with an overclock, and not setting records. Well.. unless record setting is a part you want to play with. Stability.. there are programs to test you overclock. Many of them, some available here in downloads. Prime, Futuremark, OCCT.. choices to help you test for stability. Play safe, step by step.. that way you avoid damaging your system. There are a lot of Overclock examples on the net. Search the board and overclock. The board is now a couple of years old.. but it was a hot.. overclock board. You can find it even with your CPU as examples to learn from.
Here's one for you.. you'll learn! You stated 1600-1800 memory speeds. OK, it's an overclock. But, the question is? Do you get a gain? Is 1800 really quicker than 1333? The number is bigger. 1600, or 1800 is bigger than 1333, or 1066. So, it must mean it's better and faster, right? Well.... if you compare reads and writes between 1333 and 1600 the gain is little or none. There are different CPU crunch uses. Like burning video or playing a game. Different demands, different setting results. The AM3 CPU is made for 1333. In some Overclocks because of timings... 1066 could offers quicker results than 1600. It's trial and tests. Not just CPU but Memory and more make an Overclock. Welcome to Overclocking. It's fun and done within limits... you will get more out of what you have. Me.. my best Overclock to date? Results I see from my 790FX-GD70? I have run 3.8 stable... and my SSD's are a better OC than tweaking my speeds. Both together... I have amid OC and am very happy.
Good Luck

790GX-G65 worst experience of all time

So here i was an avg gamer. The only game i ever played was Arma 2 That game was CPU intensive and could only max out at 31-35 avg FPS.
My build specs were:
MSI 975x platinum edition
core 2 duo E6700 (2.66ghz OC to 3.10ghz)
4gb ddr 2 ram 667mhz
maxtor 250GB
Antec Neo Power Blue 650 watt PSU
ATI HD 4870 (Palit sonic dual edition) 512MB
My friend showed off his gaming rig. 4gb ddr3 and AMD phenom II x4 945.. His benchmarks in Arma 2 were great. I had just enough money. so i sold my Mobo, cpu, and ram and bought the following:
MSI 790GX-G65
AMD phenom II x4 945 (95watt) (http://www.newegg.com/Product/Product.aspx?Item=N82E16819103809&cm_re=phenom_II_945-_-19-103-809-_-Product)
and G-skill 2x1GB DDR3 1333mhz
500GB Samsung spinpoint f3
I removed cleaned and properly installed everything... And this has been my experience so far....
tried to boot from my old maxtor first just to test out my new cpu's power. had to change a few boot settings. when i got onto the logon screen BAM a gfx glitch (pink looked like a thumb print) and pc was completely unresponsive...
i thought it was my gfx card (i had just rma'd the thing because of bad memory problems) so i couldnt believe it.. i quickly shut off to prevent further damage... to my surprise when i rebooted to bios, no gfx glitch. i figured it was the drivers.. my friend suggest i install windows 7 on my new spinpoint and start fresh..
I spend 3 hours trying to install windows 7 because the disc would never finnish. it would freeze after the logo... i went back to bios changed a few things unplugged devices... finally i thought it was the new ram.. tried out both ram chips individually in dimm1 and dimm2 one by one to no avail. windows memory diagnoistics reported no problems. We finally managed to load it after we found out the OC switch on the mobo was on.. weird the CPU was running at 3.30ghz instead 3.0. But when the completing installation stage started windows the pc would just randomly reboot also causing the installation to be corrupted forcing me to try again and again and again
So i put vista in, it finally installed but it would crash when "adjusting windows performance". This told me it was a hardware problem... me and my friend narrowed it down to the cpu/mobo. What fixed my problem was lowering the multiplier from default (x15) to x13. To our surprise i could finally logon to the new windows. My friend told me to instantly download prime95 and run a test to see what was going on.. Also to check CPU-Z and temps
Almost instantly after hitting the start button in prime95 the pc crashed. So fast it felt like the start button was more like a "shutdown" button :O
CPU-Z said that the cpu voltage was at 1.456 and avg around there... He told me it shouldnt be like that since his 945 avgs out at 1.3 or less
Changing the bios "CPU Voltage" would make the pc not startup.. (screen would stay black) i couldn't even get into the bios. So i had to "clr CMOS" and try again.... and again.... and not ONE setting i tried for the "CPU voltage" was successful...
Finally i installed windows 7 and would you look at that.. it installed. But anything higher than x13 muiltiplier would cause crashing in any programs... even sometimes starting CPU-Z would crash.. watching 1080P videos would crash... everytime everytime...
and windows was so unresponsive at times with these weird stutters that lasted 1-3 seconds every 5 seconds. It was ridiculous. Why should i have to underclock my new cpu from the default values to 2.6 just to start my OS..
We Tried everything buying new thermal paste reapplying thermal paste (6 times) changing coolers, i bought the best paste out there (artic silver 5) nothing...
Finally changing the mobo to optimized defaults again and going directly to the "CPU Voltage" setting changing it to 1.284V my mobo booted without having to clear cmos. BUT HERE IS THE SHOCKER: temps where at 85C-90C range like 200F !!!!! i couldnt believe it.. so i shut off instantly and clrd cmos..temps dropped down again to the low to high 40's.
Here i am now.. with an underclocked overvoltaged phenom II x4 945 edition barely able to run windows. My bios is updated to the latest wich is 4.10 and i dont know what else to do. Faulty CPU? doubt it. All i know so far is that my mobo is just sending waay to much power to my cpu causing the quick overheat and shut off. I've spent 5 miserable days since i got my new build trying to just run the default values. NOthing... so i'm contacting you msi guys and the people on these forums to please guide me. my last 5 days have been hell..
Anyways my friend says my new cpu is not on the mobo support list which is true, but the other 945 is. not the new revision i have so maybe thats also a contributing factor....
O and another weird thing.. sometimes i can play arma 2.. performance is not too good because of the hiccups, but it doesnt crash my pc.. Except when i tried to raise the cpu/fsb multiplier up to x14 it would crash sometimes.
ANYWAYS please help me figure this out i dont understand all these experiences dont make sense to me.

Well, this is the motherboard i have:
http://www.msi.com/index.php?func=proddesc&prod_no=1739&maincat_no=1
I dont know how to check if its a "winkie" board.?
Anyways. I can confirm that flashing the bios back to 4.0 did nohing for me.. Exact same results. I also changed my PSU and got exact same problem.
So so far its not:
Ram
PSU
Cooler (i'm pretty sure its not the cooler because i went from my antec cooler to reapplying paste on my antec to stock cooler to reapplying paste on stock cooler twice. After 4-5 times playing with the coolers and paste i'm pretty sure its not the Cooler/paste causing the issue.

And 97C isn't possible, the board should shutdown at about 70C.
I gurantee you this is what the motherboard monitoring stated.
yes 45C isnt good i know that. And i cant seem to do anything about it. The weird thing is the first test run the temperature was at high 30's second try with reapplied paste bios said temperature was at the low 20's (21-23C) But as i booted OCCt temperatures readings said 70C which made no sense to me.
So i finally put the stock cooler and so far all the readings have been in the 43-47C range. Except for that one time i changed the "Cpu Voltage (V)" to 1.2840 which btw was the highest setting possible in the bios and caused my readings to go off the chart at 97C range. I can confirm doing this over and over will give me same results. All the higher settings are in red or "Not recommended" and also force the mobo to not boot. 1.2840V is the only setting that i can change aside from auto that will alow my mobo to reboot. And its also the highest thats not in the red zone
I'm now able to get on with you guys because the multiplier is at 13X and temps in OCCT AND mobo are conistent with one another reading at 45-47C.
My friend is suggesting me to get a new mobo but before i do i want to know if it's really the motherboard or the cpu... I bought this cpu last week and i can still RMA it if thats the problem.
