Is Cool 'n Quiet stable?

I run a K8N Neo2 Platinum (MS-7025) with 1.4 bios, 3800+ NewCastle CPU and Kingston HyperX 400MHz memory.
The setup works like a charm, but when I enable "Cool 'n Quiet" it seems to cause lock-ups and reboots.
The system is NOT overclocked, everything is set to AUTO in BIOS, except for memory which has been set to a bit slower settings than SPD reports.
When I have Core Center open on screen to watch what Cool 'n Quiet does, it seems like most of the time it reports 200MHz x 5.0 at idle, but when I start up an application, it can peak to 380MHz x 12 ?
Neither memory nor CPU should be able to handle that kind of FSB clock, so is it a system bug that the clock peaks at way above 200MHz? I really don't DARE to use "Cool 'n Quiet" for that reason, I need a stable system that doesn't hang or reboot in the middle of working.
Later,
Anders.

Andres,
I'm not getting the BSODs but the fluctuations do have me concerned. This thread is interesting. Blue screen caused by Vcore flucuations?
Raising the Vcore from 1.50 to 1.525 or 1.55 does seem to help stabilize my system but the CPU temp goes up. I've got a Thermalright XP-90 on the way so heat shouldn't be a problem.
===============================================
What I've found so far...
Cool & Quiet disabled in the BIOS.
Start CoreCenter running.
Start Speedfan running.
Start WCPUCLK
Put a full load on the CPU. (seti@home)
Just moving the mouse around causes a few alarming fluctuations seen in CoreCenter.
WCPUCLK doesn't register the fluctuations but I'm not getting BSODs.
1) Open CC. Click on CoreCenter , the program title button.
2) Click User
3) Set the fans on high
4) Click Apply.
Now the Vcore and FSB stabilize.
It appears that C & Q is turned off.
===============================================
It looks like what the other guys have been saying...Don't use CoreCenter except as a reference to help set up other programs like MBM and SpeedFan. Hmmm...RightMarks RM clock also sounds interesting.
Having a quieter system with Cool & Quiet turned on in the BIOS is nice. I'll have to do more testing to see if its stable. If C & Q is still causing instability after raising the CPU VID to 1.525 in the BIOS...I'll leave it off...Cie La Vie.

Lockups caused by Cool and Quiet?

Since a few months, I have a MSI K8T Neo2 FIR motherboard with an Athlon64 3200+ (Venice) CPU, equipped with 2x512 Mb dual channel memory. No overclocking or any non-standard BIOS-settings; BIOS version 9.1. The system works great, but for one thing: I had frequent lockups...
After some time, I started noticing that my lockups occurred only when the system (running Gentoo Linux) was not doing very much (idle, or only doing some browsing with Firefox). Because of that, I started suspecting that my Cool and Quiet-setup had something to do with it: the lockups occurred when my system was running at 1000 MHz, never when running at 2000 MHz. Since I turned off Cool and Quiet (in the Linux kernel, I didn't touch the BIOS-settings) a week ago, I haven't had a single lockup, even though I've kept my computer running 24 hours a day mostly. So I guess my guess was right.
Can anyone explain what exactly is happening? Why is my system less stable when in 1000 MHz than in 2000 MHz? Can I do something to make the 1000 MHz-mode stable and return to running Cool and Quiet?

hi,
i have the same problem with the same chipset. (even if its another mb)
your post has been a big hint because after my lockups occured i tried to reproduce them with system/cpu torture tests but have not been succsessful. after that i declared that my system has been miraculously cured and went back to normal (i.e. mostly idle) usage and. bang, lockups again. so i disabled cool'n quiet for now and will see if that helps.

Basic stuff -- BIOS version, Cool 'n' Quiet working?

Hi,
Okay, my new PC is up and running stable in WinXP Pro. Here are some very basic noob questions:
-How exactly do I determine my BIOS version? I thought I had v. 1.0 based on the loading screen during boot up, and SoftSandra, but MSI's Live Update says I have an equal or newer version than 1.2.
-How can I tell that Cool 'n Quiet is functioning properly? In Core Center, it appears that the CPU fan speed increases under load, but it doesn't happen right away so I'm not sure. Also, the CPU fan speed slider stays in the position I put it in manually, even after I switch back to Cool 'n Quiet (maybe this is just a GUI thing).
BTW -- I installed the Hyperion 4-in-1 drivers, enabled Cool 'n Quiet in the BIOS and set Windows power management to "minimal" -- is there anything else I need to do to enable Cool 'n Quiet functionality?
Also, should I just control the CPU fan manually through a drive bay fan controller instead of through Cool 'n Quiet?
Thanks,
-Ross

Hi
Glad to see we are down to minor bits and bobs.
The bios version should be at top of first post screen. use pause if its passes to quick.
BUT, live update checks what version you have, if there is a newer version it will tell you. there is a 1.33 available from MSI, but not on live update yet.
There are various threads on C & Q, I don't use it, but some who do like it, others confused by it, you have obviously read the threads. So you know more than me !!
Hyperion 4 in 1 is the best driver, if C & Q is working for you I would leave it be, the fan will speed up or slow down on temp. That will take a few secs time lag as chip heats up, or cools down. As long as CPU temp stays within norms, I would think is is working normally.
Enjoy it

Phenom II x3 720 BE doesn`t run Cool`n Quiet

Hello. Almost a week running my new x3 720 and seems to be OK. Temps are 19ºC on boot, 31-32ªC idle and 37-39º running Photoshop CS3 with some heavy image files, 80-120Mb. Just for try, I did overclocked it up to 3.2 Ghz (200x16 and 1.47V) and temperature went up to 46-47ºC. ¿Is this normally? I did it slowly, mounting x0.5, 14.5/15/15.5/16 and rebooting every step. First I changed voltage to 1.5V, when I reached the3.2 Ghz I went down a little, at 1.47. Stable and running great. However, I don`t think 46ºC are better than 32ºC, so I get back to its original x14 and 32ºC.
Also, just for try, I boot and enabled the Cool`n Quiet. Never did it before with the others Athlon x64 Dual Core, I never saw what`s the difference. Now, my K9N2 sli platinum can`t activate this function. I tyred several times, enableling and rebooting and nothing. Seems the same mobo is deactivating this function on the reboot.
What`s this?

Florin

Hello. I`m running Win7 x86. Really, that`s only curiosity, isn`t my intention to use that feature. I only try to see if everything is running normally. May be that: on Control Panel/Energy options I activated High Efficiency. Could be.
No OC, I don`t want more heat. I just figured that by mistake I used a different thermal grease when I upgraded the new Phenom II x3 720 BE, using a generic one instead of the OCZ one, much more better. Later, I`ll repace it.

Strange Cool 'n' Quiet behaviour...

This is kinda odd. On my MSI K8N Neo Platinum, Cool 'n' Quiet works just fine when I'm running at 10x240 6:5 (FSB:RAM),. However, when I'm running at 8x300 3:2, the computer simply refuses to load Windows with CnQ enabled...it quits right before the login screen. At both settings, the CPU and RAM speeds are the same (2.4GHz and 200MHz respectively), and I've kept the timings, voltages, and HT multiplier (3x) the same in both cases.
I know it's not an issue with 300MHz FSB being too high, since with CnQ disabled I can easily boot at 315MHz and it'd be rock stable 24/7. So I'm stumped as to what could be causing the failures when CnQ is enabled with the second set of settings.
BTW, system specs are in my sig (click the link), and I'm using the official 1.3 BIOS.

Tritium,
I was under the impression that cool and quiet and overclocking simply do not mix.
The fact that you could even get it to work at 240 is amazing to me.
At 240, what were your other boot settings (initial cpu mult and initial cpu voltage especially).
The reason why cnq and overclocking usually don't mix has to do with cpu voltage (though correct me if I'm wrong). cnq works as follows. a tiny "cpu driver" installed in the OS communicates with the BIOS, at OS startup, to obtain a list of possible cpu states. Each cpu state is a combination of cpu voltage and a cpu multiplier. For example, the states that I have on my non-overclocked 3200+ newcastle are something like (this is from memory so don't quote me):
11x (2.2 ghz), 1.5V
10x (2.0 ghz), 1.4V
9x (1.8 ghz), 1.3v
5x (1.0 ghz), 1.1v
Now, let's note that nowhere in the above states was there mention of HTT. Just cpu multipliers. It seems that cnq is *assuming* that HTT is kept at 200. But what happens when (for example) you bump HTT to 240? Let's redo the above numbers. The key is that ghz changes, but cpu voltage remains the same. THAT IS THE KILLER.
11 x 240 (2.64 ghz), 1.5V
10 x 240 (2.4 ghz), 1.4V
9 x 240 (2.16 ghz), 1.3v
5 x 240 (1.2 ghz), 1.1v
Note that with HTT overclocked to 240, which cnq is ignorant of, it's trying to run at higher and higher ghz values, without being given correspondingly higher cpu voltages. For example: at stock, no overclocking, we have 2.2 ghz at 1.5V.
But with 240 HTT, we have one of the states being almost as high a ghz value (9x240=2.16ghz) yet only being fed 1.3v of juice. 1.3v is very likely not enough to safely run 2.16 ghz (to give just an example).
And all that gets magnified with HTT greater than 240.
That's my theory on why cnq and overclocking don't mix.
I very much hope I'm wrong, by the way.
What would help is if you could run cpu-z on your stable 240HTT system, and report the above values (cpu mult, htt, cpu voltage) for each state that cnq shifts between. (run a light, moderate, medium, and heavy cpu workload to get it to switch between states...but you probably already know that).
What values do you see? Let us know...I'm very interested to see what your cnq states are at 240HTT...thanks!

Cool N Quiet still not working

Athlon 64 3000 (and standard cooler)
MSI K8T Neo-FIS2R
1x512Mb Corsair XMS3200LLPT
2xSamsung SP0812C 80Gb SATA (connected to promise controller)
Zalman 400W PSU
Samsung SM552-B DVD/CR-RW
Windows XP + SP1
I've upgraded the BIOS to 1.1 and activated the cool n quiet mode. I've also downloaded the AMD driver (1.1.0.0) and installed that.
The CPU still runs at full speed. Have I missed something, or is it just pot luck whether this works or not?
Any help would be appreciated.
thanks,
Neil Urwin.

I just flashed to 1.2 and stilll no CnQ.
From other posts I'm wondering if the problem is related to one or both of:
Win2K + Athlon 64 3000+. That's what I have and others with trouble seem to
have the same. I tried reloading the AMD drivers, removing CoreCenter
and the only thing that works ever is the fan speed control. I never get the
extra folder in power options under control panel. Maybe since the Win2K
AMD driver is so old it doesnt detect the cPU properly and therfore doesnt start up?
I may still switch the CPU fan over to the Zalman CuAl since the retail AMD fan has a loud hum at 2500-3000RPM. But the reduced wattage and heat is worth trying to get if possible.
I already ordered more RAM and WinXP Pro from newegg so I guess I can see
if its the OS level/AMD drivers also fix the problem.
Overall I'm happy with the board. Its stable under Linux (RH 9.0) and Win2K under prime95 tests for hours. Haven't had time to try day long tests. Certainly stable under hours of BF1942.
For those of you hyper about RAM settings checkout the Ace' s hardware test.
I'm a bit suprised that it matters so little for the Athlon 64 but it's nice to hear.
Though I'm always amazed at people paying huge sums for better RAM for meager performance improvements- especially on real world programs and games.
http://www.aceshardware.com/read.jsp?id=60000306
AMD64 versions of RH Fedora Yarrow test failed to detect I had a graphics card.
Wierd since /proc seems fine. Anyone have a favorite AMD64 linux distro that works well installed from CDROM or ftp? I may just wait- little to gain at the moment suffering through beta quality software/OS.

Cool'n'Quiet not working like it should!

Well, I decided to try Cool'n'Quiet to see how much cooler and quieter my system would get. So I enabled it in BIOS and set Windows power management to Minimal, and watched the clock speed and voltage go down as the CPU load went down.
It stopped at about 1.3v and 1800 Mhz. It won't go any further! My friend practically has the same setup except he uses a 3000+ ClawHammer, and his clock speed and voltage decreases much more than mine. I've read that the clock speed should hit 1000 Mhz.
To answer some possible questions, yes, I have installed the latest AMD processor driver and yes, the CPU load is under 10% when I'm checking.
Thanks in advance!

If you install the latest beta BIOS 1.2B12, you will see that CnQ can drop the multiplier down to 5. But some people have seen instability with that BIOS. I have not.

How to disable Cool N Quiet driver when it isnt in the bios or registry for Roxio game capture?

1. HP G60-120 US Notebook PC
2. Windows 7 32-bit
3. No error messages
4. No changes before issue occured.
I was told by Roxio (company of the capture card I bought to record gameplay on my Xbox) to call HP and get my Cool N Quiet driver disabled after I updated my other drivers and still had problems with my capture card. Can somebody tell me where to find it other than in the registry and bios because it is NOT in there and I have looked already more than 5 times or if you know where I can get it remotely disabled. HP cannot remotely disable it because I just talked to them and they don't have the power to do that.

No, Corecenter is almost useless and is NOT needed to "activate" Cool n Quiet. The best it can do is tell you fan speed and temps, and even that is questionable. It will also tell you clock speed but you can get that from right clicking "My Computer" choose Properties, go to General tab, note mhz displayed there. If it is about half of full clock speed for your CPU, then CnQ is working right. If it shows full clock speed, then CoolnQuiet is NOT working and you need to re-read Mr. Woo's original post which gives details about how to enable it.
Next, about fan speed. You have to understand that CnQ does not have anything to do with fan speed directly. Unless you have fan speed control disabled in BIOS, then your fan is going to control as you described whether you have CnQ enabled or not. In BIOS, in the H/W Monitor section, there is a place to enable or disable fan speed control - it's called CPU Smart Temperature Monitor or something like that.
As long as it is enabled and your fan is compatible and hooked up right, the fan will ramp up and down to control temperature. This is independent of CnQ. And it is independent of Corecenter. Disable CnQ and shutdown CoreCenter, the mobo still controls fan speed.

AMD cool n quiet

Can I get some BIOS with AMD Cool n Quiet option enabled?
I get irritate when my A8 5550m cant get higher than 2.1GHz when the CPU can handle even 3.1GHz. I can fix this with restarting only, and it get back to 2.1GHz when I power on my laptop
G405s-7577 users. Thanks.
nb. Sorry for my bad english

64 bit I hope. Go into the device manager and look for the processor. Right click on the processor and choose properties then driver, then driver details. It should say amd processor rather than generic processor. The driver name should have amd in it (amdk8.sys) and not just processor.sys or something generic. For mobile processors the correct name is PowerNow! not Cool 'n Quiet although I cannot recall if the zv5000z actually uses a mobile processor or a desktop processor. I believe it is mobile.

SB Audigy 2 ZS and AMD's Cool'n'Quiet = Incompatib

Hello! Is anyone using these two combines on their machines? If so, then do you have any problems like crashes, blue screens, etc. especially after your computer speeds up overnight of idleness/long slow downs? I seem to have them in Windows XP Pro. SP2 with all updates, latest non-beta Audigy 2 ZS driver, etc. No problems if I disable AMD's Cool'n'Quiet in CMOS. Thank you in advance.

Just for kicks, I decided to install this card on a Dell that I happen to have around.. the specs are above and beyond the configuration of my regular computer (whose specs are above and beyond the specs listed for the Audigy 2 ZS Platinum).. and I am unhappy to report that the same freezing problems occur. I am still unable to use any web update features for ANY of my software, and I am still unable to record in 24 bit audio.

Cool and quiet can't be disable?

Hi, Is it me or cool N quiet can't be disable?
on CPUZ and coretemp i keep seeing my mhz drop, i want to disable it to run overclock test. But it still doing it after i adjust FSB and landed on 3640 mhz. I have read it should be disable.

Crackling Issues with AMD Cool'n'Quiet and Intel SpeedS

After enabling AMD Cool'n'Quiet on my Vista 64 computer ([url="http://forums.creative.com/creativelabs/board/message?board.id=Vista&message.id=2093">see this thread[/url]), I noticed that I had crackling in my audio from my Creative X-Fi. I put my Minimum Processor State back to 00%, and the crackling is gone. With both Minimum and Maximum Processor State on 00%, I have no crackling issues. I haven't tested Intel SpeedStep, but I would imagine that will also cause this problem. Can anyone verify this?Message Edited by dypsis on 03-25-200706:32 PM

I am running MSI K8N Neo Platinum/SLI 64FX? with 4gbram?I have never really used the cool n quiet utility becasue it always seemed to make the motherboard fans whine somewhat, for this purpose I enabled and disabled cool n quiet several times, and I honestly didnt hear any difference in sound, albeit the fan whinning was there. I dont know if this is conected or not, its possible cool N quiet creates other noise as well. I never did like the util. But, it might stand to reason that if the utility was creating voltage or signal variations it could cause the rice krispies syndrome so many people have been talking about. Have to get some more feedback on this issue.

Which is better : Enabling Cool'N Quiet or disabling it ?

Hi !
I enabled the Cool'N Quiet , but the CPU-Z shows the CoreSpeed 1004.9 MHz , is that because enabling the Cool'N Quiet ? If yes , isn't it better that the CoreSpeed has high MHz ?
Any explanation plz ? because I am confused and newbie with all this thing beside I don't overclock anything .
Thanks in Advance !

Then I'll turn it off , cuz anyhow I feel my PC went bad after enabled that , but I asked here to be sure if it is usefull anyway , then your reply changed my mind

Is Cool 'n Quiet stable?
