Cool n Quiet. Off or On when gaming?

Is there a marked difference? I play a lot of today's games like, CoD4, Bioshock,etc. and i don't exactly know what effects it has, if any? I don't want to enable it yet without getting a general feedback from other gamers. Thanks!

Thanks for the link but if you read closely, it doesn't sound very encouraging for gamers.
"Those among us who do not spend hours upon hours playing intensive games or rendering amazing 3D worlds, but do spend time writing with a word processor, sending email, and surfing the Web, own CPUs that spend much time at idle, doing little more than consuming electricity and producing heat. Most of the software we use simply fails to keep the processor busy. In the best of both worlds, we would own systems that scale back when practical, but remain capable of maxing out when necessary. This is where AMD Cool'n'Quiet™ technology comes in."

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

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 and core centre question

just a quick question
if i dont have cool and quiet enabled in the bios and i start core centre it reports my Mhz as 2400 ( i have the XP 64 3700 chip )
but if i enable cool n quiet in the bios and then start core center it reporst the MHz as 1000
and i was just curious why ........ faintly paranoid that my chip isnt running to spec
thanks if you can help and no probs if you cant

so with cool and quiet enabled my chip is running at half its rated spec 1000mhz instead of 2400mhz
would this be why DOOM detected my pc and set all detail to low even though i have an x800 xp 64 3700 and a gig of ram .... DOOM basically underspecced my processor
thats a bit mad as father dougal would say
ok last question ... with cool and quiet off the processor is reporting at 45 degrees so i would imagine under load ( saY a game of doom 3 ) it would hit 50+ .... whats the max safe temp for these chips 65 degrees ???

MSI K8T Neo2-FIR - Cool'n'Quiet FIX

Just turn Cool'n'Quiet off in the BIOS...that's what I did and it works now.
Doesn't make sense...but oh well.
Gman22

@Gman - I see now, what you meant. Another workaround: Speedfan.
@Bas: Gman referred to the bug in Core Center, where fan speed can't be controlled if CnQ is enabled.
Yes, I know that CnQ is something else than fan control.
Fan (the hardware way) control on K8T Neo2-F(IR) is fixed and can not be set by user. Actually CPU fan speed will normally be 2/3. I think that CFAN will rise to 100% if a certain temperature is reached. Although SFAN could be regulated, too, MSI apparently decided to let this on 100% speed.
So, if user wants other fan speeds, he has to rely on additional software.
Core Center is not suitable because of a bug that prevents the software from controlling fans if CnQ is enabled. On the other hand, CC doesn't seem to be designed for Windows NT 5.x, where different types of users that have different permissions are established since 1999 (Release of W2k)

Crackling! When AMD Cool'n'Quiet is enab

I was wondering why that is, recently because summer, I have enabled AMD Cool'n'Quiet option, when I switch it on, the X-Fi (Elite Pro) begins to crackle. I turn it off, it becomes flawless once again.
I'm on nForce 4 chipset (A8N32-SLI)

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.

Cool 'n Quiet and Gaming?

I installed the required AMD Processor driver and set the XP power setting to minimal power usage and Cool 'n Quiet immediately kicked in after a reboot. My CPU now runs at a steady 1000MHz and about 5-7C cooler
Is there any way to configure this such that it doesn't kick in until after a certain period of low CPU activity? While playing FarCry I noticed quite a bit of sluggishness and lag with this enabled. It seems that Cool 'n Quiet works TOO well because the CPU actually bogs down while it should be mostly pinned at 2GHz
It's easy to fix by putting the power setting back to Desktop where the CPU always runs at 2GHz but I like the idea of giving the CPU a breather and cool-down when I walk away from the machine and am only doing P2P sharing or whatever.
Thanks!
John

I play battlefield vietnam. After I installed the driver and started using cool and quiet I noticed a big drop in temps. MHZ drop to 800 at idle. Really quite cool like 38`. Very impressive.
I havn't noticed any degradation in my game play. One thing I have done....just to "check" to see what my cpu was doing while running my game:
During gameplay I can hit ALT-TAB. Then I goto start, control panel, system and see how many mhz my system is cranking. It always shows 2000 for me, as it should while running and intense game. Then i can just click on the bfvietnam bar on the taskbar to jump back into my game where I left off.

Gaming problem with Cool n quiet ?

Hi there,
I've enabled cool'n'quiet in the Bios, because my fan was doing too much noises.
So now in CPU-Z, the multiplier is x5. But the problem is that is STAY at x5 even when i'm playing game like DOOM3 or Half-Life 2.
So it is lagging a lot in the game, but it doesn't crash (thank god).
I wonder why my fan don't ajust itself, because it should right? CPU go 100% but the multiplier and the fan speed stay don't move.
Thanks,
TanGU.

Try enabling cool n'quiet in the bios. I had the same experience when I first built my pc a while ago.
Uh... thanks but, like i said:

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.

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.

785GTM-E45 - Cannot Get Cool N Quiet to work

So ive been in and out of the Overclock (the switches on the motherboard its self) and Cool N Quiet doesnt seem to be throttling the CPU and voltage at all when the computer is idling. Overclocked or stock clocks, it doesnt adjust anything. Im using CPUID to watch the speed and voltages.
Im using Windows XP 64bit with a Athlon II x 4 630. The power options set to "Minimal Power Management"
I also have double checked the bios to make sure it isnt Auto, but instead "enabled"
I tried updating the cool n quiet utility but it says im already up to date. I have already updated the bios as well.
Any suggestions to get this work properly?

All that tree hugging hippy green-earth power saving junk just adds variables to an already complicated and delicate situation in a well OC'd machine. C&Q and related 'wares have never added anything to stability and have often been known to detract from it. Serious overclocking is virtually the opposite of saving power. Why risk stability (or run at lower speeds) to satisfy your need to be green? Just turn the machine off when you aren't using it.
You guys... I really dont care about thread battles. Although I do agree, some people could just simply turn off the rig sometimes but I have an issue thats probably easy to fix. I've had an overclocked E5200 to 3.5ghz before and what ever the heck Intel calls their version of Cool N Quiet; it was working perfectly fine. I also had an 3800x2 that was able to throttle down on a Via chipset motherboard!
So, im just tryin to satisfy my self with overclocking and have Cool N Quiet at the same time. If Asus and Via can do it, I need to figure out why this 785gt isnt doing it properly. :D

Cool and Quiet ok to use on NF980-G65 / 965 CPU?

Hi,
I'm wondering if it's safe to use the cool and quiet option in the bios on the NF980-G65 motherboard with the AMD 965 Black Edition CPU.
I had the MSI overclocking center open (I'm not overclocking just monitoring the temperatures) and heard this faint siren sound, thought it was one of my neighbors car alarms. Once I discovered that it was coming from my computer I opened HWMonitor and noted that the CPU fan was only running at 3%, and I guess that's lower than what ever is configured in the MSI Overclocking center since the alarm noise was coming from the overclocking center.
The CPU was still in the safe zone at about 54°c at the time that the CPU fan was down running at 3%, my guess was due to cool and quiet taking over maybe.
I've read that this CPU can go pretty high in temps but of course we should try to keep it as cool as possible so this leaves me baffled about the cool and quiet (if that's what causes it) to drop the CPU fan down to about 1680RPM since the temps seem like they would have kept rising if the fan doesn't speed up.
Anyway, is it safe to use Cool and Quiet on this mainboard with this CPU?

Unfortunately, I live in a 40+ year old house, in the desert, where our now summer month temps are into the 3 digit marks (100-121°f) and this house doesn't have insulation in the walls so the temps inside are only maintained at 76°f and the computer room is a bit hotter than that even with the central air going and an additional window a/c unit in the computer room.
I am using the Thermaltake Element G box which has a huge fan on the side door, a very large fan on the front, an equally large fan to exhaust on the back, an large fan again on the top of the case and finally, 2 60mm fans on the back to exhaust near the video cards and so my CPU runs probably warmer than the average person that is able to keep their rooms down to 65°f unfortunately.
Anyway, the cool and quiet used to be turned off and I had the other options on so that it would try to maintain the CPU at 45°c which it's perfectly capable of doing when I'm not playing games, and of course it's still capable fo keeping it under 60°c when playing games, and most of the time the temps dont' get above 57°c when playing demanding games but it concerns me that the CPU fan would drop to only 3% using cool and quiet and I'll likely turn it off again but I'm still curious if there is any known issues with running cool and quiet on this mainboard and CPU.
Thanks for the reply

Cool'n Quiet Preventing Restarts

Looked for this issue but didn't find it - sorry if it's a repost....
When I try to restart WinXP with Cool and Quiet enabled, the screen shows "Shutting Down...", my monitor shuts off, then IDE LED stays on for about 20 seconds and goes off but the comp is still powered. From there I can hit the case reset and reboot so this isn't major but really bugs me. When I switch the C'n'Q off (by going to something other than Minimal Power Management) I can reboot fine. My comp shuts down fine in any case.
It's as if my CPU isn't powered enough to go through with the restart. I'm new here and need to post my specs, but for now wanted to know if anyone else experienced this? Thanks.

When I turn the CnQ off in BIOS but keep Min Power Mgt, I can reboot no prob - same thing as if I keep it on in BIOS but switch off Min Power Mgt. Seems like the bottom line is: if CnQ is off - no matter how, just off - I can reboot.
Yes I *think* I did change Min Power Mgt to be 'Turn Off Monitor After 5 minutes' - which I'm not sure if that's default or not. I regularly change it from '1 Minute' to something else, although I'm not sure I changed it with my current install yet. If I did, that would be the only setting I would've changed. 'Turn Off Hard Disks' and 'System Standby' are always both 'Never'.
I have Sp2 - haven't tried this pre-Sp2 but I'm going to re-install this weekend with just Sp1 and see if it happens.
Thanks for the replies. I feel better just knowing I'm not the only one

Cool'n'Quiet hanging??

I enabled Coo 'N Quiet on my machine the other day, nice cool running box now (about 30C and 38C under load). Problem is when I get home from work and try to use it, it doesn't respond. I end up being impatient and powering off/on. The event viewer shows no errors or problems, just an unexpected reboot (my power off). Any ideas? I have turned it off in the Bios again and will see when I get home tonight if it's hung up or not.

Yes, If you're leaving it idle for long hours it would be best using S3 or S1 standby. Since we're using the same Mobo, I can report that S3 standby has been reliable.
If you're not encoding files, running downloads or a wide range of other such activities, it would be a good power saving practice using S3 standby or complete shutdown (inspired by Living in a Country that is currently experiencing a Huge Power Shortage ).
Like to know if it's still non-responsive after shutting down Cool 'N Quiet...since the topic is: Cool'n'Quiet hanging??
