PC Peripherals AMD Cool n Quiet = CPU performance down?

SpitefulPentium · Apr 19, 2005

Its a Nice feature to have for hot climates...
When I enable it the CPU temps are really low and its quiet too. no issues here.

The problem is, when this feature is enabled, framerates go down in games. I have noted this in almost all the games. and there is stuttering.

Does the feature reduce the overall performance of the CPU jsut to get the CPU temps down? The cool n quiet software (one with a green cpu-meter) shows the CPU running at 1100MHz. :S no matter how many windows I load or tasks I run it does not go beyond this. theoretically it should have fluctuated depending on the load. but it doesn't. why?

I have enabled the CnQ feature in BIOS and installed the software in XP.

Rig:
AMD 64 3200 NC
ASUS K8NE-dlx
512 Mb TA
etc etc

CnQ feature varies the multiplier accordingly to manipulate the clock speeds as per load and thus lower the heat dissipation. But u probably knew that..

perhaps its not switching speeds fast enough in games? may be u cud try gaming with CnQ disabled.

Disable it when playing games. Sometimes it doesnt switch to full speed when a game is started. I've noticed it when running ut2k4. Just change from minimal power management to anything else in power settings and it'll switch to full speed.

Well thats what CnQ is about.

You have to suffer somewhere if you want to keep your processor cool

you cant get high fps with low temp unless u r using some good cooling solution.

You cant hit 2 things with stone.

CnQ just reduces the multiplier to 4 or 5 based upon CPU from the default multiplier (9-13) when there is no load on the CPU. Thats all it does. Thats why the A64 chips are unlocked down. else CnQ won't work

Hmm, actually I dont mind CPU temps in the range of 50-55 during gaming. thats why I have disabled the feature in BIOS. But the definition says that whenever the cPU load is less the temps/noise will be reduced, BUT it will be normal when there is load, which is not happening.

@Chaos, thanks. will try the power managment thing.

EDIT: do I need to keep the AI OC in the BIOS to standard or something. right now it is manual. and running at a small OC @ 2.3 GHz

same with AXP-Mobile.. how i wish those had been available here

If you changed the multiplier from default, then CnQ might make ur system unstable.

cowax · Apr 20, 2005

hmm i had the same problem,..so does that mean, i have to everytime disable it from the bios when i'm gaming ??
that wud be frustrating.

Aces170 · Apr 20, 2005

Disable CNQ, is a very unstable technology will crash the cheaper PSU's within 2 months happened Thrice with me 2 PSU's dead...

cowax · Apr 20, 2005

:O
i just enabled the CnQ thinking i'll save on a lilttle energy.
neways thaks for letting me know.... *goes to bios and disables CnQ*

archish · Apr 20, 2005

using CnQ on my system for 4 months and till now no performance loss or problems encountered. I am actually happy with it as it reduces lot of fan noise when my dad is working in word.

Well if you are overclocking then you must disable the C&Q. Enable it only if you are runnuing the processor at stock speeds.
Yes sometimes it dosent work properly. Maybe a software update is needed.
I havent tried it personally as i havent ran my CPU at stock speeds at all. But I do know that the first thing you do while overclocking is to disable cool n quiet.

Sure abt this coz i have OCed my 3000+ 2.0 to 2.3ghz with CnQ enabled. No problems so far. Working flawless

Shripad · Apr 20, 2005

If its working for you then good. But its recommanded that it should be off when overclocking. Specially in the case where you touch your CPU multiplier for overclocking.

i kinda doubt this...cuz as far as i know for OCing u need to disable C.Q to get more options in the bios for OCing....or maybe it differs from mb to mb. I got a asus K8N and i have to disable it inorder to OC.

---funkymonkey is right !

I am on ASUS K8V-X m/b and if i disable CnQ i can change the multiplier and the vcore. But since i am using the stock vcore and OCing by FSB i didnt turn off CnQ but if I can go for higher fsb then I should turn off CnQ :no:

Chaos · Apr 21, 2005

K8V-X won't do more than 220 FSB anyway without causing BSODs. Even lower with SCSI drives. Its a crap chipset for oc'ing as it doesn't have PCI/AGP locks.

Doing 231 at 9:10 memory divider. Tweaking the memory timings at the moment. Will post the final results once its done

SpitefulPentium · Apr 21, 2005

well, I didn't change the multiplier. changed the fsb to 210. also at the moment the CnQ feature is disabled, as I'm heavily into gaming for the past few days.
