Windows 7: AMD Cool'N'Quiet driver problem

AMD Cool'N'Quiet driver problem

Hi,

This is a system with an AMD Athlon 3500+ and I'd like to enable AMD Cool'N'Quiet CPU power states. (to behave something like Intel's advanced speedstep, which automatically reduces CPU frequency when there isn't high load)


Here's what I tried:

- I updated the BIOS to the latest version.
- There's a BIOS Setting "Enable Cool 'N' Quiet" technology which might be related to this. I enabled it.


It boots up fine but nothing changed. Now the computer is unable to power off if CnQ is enabled.
It just hangs on the "Shutting down" screen (spinner is still spinning, it's not frozen, just hanging). I tried it several times, even left for 10 mins, no effect.


I had to reset the computer. If I disable CnQ, it can shut down correctly.



What should I do?


Here are the system specs:
Motherboard: ASUS M2V (latest BIOS)
RAM: 2 GB DDR2
HDD: 200 GB SATA
GPU: NVIDIA 7600GT
Processor: AMD Athlon 64 3500+


UPDATE:
While on Windows XP this feature works fine by installing the CPU Driver but it does not work on Windows 7!

There is no need to enable cool and quiet if you want to control the fan speed

You might want to look at third party programs

I don't want to control fan speed, I want to control CPU core clock. frequency.


Example: I want it to go down from 2200 Mhz to 700 Mhz when idle. Something that Intel processors do. (I believe this is called "Advanced Speedstep" on Intel CPUs)

This is something usually found in Mobile processor setups. Desktop machines do not have the same Power configurations. You can control several things in the power setting in Windows 7 if you want. I am using a 3400+ with no issues and did not install CnQ or any other control driver for the processor. As others will advise-it is best to let it run as designed for a desktop setup.

You have to go into power management and set to power saver mode for cool n quiet software to work, but that wouldn't have anything to do with stopping the hanging I don't think. I guess win 7 built in throttle control not working with the older workhorse Athlon?

Also, I couldn't tell from your post, you mentioned turning it on in bios, but you also have to have the cool n quiet software installed on computer as well I believe. That is different than cpu driver(which I don't think you need as you stated) Not even sure if AMD has cool n quiet software version for win 7, last time I used it was in XP. Old version might still work, or you could try rmclock which utilizes cool n quiet as well and I think it worked in vista so maybe that's your ticket. Don't forget power saver mode.

I know about the power mode thing (but thanks for reminding me!)

I tried the CnQ software _and_ the driver for it but it didn't seem to do anything.

You're right, it might be a compatibility issue. I'm thinking to temporary revert to XP on this computer as it's very slow with 7 even after optimization (as described in my other thread: Which OS would have the best performance on this computer? )

I have AMD microcode update enabled in BIOS. Should I turn it off? And how about AMD Live? (that one is off and I don't know what that one does)

seriously if you really want it on turn on ce1 c6 then cool and quiet you have to turn on power states for it to do this

Can't just turn on cool and quiet with out CE1 C6 turn those on and QnQ should be fixed if that isn't enough go to AMD.com look your chip up grab the hotfix for windows 7 case closed

How do I turn these on? Are they in the BIOS or do I need 3rd party software to enable these?

Was thinking, due to what you are trying to do, that this might be a voltage problem and Solarstarshine is right on target I think. I also think you would need to enable the C-States to allow the CPU to halt or limit it's power usage: Everything You Need to Know About the CPU C-States Power Saving Modes | Hardware Secrets

Since you have an Athlon 64 3500+ chip, pay attention to the sections on C3.

the C-States are in the BIOS
If you aren't overclocking, there is also an option for power management (maybe - there should be) that will supply the optimal voltages to the components.

If you can, post the bios brand and version and we might be able to guide you through to the setting you will need.

I don't know too much on this so follow up with others first before changing anything and post back some info.

They would be in the Bios under CPU it should be some power settings where you were before

they should be right next to cool and quiet features in the bios should see a C6-CE1 and a few others APM automatic power management I would have to see your bios layout to know for sure
