WinXP (32-bit) SP2 --> Cool'n'Quiet don't work!

Hi,

I installed the XP SP2 last weekend and I just now noticed that Cool'n'Quiet
doesn't work after the SP2 update. (Noticed because video playback was
jerky...)

I tried to uninstall and reinstall CPU driver... but no help. I checked the
power management settings... and they are set to minimal power management.
It doesn't matter what I set, the CPU is always running at lowest speed.
(Yes, I tried to stress the CPU to see the speed increase... didn't work.)

If I uninstall the Cool'n'Quiet driver, the speed comes back to normal (full
speed).

Prior to SP2, Cool'n'Quiet was working great.

I have ASUS A8V Deluxe and Athlon64 3500+.

Anybody else having the same problem?

Interesting, when I installed SP2 it overwrote the AMD driver with the
default MS driver, I had no CnQ at all, all running full speed (on a base
K8V). Have you tried the latest CPU driver from AMD's site rather than
those supplied by Asus? Re-installing this returned CnQ to normal for me.

At the moment I'm running the latest driver downloaded from AMD (dated
4/25/04, I think...) Still don't work: Stuck on lowest speed setting.

I didn't reinstall the C'n'Q software after that. In my understandind that
software is only for displaying the CPU speed and voltage...

Similar problem here, except it's stuck on the highest speed on my ASUS
K8N-E and A64 3000+. Until it wakes up from suspend, that is--then it's
stuck at 800MHz.

I don't know if it would have worked on SP1 because I installed straight
from a slipstreamed SP2 CD.

Reinstalling the AMD driver didn't seem to have any effect.

Well... couldn't find good solution yet.

As a temporary solution I'm using Clockgen to manipulate the multiplier and
voltage manually... when needed.

Luckily the fan speed control seem to work.
 
Aren't there motherboard drivers you can reinstall?

Just wondering.

Don't think so?

All that is needed is to enable the Cool'n'Quiet and ACPI2.0 in bios, and
then install the AMD CPU driver, and then set the power management options
in windows for minimal power management... At least that's how it worked
before WinXP SP2...

I even flashed my motherboard BIOS to the latest... but no help.
