Stop error 0x000009C in Win2003 SP2: Cool'n'quiet (PowerNow) suppo

[Guest Dario]

Hello.

 

I am looking for a solution to using the powermanagment drivers from AMD

with a

dual core opteron on a Win2003 SP2 system. SP2 seems to be the problem?

 

Any know if Microsot has a solution for Win2003 SP1, similar to the fix for

Win2003 SP1, to support AMD PowerNow driver (Cool'n'quiet) for dual core

Opterons?

 

It sure seems like Win2003 SP2 does not support ACPI processor performance

states (effectively no support for AMD PowerNow! in SP2)?

 

The problem occures after a while using the latest AMD PowerNow driver (also

happened in SP2 with previous drivers). The system stop error logged is

0x000009C similar to KB924441.

 

Ref. to support for Win2003 SP1 (KB924441):

http://support.microsoft.com/default.aspx/kb/924441

 

Regards,

David

 

Details of my case:

- BIOS is set for Cool'n'quiet. ACPI 2.0 is activated in BIOS as well (even

though that should not play a role in this case?)

- The system will eventually crash with a stop error if I simply install the

PowerNow drivers for dual core Opterons.

- With PowerNow drivers installed, before Win2003 SP2 crashes, AMD Power

Monitor can however verify that the cores in the CPU are under power

management from the AMD Powernow driver.

- If I uninstall the AMD Powernow driver for the CPU, the stop error stops

occuring.

 

The problem occures after a while. The system stop error logged is 0x000009C

similar to KB924441.
