AMD Athlon 64 3500 Reporting 990 MHz

[nikoli]

Just did a BIOS update on my MSI K8T NEO FIR. Now XP is reporting a 990
MHz clockspeed. The MSI WMI utility tells me this much...

Name : AMD Athlon(tm) 64 Processor 3500+
Max ClockSpeed : 2200 MHz
Current ClockSpeed : 990 MHz
External Clock : 200 MHz
Upgrade Method : undefined
L2 Cache Size : 512 Kb
Display Availability : Running/Full Power
PowerManagement Supported : false
Status : OK

So at least it knows it can be 2.2 GHz. It was working fine before. Is
there a setting in the BIOS that may have changed to slow the
clockspeed? I didn't change anything other than enabling the cool &
quiet feature. That certainly shouldn't slow the clockspeed.

You've answered your own question here- Cool'n'Quiet most definately
does slow the clock speed if the system is mainly idle- see www.amd.com
