Very weird problem OCing 955BE

Having a very odd problem here.

I'm trying to OC my cpu (Obviously) and whilst I can change the multiplier in AMD OverDrive very easily (In fact I hit 3.8Ghz stock voltage linpack stable and 4Ghz @ 1.4V - didn't get a chance to go higher before hitting this odd issue).

The problem I'm having is that if I set the multiplier to higher than 18.5x (3.7Ghz) in my bios the CPU gets limited to 2.5Ghz (12.5x multiplier) :shrug: Although everything including OverDrive detects the 'correct' frequency, but the CPU is only running at 2.5Ghz. If I set the multiplier in the bios to 18.5x I can still push it higher using OverDrive without any issue at all.

Here is a screenshot showing the problem (Compare Target Speed to Current Speed in OverDrive):

Could this have something to do with Cool'n'Quiet. Didn't get a chance to try turning it off before having to leave for work this morning.

I am seriously impressed with this chip btw (3.8 stable stock voltage and I can get 3.9 almost stable)

BTW: Specs are in my sig.

Thank you to everybody who didn't answer...

Turned off Cool'n'Quiet and the cpu is running at the correct speeds.

Yeah, I suppose I also should try not to post when I'm tired and cranky :cool:

no problem =)

FYI (even if very late!), usually CnQ is fine until 18.5X but after that simply stops working even if left enabled (but without that bug).
