I recently bought myself a new CPU (phenom II X4 965 BE) and when playing games it likes to under clock itself to 800 MHz randomly for a few seconds which causes me to get 5fps for a while. I've searched quite a lot about possible causes to this and I've followed a few solutions to no avail. These "solutions" were to disabled all motherboard cpu features, disable AMD cool and quiet and update my motherboard BIOS. Also to change the windows power settings to high performance. I have tried all of these methods and this is still happening to me. I have nowhere else to turn. Does anyone have any idea why this might be happening?
