Last night I was gaming and found a massive performance hitch, I checked CPU-Z and my CPU was running at just x14 multiplier. (1400mhz).

Seemed that I couldn't get it to run consistently at its full or turbo speed like it usually does.

I tried stressing the cpu using LinX , it would jump upto its turbo clock and then back down to 14x again in a split second, it would never stay at its max multiplier.

Temps were fine when I checked, just 30'c load and I never exceed more than 65'c when gaming.

I've had this once or twice now and a restart and things are back to normal, just makes me wonder what's going wrong and which power saving feature is causing this. My bios settings are all at auto/default.
