So the story is that I accidently bought a 2.8ghz laptop cpu in for my desktop. It works fine, but it runs at 1.6ghz. The note on my cpu is that the processor frequency is reduced to 1.6 GHz in battery-optimized mode (1.2V). I tried increasing the voltage to 1.4 on my mobo, but it remains at 1.6ghz (the multiplier in my bios is grayed out at 12x instead of the necessary 21x). Does anyone have any ideas/tricks that I can get it to run at 2.8 ghz?
