I've just gotten my CPU temperature stable, and thus have decided to push my 2.4 GHz Core 2 Quad Q6600 a little bit. Right now I'm OC'ed at 3.05 GHz with a 40º C idle temp. I experimented with bumping it to both 3.15 GHz and 3.2 GHz; in Windows it is fine, and the temperature stays (about) the same. In OS X, I get something like this (KP):
Machine check at 0x[somehexnumber] 0x[anotherhexnumber] 0x[yetanotherhexnumber]and then of course the address locations.
I have fixed my DSDT to allow usage of AppleIntelCPUPowerManagement (via HPET and LPC patches); I don't see AICPUPM listed in the backtrace, but could that cause problems? Do you have any other suggestions?
I'll post a pic when I get the chance.
