After 6 months of Profile 1 usage (3D rendering) with 100% load max temps 73C, I have been getting random BSOD (codes 101 and 124).
Same problem with Profile 2.
Someone suggested simply dropping my multiplier to x43 4.3GHz- although changed succesfully in the BIOS, CPU-Z and RealTempGT still report 4.5GHz!!?? How is this possible? Obviously, still getting BSOD.
Profile 3 appears to be the standard BIOS 'optimized defaults' and so far, no BSOD.
I do wish to try somewhere around 4.2 - 4.3GHz but it seems the BIOS is locked to the manufacturers profiles or something... I am having trouble finding a repair shop that has knowledge of OC'ing, so any clues here would really help.
