I just used a preset overclock in the motherboard bios.
According to CPU-Z it’s at 1.45V when running this sim. It is water cooled, runs at about 55-65 C when in sim.
it’s not running constantly at 4.4GHz on all cores it jumps up to that from about 3.6 as required.
It was the performance setting in the bios. Isn’t it just excessive heat that causes the reduced life, as long as my water cooling is keeping it in range it should be ok?
