The motherboard is a DP67BG.
The problem I'm having with overclocking, is that when it boots properly, there seems to be no actual effect.
If I set the settings to something unstable, the system fails to boot, as you would expect. However, when the system does boot, testing the cpu yields the same results as it did before making any changes.
The CPU under load performs at 3.39ghz. Change the settings too high, system fails to boot. But changing them to seemingly acceptable levels, and the system doesn't change.
Right now, I have the multipliers for all cores set to 37 (with the default clock of 100mhz), but the system is still performing at the 3.39ghz it started at.
Other than failing to boot when bad settings are given, and failing to boot at all during autotuning, there seem to be no other issues with the system.
It runs at 26c idle, and 45-50c under full load, has never gone over 54c.
This is a SS of the autotune log, it mentions a warning about a system hang, presumably the couple of hours I let it sit there wondering if that was normal.
