Reviving an old thread... I have this motherboard and cpu combo (tp67b+ and i5 2500k)... My problem is that when I bump up the multiplier/cpu ratio, it always reverts back to the original default 33 setting. I've tried settings from this youtube guide...
and also settings from this thread which seems to have a lot of useful info.
The only setting that really seems to stick when rebooting is the vcore.
So then I tried bumping up just from 33 to 34 (instead of aggressively trying for 45 or more). This also made it revert back to 33. Of course, I save the changes in the bios before rebooting. It boots normally, but when I check bios settings, always back to 33. Overclocking guru's, any ideas what the problem could be? My temperatures are low, never above 40 degrees). Seems that most get close to 4.5GHz. Bad chip? motherboard? need more watts in power supply? I admit that I'm pretty clueless about overclocking, any possible basic help on what to try first appreciated.
