No, I didn't have any issues ocing in 7. I never went to 8, tried it and didn't like it so I reverted. I disabled all power saving features in the bios. So then with windows 10 and my bios this chip is pretty much gimped. Nice. Well I'll be upgrading here soon anyways but nice to know I will need a new board if I want to oc. I'll upgrade to a newer build of 10 and see if that fixes it.
