I just can't get my 4670k over 4Ghz with 1.25v. I'm new to overclocking, so I guess I'm missing something (or was it just bad luck with the cpu?)
This is the mainboard I use: http://www.xbitlabs.com/articles/mainboards/display/gigabyte-ga-z87x-d3h.html
You can see all the possible settings. When I start prime with 4,3 Ghz the whole computer freezes after 1 test, followed by a bsod after some time. Same with 4,2 and 4,1 (except it freezes later).
Can someone guide me through this? I'm not even sure if 4Ghz is stable, though it lasted 20 tests, and I don't want to waste time with it now if I'm doing something wrong.
