Oh, then i understand, knew that, except the part of it going slower and faster, normally it's the other way around.
But the thing is, i have reset everything when i started the thread, and overclocked from the beginning, so i don't really compare it to my old overclock,
and i got it stable with pretty much all tests.
I got a crash on Prime95 Large FFT after 6 hours or something, so i upped the vcore one last time, then it passed 12 hours, then i ran AIDA64 just in case, and it passes overnight as well.
And that was, well perhaps 2 weeks ago, and now i got this crash, i can't really believe it's the age from that short amount of time.
And the thing is that i don't know hot to reproduce it, if i can do that, it's easy to solve, just try different things until the reproducing fails, something like that.
Thanks appreciate the help!
