cheers mate. well it has some strange behaviour for sure. as M3kk has said when you save an overclock in BIOS it often just powers on and off for less than a second repeatedly. if you hold the power button until its off then leave for 5 mins or so before turning back on it starts no probs with the new overclocked settings. very strange.
didnt have much time to play as on nightshift(bah) but it was BSOD right before entering windows on same settings that were fine with the QX6850. I also tried lowering FSB and raising Vtt to max values due to the huge droop with Yorkie and Vtt on this board but still the same. in the end I only had 5 minutes so just made sure it was stable on stock settings and the mrs informs me Prime is still running fine(6 hours or so) so at least that gives hope that can tweak it a little at a time and get a stable overclock going when i get some time, hopefully tomorrow.
