Its funny that i am having quite the opposite problems. Maybe it is just the P8P67 that is wrought with problems but i am looking to make the switch from the UD7 to the M4E when i can. I have horrible stability issues with the UD7 when i try and OC anything above the Easy tune 6 that comes with a preset OCs of 3.6,3.8, and 4.1. For a while i was running 4.6 on stock voltages just super fine for about 2 weeks or more then whenever i would have to restart pc i would get thrown into a reboot cycle where i would end up having to flash back up to the bios i was using, re-enter my bios info, and try and save, even saving the stats in bios was a haggle, i would sometimes get stuck back in the reboots trying to save stats.
I just stopped OCing for about a few days because i was so frustrated. After doing some research i saw that i was having most of my problems from the dual bios set up gigabyte is running on its boards, i flashed both BIOS to the latest f8x and haven't had a single bios corruption check-sum error since, thought i was in the clear.
At this point i was reinvigorated and decided to shoot for the 5ghz OC, much to my surprise i passed a 1 hour blend test and submitted for the 5ghz club, i was VERY happy and thought my problems were remedied with the dual bios fix. I was wrong, after heading out for a bit i came home and much to my horror, there sitting on the screen was the all too familiar , your computer has failed to boot due to overclocking or voltage changes, the weird thing was i left my computer on and running just perfect before i left, i had even been gaming on and off all day at 5.0 ; even ran some benches totally fine with no problems.
So in conclusion to this mess i decided to just run the easy tune6 4.1 OC untill i can get my hands on a new board, these settings seem to be the most stable where i can not be scared of some random reboot or error that shouldn't even be happening according to being stable in numerous benches.
Ultimately my plan is to get a refund for this board, when the revisions come out and toss in a revised M4E. SUCH a headache with this UD7!!! Sorry for the novel but i know this will help people, since especially i have seen other people having very similar if not the exact same problems not only with my UD7 but also the UD4.
