[coop]

I can't believe how well and solid this board is. With Crucial B-Stix 8500's and KHX 8500. Both ran very good on my older P5K-e but required about 2.3 or so to do the same. I think that speaks to the quality and design of these later products. That goes for proc. as well. Crap, with DI even not too long ago clocks like these were only "possible" let alone the norm. I included bios info. I too had an issue with Prime ending. I upped vcore a notch, same time out. Obviously that was not it. Lowered it back and bumped vdimm up a notch. Same thing. Then I remembered reading someone's post about lowering MCH. Tried that and it has ran as long as I can stay up. (2:00am - got to get up @ 5:30) Lowered MCH ref. as well. Maybe it will help others as well. I'll say it, as some may be thinking it. This takes some time and experimentation. Enjoy.
