Ya I dont think running prime for 12 hours proves jack IMO. When I was trying to test my OC Prime would fail it hours later. However, a senior OCN member told me to forget about prime, and just game and fold. Have not had a problem with it since I have been stable on my OC for ahwile now gaming folding and everything since. I did have a problem a day ago but turns out I got bunk memory from the egg.
Not dogging on prime just saying that its a bit much just to see if you got a stable OC and is unreliable in my case. Folding and gaming 24/7 for weeks with out BSOD is all the stable I need. 4.3GHz @1.26v
