Hi! I can run 13 h orthos small ffts but the blend seems to fail in 50 min. I also got Bsod saying Driver irql less or equal when I tryed to play a game. Next I tried to play it no problems. Oblivion also gave me one error. The windows hd defragment freezen when I try to dedrag. The defragment problem occurs both stock and oc'ed with different bioses(f7,f8i). Could the ram be the issue even though it's running at stock with recommered 2.1? I tried memtest with stock setting two weeks ago and it got 1 pass(didn't have any time to wait longer). I'm going to test with memtest and post the results. There has been some bad geil around. Any ideas? My system is in the signature.
 
i had a set of bad g.skill, wouldn't run at 760 at 5-5-5-15 when its supposed to be 800 4-4-4-14 or w/e it was i forgot.


got a new set from RMA and it can run at 850 5-5-5-15 and its still climbing.



i would run memtest in DOS not windows for a good few loops. if that passes, it could be a bad windows installation.
 
I ran memtest for 11 hours and 25 minutes with the overclocked settings above memory still at stock 800mhz 4,4,4,12 with 2.1 vdimm. I got one error saying something like this:
Tst Pass Failing address Good Bad Err-Bits Count
6 28 000787687cc-1977,5mb f7ffffff f5ffffff 02000000 1
So is the ram bad or does it affect that the cpu is overclocked?
 
The cpu was the problem. Strange that first it can do orthos for 12 hours then only couple of minutes or so with exactly same settings. I have to go with 8x400 with 1.25v. Shoul be enough for games.
