I had same issue. My system would just power off... blam... just liken that. I ran Prime95 12+ hours, OCCT, Heaven, 3DMark11, LinX for 50 cycles, and they would all pass. CoD4 - MW, Crysis 2, Metro 2033, etc., all set on the highest settings and never a crash or probelm, even after hours of play. My i7 2600k is OC'd to 5GHz and my ASUS GTX 570 Direct CU II is insanely OC'd at 1003/2200 and never even a flicker... If I played BFBC2 I couldn't even get thru the 1940's intro sequence... everything else played fine... I was convinced it was the game since everything else worked fine... but before I tried gettuing a refund which now days is almost impossible on software, I decided to reset everything to factory stock settings and see if the game played... it did... and for hours on end... hmm... then I gradually upped the OC'ing until the game started to crash again. Damn if it wasn't the OC'ing after all...
: On my system, for whatever reason, BFBC2 is doing something that is so unique that if I go over 971/1150 on my GTX570 it reboots... (and that is exactly 971MHz... at 972MHz on the GTX 570 boom reboot, the problem on the CPU is I needed 1.5v for it to run BFBC2 at 5GHz and that resulted in Prime95 score into the mid-80's so that's out... As far as the game goes it's not temps... during play it never got over the low 50's on CPU or GPU even at 1.5v on the CPU. I just can't run it there 24/7 and sleep nights. I can get 4.8GHz at ~1.38 & 5GHz at 1.415 and everything except BFBC2 is stable. I have a really good PSU (see my rig setup below) so I don't think it's power. All I can speculate is there's something odd/unique (you choose) in the coding that's hypersensitive to video clocks and causes a kernal panic reboot... that's just a SWAG but bottom line in my case it was definitely
the OC'ing and not the game...
So for now I just have it set to 4.8GHz at 1.38v and the GTX 570 is 971/1150. I'm getting ~P7100's at 4.8/971/2150 and ~P7250's at 5.0/1003/2200 on 3DMark11 (275.27 driver) so that's smoking good numbers either way and it's really not all that much different between the two for all the hassle and risk and higher VCore... I'm happy at 4.8/971/2150
One other good thing that happened during alll this "fiddlin" is I was able to get my 8GB Corsair Dominator (2x4GB) from 8-8-8-24-2T @ 1333MHz up to 7-8-7-22-1T @ 1866MHz
: One last note... personally I think in my case the problem was an unstable OC on the GTX 570 since I could get BFBC2 to run at 5GHz at 1.5v on the CPU but no matter what I do, I even edited the GTX 570 BIOS so I go up to 1.2v
and BFBC2 still crashed at that maximum voltage. Not empirical but certainly a bit above anecdotal evidence... Edited by baj2k - 5/25/11 at 3:23pm
