I just bought a new GTX 570 for my PC. My games such as Crysis ,Crysis 2, Metro 2033 etc crash to desktop with my new config. I removed my GTS 250 (dedicated Physx) and even got my 850 watt Coolermaster PSU replaced but nothing seems to work. I have tried the 266.58 and 270.51 drivers, but the games still crash on both the drivers. Could it be that GTX 570 (aka GF110) is incompatible with 790i Ultra SLI Chipset ?
FYI: I installed my GTX 570 on my friend's PC and it worked absolutely fine (in games, transcoding, idle), on 266.58 drivers.
I have an EVGA 790i Ultra SLi and I don't understand why it wouldn't be compatible.
Have you tried installing it in a different slot? Or better yet, have you used Driversweeper to remove ALL of the old drivers before installing the new ones? I would take a gander that it's a driver issue and not a hardware problem.
Ok shouldn't be any problem there unless the voltage is a tad low. I'm running my gtx570 at 900/1800/2000 at 1.1 volts solid, but I had the same problem you did back when I was experimenting with clocks and bumping up voltages. But for your clocks, 1.0v should be fine.
Ok, I increased the voltages to 1.0V but it didn't work. I even tried .913 .925 .938 .950 .963 .975 .988 1.1V as well but nothing seems to work. I'm thinking of reconsidering my GPU stability (problem with the GPU itself) as only upon adding and using the GTX 570 does my system lose its stability. is there any program like memtest to check my GPU ?
ok I think I have figured it out. I rechecked my graphics card on my friends PC and there weren't any problems, I played Crysis 2 for straight 1.5 hours. Then I thought when I first bought the 790i none of the nforce drivers except the 9.64 worked perfectly. So I installed Win XP 32 bit, installed just the 266.85 drivers and voila my games are't crashing anymore. Apparently the chipset drivers that Windows 7 x64 deploys were somehow conflicting with the GTX 570 and not the GTS 250 (as the main card) and was hence showing dual behavior. I am slowing installing other drivers on Windows Xp while creating retore points and post results after playing the above games for an extended period of time.
