I have recently upgraded to a EVGA GTX 580 from SLI'd GTX 260's and use one of the 260's for dedicated physics.
The issue I am having is when I go to play ARMA 2, ARMA 2 Combined Operations; my game crashes to desktop but can't figure out how to fix this. But when I play other games it don't crash! I am thinking the issue might be with the one GTX 260 (DX9 Card) running physics for a (DX11 Card) could this be the issue or if not please help me here!
I have re-formatted my HDD and done a fresh install of Windows 7!
I do not have the SLI bridge connected do I also have to have this connected?
To tell the truth I live in UTAH and my friend in California is having these problems and I personally don't think the OC is the issue cause I have my i7 950 oc'd to 3.8 and I can run the same game fine so I am thinking its an issue with the graphics card drivers or software but can't really tell unless I am actually there to look at it.
He has just upgraded from the 260 because of constant crashing in Arma 2 using the 260 and we think we may have solved the issue...system ram had different timings for each stick. Now with that corrected its seems to be running fine.
