Yesterday I got a BSOD while playing DayZ, I think that it might be the second card in my rig overheating. I'll be ordering an aftermarket heatsink for it soon but I was wondering how I could go about stress testing my crossfire setup. In the past I used ATi Tool but the program doesn't use both cards. Is there a program that I can use that will max out both video cards so I can stress test them?
