I got a 2nd GTX 570 to run in SLI. Installed it, ran a benchmark test and my screen starts flashing green and pretty soon everything on my main monitor that the new GPU is plugged into is green. I have to restart to fix it. I was using 301.42 driver, so I stepped back to 295.73...same issue. I reseat the card - same issue. I pull out the 2nd card and run just the new one alone - no problems, but it seems to run about 10% slower then my Zotac 570...not to mention that the voltage is also clocked higher, but the clock speeds are the same as my Zotac. I put the new card in and then my Zotac in 2nd...increased the voltage - same issue, screen goes green. I put my Zotac in the first PCI-E slot now and the new card in the second - no issues. Screen doesn't turn green but I do get a few random crashes from time to time. I also see negative improvement in games in SLI - usually by 10-20% and it doesn't matter what driver I'm using. (yes, I do understand my CPU is holding things back, but it will be a bit before I can upgrade the MB, RAM and CPU) So, does it sound like the new 570 has issues?
