GTX 570 SLI?

post #1 of 2
Thread Starter 
Anybody but me here doing this? My single 570 was a pretty good overclocker. Now that I've added a second identical card, I can't OC my GPU set-up so that there are any benefits. It really sucks. Does that mean that my new card is a crappy overclocker? Would it help if I swapped the cards' positions? Does it mean I've overtaxed my PSU?

I figured out the problem. When you change voltages in OC Scanner you have to change voltages for BOTH cards. I thought one voltage change was all that was needed. Now I'm afraid that my Antec 750w PSU doesn't have enough juice to reliable supply the voltage needed in my system. It is making quiet rattling sounds when I run a benchmark test for my graphics.
