Help with 7900GT SLI

post #1 of 12
Thread Starter 
Ok I finally got around to putting my 2 EVGA 7900GT in SLI, I thought I knew the steps, but Im clearly missing something, I have a modified DFI UT to SLI (recognized at startup), the SLI bridge is installed, the jumpers changed to SLI, I installed Z-tweaked 91.28, but no SLI in Benchmarks. Am I suppose to change something in the Nvidia CP or the Bios? FYI: One of my 7900GT are is voltmodded

I dont see that option, when I was installing the drivers, the screen went completely blank for some reason, I hit the restart button, and everything seemed installed at startup.
