Hi, I used my old SSD and installed windows 7 on it, so there be no left overs of other drivers, Installed the 320 drivers, restart and installed the modded drivers, restarted and went to nvidia control panel and enable sli, same as before black screen.
Then I went to safe mode to uninstall the drivers, clean the drivers off the system, then moved my 470 to the top slot, and the 480 in the 2nd slot, same as before black screen. Went to safe mode again and went to Device Manager, and windows shows that they have problem same as before with the 314 drivers, with the 314 drivers and the 470 on the top slot, I could get sli on, but when open any game, system locks up and the screen keeps blinking on and off. With the 320 I get nothing???
Could the problem be with the size of the vram, one has 1.5 and other has 1.2? but with the 310 and sli on, gpuz shows both with 1.2gb of vram.
