I get crashes, sometimes it hangs or has driver stopped responding errors. The errors happen as soon as it loads a game with in a few seconds. In 3dmark06 it will hang before it loads the first test most of the time. I have got it to run 1 time in sli mode and the score was about 15K, I can live with that if it would just run all the time and games would work. I have tries several games like farcry , crysis, COD4, UT2004, Black Hawk Down. All run fine with single card. I wanted sli so I could upgrade to a 24' monitor and not lag at high res. Or at least make crysis a little smoother at 1680 x 1050.

I had already change out Memory, I had Super Talent, thought that was the problem, did not help.
I had 2x evga 8800 gts g80 640 that I had bought used each of them worked fine solo as well.
I had a cheifmax 650w power supply but was told it was crap so i upgraded it to.
I had the stock cpu cooler and upgraded that. Cpu MUCH cooler but still same problems.
All of these changes made 0 difference. The Memory upgrade speed some stuff up. but sli still crashed.
Going to garbage can this peice of crap and buy a PS3 or Xbox. Hardware will be the death of pc gaming not piracy.
