I am trying to set up SLI on my system, but every time I enable SLI in the nvidia control panel my screen flashes a few times followed by a message to say that the display driver has crashed then a BSOD

Drivers I have tried so far

162.22
163.67
163.69

Ideas anybody?

I dont know if its a problem isolated to the geforce 7950gx2 but i had the same issue and it was due to my card not liking 4gb of ram. I took 1 out and tried and it worked flawlessly. You might want to give that a try and see if it helps before troubleshooting forever

The issue only came about when trying to switch to multi-gpu from multi-display. it worked fine on multi-display.

EDIT:
Damn nice specs BTW

I dont play games so i'm realy not that bothered about SLI enough to lose 1gig of ram

Tried getting the newest drivers? I don't think that it should matter that much if your not into games. Sell one on ebay or something. My friend has a 8600GT and runs all settings on high for his games (this is overclocked). You should be fine with one. Maybe try calling them up though.

I have got to have two cards due to running 3 tft's on it, I just wanted to try the SLI thing, its not like it was going to get and use other than running a few benchmarks lol

If your not having any problems, then leave well alone.
