Hello, i recently added a second nvidia GTX 460 to my system, enabled SLi, and i get graphical glitches in games now, and i dont think i even got a performance boost! have tried reinstalling drivers, and even reinstalling the cards!
in games there are white flashing patches on the screen, or flashing grey squares which are slightly see through.
temps are not too bad, never peaking over 60
i have an I7950
6gb of 1600mhz triple channel RAM
and a corsair HX850w psu.
any help would be appreciated, thanks.

What are the voltages on the 12v rail? How much are the changes on the 12v rail during normal use. If it drops to low or has large changes over a short period of time can make the machines unstable. Are you sure the whole card is cool and not just the core? It doesn't matter much if the core is 60c while the power vrm is roasting at 100c. Overheated vram can cause many visual errors as well.

i dont believe it is much to do with heat, if i disable SLi, i have no problems at all. (unless with SLi, temps are much hotter?)the 12v rail doesent seem to change to rapidly, it seems to peak at 4.1v during games, and while not doing any demanding applications, seems to remain under a volt.
If that is your 12v rail then it is way under spec the 12v rail should always be around 12v. Use HWmonitor to monitor the 12v rail.

Don't have the 460, but I did have some flaky SLI problems originally. My problems were entirely isolated to the network driver, and the bridge between cards, It took some time to iron both problems out. Considering the cards worked perfectly individually. Literally the entire fix was the updated network driver for program problems and wiggle the bridge to get better contact for graphics glitches.
