SLI strangeness.........

Recently I think I've got a problem with my SLI set-up. When running some heavy loads on SLI the screen sometimes comes over with a coloured hue - slightly redish or greenish which will come on and go off as it pleases

Does this sound like the bridge is faulty or my cards are on the way out?

Has anyone else had this happen to them?
 
All of the cabling seems fine which leads me to think it could be the bridge - the cheapest component in the PC at a ground breaking £3 lol.

Afterburner is showing the cards working correctly and benchmarking results are coming out fine (1600ish score on Heaven)

Temps are not exceeding 50 C

I'll double check temps when I get back home but I'm certain that I OC'd it well below dangerous temperature levels
 
How are you measuring those temps? just curious. The main other thing to check then is your video cable connections etc... but it seems unlikely they would be the cause if it only happens under load.

Edit: Just seen the post above. As you say they are OC'd, have you tried putting them back at stock and seeing if the problem disappears?
 
I'll try returning them to stocks tonight and see what happens. I've had the cards as high as 845/1690/2150 but I'd pulled this back to 810/1620/2000 to keep temps reasonable.

I've used Afterburner to keep an eye on the temps. The thing is that the 'hue' doesn't always appear - I could play for two hours on something like the witcher 2 ultra with nothing happening or I could run it for 5 mins and get it happening 10 times. It's never happened just running non-game applications. Very strange......
 
Heavy loads being Crysis 2? or are you not talking games here?

As i sold a GFX once and 2 days later he came back saying it was faulty.. i was like it cant be i was running it fine.. Turns out it was doing this

Which is a DX11 bug i think, Tho im not sure if that was fixed..

This might be totally irreverent but i thought i would mention it!
 
seems like it is just a software bug you have been unlucky enough to find then? If it is a DX11 bug have you tried running in dx9 / dx10 mode where available?
