Games go crazy with SLI enabled (rapid colors)

post #1 of 32
Thread Starter 
So I'm trying to SLI two unlocked 470s, and when I enter any game the screen begins to rapidly flicker colors.

As soon as I disable SLI though this goes away. I've tried separate PCI-e slots as well as a different SLI bridge with no changes... Should I assume the new card is bad?

Not the bridge, I've tried two.

Not the Bios, or Vbios.

It's every game or program running in full screen mode unless I used drivers from May of last year keeping 3D enabled but hidden at the game/program start.

Read page three for all details!

Have you tried both cards individually? If they work individually then the problem is likely drivers or the rendering mode you are trying to use.

I haven't run the new one on it's own yet. Still need to test it.

Test the cards individually. If it still keeps happening uninstall driver and roll back to an older (or newer beta) version.

tested on it's own and it's fine... It's at the latest driver too with a fresh install...

latest drivers aren't good for SLI/BlackOps, am having big problem with BlackOps and SLI the display driver "nvlddmkm" stops working and recovers ONLY in BlackOps.. you can try one of the modded quadro drivers 266.77.

This is literally every single game no matter what it is. Even if it can normally support SLI. But what's weird is it doesnt happen when I run Kombustor.

This is an odd problem indeed. Did you happen to test the cards in SLI before you unlocked them?

I suppose it could be an issue with the unlock.

Can you post a screenshot of GPU-Z for each card?

Nope. I highly suspect it is due to the fact that both cards are using conflicting BIOS versions. Explains why the cards are working well when they are not SLI'd.

I don't think MSI AB stresses the second GPU, so that may explain why AB is not affected either.
