Windows 7: Driver crash, nvldmkm Error 4101, 2x GTX670 SLI

Think i finally got it! Run through a 15min Unigine valley session and came out clean with the cards on SLI.

Turns out it must have been the HDMI Sound driver from nvidia. For everyone's knowledge that is installed automatically from windows. I had completely removed the drivers, and turned updates off. On the next boot though windows found display adapters on it's own, practically the barebones drivers - and it seems that during that process it also downloaded the sound drivers as well. While intalling drivers i only installed display drivers + Physx, but later on (as said above) found the sound ones installed too.

I don't know if you mark threads as solved/closed in these forums, but if so, give me a day or two to test them properly, so we can be sure

EDIT: Well.... NOPE. Had another one.

EDIT2: As far as i've seen the 1st card will pass pretty much anything with flying colors, while the 2nd doesn't seen to like them that much.. Some further testing and then if it gets down to that, RMA

Have you followed the guide i linked for installing the Nvidia drivers?

Yes. I spent the rest of the evening testing the cards indvidually, on the motherboard, and while the one would pass every test, the other one (either alone or in sli) kept failing. So unfortunately, RMA it is..

Either way thank you very much guys, for the time you spent here

Okey dokey mate! Hopefully you get a good replacement in return.
when you say you tested the cards individually I take it you try each card in a differant pcie slot aswell as trying a different sli bridge? sli bridges can go bad a fair bit or just don't work to start with. Sorry for more questions i just wouldn't want you to rma a working gpu when it could be a pcie slot or sli bridge. Covering all bases :)

I tried two different sli bridges. The cards were initially in slots 1&3, and the 'bad' card was failing in both, meanwhile the other one would pass every test -game/benchmark- in these solts

Yeah it's looking more and more like a bad card isn't it. Hopefully you can get the rma completed quickly.
Good luck mate

Thanks a lot! They said something about ~10 days, which isnt that bad, as i have another one.. But at 1440p it isn't nearly enough for high end games.. Still. i got 1 left!

No worries mate! You're welcome
Yeah 10 day's isn't too bad and as you say you still have the one card luckilly.
One of the lads in the community i game with just had one of the fan's die on his XFX7970 after about 3 months so rma'd it but the retailer couldn't offer the same card in return. They sent him an MSI Twin FrozR GeForce GTX 770 OC 2Gb instead I said he should have blagged the 4Gb version as it wasn't his fault they couldn't give him what he'd paid for but he just excepted the 2Gb one. Still a good result mind
