Hey guys! So I've been running 2 970s in SLI for a few years now with no issues. A couple days ago I swapped cases and put a new PSU in. After that I updated my NVidia drivers. Now when I play games with SLI enabled, I get terrible frame rates. I disable SLI and everything is golden again. I read that the newest nvidia drivers are having issues. So I got rid of them and put drivers on there from Dec. (I had no issues with those). After reading and reading online I can't find a solution and I am stumped. What can I do?

Thanks!

If the newer PSU offers either less power or is of lower quality than can cause problems.

When you updated drivers, did you chose 'custom install' and then 'clean install'. That often helps. If you decide to go back to the old drivers use that option too. There's also NV driver cleanup tools out there(Guru3d has most of 'em on hand). I have 2 970's in my other system but haven't updated recently and they're still running good on 376.53. Might want to try that one. Also make sure your ribbon(s) are properly on along with power connectors to the cards/psu.
