Okay so I'm having some issues with my SLI setup. I have two KFA2 GTX 770 LTD OC set up in SLI and in some games I'm having some pretty severe issues. It seems that after a while in gaming I start to get some huge visual slowdown spikes, they also seem to affect the CPU, forcing the CPU to spike to 100% usage. This only fixes itself if and when the nvidia driver crashes and I can then use the computer normally. Otherwise I have to reset to do anything.
I've tried using both cards individually and both seem to run fine, I've tried reducing graphical settings in games and that doesn't seem to make a difference. I've even used one as a dedicated physx card with no problems.
The problem I'm sure is a bad SLI connection, I have seen that when the two cards are connected on one side with an SLI bridge the image stutters in game and everything has a weird green and purple hue to it. The other side of the SLI connectors seems to run fine but I still get the slowdown and CPU usage spikes. I've tried a few different SLI bridges and none seem to fix it.
So my question is how can I determine which card is the faulty one? And if it is just a bad SLI connection that's causing my issues? Both cards are from Overclockers and the oldest one was bought in September, the newest in January so I think I can still RMA them if need be.
