So, I have two evga 670 gpu. They were fine and all until a month ago, when my display driver kept on crashing at least once a day. Now, it doesn't say that as frequent, but my computer keeps on freezing at least 2-3 times a day. When I watch videos, I've noticed most of voices are out of sync. In addition, my computer feels a bit slow when it is starting up. After I restart my computer a few times, it gets better. I uninstall the driver and download the latest one again. But, it still kept on crashing, so I am currently using the older version of the display driver.

  5. Does each card separately work without crashing?
  6. I'm not sure, haven't tried using a gpu individually cause I use a sli bridge to connects both my gpus. Not sure if I can tell from my monitors, but I have a monitor for each gpu and its usually one or the other that goes black. Sometimes both will go black, and resumes, saying nvidia driver has stop responding... etc. I've searched for this problem and they suggested me to delete and reinstall the drivers again. Which didn't work.
  7. Also, is it weird if only one of my gpu gets hot when I play games. I download a gpu core thing and whenever I play games, it shows only one of my gpu gets hot. I thought the sli bridge should use both the gpus.
  8. Okay. Now take out one GPU out of your PC. Check if it happens, use it for a day. If it doesn't crash, do the same, just to the other card. Report back your findings.
  9. Do I need to change the settings in the bios? or anything? Also, can you check my latest post.
  10. +1 Sunius

    probably have to rma overheating card
  11. When SLI is enabled, I thought both monitors needed to be connected to the top card. Maybe that is what's causing you issues and crashing the graphics driver. I would do what Sunius suggested and test each card alone to make sure they both function properly first. If you didn't change settings in BIOS to enable SLI, then you shouldn't need to change settings when you use only one card.
  12. No settings should be changed. Also, it's normal one GPU gets hotter: hot air rises to the top, so the top card will most probably be hotter.
