Only one GPU folding at a time

[tizzle06]

Hello!

I've been folding with 2 GPUs for awhile now (GeForce 1060 6GB and GeForce 660). However, the computer started glitching so I did a factory reset. Now when I try to have both folding at one time, one of the graphics card slots says "disabled". I took the 1060 out and the 660 worked fine by itself, then put the 1060 back in and removed the 660 and that also worked fine by itself. I am on Windows 10. I was wondering what the solution to this would be? I've tried installing relevant graphics drivers from NVIDIAS website for both, as well as downloading the GeForce experience and letting that auto download the drivers. The device manager on the 660 says "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31) The I/O device is configured incorrectly or the configuration parameters to the driver are incorrect." However, the device manager says everything is working properly for the 1060.

Thanks!

The GTX 660 is a decade old and no longer supported by Nvidia.

This is the latest driver that supports the 660

Yeah it still works when only the 660 is plugged in and folding. But when they are both plugged in, only the 1060 folds and the 660 says it’s disabled

The main problem here is that GTX 660 isn't supported by latest drivers ... so if you want to continue using both, you'll have to stick with the latest drivers that supports both GPUs ...

You could give us more clues by posting the configuration portion of your log, usually in the first 200 lines.

I was actually able to figure it out. I uninstalled the 1060 and 660 drivers as well the GeForce experience and reinstalled the individual drivers manually and that worked.
Thanks for the suggestions!
