SLI Not Working Properly

Go to solution Solved by Senzelian,

I have 2 660 Ti GPUs in SLI. When I play demanding games such as GTA V, one card goes above 90% usage while the other stays at 15% or below. I have no idea why this is the case and I often lag.

Have you checked if SLI is actually enabled in your NVidia Control Panel?

Have you tried to swap the cards around or run the card that doesn't work properly in a single card configuration just to see if it works at all?

There is no such thing as excess in hardware.

What was wrong?

When I updated to Windows 10, it automatically reset my SLI to not enabled.

 

How did you fix it?
