So I have an EVGA GTX 970 along with an asus 970 Strix card. both cards function by themselves, however they will not work in SLI. GPUZ and the Nvidia control panel will show both cards, but the option to enable SLI is greyed out and I get a message / alert stating to use the ribbon to ensure SLI is working. I tried 3 different SLI bridges and no go so that wasn't the problem. I googled the issue and to my surprise found that SLI will not work natively when using 2 different brands of GPU's.....why is this a thing? Is this Nvidia being difficult, or does the blame get placed squarely on EVGA, Asus, etc?
