Problems with 3090ti paired with second GPU

[Ben Durrant]

I have a 6 monitor setup so I'm trying to use my 3090ti with a second gpu, however I can only get output from one of the two cards - never both. I've tried it with both a 1050 and 3050 but with no joy. I've tried every combination of putting in the cards one-at-a-time, driver re-installs etc but with no luck.

What is odd is that it worked fine with my previous 3090 (both are founders editions) and the cards aren't that different.

If anyone has had success with this then please let me know.

I have the Asus Hero Z690 motherboard with Windows 11. It appears I'm not the the only one having this issue: https://www.nvidia.com/en-us/geforc.../problems-with-3090ti-paired-with-second-gpu/
