I read thru all of those and did all of them I cud with exception of CSM support disabled it wouldn’t let me do that I tried all that trying get the 3080 to work the first time so I switched out GPU’s and now back to square one… seems like shud be just one easy setting to switch for them to work together or possibly my motherboard can’t handle those cards interchangeable together on same board…?
It definitely supports multiple GPU’s because the two nvidia cards work together just not amd & nvidia together has that been issue with certain Motherboards…?
