Nvidia GPU downgraded to PCIe Gen1 speed on ALTRAD8UD-1L2T

You have no problems. Looks like PCIe has bugs.

PCIe BAR Allocation Error: “bridge window ... can’t assign; no space” when installing 2× RTX A3000 on ALTRAD8UD-1L2

Problem solved! It really was a game of ‘lucky slot puzzle’ lol. I realized that slots 4 and 5 are the x16 ones. I previously had the cards in slots 6 and 7, which was why they weren’t being detected. Swapped them to 4 and 5, and everything is working perfectly now. Thanks for the advices guys. [image] [image]
