Hi, hope someone is able to help with this. I have a rig using a ASUS PRIME Z-490-A motherboard. Mining has been working great for about two weeks now with the Linux OS. I currently have x3 Nvidia 1080’s attached to the board via risers. Unfortunately, I have encountered a problem when adding a 4th card. The rig refuses to boot with the 4th card plugged into the board. If I then disconnect the 4th card, no problem, the rig fires up as normal. I have checked all the BIOS settings I can think of for this board, and have made the recommended changes for mining. However, the problem persists. I tried switching PCIe lanes multiple times, but this makes no difference either. 3 cards works, 4, or more cards, no go!
Is there anyone out in the community using this board, or another ASUS PRIME board with the same issue? Have you been able to get 4 or more Nvidia cards running? Please share your fix. I would greatly appreciate it!
