when you run the 980 + lan card, which pcie version were those running?

do you have a pcie version setting for the slots in the bios?

It works with the Mellanox in an x1 slot. Not ideal, but at least a temporary solution. I'd still appreciate any insight.]]> Sat, 06 Apr 2024 09:29:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=34372&PID=116720&title=no-boot-with-both-x16-slots-populated#116720 https://forum.asrock.com/forum_posts.asp?TID=34372&PID=116649&title=no-boot-with-both-x16-slots-populated#116649 Author: trggrhppylmbx

Forgot to add, the RTX of course is Gen 4, the Mellanox is Gen 3 PCIe]]> Thu, 04 Apr 2024 11:21:25 +0000 https://forum.asrock.com/forum_posts.asp?TID=34372&PID=116649&title=no-boot-with-both-x16-slots-populated#116649 https://forum.asrock.com/forum_posts.asp?TID=34372&PID=116648&title=no-boot-with-both-x16-slots-populated#116648 Author: trggrhppylmbx

On my x570 Steel Legend with a Ryzen 5950 CPU I have a problem booting with both an MSI 4080 Super and a Mellanox ConnectX-3 in the x16 slots.

With only the MSI card the system boots just fine. When I plug the ConnectX-3 into the other x16 slot the system stops with the VGA LED on. I tried setting the PCIe lanes to 1x8, 2x4, without success. When I pull the Mellanox card the system boots normally. The Mellanox card works by itself with an older graphics card (GTX-980).

Is this a BIOS issue or is there a fundamental problem with the RTX and an x4 card?

Thanks!]]> Thu, 04 Apr 2024 11:20:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=34372&PID=116648&title=no-boot-with-both-x16-slots-populated#116648
