I have an x870 Tomahawk with a 9800X3D and a 5090FE.
I have been troubleshooting with NVIDIA for 2 weeks but am starting to think that it may be a motherboard issue. When the computer boots the the 5090 FE only occasionally boots at full PCIE 5.0. Most often it boots stuck in 1.1-2.0 and the system is extremely unstable and eventually restarts itself. I noticed in GPU Z that on the bad boots, the PCIE bus interface monitor never goes above 2.0, and is usually stuck at 1.1. On a good boot, this will hit 5.0 whenever there is a load. Seems like its getting stuck at a low PCIE bus? This is also reflected in HWINFO when looking at PCIE link speed, doesn't go to 32 gt on a bad boot, does on good boot. I rarely get 2 good boots in a row, but can sometimes get 3-5 bad boots in a row. I've updated my motherboard bios to the most recent bios, windows all up to date, all drivers up to date. When I swapped my 5090 FE back to my 4090 FE, all the problems went away. I've tried every BIOS with 9800x3d compatibility and they all do it, however, the most recent bios seems to do it the most.
I've tried locking to gen 4.0, disabling aspm, DDU, fresh windows install, nothing seems to work.
There is a thread here where many people are experiencing the same issues, most of which are running MSI motherboards. https://www.nvidia.com/en-us/geforc...-stutterfreeze-at-win-startup-leading-to-bla/
Anybody have any advice? I am starting to consider buying a new motherboard, even though its only a few months old.
Thanks!
