New toy ! Fixed ! (PCIE V4 required)

[gsrcrxsi]

Edir: The problem was that the motherboard was NOT PCIE V4. It works in a 7950x board.

not exactly, the board doesnt *need* gen4. you just need to explicitly set the lane speed to GEN3 in the EPYCD8 BIOS when using the Rome CPU.

if you had a Naples CPU, you wouldnt have had this problem.

probably not the issue here. the system it's running on (single EPYC 7542) is only a 32c/64t part.

maybe some kind of motherboard problem or maybe even a GPU problem (assuming he didnt already test it in a known working system) mark should check the logs for pcie errors or other errors related to loading the nvidia drivers. there's not really any trivial reason that the titan V would show up while the 4090 doesnt in this case.

Probably not... But I found it interesting none the less.

I like this thread as it takes us all back to around 2000 ... Linux does that also... So far back, like tasty back bacon!!!! Love the back bacon
