Hey everyone,
I'm having a really frustrating issue with my motherboard after a BIOS update and could use some help troubleshooting.
System specs:
- CPU: Ryzen 9 7900X
- GPU: RTX 3090 Ti
- BIOS: Originally v603, now v3057
Here's what happened:
I bought a new 2TB Crucial Gen4 NVMe drive and decided to install it in the Gen5 slot. Before doing this, I updated my BIOS from v603 to the latest version (v3057). After the update, I noticed my 3090 Ti was only running at PCIe x1 4.0 instead of x16.
I thought it might be a PCIe lane limitation issue, so I reseated one of my old Gen4 NVMes with the new NVMe drive to free up lanes so that there isn't 3 at once. However, the GPU is still stuck at x1 4.0. I've tried:
- Resetting BIOS
- Clearing CMOS
- Downgrading BIOS with no luck so then updated back to v3057
- Tried downgrading BIOS version to original v603 but I get a "Invalid bios file" error
- Updating all drivers and software
- Running the original 2 drives
One interesting thing: In the old BIOS (v603), there was an option to use x16 mode, but this option is completely missing in v3057. I've looked through every BIOS menu and can't find it anywhere.
Has anyone encountered something similar or knows how to fix this? Running this GPU at x1 is definitely not ideal and I'm out of ideas.
Thanks in advance!
