Hello, I see you're working on a custom build and need some guidance. You noticed that components function outside the case but struggle inside the case, especially when using the Radeon Pro WX 9100 in the Asus Prime Z690-p WIFI D4's Gen 5 PCIe x16 slot. After several troubleshooting steps—reinstalling parts, updating BIOS, adjusting BIOS settings to Gen 3, and changing the slot—I found it worked better in a different slot. The performance difference between Gen 5 and Gen 4/Gen 3 slots appears significant. If you need further help or want to confirm real-world results, let me know!

A PCI-E 3.0 card behaves like the Vega 64, yet it fails in a PCI-E 5.0 port but runs fine in 3.0 or 4.0 slots because speed above 3.0 doesn’t guarantee compatibility.
