How does that work for the PC I just got a month ago that has this motherboard and was advertised as having PCIe 5.0 ? https://www.memoryexpress.com/Products/MX00129652 I just lose capability that was clearly marked as a specific feature in the item I purchased?

Ah, I see that the PCIe 5.0 mentioned in the product specs is for the M.2 storage, not for the PCI slot for a graphics card. The post title should probably say "removes unofficial GPU slot PCIe 5.0 support" or something.

But yeah, considering I have a 5060ti 16gb on this motherboard, I guess I'll be staying with the current BIOS version indefinitely... Just checked with CPU-Z, it says Bus: PCI Express 5.0, current link width: x8 , current link speed: 16GT/s
