GIGABYTE eliminated PCIe 5.0 functionality from the B650 motherboard firmware through recent updates. Reddit user Rejumi reported losing graphics card PCIe 5.0 access after installing BIOS version F35 on a B650 Gaming X AX V2 motherboard. The company subsequently withdrew F35 from support pages and released F36 as replacement firmware. AMD B650 chipsets lack official PCIe 5.0 support for primary graphics card slots despite previous BIOS availability. User complaints regarding GPU compatibility issues prompted GIGABYTE to disable the feature entirely.

The manufacturer never marketed PCIe 5.0 capabilities for the B650 product lines. Current flagship graphics cards from AMD and NVIDIA operate effectively within PCIe 4.0 x16 bandwidth limitations. Performance degradation becomes apparent when the lane configuration drops to x8 connectivity—eight-gigabyte graphics cards like the GeForce RTX 5060 Ti experience notable impacts under reduced lane scenarios.
