Last month there were some motherboard makers that enabled PCI Express 4.0 support on 400-series motherboards. This was against the wishes of AMD, who wants to keep PCI Express 4.0 exclusively for 500-series chipsets to ensure "everything just works" because not every 400-series motherboard can support it.

AMD's new AGESA 1.0.0.3ABB microcode update contains measures to prevent PCI Express 4.0 from being activated on older chipsets. German tech site ComputerBase noticed both Gigabyte and ASRock have already rolled out BIOS updates that contain this microcode.

AGESA 1.0.0.3ABB also contains various fixes, including an update that should get Destiny 2 running again.
