Quote:Gigabyte releases new firmware with AMD's revised AGESA 1.0.0.3 ABB microcode for the brand's AMD 300-and 400-series motherboards. The latest microcode addresses a couple of issues with Ryzen 3000-series processors, but it also removes PCIe 4.0 functionality.

Either the AGESA 1.0.0.3 ABB microcode is the culprit here, or Gigabyte disabled PCIe 4.0 functionality out of its own free will. For now, it's impossible to tell because Gigabyte is the only motherboard manufacturer to deploy new firmware with the updated microcode. Once other vendors begin releasing new firmwares for their products, we'll be able to find out whether it was AMD or Gigabyte that pulled the trigger.
