Gigabyte’s removed PCIe 4.0 support from their 300/400 series AM4 motherboards
Gigabyte’s removed PCIe 4.0 support from their 300/400 series AM4 motherboards
That’s right, Gigabyte’s latest 300/400 series BIOS updates are removing PCIe 4.0 support from systems using a Ryzen 3rd Generation “Matisse” CPU. We have confirmed that motherboards such as the X370 Gaming 5 and X470 Aorus Ultra Gaming have already seen this support removed with their latest AGESA 1.0.0.3 ABB BIOS editions.
At this time it is unknown why Gigabyte is removing PCIe 4.0 support, though it is possible that AMD’s latest AGESA update may have something to do with it. With Gigabyte being one of the manufacturers behind the push for PCIe 4.0 SSD storage, it is unlikely that Gigabyte would remove support for PCIe 4.0 without external pressure.
If this change is related to AMD’s latest AGESA versions, PCIe 4.0 support may be removed from other 300/400 series motherboards. This means that similar updated may come from ASUS, MSI, and ASRock over the coming days/weeks.
