AMD Pulls PCIe 4.0 Support on all non-X570 motherboards

AMD Pulls PCIe 4.0 Support on all non-X570 motherboards

Yesterday we reported that gigabyte is actively pulling inf PCI-Express 4.0 support from all non-X570 motherboards. AMD has now stepped it up and is has removed the feature from older chipsets in their latest AGESA firmwares. 

AMD has drawn consequences from the one-sided efforts of the manufacturers in the matter of PCI Express 4.0 on motherboards with pre-X570 chipsets. Along with AGESA Combo-AM4 1.0.0.3 ABB the support will be removed.

The motherboard manufacturers have partially defied the requirements of AMD and released PCI-E 4.0 on motherboards with older chipsets. A recent updated AGESA firmware now removes PCI Express 4.0 support on all motherboards with pre-X570 chipsets.

The rollout via BIOS updates has recently been started. Among other things Gigabyte distributes corresponding updates with AGESA Combo-AM4 1.0.0.3 ABB and notes in the change notes the remote support of PCI-E Gen4 when using a Ryzen 3000 processor due to the new AGESA version. A similar reference can be found in the mainboard models GA-A320M-H and Gigabyte X470 Aorus Gaming 7 WiFi .

Several motherboard manufacturers have added PCI Express 4.0 motherboards with on B450- and X470 chipsets. AMD announced before the launch of Ryzen 3000 and the X570 platform that PCI-E 4.0 only would be available on X570 motherboards. The motherboard manufacturers, however, wanted to upgrade their product portfolio on their own.

The update in the form of AGESA Combo-AM4 1.0.0.3 ABB is also accompanied by further changes. According to AMD, smaller issues with Ryzen 3000 processors have been resolved. In addition, AMD has adopted the warning "Event 17, WHEA Logger" in Windows Event Viewer and XMP profile compatibility for memory.

And because AMD is choosing not to support doesn't mean it can't work without issue on many boards...

No one ever said it can't possibly work, but that its unreliable and they are not willing to put their brand in the hands of motherboard manufacturers who don't have to spec pci-e 4.0 lanes who are more interested in making it "work" for the sake of competition then for the sake of making it work reliably.
