It appears that AMD is actively preventing manufacturers from releasing BIOSes that allow Ryzen 5000 Series “Vermeer” desktop processors to operate on older X370 motherboards. This is according to a support email shared on the Hardwareluxx forums, which includes a statement from an ASRock representative claiming that AMD had warned them against providing such BIOSes. AMD’s official Socket AM4 Motherboard Chipset Solutions chart shows that X370 was never meant to include support for Ryzen 5000 Series processors, but as noted in Wccftech’s coverage, red team did previously state that the AM4 socket would be supported until 2020—the same year that Vermeer launched.
Hi Jörg,
Unfortunately, we received AMD’s warning that X370 shouldn’t support Vermeer CPU.
Obviously, some customer didn’t operate it under table, AMD noticed it and said ASRock shouldn’t do this anymore.The attached file is BIOS and it is the last BIOS which I can provide for you in this case, please pass it to user under table.
