AMD Ryzen 5000 Processors Working on 300 Series Motherboards?

Chiphell user chm128256 has shared screenshots showing AMD’s new Ryzen 9 5900X processor running on an ASRock A320M-HDV motherboard. The implication is that Zen 3 CPUs are compatible with the 300 Series chipset, which is amusing, being that official support is relegated to the 400 and 500 Series.

Owing credence to the theory is an overclock.net forum user, who claims to know someone who has successfully paired a Zen 3 processor with an X370 motherboard.

“I have a solid info personally from a guy who runs Zen3 processor on… wait for it… X370 GIGABYTE MOTHERBOARD,” Brko wrote. “It has beta BIOS with AGESA code that supports Zen3. PCI-E gen 4 is disabled. Everything is running normal and no problems whatsoever.”

AMD officially extended Zen 3 processor support to the X470 and B450 platforms after catching flak from Ryzen users who weren’t interested in upgrading to the latest motherboards, but it seems unlikely that it’ll do the same for the aging 300 Series chipset.
