A Chiphell forum user showcased the AMD Ryzen 9 5900X running on an older, entry-level A320 motherboard from ASRock. This indicates that some motherboard manufacturers may plan on supporting the Ryzen 5000 series on entry-level AM4+ boards, despite AMD’s claims to the contrary.
According to Chiphell forum users, AMD’s Ryzen 5000 series processors could run just fine on older AM4+ boards utilizing the A320 and X370 chipsets. A Chiphell user recently posted CPU-Z screenshots that appear to show a 12-core AMD Ryzen 9 5900X running on an ASRock A320M HDV motherboard. This indicates that motherboard makers may be working on bringing Ryzen 5000 support to 300-series motherboards, despite AMD’s claims to the contrary.
Officially, Ryzen 5000 processors will only work on B450 motherboards and up, with owners of older motherboards limited to the Ryzen 3000 series. The Chiphell screenshots indicate that just about any AM4+ board could, theoretically, support Ryzen 5000 processors.
This would let owners of first-generation AM4+ boards extract a remarkable amount of value out of their motherboards, with five generations of Ryzen processors supported.
The fact that these motherboards can run Ryzen 5000 processors doesn’t make them ideal platforms, however. A320M motherboards, in particular, don’t support overclocking. Moreover, older AM4+ boards lack support for the PCIe 4.0 standard, which could potentially impact gaming performance when pairing a Ryzen 5000 processor with a high-end Big Navi card like the RX 6800 XT.
