AMD Ryzen 5000 Zen 3 CPUs spotted working on A320 and X370 motherboards
AMD mentioned that Ryzen 5000 processors would only be compatible with A520, B550, X570 motherboards initially, then a few months later in January 2021 the AMD X470 and AMD B450 would get supported. But wait Dave, there's more.
So, motherboards equipped with an AMD 300 Series chipset would /should not be compatible. However, it appears that a number of companies already have BIOS ready for A320 and X370 motherboards , which enables compatibility with AMD Ryzen 5000 desktop CPUs. According to a Chiphell forum member, AMD 300 series motherboards can fully support Ryzen 5000 series processors and one of those motherboards has been shown to be the ASRock A320M-HDV, one of the cheapest on the market.
The motherboard was fitted with a 12-core AMD Ryzen 9 5900X processor along with 16GB of DDR4 memory, it is even compatible with AMD's Ryzen 4000G Renoir APUs. It appears that motherboard manufacturers have BIOSes for the X370 and A320, although they are not expected to implement these anytime soon as AMD has officially stated that Ryzen 5000 desktop CPUs will only be compatible with 400 and 500 series motherboards.
Overclock.net forum member, Brko, has revealed that Gigabyte already has Ryzen 5000 CPUs running on its X370 motherboards. It also appears that the BETA BIOS is included with the existing AGESA 1.1.0.0 code. The motherboard was fully compatible with the Ryzen 5000 CPU but had PCIe Gen 4 disabled.
16MB ROM capacity is a major limiting factor and will eliminate support for other generations, keep that in mind though.
Gigabyte and ASUS BIOS support for AMD Ryzen 5000 desktop CPUs is now available. Gigabyte offers BETA support on a total of 16 B450 chipset-based motherboards, while ASUS offers BETA support on a total of 16 ROG STRIX, PRIME and TUF Gaming products.

Now show me SAM running on a B350/B450 motherboard with a Gen 1 or 2 CPU and a simple mod BIOS/Driver hack. AMD slowly turning into Intel.

Supporting older mobo is a delicate cooperation between the cpu maker and the motherboard makers.
You do not want make motherboard vendors angry because they have to write and tests 150 bioses for motherboards sold 3 years ago at 80 dollars.
Is for sure possible to support it, the socket is the same, the chipset does basically nothing, but marketing wise it does not make sense.

Asrock for a long time has always been my no.2 mobo supplier, usually replacing different brand failed board. They always have interesting solutions, generally support cpus above their mobo class, decent prices and software support.
It does not suprise me one bit they came up with this kind of solution. It may piss the other motherboard manufacturers off, but I appreciate it as a consumer.

3 years is not very long support. Many of the x370 motherboards cost a lot more than 80 dollars. The BIOS is the same for most motherboards in the range for example if you compare any b350 Asus BIOS with any other Asus b450 BIOS using a hex editor the code is very much the same apart from the name strings and a few options enabled or disabled. AMD produce most of the code in their AGESA and probably contribute in other ways to the development. What makes sense marketing wise is what the end user will accept which is how b450 motherbaords got support after the reaction.

Asrock will always come up with stuff like this. I remember the time of DDR2 and DDR3 modules on the same board, or somehow ultra low end mobos with extreme CPUs. The only question is longevity.
