Very interesting the montage that has gone 'viral' in the last hours. Someone has decided to put an AMD Ryzen 9 5900X processor on an A320 chipset motherboard. This is the simplest chipset with which one of the new Ryzen 5000 can be assembled. Here the thing is not so much the chipset, but the number of VRM phases of the Biostar motherboard.
Specifically, the AMD Ryzen 9 5900X has been mounted on the ASRock A320M-HDV R4.0 motherboard with a 4 + 2 phase VRM design. Furthermore, these VRM phases lack a heatsink, which could be a problem in the medium and long term. It is interesting that it works, but it will hardly support load.

The A320 chipset by means of an update could support the AMD Ryzen 5000 processors. Something that is usually common in terms of backward compatibility between processors and chipset. One thing is that something can be done, as an experiment and another that it is something recommendable and add load.
We can mount the Ryzen 9 5900X on this base plate and use it for office automation and multimedia, without problems. The thing will be when we apply load to all cores, that problems should appear. The VRM phases will hardly be able to supply the necessary voltage for the processor to work. If they did, we would have an unmistakable temperature problem in the VRM phases and could end up breaking everything.
Someone has gone a bit further and it seems through a beta firmware a Ryzen 500 can be installed on a Gigabyte X370 motherboard. According to AMD this is not possible and we could also see that it was capped by AMD as it happened with PCIe 4.0 when the Ryzen 3000 were launched.
An interesting experiment, without a doubt, but difficult to take further. Creating a heatsink for those VRM phases could be a solution, which could add stability to the system. We'll see if more information comes in and they do some additional testing.
