It seems that good news is coming, and it is that the ASRock X370 Pro4 has today received a new BIOS that adds support for AMD Ryzen 5000 processors and Ryzen 4000 APUs. This comes exactly one year after the release of the first AMD Ryzen 5000 CPUs, and just after AMD’s statement where valued official support for 300 series motherboards.
In this way, it seems that it is the first motherboard on the market that offers such compatibility. officially and with the approval of AMD.
This is good news, but it confirms what was already known, that this backward compatibility was being blocked by AMD itself, which forced its partners to even remove the BIOS that made their newer CPUs compatible with these older motherboards. basically this move is a year late, and more so when they promised full compatibility with the AM4 socket.
As revealed by ASRock itself, adding this support has been so simple, which only happened to eliminate support for some obsolete processors Bristol Ridge @ 28nm released in 2017 (7th Generation APUs). That’s it, with that movement there was already room to add support for the Vermeer family of CPUs (Ryzen 5000) y Renoir APUs (Ryzen 4000).
