ASRock has released a BIOS update for the X370 Pro4 motherboard with AMD X370 chipset that adds support for Ryzen 4000 (Renoir) and Ryzen 5000 (Vermeer) processors. It looks like AMD is really working on making motherboards with AMD 300 series chipsets compatible with the current generation of processors.
AMD keeps repeating that adding support for new processors to older motherboards is a daunting task. In large part, the problem is related to the limitation of the BIOS memory into which data is entered in support of certain processors. In addition, there are some issues related to the design features of old motherboards – not all are equipped with sufficiently efficient power subsystems (VRM) that can provide the stated level of performance for all models of Ryzen 5000 processors, motherboards do not support some technologies, for example the same one PCIe 4.0 interface supported by newer processors.
Nevertheless, unofficial modified BIOS versions for AMD 300 boards with partial support for Ryzen 5000 processors have already appeared on the web, some manufacturers even announced the release of official firmware for the boards, but then quickly removed their announcements and updates.
ASRock has released two BIOS versions for the X370 Pro4 that can be installed at the end to use the new AMD processors. However, the installation process requires some patience. The first step is to install BIOS version 7.00. It is ephemeral. The company warns that before installing on the X370 Pro4 motherboard, you need to make sure that the system is not using a Bristol Ridge series processor (AMD A series and Athlon X4 models) as the new firmware will have support for them Has removed chips.
After that, you need to install BIOS version 7.10, which has support for Renoir and Vermeer processors. The company does not recommend installing this version of the BIOS if PC owners have Pinnacle Ridge (Ryzen 2000 and Ryzen 2000 Pro models), Raven Ridge (Ryzen 2000G, Athlon 200, and Athlon 200 Pro), and Summit Ridge (Ryzen 1000 , Ryzen 1000 Pro) and has no plans to upgrade to Ryzen 4000 and Ryzen 5000 processors.
New BIOS revisions are available for the X370 Pro4 board that supports AMD Renoir and Vermeer processors on the official ASRock website… You will also find a list of supported processors there.
