Tomahawk MAX B450 BIOS issues and questions
Currently my BIOS is one level below the support range for 5000 CPUs. If I upgrade now, will my existing Ryzen 5 3600 still fit after the latest BIOS update? Probably not—after that point you’d need a 5xxx CPU. Confirm. Also, reading somewhere suggests the 3xxx generation Ryzen CPUs won’t work with the newest BIOS. Thanks!
I believe the discussion centers around specific CPUs that are no longer receiving support after upgrading the BIOS to accommodate 5000 series processors, mainly because of EEPROM constraints. This issue primarily affected motherboards with 16MB or 128Mb BIOS chips. Your board isn't impacted by this restriction and a BIOS upgrade should work (thanks to the 32MB chip). For maximum boards, using a 32MB BIOS is recommended. See the details on the MAX motherboard page for more info, and check the BIOS version compatibility list for specific models.
It implies that upgrading the BIOS of the MSI B450 Tomahawk Max to the latest version allows using those CPUs whenever needed—just plug in and go.
Tomahawk Max maintains CPU compatibility even after BIOS upgrades. Should it lose any, similar to certain low-EEPROM boards, it would primarily affect older or weaker models such as the Athlon GE or non-Ryzen AM4 CPUs.
