Do AM4 motherboards with AGESA ComboAm4v2PI 1.2.0.7 still support Zen CPU's?

[A Computer Guy]

I might be able to snag a free MSI B450 Tomahawk and a free 2200g APU but not sure if the new UEFI updates still support original Zen CPU's.

In some cases I know Bristol Ridge CPU's are no longer supported.

I'm thinking it will work because I have a 2700x and 1600 AF on the 1.2.0.7, but there's only one way to know for sure if that particular board with that BIOS will run that CPU, and that's to try it. Worst case scenario you pull that 5950X and downgrade the BIOS. The Tomahawk has a flashback capability according to this, so you might not even need to use another CPU to downgrade BIOS if it doesn't work. I'm betting that it works just fine though.

I think it had to do more with the chipset/bios support, but I think 1207 supports them all?

I have an x370 and a 1700 on 1207 bios, no issues.

Tomahawk MAX or original?

Original board had a 16MB BIOS and for Ryzen 3000 support was forced onto a slim BIOS that removed support for some CPUs. But for MSI I don't think they removed anything other than Excavator APUs from the list (Bristol Ridge). So you're a-ok

What are you trying to gain from AGESA 1207? Every BIOS should be compatible.

Different vendors, but ASRock slaps a cookiecutter warning on every BIOS since AGESA 1003 that warns against flashing newer BIOSes for all Zen+ and earlier CPUs. Though, it might have something to do with them disabling BIOS rollback past a certain point, not sure if MSI has anything similar. They don't say

Tomahawk original so that is one reason I was worried about it with the limited flash space on those boards. I might pop a newer chip in there or put the 2200g back in it at a later time or I might re-gift it for the holidays for someone who needs a computer. If I recall the 1207 fixes the TPM stutter issue so if I put a newer 5000 or regift it I just want to make sure it will have as few problems as possible. If I have an issue it looks like I can use flashback to 7C02v10.zip according to MSI compatibility list.
