AMD Releases AGESA ComboAM4 1.0.0.5 Microcode
AMD formally announced its AGESA ComboAM4 1.0.0.5 microcode. The new microcode is intended to be encapsulated into motherboard UEFI firmware updates and distributed by motherboard- and OEM desktop manufacturers, at their discretion. AGESA 1.0.0.5 improves POST (time) with select Micron Technology DDR4-3200 memory chips. An intermittent virtual memory error with certain Realtek onboard Ethernet PHY chips has been fixed. The microcode also improves PCI-Express bus stability and interoperability, in general. A PCIe lane configuration issue with Ryzen 3 Pro 2100GE has been fixed. Besides these, all other performance- and stability-improvements part of older 1.0.0.4 a/ab/abb/abba microcodes are incorporated into 1.0.0.5. Keep an eye on the BIOS updates section of your socket AM4 motherboard's product page on its company website.

I will most likely update when Asus does release a new BIOS version with AGESA 1.0.0.5 for my ROG Strix X470-F, but I am happy to wait a while if it means it will work properly.
I used to have Gigabyte AB350M Gaming 3, Gigabyte is quite supportive as they have beta BIOS in their own forum and you can request for your board BIOS so user can test revisions of BIOS before they released.
Version 1407 2020/04/1015.38 MBytes
PRIME X570-PRO BIOS 1407
"1.Improve system stability
2.Add BCLK Frequency and SB Clock Spread Spectrum items into BIOS Advanced mode. "
Will check back in a few weeks to see when a new bios is released on this AGESA version.
My G.Skill RAM uses Samsung chips which are not known to be problematic
Or if they haven't, there can be only one update coming for Ryzen 4000 series support.
B450 MAX and X570 might continue receiving updates.
Maybe this is the last one.
Once I plug the drives back in everything start up normally.
As far as I know all their B450 and X470 MBs support Ryzen 3000 CPUs and so do almost all their B350 and X370 boards and even some of the A320 boards do.
Look at these:

It seems like Asus is only regularly updating their B450 and X470 or newer BIOS.
It does look one version older, though, due to the date:
May mean that a newer version has just been released. Only God knows if or when we are going to see it.
I was able to reach 4.250ghz max boos all core on idle and 4.150ghz on load cpu v 1365 vsoc 0.900 CBO enabled LLC1 spread spectrum disabled on my 2600x aio colling 60 degrees
Now with same settings I am going to 4.207ish 65 degrees
I will probably revert to previous bios

I tried up to v16 bios version for this board (from "launch" to V12 .. v12 beta - v13 - v14 beta - v14, v15, v16 .. the only 2 fairly stable was the v12 (just after launch bios, which my board came with)current on the v14 one.. sadly the v14 does not "let me" use my ram at 3200 speed, I had to tone back to 3000 speed (but was able to tighten the timings down from C16 to C14 as well reduce volts that way)
the problem overall was that any above V12 - v14 are anthing but stable, even when seemed to be stable, quick run of almost anything would cause lockups .. where v12 got me my 2nd to highest CPU-z benchmark scores I have gotten thus far, v13- v14 touch less, but also touch less volts to the CPU
Agesa might have improved various things, overall, seems MSI has not used this to the best advantage either IMO .. especially with the !@#$ Nahimic crud .. have to do odd freaking installs of the Realtek driver, then nahimic, then through Windows store etc.. sad because the way it "shipped" prior to any fancy driver DL, got the full fledged driver stack, not anymore .. quite hate things that do not work right, when simple should be "maintained" so it, well, just darn well works
