GIGABYTE AMD Motherboards Get Fitted with new AGESA Microcode (Solves the SMM Callout)
Gigabyte announced today the latest BIOS update just recently for AMD platform motherboards. It not only supports 3rd Gen. AMD Ryzen XT desktop processors, but also provides effective solutions for some of the hidden SMM Callout related security issues on the AMD APU.
GIGABYTE has been working closely with AMD to provide the best performance, enhanced user experience, and the recovery of security issues. After the previous release of new BIOS for Ryzen™ XT processors, GIGABYTE is also aware of the possibility of SMM Callout related security issues on AMD APU processors released from 2016 to 2019. The issue enables attackers to execute any coding and control the whole system through the system manage mode of AMD AGESA microcode.
At the time received the new AMD AGESA microcode, GIGABYTE RD confirmed that GIGABYTE BIOS with AMD AGESA Combo V2 1.0.0.2 and Combo V1 1.0.0.6 microcode, not only supports 3rd Gen. AMD Ryzen™ XT desktop processors, but also provides an effective solution for the possible SMM Callout related security issues on part of the AMD APU. Users can update the latest BIOS to motherboards through multiple ways such as GIGABYTE @BIOS, Q-Flash. With Q-Flash Plus on the X570 and B550 series motherboards, users can easily update BIOS without even installing a processor, memory, graphics cards, so they can enjoy the new BIOS easily and take full advantage of the new processors.
The latest Beta BIOS for GIGABYTE AMD X570, B550 motherboards has been uploaded to the official website. The latest BIOS for X470, B450, and other chipsets will be continually uploaded after the middle of July. Users can download to optimize their systems. Please visit the GIGABYTE official website for the latest BIOS update.

I've been using F20b on the master for a ~week from the tweaktown beta.
Solved some inconsistent memory training boot issues the F12 branch had on my system.

Some settings when dealing with voltages are a bit iffy for F20a and F20b on the X570 at least but more when doing manual tweaking whereas auto works and it's mostly on overclocking but it's still something that might need correction in a F20c test before F20 can be released without any of these beta denoting letters and however many revisions it'll go through first.

Probably the same for the bios releases for the B550's, 400 and 300 series meaning potentially some issues until Gigabyte feels confident enough to remove the beta label and however many bios revisions will happen before that's release ready.
Going by the article possibly mid to late July depending on what needs to be resolved still I suppose but F20a so far besides the virtualization option staying on regardless has been a good update although it is still a beta and has confirmed known issues.
"b" might have some other fixes too, I'm jumping to "c" or whatever is next since I don't tweak some of the options known to be a bit iffy.
But part of that is due to bios update compatibility between versions and having to re-apply settings though that's a good thing to avoid issues and it's mainly XMP plus offing CSM and setting the fan speeds particularly the little chipset spinner thing ha ha.

Harmless and all but hopefully passive can be more of a thing going forward and without the price premium although that "Elite" is a bit special besides the copper cooling job Gigabit did for that.
(Plus just setting the mode to silent is enough to keep it zeroed until it actually starts getting a bit warm which with good case cooling and passable ambient temps is just about never.)
EDIT: Oh and toggling off SATA hot swapping because ejecting (Non physically, thankfully.) the secondary HDD for storage by accident is a bit of a whoops.
