Ab350 bios upgrade for ryzen 3600x help

easy peasey
first tell wife and kids to go out the house (as this will be the only time 'they' trip the electric ,while your flashing a bios)
then reset bios to defaults
reboot and double check its at defaults
then flash to the bridge bios circa v3xxx
reboot to bios check version flashed
reset defaults again
flash to the v5xxx bridge bios
reboot to bios check version
reset to defaults
you dont need allinone if you have seperate gpu (its for the apu chips)
insert your 3600 (not sure why you want an X version) but hey its your money
then boot to bios check everything is detected
flashing further up than the 3xxx series bios is up to you and remember sometimes newer versions actually are worse than earlier ones
boot windows check everything is happy
then return to bios to set the XMP ram settings etc

Reset to UEFI defaults is an option in the BIOS, it's a firmware soft reset.
Doing this before a BIOS update helps prevent corruption and headaches.

As for upgrading your board, the only benefit would be PCIe 4.0 support and
precision boost 2. The first would be useful for faster NVME drive support and
the second will yield a small performance advantage but IMO, neither are really
worth it in a small form factor setup. I would take the proven stability of your
existing board over a negligible performance bump that may not even apply with
the thermals in your setup.

Just my 2c

Thermals would be the first concern. Honestly, in an SFF setup I would go with
a 3600 (non-x) so you can stick with the stealth cooler. Unless you are either
doing number crunching or using a high end GPU with hopes of high FPS in gaming
the 3600 should be more than adequate. A 3600 handles even high end GPUs more than
well enough for a 60fps+ experience. If you really need more CPU grunt then maybe
look at the 5600. The 5600 will perform close to the 3800x but use far less power
and generate a lot less heat. IMO, the 3600 is the sweet spot for an ITX build
though. It runs relatively cool for the performance it provides. If you really
want a power house I wouldn't be looking at an ITX setup, a slightly larger case
paired with an mATX board will open up your cooling options and allow more
powerful, typically hot running components.

Your setup can certainly accommodate the 3800x but you would need to run better
cooling than the stealth cooler, you will throttle so badly that you end up with
worse performance than the 3600.

It will certainly improve your thermals but an mATX board will have a better
VRM section and cooling, thus allowing more efficient heat dissipation. That
said, it should be perfectly adequate with a decent cooler and your ITX board
provided you don't overclock (pointless with Ryzen 3000 and beyond anyway).

That's the one
