Hi,

AM5 works pretty well in general but there are some issues you might
want to be aware of. As mentioned this
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272507 seems to
plauge various models and BIOS versions. I'm not sure it's the same
for B650 series as I only have one data point being ASRock B650M PG
WiFi running Beta BIOS 1.30.AS02/AGESA 1.0.0.7c which according to the
reporter works fine. As far as WIFI goes most uses "AMD RZ616" which
is a Mediatek controller and unsupported however there's work being
done bringing in the mt76 driver that should to my knowledge support
this controller. Regarding ethernet you more or less have three
options using the builtin controllers, Intel i225-V, Realtek RTL8125BG
or Marvell AQC113(C). Intel works out of the box using 14.0, no idea
about Realtek but I suspect that you need to use the port to get it
going and the Marvell controller lacks a driver. There's a NetBSD
developer hacking on a driver if you're interested getting that going
by porting it, https://github.com/ryo/aquantia . 

A word of advice, you'll need a beefy CPU cooler for the 95W+ "rated"
CPUs as they boost very aggressively and mid-sized air cooler might
cause it to throttle. Most Asus boards also supports ECC memory which
can be a nice feature.

Here's a good round-up of most if not all available models.

https://docs.google.com/spreadsheets/d/1NQHkDEcgDPm34Mns3C93K6SJoBnua-x9O-y_6hv8sPs/edit#gid=0

I'm personally happy with my ASUS ProArt X670E-CREATOR with 128Gb of
ECC memory (4 x MTC20C2085S1EC48BR) however be aware that you'll see
much slower memory clocks with 4 memory sticks especially dual rank
due to how DDR5 and current memory controllers works. Using the latest
BIOS available as of writing (1710) breaks SATA and USB among a few
other things while 1602 works fine.

Best regards,

Daniel
