Good review, HH...;) Never could figure out what it was about the x570 Master that you didn't like--I'm still using the mboard, and with the latest F20-F21 bios versions out it's better than it ever was--imo. Mobo finally officially supports ECC in the bios if that is of interest to anyone. Later revisions of the mboard also support GB's Thunderbolt 3 cards--the connectors are on Rev 1.1 and 1.2 of the Master, if that's of interest--it's not to me, actually. But the thing I wanted to say about the B550 is to point out the obvious, that the bios maturity run is just beginning for the B550's. That means several months or longer of bios teething problems, very similar to what I went through with x570 Aorous Master--that all of the x570 mboards had to go through--their own bios versions and fixes plus the changes from AMD's many AGESA's during the year. So I guess my point here would be that I consider the features in the x570 Aorus Master to be well worth the premium over the cost of a B550 mboard by themselves, but the one-year mature bioses for the x570 mboards is very nice icing on top! Just thought I would mention it.

Oh, my mobo 😀 . Was hard to buy. 😀
