  • WiFi 6 is awesome, and this is a very good board overall.
Style: B550M|G|M.2 x2|WIFI6 Size: mATX
I bought this to help my brother build a pc ( which I have never done before just changed parts on a prebuilt ), and it was fairly easy to install this into the PC case we bought, putting on the wires was fairly easy. Finding the Bios was kinda wanky but that was more in gigabytes such on their website, just do B550M and look for the that's says Gaming 6 on it. After that installing the Bios was easy just q-flash first try and easy to mess with settings. The ports on the back a held together and onto the board well so no worry about plugging and unplugging items. Overall really good, I didn't understand what WiFi 6 was until I watched the steam download speed being 300 mbps on his vs my 20 mbps. Performs very well. ... show more

  • Corrupted Bios
Style: B550M|G|M.2 x2|WIFI6 Size: mATX
Arrived with corrupted bios. Strange garbled characters all over the screen immediately after powering on. First time in my 35 years working on PC that I encountered such an unusual problem with it.
