Great motherboard, after initial hiccup
Had lots of problems with freezes and unresponsive USB devices initially. But a BIOS update fixed it and now it is working great. Now I’m just typing junk because the review needs 30 words in total

Fantastic midrange board
Running this board with a Ryzen 5 5600, RX 6600, and 32GB of memory. I think the standout feature is the BIOS; the Uefi Bios is fantastic, easy to get around, etc. I do have a beefy cooler, but the CPU runs fast yet cool, and it was an easy building experience. Do keep in mind that the arrow for CPU orienting in the socket isn't painted, just indented, so be careful in that regard. Great board.

Needed a little tuning but works great
It didn't have display and no fan movement when I first turned it on but I simply took out the CMOS battery and that fixed it, this might simply have been due to Wootware support flashing the bios for me. Maybe the motherboard got confused during shipping. Also, My CPU wouldn't boost unless I swapped from their "optimized" bios preset to "normal" I've had no problems since!
