Not bad. 5/14/2020 4:28:11 AM

Pros: Stable, easy OC setup etc.

Cons: Some lack PCI lanes (but that's with this chipset) forces sacrifice of some SATA ports.
UEFI UI was meh with default BIOS. EVEN MORE MEH with bios update. *sigh*

Overall Review: Good pick for a Ryzen for me.

Overall Review: It's a great mobo for the performance

Low quality BIOS makes this board a dud. 4/24/2020 11:29:42 AM

Pros: It was cheap.
VRM's don't overheat.

Cons: Memory overclocking is pretty lackluster, but the real disappointment is the CPU boost behavior.
This board seems to handle boost much worse even on a low power part like the r5-3600.
It all comes back to the BIOS.
It's buggy as can be.
PPT doesn't work
EDC doesn't work
AMD Raid didn't work for some versions of the bios.
I am aware that the Ryzen 3000 CPU's rarely hit their rated boost clocks, but this board is just downright worse in performance on any and all applications when I don't have a static OC at 4100mhz.

On top of the many bugs and performance issues, I just found out it won't be getting AGESA 1.0.0.5 This is a slap in the face considering that this board still hasn't had a decent BIOS release to begin with, and it prompted me to actually write a review for once.

Overall Review: This would be a solid board if it wasn't for the BIOS, but I suspect updates are a dead end at this point.
