Reviews
Asus PRIME B350M-A, AMD B350, S AM4, DDR4, SATA3, M.2 (PCIe/SATA), Realtek LAN, USB 3.1 A, MicroATX is rated 3.0 out of 5 by 2.
Rated 3 out of 5 by from OK Board, Good OC options, but can't OC RAM, SATA Issues. Got my CPU to 3.8GHz no problem, but I cannot get my machine to boot with my Corsair LPX (3000) on any setting other than 2133Mhz, doesn't work with their RAM OC profiles either. Also my SATA PORT 0, intermittently fails. So had to move all my drives up 1 port to work stably. Latest Firmware will not fix either issue. And yes before you ask, tried different drives, SATA cables & SATA Power sources. Other than that, rock solid stability when OS loaded. I may look at other motherboards in the future, but this was all that was available to take my 5 SATA drives(lucky I've only got 5!!) at the time. I've just got a lemon me thinks, and sending it back to leave me without a running machine is not an option.

Rated 3 out of 5 by from Not typical Asus Purchased this board as part of a Ryzen build, and it felt really cheap and nasty. Not typically what I would expect from an Asus component. Spend a bit more and get a decent board unless you are strict on a budget.
