Review: Functions as expected. - The motherboard is perfect, all the bells and whistles without breaking the bank. This is my first ASRock motherboard and I can say the build quality is first-rate. The software, however, is pretty poor and has an unfinished, amateur feel to it, not as good as ASUS motherboard software. ASRock’s advice on which BIOS to use is poor and their BIOS update descriptions are effectively non-existent. But the shipping BIOS is working for my build just fine so no worries there.
Review: Trouble with 5000 series processors? Think about updating the BIOS. - I kept getting random crashes with a Ryzen 5 5600X and BIOS version 1.20 (the first that supports it). After doing a clean Windows install and testing the RAM with memtest and passing 100%, I was ready to blame the motherboard. However, I decided to try updating it to the most recent version (1.70 at the time of writing), and lo and behold, the crashes stopped (so far anyway). So if you have a Ryzen 5000 series processor and are getting random crashes, try updating the BIOS. I also had a similar issue as another review regarding enabling XMP. After saving, my computer would just boot into a black screen. I had to jump the CMOS and unfortunately the board doesn’t come up with a jumper. However, you can just touch the pins with a metal screwdriver/paperclip for about 10 seconds or so and it’ll clear it up. So all in all, I think it’s a good board, and most of my issues were probably more on the processor side since it’s so new. This is my 6th year using ASRock motherboards, and I think I’ll continue to in future builds.

### ⭐⭐⭐⭐ Really solid motherboard for the price. Cheap no frills get the job done board
*by N***E on February 10, 2021*

Really solid motherboard for the price. Worked first try, easy to figure out, really basic but easy IO and fan ports. For the price, it was worth every penny. It's features are really limited but it's one of the most inexpensive b550 boards you can get. If you want a cheap, no frills, decent looking and gets the job done motherboard for newer Ryzen cpu's, look no further. The reason I DIDNT give it 5 stars is mainly the i/o shield (backplate). It's a REALLY disappointing piece... plain silver aluminum with no design, color, etc For $135 they could do better on that.
