    • 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. ... show more

    • 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. ... show more

    • Has worked great for me so far.
This thing works great, has everything I need. Handles my Ryzen 7 and is supposed to be good for the next few generations too. It’s simple and easily handles my setup. (I’m not blasting it with RGB and heavy fans so I can’t say I’ve tested its full power) My only complaints- the latches for the GPU are sensitive and one broke, and also would be that the USB 3.0 pins are very fragile and also broke (maybe I’m heavy handed?) but there’s only one connection for them so now I’m without usb 3.0. There’s still regular slots it just stinks I’m down 2 (and they’re in the most convenient places) ... show more

    • Really solid motherboard for the price. Cheap no frills get the job done board Really solid motherboard for the price. Cheap no frills get the job done board
Review Image by Nate Elmore
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. ... show more

    • Has Everything I Need
Well- built and good looking. My first ASRock piece of tech and I'm so happy with the RGB support and PCI Express gen 4 support. Two m2 NVME lanes one gen 3x4 and one gen 4x4. Two GPU lanes one gen 4x16 and one gen 3x4. One m2 for SATA and one m2 for Wi-Fi key. A usb type c on rear I/O panel. I/O shield has holes for bluetooth/Wi-Fi antenna, just remove armor and rout wires, reinstall armor (gives cleaner look). I you want windows 7 you need a ps2 keyboard for installation. Otherwise no input is recognized and install is blocked. I personally had to install windows 7 first to do my free upgrade to 10. ... show more

I was surprised the motherboard work out of box with my AMD 5 5600x no bios updated required. Overall very happy for $104 was going to get the Asus Rog Strix gaming A but for price not losing out on that much. Would highly recommend to anyone looking for a motherboard.

This motherboard caught on fire after three days of use. My ground are fine. My PSU is fine. It was surge protected. My guess? Poor thermal strips or quality checks. Now amazon is replacing it and I have to build yet another computer praying it didn't damage my other parts from other sites because Amazon won't/can't refund those. ... show more

    • **WARNING*** Ryzen 5000 APUs will not work out of the box.
If you plan to use a Ryzen 5000 APU then you will need a different CPU to flash the BIOS. AND to add insult to injury, the motherboard doesn't support Ryzen 1000/2000 series CPUs. So if you were upgrading and hoping to use the old CPU to update the BIOS, think again. I had to field strip another Ryzen 5000 build that had a regular CPU to update the BIOS on this motherboard to get it work. That being said, the motherboard works well and has been rock solid. ... show more
