ASRock Socket AM4/ AMD Promontory X370/ DDR4/ Quad CrossFireX/ SATA3&USB3.1/ M.2/ A&GbE/ATX Motherboard (X370 PRO4)

I was a little worried about buying a used motherboard but being over budget on my build and at just a little over 50 bucks I took a chance. Board came in original packaging inside anti static bag with everything included that would have come with it new. The board itself looked brand new. It was easy to install and I had no problem getting my Patriot Ram to run at proper speed. I'm pleasantly surprised by the quality of this used board and would buy another one in a heartbeat for a budget Ryzen build.

Honestly i 1/2 expected the mobo not to work or missing the I/O plate. Came in the original box w all the accessories. I stuck a Ryzen 5 pro 3400g in it and off to the races. I think it shipped w a 2020 bios but it recognized my cpu and I updated the bios. I am happy with the purchase and have been building PC's for 20 years.

Works well

I had a lot of trouble with this build. I flashed the bios before I knew that it needed a boot-kit to work. I ended up with multiple Blue Screens of Death. I then put together a boot kit with an AMD A-Series chip and the recommended all-in-one drivers and bios from Asrock. I cleared the cmos to set the bios back to version 4.5 and then I got nothing but a black screen. After a few tries, I removed the M.2 drive and rebooted. This time I got a boot error on the screen. Turned off power, placed the A-series chip in, cleared the cmos, replaced the M.2 drive, booted the computer, installed the drivers, installed the new bios, then restarted the computer. Finally the computer worked. I then could power off and replace the A-Series with the Ryzen 3 2200G and then boot the computer. I came really close to just sending this board back. It works great and there is no BSOD. I really wish that they had pre-installed a working bios. It would have saved me from a day of total frustration.
