I've had horrible experiences with Gigabyte AM4 boards, three in total.
Two identically builded A520M S2H that I purchased for two Ethereum rigs in late 2020 died within the span of a month. One of these systems I gave soon after building it to a family member in exchange for a lower end computer since it was enough to mine. After a year, I had to troubleshoot it because it was not POSTing anymore after being told that the only thing that happened was powering off the computer the previous day. I decomissioned the other working mining system to do a full Motherboard + Processor + RAM swap because I had to get that system working ASAP. Then a month afterwards, same thing happened, so now I had two dead boards.
I later found out that it seems that
it was a BIOS bug. One board recovered after using Q-Flash, the other did not after multiple tries. By the time that this happened I already lost two months worth of mining and the Ethereum change that wouldn't make mining with GPUs viables was close by, so I got lazy and never rebuilded. So their deads means that I lost possible income.
A friend purchased a B450M DS3H WIFI. It worked fine for less than a year, then same thing, it just stopped POSTing. After my experience I suggested him to try reprogramming the BIOS, which he had to do externally due to no Q-Flash. After running a few months in circles until he managed to get tools that worked with his chip to reflash it, it didn't POSTed, either. So it may have actually died.
