I bought one of these and got a lot of memory problems (bad crc). Somebody (bionich - reddit) posted a solution online. Change the BIOS setting in SATA where it says gen3, change it to gen2. After that, I didn't get any error (so far). I tested the FW4B all night successfuly. Will see if it holds, but I wouldn't trust this unless being close to intervene. I was going to put it in "production" in a house that stays empty, but I would better look for something more solid. I used pcEngines APU4D4 before and they worked well but it looks that they are not available anymore.
