I picked up a Crosshair VI the other week with one of those on the front and it booted the 2700X no problems, so I didn't even need to use the flashback function like I'd planned. It was running the 3502 BIOS from January out of the box, which came with AGESA 1.0.0.0a. Slightly surprising that had Pinnacle Ridge support.I have a system I'm waiting to build with a 2600X and a Gigabyte AB350N motherboard. The box for the motherboard says "AMD Ryzen Desktop 2000 Ready". Am I likely to run into this problem?
