So a year into this I've got a launch day 1800x and C6H. They still give me regular failures to post or boot (most often seeming to post, getting to the splash screen then locking at what should be the handoff to OS with 0d qcode), and recently got WORSE (not directly timed with a BIOS update). 6004 and these further problems led me to break down and try some G.Skill FlareX from the QVl, but this STILL fails to reliably post at stock settings, adding the lovely tendency to every few days, under light load randomly hard reset (I haven't run this ram through a full memtest yet, so it's vaguely possible that it's defective, but the post issues aren't new).
Should I just RMA the board at this point?
