So I've narrowed my search to the following short-list, are there any here that I should stay away from (or highly recommend) ? Also, might there be any reason that any of these boards might not accept single channel (single stick) 16gb?

Hello! Just made an account to ask this: The latest BIOS L2.35, is this compatible with all boards with the 246 chipset?
