Well after further use, 3/18 bios was fairly buggy and unreliable on my v1.0 board, failed to post many times(especially after a warm boot), and a weird 1-2second freeze in many games. Switched to the chb0325f bios yesterday-much better-cleared up the failed posts and freezes in games, but I'm getting low disk scores using the Atto HDD benchmark...disk performance seems normal in regular use though.
