you did'nt hit "quit without saving" by accident? sorry but that's all i can think of.
well i managed to change my 4x1gig (spd 5-5-5-18) of geil 6400 ull to 4-4-4-12 and just testing it without changing the mobo default voltage (easytune5 says its at 1.9v) it's passed memtest upto test7 (got bored waiting) and it's just done 30mins orthos blend test. seems this mobo is great with ram
when i changed the cas from 5 to 4 the pc powered down for about 1 sec then started up keeping the settings, weird, has'nt done it since, wonder what that's about?
