I know with mine i have to power off every time i change a bios setting. Have you loaded defaults, Updated bios, power off- reset- remove batt, back into bios load default, power off, entered req'd settings, power off (maybe a batt out reset but i know mine is happy if i only do that after a reflash). I took me a while to find a bios i was happy with, as newer isn't always better i don't know if maybe there mem or even mobo specific. When i first got the board i was pulling my hair out but i turn out to be a bad stick of ram
