i just installed 4x1g ram on to my asus p5k premium board, using the 0404 bios.
after a few days, i noticed that if i power down the pc, it wont boot up(no post, no beep) when next i turn it on(but everything is fine if i hit the restart button, or reboot in windows). it also works well if i only plug 3 dimms onto the board.
if i turn it off, i will have to take 1 dimm out, makes it boot(everything went back to default setting at the post screen), get into the bios screen(all my settings are still here), and save&exit. after exit, the power will be shut down again, i need to put the ram i took out before back in, in order to have 4g ram running...
i have treid almost all settings in cmos, and all version bios for this board, but nothing helped. also i have tested with prime95 blend, passed 8+ hours. memtest86+ dos version passed 2 times. all seemed stable enough. temps are pretty low too.
the system also crashes like once a twice a day(not even under heavy load, just bowesing the web)
