IÂ´ve tried to boot with 400x6 with default voltages and the ram speeds all set to auto but the system wouldnt post. I checked in the bios and realised that it only offers "667MHz (DDR2 1333)" or "800MHz (DDR2 1600)". I realise now that 1:1 just isnÂ´t happening automatically... no instructions in manual or in FAQ on ASrock`s webby.
Put the board into 1600FSB mode via a jumper setting, it allowed me to specify "400MHz DDR2 800" here but still does not post.
anyone have any ideas? thanks in advance
Oh, also, Memory (being DDR2) is dual pumped (so running at 400Mhz at double data rate is 800Mhz effective). When you set your fsb to 400, you were overclocking the ram to 1600 (your board does not provide the memory multiplier per say, just settings of what the speeds would be. that's why you see "667" then in parenthesis "(actual current speed w/ this setting)" and "800" "(actual current speed with this setting)"
Your ram would be running at 1600 with the 800mhz setting. I would set it back to the 667 setting for now (if that's as low as you can go), and increase the fsb until you see "(800)" next to it as that is your actual current speed.
