    Ok firstly - you're going to need to update to F11 BIOS version (do not get any later - they present problems). Secondly ramp up the Row cycle time as high as it will go. Then depending on what speed your processor/FSB is running your RAM will equate to different speeds.
    For example:
    Let's say you have an AMD 4600X2 which has a 12xmulti.
    This if you keep it at the same speed whould allow your RAM to run at 400MHz. however if you overclock it won't- this will change probably meaning it runs to fast and won't run, or it will lower the speed significantly to get it to run.
    So let's say you overclocked to about 2.75GHz stable with the 12x multi and 230MHz FSB/HTT. Instead change the multi (clock ratio) to 11.5 and run with a 240MHz FSB/HTT allowing your RAM to run at about... 395MHz if you set it to Manual speed DDR 667. The overclock will boost your RAM to the closest to your desired 400MHz.

    How knowledgeable are you about overclocking? - Just so I know.

    If you need more help I know this board like the back of my hand- send me a PM.
