sorry for the confusion, if the MB says it supports (example) 233/333/400 mhz ddr memory, thats pc2100/2700/3200 or something like that. and you put in for example pc4000 memory, something thats not listed as supported on the box, will the board detect that memory and run it at the correct speed, or will it slow the memory down? If it slows it down can you overclock the memory fsb to make the memory run at its normal speed? its not really overclocking, it would just be making the pc4000 run at its normal FSB speed, right? I hope i'm not confusing you now!

thanks for the links, I will read them right now.
