ok if a mobo say has 1000 mhz fsb then it can take a 500 mhz piece of ram right ? also what is ddr2 and ddr3 and how do they work compared to ddr? another question is if the mobo can take 400 mhz ddr but the cpu can support 500 mhz fsb or is 500 mhz fsb can u use 500 mhz ddr? at 500mhz ? or would u need 2 clock the fsb up in the bios to tht ? of the proccessor ?

lol i hope tht made sense this was written at 1:25am
