That board doesn't support the 800 bus so your stuck at 533. there is no way to unlock the multiplier so at 533 you will run around 1600mhz. overclocking the fsb from 133 to 166 will get you up to 2 gig, but if you can't slow down the memory it won't run stable. i don't know the details of how the board will adjust memory speed and timings, but you won't get to 2.4 without a board that supports the 800 fsb (200mhz fsb times 12 multiplier = 2400)
