    PC133 is the common, standard RAM, and DDR stands for Double Data Rate, which means it's twice as fast as PC133. And no, you cant mix them. A motherboard usually will only take one kind or the other, unless you get one of those stupid combo boards.

    ya, big difference in speed between ddr and sdram

    but outback is right, some motherboards have slots for both DDR and SDRAM

    but the kicker is you can only use one type of ram at a time, so if you put SDRAM in and DDR ram in the computer won't boot :p

    and the combo boards that I've seen only have two slots of each. Dont know how big a stick they'd take, though, but my guess would be 512MB.
