    Need a bit of help here... I have an HP P4 2.93 computer with 512mb of DDR2 "3200" ram. Is it possible for me to remove the (2 sticks of 256mb) 3200 ram and replace it with 2 sticks of 512 DDR2 "4200" ram? Thanks.

    It should work but might slow down to the speed of 3200.(I think I am correct with ddr2) Mobo Specs?

    If the specs you linked to are correct, you should have 4 memory slots. Your best bet is to install all 4 sticks, to get a total of 1.5 GB of RAM. The faster chips will slow down to the DDR2 3200, but you'll have more physical RAM.

    Yes, you can put 2 sticks of 4200 DDR2 into that MB in place of the existing RAM. It should auto detect the new RAM and run them at the higher speed.

    Your memory spec's:
    The "400" is 3200 RAM the "533" is 4200 RAM. 400/533 refers to clock speed, the 3200/4200 refers to memory bandwith. They are saying the same thing.

    If you mix 3200 and 4200 they will all run at the slowest speed.

    Don't expect a big speed increase from the faster RAM. It usually has slower refresh timings and will not be running synchronously with the processor FSB if the processor is 800 mhz and the ram is 533.
