i dont really understand the question but if you mean why do i need the memory modules well its to build my computer and im waiting for my last parts (being shipped) to finish the build and i was checking the website of the specs of my mobo and found it had limits. (i had already bought a 2x1gb ddr2,533(pc4300)
and it only said 533 (didnt state whether pc4200 or 4300)
