I have a Pentium III 800 mhz laptop running Windows XP Home Edition. My computer has two memory bays and currently has one 128 mb SDRAM SO-DIMM module in it.
What performance increases could I expect by adding an additional 128 mb of SDRAM? Maximum capacity is 512 mb; how much additional benefit would that doubling of memory produce.
Should I try and always match the amount in the two memory bays (i.e. is adding a 256 mb SDRAM to my current 128 mb SDRAM not recommended?)?
What are good brands of SDRAM for my laptop?
