To increase the random-access memory (RAM) of your computer, you must know the type of RAM it uses, how the RAM is presently configured and how many open RAM slots are available.
Check the owner's manual or motherboard manual to determine if RAM is parity or non-parity. The website of the company you purchased the computer from usually will tell you what kind of memory your computer needs as well.
Find out whether the computer uses regular, FPM, EDO, or Synch DRAM.
Purchase additional RAM that matches existing memory specifications.
