How Much?
- 64MB
- The bare minimum amount of memory you will want to have in
your system these days.
- 128MB
- A very good amount of RAM to have in your system.
- 256MB
- It wont be too long before this amount will be recommended, so
if you have it now, you won't have to worry about it later. The
good thing about RAM though is it will usually become obsolete
after you motherboard and CPU do.
- 512MB and Greater
- Probably a waste of money at this point. Only large systems
doing processes involving large files or pictures would need
this much RAM. The price drops fast enough on RAM that its not a
good investment.

DIMMs vs. SIMMs
- Check the motherboard you have or are planning on purchasing. What
kind of memory slots does it have, if its a newer board it should
have DIMM slots and if you are purchasing a board it should have
DIMM slots. Some boards come with both DIMM and SIMM slots, but that
is rare. Note SIMMS must be installed in matching pairs.

PC100 vs. PC66
- Speed
- Make sure you are buying the type of RAM that goes into your
motherboard some older motherboards only take PC66 DIMMs and some
will accept PC66 or PC100 RAM. If the board can accept PC100 RAM
be sure to purchase PC100 ram it is much faster.
- Parity
- Some motherboards don't accept parity RAM be sure to check to
see if your motherboard can accept parity RAM. Also you usually
have to stick with the same kind that you already have in your
motherboard if you are adding RAM so if you have parity now, you
need to make sure any additional RAM you add is parity. Usually
if you don't know you can be safe with purchasing non-parity RAM
as it will usually work in most motherboards.
