if it's not a dual channel memory board (eg nforce2/AMD athlon xp) then
it makes no difference.

I suggest going to <a style='text-decoration: underline;' href="http://www.crucial.com," target="_blank">www.crucial.com,</a> and seeing what is recommended for your
system.

For example: PIII systems using the 440BX chipset usually (always?) can't
use 512 MB DIMMs, and if 256 MB DIMMs are used, they should be low-density.

Address scrambled. Replace nkbob with bobkn.

Well, I tried putting a 512MB RAM into my HP Pavilion (I forget the model
number, but I'll be opening it up later tonight, so I might dig it out),
and it would not "see" it. I had to get 2 x 256MB instead. There must be
documentation somewhere to say what the compatibility requirements are?
Check first, else you might also end up with a 512MB stick you can't use.

It depends on the "bank" . if you have two slots that could be one bank of
two (both slots must be filled) or two banks of one slot each (then you can
use one 512).

Not in my case. The machine would run fine with one 256MB memory. It just
refused to "see" any 512MB memory. Must be the way the address lines are
wired on the mobo, or in the support chips (or in firmware?).
