Well if the RAM does fit your motherboard (I'm pretty sure it wouldn't because I
don't know of any manufacturers who build computers that are capable of holding
a 1 ghz chip of RAM and then stick 93 MB of RAM on it.  I'm not even sure if
they make a 93 chip or if there is a combo that will equal of to 93" then
loading up 1 ghz for hash isn't too smart, you'll probably cause the chess
engine to run very very slow.  If all you want the RAM for is chess, then a 128
chip or 256 chip should be fine, and you'll save a few dollars (or whatever
currency you might have).

As far as performance goes then 128 is pretty much enough for all games above 60
minutes. 4-16 is great for blitz.  I also read once in a Steve Lopez (Chessbase
article) that if you load hash in increments of 4 then it works more
efficiently.  I'm not sure if that still holds true or not because the article
was pretty old.  Here's the article, maybe it will be a bit more useful to you.
