Another try - I have a Dell Dimension XPS-T600 with an intel series 6
598mhz processor.  It currently has two 128K memory strips (three
slots on board).  I tried buying three 256K upgrades from Dell Direct
and they worked fine. Problem is they're $80.00 apiece.  All the links
you post (shop.kingston, smmdirect.com, etc) are even more expensive! 
Are there any clearing houses or wholesalers that cater to us price
shoppers?  I'd like to wind up with 768K.  Many thanks for your help.
