Many Thanks to those who replied in regards to the fitment of the RAM! However I am now looking for the best price for the following. I have so far found £35.
1GB, 184-pin DIMM, DDR PC3200 memory module
* Module Size: 1GB
* Package: 184-pin DIMM
* Feature: DDR PC3200
* Specs: DDR PC3200 CL=3 Unbuffered NON-ECC DDR400 2.6V 128Meg x 64
Which is £35 from the Crucial site....Is this a good price?
