Need: 2GB PC 4200 DDR2 533MHz

[Nathan O'Brennan]

I'm trying to breathe some last breaths into an old computer my kids 
use. It has 4 slots which are currently occupied by 1 GB DIMMS. I 
searched a bunch of Dell forums and some people were able to get this 
system to upgrade to 8GB of ram while others could only get the 4GB to 
work. I don't want to waste any money here, so I'm hoping to find 
someone who has 2GB PC 4200 DIMMS they are willing to part with?
