I recently bought a cheap GX620 on ebay for my daughters first PC and it currently only has 1GB RAM.
After a quick look on ebay I came across some very cheap 1GB sticks at 5GBP each.....
Hyperam DBV1GBUD2641288 1GB PC6400 DDR2
Are these compatible with this machine as I read somewhere that generic RAM isnt compatible with some brands of computer??! seems a bit odd to me as RAM is RAM or so I thought. Also if it is compatible can I run 2 sticks of this RAM alongside the 2x512mb sticks of PC4200 that are already installed?
Any advice would be gratefully received

PC4200 is TOO SLOW for a GX620.
The ram must NOT BE ECC and Must Be Low Density INTEL Chipset Compatable Ram.
8 Gigs is Max with 64 bit CPU and OS.
I took the plunge and bought these sticks of RAM on the off chance they would work. Amazingly they did actually work a treat so this RAM was cheap as chips at 5GBP each :) The computer now runs a treat with 3GB of RAM. Plenty for anything my daughter needs to do with this machine.
PC2 6400 ram is fine. PC2 4200 is not. Glad to hear it worked out.
Actually SpeedStep its now running 2 x 512mb sticks of pc4200 alongside the 2 x 1gb sticks of pc6400 with no problems thus far. Thanks for your reply though.

@maikal - Read this thread and then inspect the motherboard on your GX620 for damaged capacitors. If you find any, the motherboard will have to be replaced...

PC6400 is more than fast enough (I don't think the chipset will run faster than PC5300 speeds.
Ideally, you want to install memory in matched pairs, so I would suggest you buy 4x the 1 GBP RAM sticks and not use the PC4200 stick currently in the system (the PC6400 RAM will be throttled back to that slower speed if you were to add one or three faster pieces to the system... You may not care, but at such a low price I'd try for that little performance edge with faster memory.)
As an option, many are reporting these systems can support up to 8 gigs of RAM, though not formally supported by Dell, so if you find a good deal on 2 Gig DDR2 RAM that may be an option (but 4 Gigs for 20 GBP is most likely sufficient).
