Greetings, all. I purchased a Dell 530S - several years ago and it has served me well. I upgraded the RAM to 4gb without problem. Now, however, I use many more memory hogging programs for work and in my mixed media hobby. I checked several years ago here and elsewhere about the possibility of upgrading the memory beyond 4gb, but learned that the motherboard was not built for that. Recently I have seen ads for ne 2gb single memory units which are alleged to work on the 530S. Would it be worth my time - and bucks - to try to do this? Many thanks. Bob G.
