I found a closed thread on this but it didn't have the answer. I am putting SP7 and patches on our MM 3.0 system tonight. It really has bogged down lately. I would like to add some memory. We have a lot of it around. I'd like to see if we have what I need. I have the s3400 with the integrated video and lan. Docs say it has two 256mb DIMMs but I am looking for the details.
