Im looking for advice on a memory upgrade.
I have two HP DL360 G5s that currently have 12 gigs of memory each. The memory consists of four 2 gig sticks and four 1 gig sticks. All slots are now full. I also have two 4 gig sticks that are available and I can use them or buy new depending on what works best. I would like to end up with 16 gigs of memory in each server. It would be great if, in future, the ram could be added to, if necessary, in the most economical way (simply adding without removing what is already in use) .
Whats the best approach to upgrade the memory now and have the ability to add more later if needed?
