Why would anyone who has > added/increased RAM wish to remove/decrease RAM? I think you might be misunderstanding why someone would want to hot-swap ram. I used to work in a shop with a lot of Stratus minicomputers. They were designed to be up all the time. Everything was redundant and hot-swappable. Memory was expensive, and traffic might vary on different servers. So rather than ordering more boards, it sometimes made sense to move ram from one box to another. By far, though, the most common reasons you'd want to remove RAM would be if it failed, or if you want to replace it with a bigger chip. I agree that it doesn't seem to make much sense to pop in a chip just because you want to run photoshop, then pull it out when you're done. Walt Attachment:
