I just posted about this in the forum section. I am looking for the type of RAM I have and there does not seem to be anywhere, not in the BIOS settings or in Device Manager that has that information. In my case, I even opened the box but the stick had no sticker on it or anything. If like me, you do not have any information because you "inherited" the computer and want to upgrade, it would sure be nice to have an easy place like Device Manager to find that info out. You can see what type of sound hardware you have and the network card ~ why can't you see the type of RAM? Plus it would sure make it a lot easier to upgrade if you knew that, since it is one of the easiest upgrades you can do that improves performance.
Just a thought.
