Not too widely discussed, but it is proper for this OS. In fact some notice reduced performance with maximum RAM.
I have a Acer Aspire E650 desktop pc.It came with 2gb of memory from the factory. I just added 2 one gig sticks, my system is showing that I have only 3,320 MB of memory. What happened to the remaining 776 mb of memory??? I read in another forum about this same issue with a E 650 machine, but.... can't remember where the forum was..LOL
