Our back shop desktop machine probably gets the most work out of all of the systems in our business with the exception of my own in the front office.
For the longest while we had left 2GB of RAM in that back shop system.
Prior to Windows 7’s service pack 1 the machine performed reasonably well . . . at least until there were a few windows open, IE tabs open, and maybe Word and/or Excel.
Lately, the machine was dragging more and more with the hard drive light remaining almost constant.
So, we finally had a bit of time to pull the box apart and upgrade the RAM.
The only things open on the box after adding 4GB of RAM for a total of 6GB is this Windows Live Writer window and an RDP session into another desktop.
Notice that the OS is sitting at 2GB of RAM used!
The numbers shown above would be a lot different on just 2GB of RAM. Watching in the Resource Monitor it was possible to see when IE tabs were being swapped in and out of the page file along with almost any other application that was open on the machine.
3GB of RAM would do for most folks, but 4GB or more is a consideration for power users or users that work with Adobe and other high end apps on a regular basis.
