My tx2500 came with 2gb memory. Surely enough I thought. When the system booted up and settled down, it was using 7-800 mb. (about 1gb free because the video consumes some). But, as soon as I started loading up apps (Photoshop Elements 7, IE7 and a couple of minor apps) it took off like a rocket and consumed most of the free memory till I was left with around 150mb free and I could "see" the system swapping like crazy. So, I just replaced one of the 1gb modules with a 2gb one and rebooted. Now, it uses around 1Gb as the base, but I have 1748Mb free. So, an observation and a question. Put more memory in and the "used" goes up (comment) - is this because Vista is intelligent and starts swapping out real early (question)? If not, what are other peoples systems doing? Alan PS - this is my build, not HP's. I have Vista +SP1, MS-Office, Mappoint 2009, MS-Reader and PSE 7 plus a couple of extra gadgets.
