Installed a second RAM stick earlier today, same as the one i already had.
it used to be that with 2GB of ram and running Rosetta@Home, all the ram would be used, plus 20-25% (1GB) of virtual ram (paging file=4070GB);
worse, when there was only about 50MB of free ram left, TuneUp Utilities would defrag the ram and that would slow down the cpu's work for a while.
Also important, pc's now ready for the summer as i changed the front and rear stock fans for 2 Scythe SY1225SL12SH,
110cfm, 37dBA. They make a wind tunnel noise but it does not bother me because temps have gone down about 10C or more.
I did have a look at this fan:Delta AFB1212GHE 120x38mm Rev. C Grand High Speed, but i thought that would be overkill, and maybe those fans would rip the insides and shred them out through the back fan, or the pc would start hovering and fly away! ;-)
