Monarch Computer is having sale on the ddr2 ram that my pc has in it. I have 2meg now. I downloaded a ram meter. I opened CS, Nikon View, Nikon Editor, Google earth, turned on the TV tuner card, Firefox, Thunderbird, had Spybot run a check. I then opened and duplicated a raw file , did some levels and filters. I was not able get the ram meter above 65%. The cpu did go to 85 %. (3 meg). I had thought my crashes with CS were due to lack of ram, but that doesn't seem to be true. Maybe it is just the typical Windows hangs. Or was my torture test not that tortuous.
