I'm also showing 7.9GB like I do without Rapid Cache in the Task Manager, and Samsung Magician is using 19.9MB so I'm not sure where Rapid Cache is. I have 8GB installed presently and I think there's a glitch because it says '138161' which is more memory than I have installed. It seems to scale automatically, and from what I can tell it only uses 50MB if you have 2GB of System RAM (2048MB). I know it's a month old but I just saw and thought I should respond.ġ) Rapid Mode uses 'up to 1GB'.
