I have 512MB of cas2 crucial, & I haven't had any problems or slowdowns in games or apps either, but I decided to try memokit 2.5, memturbo 2.1, memturo 2.1 with cacheman 4.1, & memokit 2.5 with cacheman 4.1 & all these combinations produced no improvements in any benchmarks. Now would you leave these programs in there or is it better to uninstall it & free up the space? I have a 30GB & still have 28GB free, so space isn't too important.
