Memory BoostUp

Memory BoostUp is the best free RAM optimizer for OS X. Mac OS is very competent at managing your system memory, but manually freeing and purging memory can be beneficial to performance in some instances. We recommend running manual memory boosts prior to launching memory intensive applications such as graphic design packages, games and emulators. Memory BoostUp features an easy to use interface, as well as an unobtrusive menubar mode (and autorun option).
