Have you heard of
Total Ram booster?
As it stands, Total Ram Booster is the best Ram boosting app you can get for your Android device.

Total RAM Booster is not just another task killer. It has a newly developed innovative RAM optimization technique named ?Reduced Wake Up Optimization?. It scans and find the most ?waking up? apps and freezes/kills* them without root/super-user permission for a better RAM Boost.Total RAM Booster gives you lot of dedicated RAM share for gaming. A must have for all devices.
The intelligently designed booster engine will keep eye on RAM used by apps that are on background, and freezes/kills the background tasks which will end up in giving the ?forefront? app a big RAM usability share [i.e the top most displayed app/game will get more RAM share and resources]. Thus when playing high end games, if you feel that your device is slow or lagging, just minimize the app/game and boost your RAM using TRB or just use TRB widget for that lightning speed gaming experience. Or just set the Auto Boost feature on. It's that easy
