RAM Doctor is a smart memory management program that will keep your computer running more efficiently, faster, and longer. RAM Doctor works by freeing up physical RAM wasted by Windows and other applications.
The program's RAM Optimizer intelligently manages the free RAM that is available to Windows, and prevents your computer from running progressively slower over time.
