MemoryBoost helps your machine run faster, and more reliably, by recovering unused memory (or RAM). If memory becomes low, it quickly frees up some. MemoryBoost defragments your memory, further enhancing performance. And its SmartCPU feature keeps MemoryBoost from working while you're working; you won't even notice that it's there. Advanced features allow you to set desired and required levels of memory which MemoryBoost will maintain. Using MemoryBoost, your computer will remain stable longer and your programs will run faster.
