If your computer usually runs out of RAM, RAMRush will be a really good choice for you and your computer.
This application works in the background and is always powering up the performance of your computer by cleaning up memory processes and freeing RAM.
You only have to click its icon and it will free up RAM, it's that easy and you'll see a log of what it has done. By that way you'll be able to know how better is the performance now.
Sometimes, some programs don't run as good as you would like because they need more free RAM and that's exactly what you'll give them using RAMRush.
