FreeMem can display the tray-icon memory monitor in 3 different ways: 1. Chart, 2. Numeric, 3. Bar. The FreeMem application was designed to increase your PC's performance by optimizing Microsoft Windows memory management. You can avoid many system lockups by running this improved RAM-Optimizer. Optionally FreeMem can show a CPU monitor, too.
If one clicks on a specific amount of RAM (e.g. 12MB) and presses the button Allocate and Free, the tool goes into operation. The amount of memory is allocated and filled with dummy data.

It is necessary to fill the RAM with data as Windows is smart enough to ignore allocations which are never used. The memory is then immediately freed and returned to windows. The tool checks if the requested success was reached.
It is possible that Windows swaps out parts of the RAM FreeMem Professional has allocated and not all the other stuff. If the target was not reached (or nearly reached), the tool repeats the operation. It is possible that the wanted amount of free RAM is never reached. Some background programs can prevent this.
To avoid FreeMem Professional to continuously block RAM and waste CPU time, the user can specify the maximum number of tries the tool undertakes to free up RAM. You can see in the title of the window if the tool is already in a retry loop. A number is given in brackets which specifies the current loop number. More than 20 loops are not allowed.
You can choose the amount of RAM to free. It is important to not choose too much here as this will greatly increase your swapfile size and will take a long time. Only a good chosen amount of RAM ensures fast operation and performance enhancements. It is usually a good idea to free up half the RAM you have.
