Clearmem.exe  (Windows 2003 Resource Kit)

The Window Server 2003 Resource Kit is a set of tools that system administrators and engineers use to manage or support a Windows Server 2003 system.

Clearmem.exe - Clear Memory
Clear Memory (ClearMem) is a command-line tool that determines the size of the computer's physical memory, allocates enough data to fill it, and references the data as quickly as possible. ClearMem also accesses files to clear the cache. This reduces, to a minimum, the memory available to other processes. Then, the Clear Memory tool releases the allocated memory to restore normal system functions. Works on all versions of Windows starting with Windows 95.
