Hello Bleeping Computer folks, I have a question.

Recently I replaced my old RAM with 2 new 4GB DDR3 (that means I have 8GB of RAM).

However, a recent FRST scan shows that over 3GB of the RAM is "cached", and the rest (a little more than 4GB) is free.

Can anyone explain this? I use Windows 7 Ultimate.

Thank you.

Caching RAM is RAM that is currently in use.

The ram is a faster type of memory where processes are transferred while they are running in order to making the loading and running of the process faster.

A cache is exactly what RAM is supposed to do.  Windows processes, running programs, and other services all transfer information to the RAM, but when they are closed, they are removed from the RAM but remain on the Hard Drive that they came from.
