Windows 7 Basic Question about Memory Usage

[edbro]

I have 6GB of DDR3 ram installed. When I look at Taskmanager I see:
Total: 6141
Cached: 4580
Avail: 4519
Free: 0

Does this look okay? Why does it say I have 0 Free ram? Everything runs fine so I'm sure it the way it is supposed to be but I was wondering about that 0 free ram thing.

You didn't say whether you were X86 or X64.

It is RC1 x64

edbro, this is absolutely (100%) right. This way microsoft system tries to add speed: it caches sys files if a portion of ram has not been used for a long time. If an app asks for ram, the system will unload some cached files so that the application can use the ram needed. Talk to Microsoft if you don't like it.
