RAM usage always 68%

[JackGallagher]

I have the dials on on vista to see what is being used and even when i am just on the desktop with no programs open my RAM usage is always 68%, this worries me as it is right next to the red section on yhe dial.
What can I do to decrease this?

The criticality depends on how much ram you have installed in the first place. I don't think 15-18% is unusual if you have 2 Gb and run an antivirus.

So, 68% would be about right for 512 Mb of ram.
