Why is RAM at 25% usage at rest

[tidan_29]

I do not share memory with a video card. I have 4 MG of DDR2 and an AMD64X2 5600 CPU and a M4A78 Asus board.
A gaget (meter) of Win 7 shows I am using 25% of RAM while the CPU is at rest.
Is this normal and if so why is it?

Yes, this is normal.
Windows Vista/7 actively stores some of your most commonly used applications in memory to speed up starting them.
If the memory is required by another program, it is immediately freed and reallocated.

Ty very much outlw6669. It makes a lot of sense. Now I know.
I should have written 4 gb of DDR2instead of 4 MG
