memory usage

[alex4evr]

Hi guys,

I have different values of memory usage when using "top" command and System Manager. Top command shows much more (approx. the double) memory usage than System manager. Which one is the correct value and whats the reason for this behavior?

Regards;
Alex.

Memory usage snapshots are difficult in general.

Does 'top' show you the 'Cached' memory? There's the difference.

Shall I do something before memory upgrade and after the new memory card installation?

Thanks;

No, linux will recognize automatically the new memory capacity.
