Occupied RAM indicated in Conky is different from RAM indicated in TOP. Why?

[floppy]

Hello,
here is the comparison Conky / TOP on my pc.  http://imagebin.org/163938
The RAM indicated is different: TOP indicate much more occupied RAM than conky.
Why? How to modify the conky parameters in order to have the same indication as per TOP? (my feeling is TOP is correct.. but just a feeling..).

Neither number is entirely correct; Conky doesn't count buffers and cache, but part of cache is the root filesystem and can't be freed.
