XP memory?

[Guest]

I will start off by saying there is nothing wrong with my computer, and my
question is mostly academic. My Sony laptop running XPSP2 has 512 mbs of
installed memory, just for the heck of it i used calculator and added up all
the running processes memory use and it came to 208 mbs, but in the available
memory field of Process Explorer it shows 205 mbs, where is the rest?

Shared Video Memory?

Shared Video Memory?

I don't think so . It is an ATI mobility with 8mbs of memory. I bought my
computer in 2002 and that's all it came with.

The kernel itself, kernel data structures and objects plus all
drivers (xxxxxx.sys DLL modules).

Control Panel / System / Hardware / Device Manager / View / Show
Hidden Devices - expand Non-Plug and Play drivers and there are a
few.....

Like another poster said, it's being used by system code and drivers.
Also, keep in mind that adding up the values as you did is a bit skewed.
Because processes can use the same dll's (shared dll's) the dll's
memory usage will be counted and added to each process' memory usage
even though it only uses 1 actual memory count.

Instead of adding and calculating the totals as you did you can just use
Perfmon and under the Process Performance Object add the "Working Set"
counter for the "_Total" Instance. It will save you from having to
manually calculate the list but keep in mind that the counter will also
add shared dll memory usage multiple times.

Ok, thanks all.
