Default How come RAM is taken away for video cards? Because of my videocard's VRAM?

Like I have 3 GB of RAM, but Windows show 2.5 GB. I was told
because it is a shared memory?

Thank you in advance.


Are you sure it's not 4 GB of RAM, but Windows showing only 3.5 GB ?
On a 32 bits system, some of the addressing space must be mapped to IO
board... historically, the IO were mapped at the top of the 4GB
address space (of the 32 bits), alas with 4GB memory being now
available, that trick does not work... or rather still work too well,
and then some memory cannot be used as such.

Please describe your motherboard & CPU (name them at least), and your
version of windows.

And how you get the measurement.
