1. there is no direct relation between the actual memory on the board, 
and that used by X ... X also needs RAM for tables, objects, buffers,
etc,
that may or may not be located on the board's RAM.

2. there are also memory _mapped_ things (ex. graphic processor's
registers)
that are _not_ really memory but are accessed using memory interface,
so X
sees them as memory.
On modern graphic cards the memory range for such can be huge (several
MB)
but I repeat, this is _not_ real memory, it is only _seen_ as such by
software.
