Slot
A 512, 1,024, 2,048 or 4,096 MB memory
module can be installed in the computer's
memory slot for a maximum of 5,120 MB system
memory.
This computer can be equipped with memory
modules of a maximum size of 5,120 MB. The
actual amount of useable system memory will be
less than the installed memory modules.
Video RAM
The memory in a computer's graphics adaptor,
used to store the image displayed on a bitmap
display.
The amount of Video RAM available is
dependent on the computer's system memory.

The amount of Video RAM can be verified by
clicking the Advanced Settings... button in the
Display Settings window.
If your computer is configured with more then 3 GB memory, the memory
might be displayed as approximately 3 GB only (depending on the
computer’s hardware specifications).
This is correct because the operating system usually displays the
available memory instead of the physical memory (RAM) built into the
computer.
Various system components (like the video adapter’s GPU and PCI
devices like Wireless LAN, etc.) require their own memory space. Since a
32-bit operating system cannot address more than 4 GB of memory these
system resources overlap the physical memory. It is a technical limitation
that the overlapped memory is not available to the operating system. Even
though some tools might display the actual physical memory built into your
computer, the memory available to the operating system will still be
approximately 3 GB only.
