Memory slots 512, 1,024, 2,048 or 4,096MB memory modules
can be installed in the computer’s two memory
slots for a maximum of 8,192MB system memory.
This computer can be equipped with memory
modules of a maximum size of 8,192MB. 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.
Start -> Control Panel -> Appearance and
Personalization -> Personalization -> Display
Settings.
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 two 2 GB memory modules or more, 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.
