Memory
Module slot512MB, 1,024MB, 2,048MB or 4,096MB memory

 

modules (DDR2-800) 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.

 

 

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.

Video RAMThe amount of Video RAM available is

 

dependent on the computer’s system memory.
