PC2-5300 or PC2-6400 512 MB, 1024 MB,

 

 

2048 MB or 4096 MB memory modules can be

 

 

installed in the two memory slots. Maximum

 

 

system memory size and speed are depending on

Main Memory

Part of the main system memory may be used by

the graphics system for graphics performance

 

 

and therefore reduce the amount of main system

 

 

memory available for other computing activities.

 

 

The amount of main system memory allocated to

 

 

support graphics may vary depending on the

 

 

graphics system, applications utilized, system

 

 

memory size and other factors. For PC's

 

 

configured with 4 GB of system memory, the full

 

 

system memory space for computing activities will

 

 

be considerably less and will vary by model and

 

 

system configuration.

■Your computer supports a maximum physical memory (RAM) of 4 GB. If your configuration has two 2 GB memory modules, only approximately 3 GB will be reported. This is not a wrong display, but a technical limitation of chipset, CPU and BIOS.

■In addition, a 32-bit operating system can not address more than 4 GB of memory.

■The reason is that various system resources (like Flash, APIC, PCI devices, GPU) require their own address space within the available

4 GB limit. In case of 4 GB of physical memory the address space used by the system resources overlaps the physical memory.

■The operating system has not the possibility to use the memory in the overlapped address range. This reduces the addressable memory space available to the operating system. Because Windows only displays the available memory instead of the computer’s physical memory, you will only see approximately 3 GB.
