Slots 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
the model you purchased.
Main Memory
Disclaimer
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.
