Maximum Available Memory

See the table below for the maximum memory size that you can actually use on your system.

The maximum available memory is less than the maximum physical memory supported by your system

because some chipsets require PCI resource space of about 750MB. PCI resource requirements vary

depending on the type and the number of PCI cards you are using.
