Maximum Available Memory - NEC Express5800 Configuration Manual

CONFIGURATION GUIDE

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.
