The board utilizes 8 GB of addressable system memory.  Typically the address space 
that is allocated for Conventional PCI bus add-in cards, PCI Express configuration 
space, BIOS (SPI Flash), and chipset overhead resides above the top of DRAM (total 
system memory).  On a system that has 8 GB of system memory installed, it is not 
possible to use all of the installed memory due to system address space being 
allocated for other system critical functions.  These functions include the following: 
•  BIOS/ SPI Flash (32 Mb) 
•  Local APIC (19 MB) 
•  Direct Media Interface (40 MB) 
•  Front side bus interrupts (17 MB) 
•  PCI Express configuration space (256 MB) 
•  GMCH base address registers, internal graphics ranges, PCI Express ports (up to 

512 MB) 

•  Memory-mapped I/O that is dynamically allocated for Conventional PCI and PCI 

Express add-in cards 

•  Base graphics memory support (1 MB or 8 MB) 
•  Intel MEI single channel (8 MB) or dual channel (16 MB)
