2 Technical Reference 2.1 Memory Map 2.1.1 Addressable Memory The board utilizes 16 GB of addressable system memory. Typically the address space that is allocated for PCI Conventional 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 16 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 PCI Conventional 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) 41
