Memory Map

2.1.1

Addressable Memory

The board utilizes 4 GB of addressable system memory. Typically the address space

that is allocated for PCI Express configuration space, BIOS (SPI Flash), and chipset

overhead resides above the top of DRAM (total system memory). On a system that

has 4 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 Mbits)

•

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 Express add-in cards

•

Base graphics memory support (1 MB or 8 MB)

•

Intel® Management Engine Interface (Intel® MEI) single channel (8 MB) or dual

channel (16 MB)
