System Memory
The evaluation board supports DDR2 400/533/667 main memory. Two 200-pin SODIMM
connectors (one per channel) on the board support unbuffered, non-ECC, single and double-sided
DDR2 400/533/667 MHz SODIMMs. These SODIMMs provide the ability to use up to 1 Gbit
technology for a maximum of 4 GBytes system memory.
Note: Memory that utilizes 128 MBit technology is not supported on the Intel
Note: The SODIMM connectors are on the back side of the board.
Caution: Standby voltage is applied to the SODIMM sockets when the system is in the S3 state. Therefore,
do not insert or remove SODIMMs unless the system is unplugged.

Advanced Graphics and Display Interface
The reference board has five options for displaying video, VGA, LVDS, TVOUT, SDVO, or PCI
Express* Graphics. SDVO (MEC) and PCI Express* Graphics are multiplexed on the same pins
within the Intel
SDVO/PCI Express* Graphics Slot (J6C1) for a PCI Express* compatible graphics card or an
SDVO compatible graphics card, one LVDS connector (J5F1), one TVOUT connector (J2A1), and
one 15-pin VGA connector (J2A2B).

ICH7-M
The ICH7-M is a highly integrated multifunctional I/O controller hub that provides the interface to
the system peripherals and integrates many of the functions needed in today's PC platforms. The
following sections describe the reference board implementation of the ICH7-M features, which are
listed below:
•
Two PCI Express* (x1) connectors
•
Two PCI connectors
•
