Memory Configurations
The 3rd generation Intel Core processor family and 2nd generation Intel Core processor
Processors support the following types of memory organization:
• Dual channel (Interleaved) mode. This mode offers the highest throughput for real world
applications. Dual channel mode is enabled when the installed memory capacities of
both SO-DIMM channels are equal. Technology and device width can vary from one
channel to the other but the installed memory capacity for each channel must be equal. If
different speeds SO-DIMMs are used between channels, the slowest memory timing will
be used.
• Single channel (Asymmetric) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a single
SO-DIMM is installed or the memory capacities are unequal. Technology and device
width can vary from one channel to the other. If different speed SO-DIMMs is used
between channels, the slowest memory timing will be used.
• Flex mode. This mode provides the most flexible performance characteristics. The
bottommost DRAM memory (the memory that is lowest within the system memory map)
is mapped to dual channel operation; the topmost DRAM memory (the memory that is
nearest to the 8 GB address space limit), if any, is mapped to single channel operation.
Flex mode results in multiple zones of dual and single channel operation across the
whole of DRAM memory. To use flex mode, it is necessary to populate both channels.
Graphics Subsystem
The board supports system graphics through either Intel Graphics Technology
Integrated Graphics
The board supports integrated graphics through the Intel® Flexible Display Interface
(Intel® FDI) for processors with Intel Graphics Technology.
NOTE:
If using a processor with integrated graphics, the board will support only two of
the integrated graphics interfaces simultaneously: VGA, HDMI.
Analog Display (VGA)
The VGA port supports analog displays. The maximum supported resolution is 2048 x
1536 (QXGA) at a 75 Hz refresh rate. The VGA port is enabled for POST whenever a
monitor is attached, regardless of the DVI-D connector status.
High-Definition Multimedia Interface (HDMI)
The HDMI port supports standard, enhanced, or high-definition video, plus multichannel
digital audio on a single cable. It is compatible with all ATSC and DVB HDTV standards
and supports 8 full range channels at 24-bit/96kHz audio of lossless audio formats such
as Dolby TrueHD or DTS HD Master Audio. The maximum supported resolution is 1920
x 1200 at 60 Hz refresh (WUXGA).
The HDMI port is compliant with the HDMI 1.3 specification.
