If you intend to install 4 single-side memory modules into the DI MM slots, please note
that, the mainboard will support up to DDR 3 1066 speed only.
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium 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 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 DIMM speeds 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
DIMM is installed or the memory capacities are unequal. Technology and device
width can vary from one channel to the other. If different DIMM speeds are used
between channels, the slowest memory timing will be used.
Graphics Subsystem
The board supports system graphics through either Intel Graphics Technology or a
PCI Express 2.0 x1 add-in graphics card.
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, DVI-D, HDMI. Also, during the
Power On Self Test (POST), the board will not output to the HDMI if VGA and DVI-D is
used concurrently with 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.
Digital Visual Interface (DVI-D)
The DVI-D port supports only digital DVI displays. The maximum supported resolution is
2048 x 1536 at 75 Hz refresh (QXGA). The DVI-D port is compliant with the DVI 1.0
specification.
