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.
PCI Express x16 Graphics
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors in an
LGA1155 socket support discrete add in graphics cards through the PCI Express 3.0 x16
graphics connector:
 Supports PCI Express GEN3 frequency of 2.5 GHz resulting in 8.0 Gb/s each
direction (1000 MB/s) per lane. Maximum theoretical bandwidth on interface is
16GB/s in each direction, simultaneously, when operating in x16 mode.
 Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each
direction (500 MB/s) per lane. Maximum theoretical bandwidth on interface is 8GB/s
in each direction, simultaneously, when operating in x16 mode.
 Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (250 MB/s) per lane. Maximum theoretical bandwidth on interface is 4GB/s
in each direction, simultaneously, when operating in x16 mode.
