Digital Visual Interface (DVI-D)
The DVI-D port supports digital DVI displays. The maximum supported resolution is
1920 x 1200 at 60 Hz refresh (WUXGA). The DVI-D port is compliant with the DVI 1.0
specification.
The DVI-D port is only enabled for POST when there is no monitor attached to the VGA
connector.
PCI Express* x16 Graphics
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors in an
LGA1156 socket support discrete add-in graphics cards via the PCI Express 2.0 x16
add-in card connector. The board supports the following PCI Express speeds:
• PCI Express GEN2 frequency of 2.5 GHz which results in 5.0 Gb/s in each direction
(500 MB/s) per lane. The maximum theoretical bandwidth on the interface is
8 GB/s in each direction, simultaneously, when operating in x16 mode.
• PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction
(250 MB/s) per lane. The maximum theoretical bandwidth on the interface is
4 GB/s in each direction, simultaneously, when operating in x16 mode.
Audio Subsystem
The board supports Intel High Definition Audio through a Realtek ALC888S audio
codec.
The Realtek ALC888S-based audio subsystem provides the following features:
• Advanced jack sense for the back panel audio connectors that enables the audio
codec to recognize the device that is connected to an audio port. The back panel
audio connectors are capable of retasking according to the user’s definition, or can
be automatically switched depending on the recognized device type.
• Stereo input and output via back panel connectors
• Headphone and Mic in functions for front panel audio connectors
• A signal-to-noise (S/N) ratio of 90 dB
The board provides onboard audio headers and back panel connectors.
