Desktop Board Features VGA Displays The DVI-I port supports VGA displays when a DVI-I to VGA converter is used. The maximum supported resolution is 2560 x 1600 (WQXGA). The DVI-A port is enabled for the POST whenever a monitor is attached. 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 via the PCI Express 2.0 x16 add-in card connector. The board supports the following PCI Express speeds: • PCI Express 2 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 1.1 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 ALC892 audio codec as well as through the HDMI interface. The Realtek ALC892-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 • Stereo input and output via back panel connectors • Headphone and Mic in functions for front panel audio connectors • 97 dB Signal-to-Noise ratio (SNR) playback (DAC) quality and 90 dB SNR recording (ADC) quality • Content protection for full-rate loss-less DVD Audio and Blu-ray Disc* audio content playback (with selected versions of media player software) The audio subsystem supports the following audio interfaces: • 7.1 analog back panel audio connectors • Optical S/PDIF-out back panel audio connector • S/PDIF-out header with support for optical or coaxial S/PDIF output • Front panel audio header with support for Intel HD Audio and AC '97 Audio Table 3 lists the supported functions of the front panel (FP) and back panel (BP) audio jacks. 17

VGA Displays
The DVI-I port supports VGA displays when a DVI-I to VGA converter is used.
The
maximum supported resolution is 2560 x 1600 (WQXGA).
The DVI-A port is enabled for the POST whenever a monitor is attached.
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 via the PCI Express 2.0 x16
add-in card connector.
The board supports the following PCI Express speeds:
•
PCI Express 2 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 1.1 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 ALC892 audio codec
as well as through the HDMI interface.
The Realtek ALC892-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
•
Stereo input and output via back panel connectors
•
Headphone and Mic in functions for front panel audio connectors
•
97 dB Signal-to-Noise ratio (SNR) playback (DAC) quality and 90 dB SNR recording
(ADC) quality
•
Content protection for full-rate loss-less DVD Audio and Blu-ray Disc* audio
content playback (with selected versions of media player software)
The audio subsystem supports the following audio interfaces:
•
7.1 analog back panel audio connectors
•
Optical S/PDIF-out back panel audio connector
•
S/PDIF-out header with support for optical or coaxial S/PDIF output
•
Front panel audio header with support for Intel HD Audio and AC ’97 Audio
Table 3 lists the supported functions of the front panel (FP) and back panel (BP) audio
jacks.
