Pci Express X16 Graphics; Usb; Dvi Port Status Conditions - Intel BLKDH57DD Technical Product Specification

1.7.1.3 Digital Visual Interface (DVI-I)
The DVI-I port supports both digital and analog DVI displays. The maximum
supported resolution is 1900 x 1200 (WUXGA). The DVI port is compliant with the
DVI 1.0 specification. DVI analog output can also be converted to VGA using a
DVI-VGA converter.
Depending on the type of add-in card installed in the PCI Express x16 connector, the
DVI port will behave as described in Table 5.

Note: DVI analog output can also be converted to VGA with a DVI-VGA converter.
1.7.1.3.1 Analog Display (VGA)
The VGA port supports analog displays. The maximum supported resolution is 2048 x
1536 (QXGA).
The VGA port is enabled for POST whenever a monitor is attached, regardless of the
HDMI and DVI-I connector status.

PCI Express x16 Graphics

The Intel Core i7, Intel Core i5, Intel Core i3, Intel Pentium processors, and Intel Xeon
processor 3400 series processors in an LGA1156 socket support discrete add in
graphics cards via the PCI Express 2.0 x16 graphics connector:
• 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
8 GB/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
4 GB/s in each direction, simultaneously, when operating in x16 mode.
1.8

USB

The board supports up to fourteen USB 2.0 ports through two EHCI host controllers on
the PCH that allow the use of EHCI-compatible drivers.
The port arrangement is as follows:
• Six ports are implemented with stacked back panel connectors
• Eight front panel ports are implemented with four dual-port internal headers
