Product Description 1.7.1.3 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 are no monitors attached to the VGA or HDMI connectors. 1.7.2 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 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. For information about PCI Express technology Refer to http://www.pcisig.com 1.8 USB The board supports up to twelve 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 via stacked back panel connectors • Six front panel ports via three dual-port internal headers; one header supports an Intel Z-U130 USB Solid-State Drive (or compatible device) For information about The location of the USB connectors on the back panel The location of the front panel USB headers Refer to Figure 9, page 38 Figure 10, page 39 19
