Intel® Desktop Board DH61CR Product Guide

Intel Desktop Board DH61CR Product Guide
Graphics Subsystem
16
The board supports either integrated graphics (Intel Graphics Technology) or PCI
Express 2.0 x16 graphics.
Integrated Graphics
The board supports integrated graphics through the Intel ® Flexible Display Interface
(Intel ® FDI) for processors with Intel Graphics Technology.
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
Intel Desktop Board DH61CR supports Digital Visual Interface (DVI) displays with a
DVI-D back panel port.
The DVI-D port supports only digital DVI displays. The maximum supported resolution
is 2048 x 1536 at a 75 Hz refresh rate (QXGA). The DVI-D port is compliant with the
DVI 1.0 specification.
PCI Express* x16 Graphics
Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors in an LGA1155
package 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 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.
