Intel Desktop Board DP67DE Product Guide
Graphics Support
The board supports system graphics through a PCI Express 2.0 x16 add-in graphics
card.
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.
