Intel Desktop Board DP43BF Product Guide Intel® P43 Express Chipset The Intel P43 Express Chipset consists of the following devices: • Intel P43 Express Chipset Memory Controller Hub (MCH) with Direct Media Interface (DMI) • Intel 82801JIR I/O Controller Hub (ICH10R) with DMI The MCH component provides interfaces to the processor, memory, PCI Express, and the DMI interconnect. ICH10R is a centralized controller for the board's I/O paths. For more information on the Intel P43 Express Chipset go to http://developer.intel.com/products/chipsets/ Graphics Support Intel Desktop Board DP43BF provides graphics support through the PCI Express x16, PCI Express x1, and PCI add-in card connectors. The PCI Express 2.0 x16 interface provides the following support: • Supports the PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction (500 MB/s total). The maximum theoretical bandwidth on the interface is 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when operating in x16 mode. • Supports the PCI Express 2.0 frequency of 2.5 GHz resulting in 5.0 Gb/s each direction (1000 MB/s total). The maximum theoretical bandwidth on the interface is 8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when operating in x16 mode.
