2.1. Architecture

The Intel Desktop Board DP55KG/DP55SB platform consists of an Intel Core i7-800 or
Intel Core i5-700 processor series and the Intel
P55 Platform Controller Hub (PCH). For a detailed description of the complete platform, refer to
the Intel Desktop Board DP55KG Technical Product Specification or the Intel Desktop Board
DP55SB Technical Product Specification available at
http://www.intel.com/products/desktop/motherboard.
The processor now integrates the system memory controller and accesses DDR3 memory
through two independent memory channels. The processor also provides support for one full
PCI Express* 2.0 x16 graphics slot or switches to two PCI Express 2.0 x8 slots. The processor
connects to the PCH via the Direct Media Interface (DMI) interconnect bus. The PCH provides
support for SATA (3.0 Gb/s), USB 2.0, and other system interfaces. Figure 2 shows a block
diagram of the Intel Desktop Board DP55KG/DP55SB platform.
