Architecture

Intel Desktop Board DP67BG consists of the 2
and the Intel P67 Express Chipset (the Platform Controller Hub (Intel P67 PCH)). The
nd
2 generation Intel Core processor family integrates the system memory controller
and the PCI Express* x16 interface. DDR3 memory is accessed through two
independent memory channels. A system clock that drives all Desktop Board
components is integrated into the Intel P67 PCH. The Intel P67 PCH provides support
for a PCI Express x1 interface, a PCI* bus, SATA, USB, and other system interfaces.
The Intel P67 PCH communicates with the processor via the DMI bus. BIOS
performance tuning controls include processor turbo ratios, the system clock, and
processor and memory voltages. A simplified system block diagram is shown in
Figure 2.1.
