Intel Desktop Board DX58SO2/DX58OG consists of the Intel Core i7 processor and the
Intel X58 Chipset including the IOH (I/O Hub) and the ICH10R (I/O Controller Hub).
The Intel Core i7 processor integrates the system memory controller and accesses
DDR3 memory through three independent memory channels. The IOH provides
support for two PCI Express* x16 graphics slots, the PCI Express x4 slot, and connects
to the processor via the Quick Path Interconnect™ (QPI™) bus. The ICH10R provides
support for SATA, USB, and other system interfaces in addition to communicating with
the IOH via the DMI bus.
BIOS performance tuning controls include the host clock, processor turbo ratios, QPI
data rate, IOH, and processor and memory voltages. A simplified system block
diagram is shown in Figure 2.1.
