P43 Express Chipset
The Intel P43 Express chipset consists of the following devices:
• Intel 82P43 Memory Controller Hub (MCH) with Direct Media Interface (DMI)
interconnect
• Intel 82801JIR I/O Controller Hub (ICH10R)
The MCH component provides interfaces to the CPU, memory, PCI Express, and the
DMI interconnect. The ICH10R is a centralized controller for the board’s I/O paths.
The chipset supports the following features:
• USB
• Serial ATA
• Parallel ATA

1.6.1.1 PCI Express x16 Graphics
The MCH also supports an add-in discrete graphics card through the PCI Express 2.0
graphics connector.
• PCI Express 2.0 x16:
⎯ Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (500 MB/s total). Maximum theoretical bandwidth on interface of
4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when
operating in x16 mode.
⎯ Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each
direction (1000 MB/s total). Maximum theoretical bandwidth on interface of
8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when
operating in x16 mode.

1.6.2 USB
The board supports up to twelve USB 2.0 ports, supports UHCI and EHCI, and uses
UHCI- and EHCI-compatible drivers.
The Intel ICH10R provides the USB controller for all ports. The port arrangement is as
follows:
• Six ports are implemented with stacked back panel connectors
• Six ports are routed to three separate front panel USB headers
