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

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. 

 

PCI Express technology 

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
