I/O Controller Hub [SEP] manufacturer
I/O Controller Hub
I/O Controller Hub (ICH) is a family of Intel southbridge microchips used to manage data communications between a CPU and a motherboard, specifically Intel chipsets based on the Intel Hub Architecture. It is designed to be paired with a second support chip known as a northbridge. As with any other southbridge, the ICH is used to connect and control peripheral devices.
As CPU speeds increased data transmission between the CPU and support chipset, the support chipset eventually emerged as a bottleneck between the
Controller Hub (PCH). The I/O Controller Hub (ICH) function is integrated into the PCH, removing the need for separate north bridge and south bridge.
Tylersburg.
The "Tylersburg" family of chipsets is for Socket LGA 1366 supporting CPUs with triple channel memory controllers. Unlike the "Ibex Peak" chipsets, The Tylersburg family of chipsets do not include the PCH, and the I/O Hub mainly provides extra PCI Express 2.0 ports. Peripheral connections are provided by I/O Controller Hub
