I/O Controller Hub - ICH10

ICH10

Intel launched the ICH10 southbridge in June 2008 with the P45 (Eaglelake) chipset.

ICH10 implements the 10Gbit/s bidirectional DMI interface to the "northbridge" device. It supports various interfaces to "low-speed" peripherals, and it supports a suite of housekeeping functions.

ICH10 also offers reduced load on CPU and decreased power consumption.

ICH10 does not offer direct PATA or LPT support. Notably there is support of 'hot-swap' functionality.

The RAID variant also supports a new technology called “Turbo Memory”. This allows the use of flash memory on a motherboard for fast caching.

Peripheral support includes:

  • Six PCIe version 1.1 ports, four of which can be configured as either 4 ×1 or 1 ×4.
  • PCI bus
  • Six SATA 3 Gbit/s ports in either legacy IDE or AHCI mode. Can support external eSATA
  • Intel High Definition Audio
  • Integrated gigabit LAN.
  • Two EHCI host controllers (which support up to twelve USB 2.0 connections)

This part has the following variants:

  • 82801JB (ICH10) Base
  • 82801JR (ICH10R) RAID
  • 82801JH (ICH10D) Digital Home
  • 82801JO (ICH10DO) Digital Office
