I/O Controller Hub - ICH3

ICH3

In 2001, Intel delivered ICH3, which was available in two versions: the server version, ICH3-S, running with the E7501 Northbridge, and the mobile version, ICH3-M, which worked with the i830 and i845 northbridges. There is no version for desktop motherboards.

In comparison with the ICH2, the changes were limited: "Native Mode" support in the PATA Controller; up to six USB-1.1 devices; SMBus 2.0; and the newest SpeedStep version, which allowed power-saving devices to be switched off during operation. The chip had 421 pins.

This has the following variants:

  • 82801CA (ICH3-S) Server
  • 82801CAM (ICH3-M) Mobile
