ICH10
Intel launched the ICH10 southbridge in June 2008 with the P45 and P43 (Eaglelake) chipset.
ICH10 implements the 1 GB/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 slots, which can be configured as either 2 + (4 ×1) or 2 + (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
- AHCI support
- Two EHCI host controllers (which support up to twelve USB 2.0 connections) with companion UHCI controllers to handle low-speed and full-speed USB devices
This part has the following variants:
- 82801JB (ICH10) Base
- 82801JR (ICH10R) RAID
- 82801JH (ICH10D) Digital Home
- 82801JO (ICH10DO) Digital Office
