ICH7
The ICH7 started to ship in mid-2005 together with Intel's new high-end MCH, the i955X. Two additional PCI express ×1-Ports, an accelerated SATA Controller for up to 300 MB/s data transmission rate (the mobile version has this capability disabled), as well as support for Intel's "Active Management Technology" were added. Only the ICH7DH, ICH7R, ICH7-M, ICH7-M DH chip have AHCI support. The ICH7 (Base) and ICH7-U (Ultra-mobile) chip do not support AHCI.
The ICH7R additionally supports RAID 5.
This has the following variants:
- 82801GB (ICH7) Base
- 82801GR (ICH7R) RAID
- 82801GDH (ICH7DH) Digital Home
- 82801GBM (ICH7M) Mobile
- 82801GHM (ICH7M DH) Mobile Digital Home
- PC82801GU (ICH7-U) Ultra-mobile
