Overview
1.1.
System Architecture
The ‘Expansion’ channel is the interconnect between the MCH and the MRH-R. The MRH-R component
provides the capability to support multiple Direct RDRAM channels off each ‘expansion’ channel of a
MCH.
As an example, the Intel
82840 MCH supports one MRH-R on each of its ‘expansion’ channel buses for
a maximum of two MRH-Rs in an Intel
840 chipset system memory array.
Note:
Future Intel chipsets will support the MRH-Rs as well.

840 memory subsystem using two MRH-Rs per ‘expansion’
channel to support four Direct RDRAM Channels.
