x4000 8-RIMM Memory Expander Card
The eight-RIMM MEC uses two memory repeater hubs for RDRAM
(MRH-R). Each MRH-R supports two Direct RDRAM channels with two
RIMMs per channel. The Memory Controller Hub (MCH) interfaces to
the MEC using an expansion channel for each MRH-R. The MEC
supports 400 MHz operation delivering up to 3.2 GB/s memory
bandwidth using two expansion channels operating in lock step. The
expansion channel is a super set of the Direct RDRAM channel using an
additional two Rambus Signaling Levels (RSL) to communicate channel
and control information from the MCH to the MRH-R. The RDRAM
memory interface can achieve greater than 95% use of the maximum
bandwidth.
