2.5.1 Overview
This motherboard has four 184-pin Rambus Inline Memory Modules (RIMM)
sockets. These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM
technologies.

•
The memory configuration of channel A (RIMMA1 and RIMMA2)
and channel B (RIMMB1 and RIMMB2) must be identical (as
below).
•
C-RIMMs (Continuity RIMM) must be used to complete the sockets
that are not populated by RDRAMs. A C-RIMM is necessary to
avoid breaking the signal lines, which are a serial connection in a
Rambus interface, such as used in this motherboard. This assures
the electrical integrity of a Rambus interface.
•
When C-RIMMs are required, it is recommended that they be
inserted into RIMMA2 and RIMMB2.
