2.5 System memory
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.

When using only two
memory modules, it is
recommended that you use
configuration a.
Location Memory Module
RIMMA1 RDRAM
(Rows 0&1) C-RIMM (use when socket will not be populated)
RIMMA2 RDRAM
(Rows 2&3) C-RIMM (use when socket will not be populated)
RIMMB1 RDRAM
(Rows 4&5) C-RIMM (use when socket will not be populated)
RIMMB2 RDRAM
(Rows 6&7) C-RIMM (use when socket will not be populated)
• 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.
