3.5 System Memory
This motherboard has two 184-pin Rambus Inline Memory Modules (RIMM) sockets.
These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM technologies.
NOTE: No hardware or BIOS setup is required after adding or removing memory.
Location Memory Module Subtotal
RIMMA1 RDRAM x 1
(Rows 0&1) C-RIMM (Use when socket will not be populated)
RIMMA2 RDRAM x1
(Rows 2&3) C-RIMM (Use when socket will not be populated)
IMPORTANT
1. The memory configuration of channel A (RIMMA1 and RIMMA2) and
channel B (RIMMB1 and RIMMB2) must be identical, (see bellow).
2. 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 make serial connection in a Rambus interface, such as
used in this motherboard. This assures that the electrical integrity of a Rambus
interface.
3. When C-RIMMs are required, it is recommended that they be inserted into
RIMMA2 and RIMMB2.
NOTE: When using only two memory
modules, it is recommended that you use
