System Memory - Asus 850E - P4 ATX 533MHzFSB USB2 LAN User Manual

3. HARDWARE SETUP

3.4 System Memory

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard has four 184-pin Rambus Inline Memory Modules (RIMM) sockets.
These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM technologies.
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)

(2GB Max)
IMPORTANT
1. The memory configuration of channel A (RIMMA1 and RIMMA2) and chan-
nel B (RIMMB1 and RIMMB2) must be identical (see below).
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 are a serial connection in a Rambus interface, such as
used in this motherboard. This assures the electrical integrity of a Rambus
interface.
3. When C-RIMMs are required, it is recommended that they be inserted into
RIMMA2 and RIMMB2.
