Asus 850 ATX 2.2System Memory, When, C-RIMMs, IMPORTANT, NOTE: No hardware or BIOS setup is required after adding or removing memory

2.HARDWARE SETUP

2.2System 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		Subtotal
RIMMA1	RDRAM	x 1
(Rows 0&1)	C-RIMM (use when socket will not be populated)
RIMMA2	RDRAM	x 1
(Rows 2&3)	C-RIMM (use when socket will not be populated)
RIMMB1	RDRAM	x 1
(Rows 4&5)	C-RIMM (use when socket will not be populated)
RIMMB2	RDRAM	x 1
(Rows 6&7)	C-RIMM (use when socket will not be populated)
	TOTAL SYSTEM MEMORY	=
	(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.
