Memory sockets must be upgraded in matched pairs. In other words,

two sockets in a pair must contain modules of identical capacity,

number of components, and speed. See "

System Board Memory

Components

" to identify pairs of sockets.

Mixed pairs of

ECC

and non-ECC modules all function as non-ECC.

Be sure to install a RIMM in socket 1 first (closest to the processor)

before installing modules in the other sockets.

The system board supports PC600 and PC800 memory modules.

Riser Board Installation

When installing memory modules using the optional memory riser boards,
observe the following guidelines:

The memory riser boards must be installed in system board memory

sockets 1 and 2. Memory riser board A must be installed in system

board memory socket 1, and riser board B must be installed in system

board socket 2. System board memory sockets 3 and 4 can either be

empty or contain CRIMMs. Sockets 3 and 4 cannot contain RIMMs

with memory riser boards installed in sockets 1 and 2. See "

System

Board Memory Components

" to identify the system board sockets.

Memory sockets on the riser boards must be upgraded in matched

pairs. In other words, two sockets in a pair must contain modules of

identical capacity, number of components, and speed. See "

Memory

Riser Board Components

" to identify pairs of sockets.

Not all memory sockets on the memory riser boards need to be

populated: if one or more pairs of memory sockets contain RIMMs,

then the next pair must contain CRIMMs, and the remaining pair(s)

can be empty. For example, if the first and second pairs of memory

sockets on the riser boards contain RIMMs, then the third pair must

contain CRIMMs, and the fourth pair can remain empty.

Mixed pairs of ECC and non-ECC modules all function as non-ECC.

The optional memory riser boards only support PC800 memory

modules.
