Installing System Components 63

System Memory

Your system supports DDR3 registered DIMMs (RDIMMs). Single and

dual-rank DIMMs can be 1067 or 1333 MHz, and quad-rank DIMMs can

be 1067 MHz.

The system contains 18 memory sockets split into two sets of nine sockets,

one set for each processor. Each nine-socket set is organized into three

channels of three memory sockets per channel.

The maximum memory that is supported on your system varies according to

the types and sizes of memory modules being used:

• Single-rank, dual-rank, and quad-rank RDIMMs of sizes 1 GB, 2 GB,

4 GB, and 8 GB are supported for a total of up to 144 GB.

• Quad-rank RDIMMs (two per channel) are supported for a total of

up to 96 GB.

General Memory Module Installation Guidelines

To ensure optimal performance of your system, observe the following general

guidelines when configuring your system memory.

NOTE: Memory configurations that fail to observe these guidelines can prevent

your system from starting and producing any video output.

• Except for memory channels that are unused, all populated memory

channels must have identical configurations.

• The memory configuration for each processor must be identical.

• Memory modules of different sizes can be mixed in A1–A4 or B1–B4

(for example, 2 GB and 4 GB), but all populated channels must have

identical configurations.

• For optimizer mode, memory modules are installed in the numeric order of

the sockets beginning with A1 or B1.

• For memory mirroring or advanced ECC mode, the two channels furthest

from the processor are unused and memory modules are installed

beginning with channel A1 or B1 and proceeding with channel A2 or B2.

• Advanced ECC mode requires memory modules that use x4 or x8 DRAM

device widths.
