System Memory

Your system supports DDR3 registered memory modules (RDIMMs) or ECC
unbuffered memory modules (UDIMMs). Single and dual-rank memory
modules can be 1067- or 1333-MHz, and quad-rank memory modules can be
800-MHz and 1067-MHz.
The system contains eighteen memory sockets split into two sets of nine
sockets, one set per each processor. Each nine-socket set is organized into
three DIMMs for each channel. The first socket of each channel is marked
with white release levers.
The maximum memory that is supported on your system varies according to
the types and sizes of memory modules being used:
• Single-rank and dual-rank RDIMMs of sizes 2-GB, 4-GB, and 8-GB
(when available) are supported for a total of up to 144 GB.
• Quad-rank RDIMMs are supported for a total of up to 96 GB.
• 1-GB and 2-GB UDIMMs are supported for a total of up to 24 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 or producing any video output.
• RDIMMs and UDIMMs cannot be mixed.
• Except for memory channels that are unused, all populated memory
channels must have identical configurations.
• In a dual-processor configuration, the memory configuration for each
processor must be identical.
• Memory modules of different sizes can be mixed within a memory channel
(for example, 2-GB and 4-GB), but all populated channels must have
identical configurations.
