System Memory
Your system supports DDR3 registered DIMMs (RDIMMs) or ECC
unbuffered DIMMs (UDIMMs). 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 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 (two per channel) 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 cause your
system to halt at startup without any video output of system messages.
•
RDIMMs and UDIMMs cannot be mixed.
•
No more than two UDIMMs can be populated per channel.
•
Except for memory channels that are unused, all populated memory
channels must have identical configurations.
