System Memory

Each system board has sixteen DDR3 memory module sockets for the
installation of up to sixteen unbuffered or registered DDR3-1333MHz
(1600MHz @2 memory modules per channel) memory modules to support
processor 1 and processor 2. See "C6220 II System Board Connectors" on
page 325 and "C6220 System Board Connectors" on page 326 for the
locations of the memory modules.

Memory Slot Features


Max. capacity: 512GB with 32GB RDIMM, LRDIMM



Support ECC
NOTE: To operate under 1866MT/s requires Xeon E5-2600 v2 processor with 1.5v
RDIMM on 1 DPC.
Note: Linux operating system does not support the S4 (hibernation) mode.

Supported Memory Module Configuration

For the sequence of the sixteen memory-module sockets, see Figure 3-63.
The system requires at least one memory module installed on processor 1's
DIMM slot 1 in order to be booted up. When you insert the memory
module(s), always start with CHA_A1. The optimized memory module
installation sequence is 1/2/3/4/5/6/7/8.
See Table 3-2 and Table 3-3 for possible memory configurations.
