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 321 and “C6220 System Board Connectors” on page 322 for the
locations of the memory modules.
Memory Slot Features
• Support 8 channels, 16 UDIMMs/RDIMMs of DDR3
• Speed up to 1866MT/s
• Max. capacity: 512GB with 32GB RDIMM, LRDIMM
• Support DDR3/DDR3L
• Support ECC
RDIMM on 1 DPC.
Supported Memory Module Configuration
For the sequence of the sixteen memory-module sockets, see Figure 3-57.
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 Ta ble 3-2 and Table 3 -3 for possible memory configurations.
