Memory Population
The systems have eighteen DIMM slots. Each CPU controls nine slots. The DIMM slots support DDR3-
1333 registered/unbuffered ECC memory modules. For single rank and dual rank RDIMM the system
supports a maximum of 3 DIMMs per channel and a total of 18 DIMMs can be supported. For UDIMM and
quad rank RDIMM, the system supports 2 DIMMs per channel and a total of 12 DIMMs can be supported.
•
Each CPU has three memory channels (channel 1, 2 and 3).
• Each channel has 3 slots.
To maximize the memory performance, the DIMM modules should be installed as balanced as possible
among processors and memory channels. Slots with the same slot number across memory channels
should be populated with identical DIMMs.
