Installing Dcpmm Memory Modules - Supermicro X11OP Series User Manual

2.2 Installing DCPMM Memory Modules

Important: Exercise extreme care when installing or removing DIMM modules to pre-
vent any possible damage.
Memory Population Requirements
For proper memory installation, please pay close attention to the following instructions:
1. Intel 1st Generation DCPMM is supported by Supermicro X11OPx, X11QPx, X11DPx,
X11SPx series motherboards.
2. Memory speeds are dependent upon the processors used in your system.
3. All DCPMMs installed on your motherboard must be of the same size, and the DDR4
DIMMs that are installed in conjunction with DCPMMs must be of the same size and the
same type as well.
4. When installing a memory module, be sure to install the DIMM module in the first
channel slot (i.e. DIMMA1), and then, in the second channel slot (i.e. DIMMA2).
5. Please use balanced configuration to achieve maximum performance. Supermicro
does not recommend unbalanced memory configuration since it will reduce memory
performance.
6. Mixing different DIMM types or using 1Rx8 DIMMs in conjunction with DCPMMs is not
supported.
7. A total of six DCPMMs can be supported per processor (one in each memory channel),
and a minimum of two DDR4 DIMMs are required per processor (one per memory
controller).
8. For Memory Mode, a minimum of two DCPMMs are required per processor (one per
memory controller). For App Direct Mode, a minimum of one DCPMM is required per
processor (any processor).
9. Check the Supermicro website for recommended memory modules.
