Available slots: 12 per processor
Category
Registered DIMM
(RDIMM)
Load Reduced DIMM
(LRDIMM)
NOTE:

Minimum one memory kit per processor must be installed.

It is recommended to install memory kits in multiples of 6 identical DIMMs for 6-channel symmetric memory configurations to
increase memory transfer speed.

Mix configurations of RDIMM and LRDIMM are not supported. Do NOT mix LRDIMM 64GB with LRDIMM 128GB.

If you install more than six times N8102-713 128GB DDR4-2666 LR Memory Kit, you require one of the following CPU Processor
codes containing an "M" (N8101-1177/-1178/-1179/-1180/-1181/-1182/-1183/-1184/-1185/-1186/-1187/-1188/-1189/-1190)
