DD9400 DIMM configurations

The SP Module contains two Intel SP processors each with an integrated memory controller that supports six channels of DDR4 memory. The CPU allows two DIMM slots per channel, so the SP Module supports 24 DIMM slots.

Each DDR4 DIMM is connected to the system board through an industry standard 288-pin DDR4 DIMM connector. This system uses registered DIMMs with Dell EMC ControlCenter at 72 bits wide (64-bits data + 8-bits Dell EMC ControlCenter) up to a maximum of 2666MT/s speed.
