Memory Subsystem Architecture and Supported Memory Types for Intel® Server Board D40AMP





The Intel® Server Board D40AMP Family includes 8 DDR4 DIMM slots and 4 Intel® Optane™ Persistent Memory DIMM slots, for a total of 12 DIMM slots per processor.

Each 3rd Generation Intel® Xeon® Scalable processor supports eight memory channels using four integrated memory controllers (IMCs). Each memory channel is assigned an identifying letter A-H. Channels A, C, E, and G each support two DIMM slots—slot 1 (blue slot for DDR4 DIMM) and slot 2 (black slot for Intel® Optane™ Persistent Memory). The remaining channels each support one DIMM slot (blue slot for DDR4 DIMM).
