Support Knowledge Base
The Intel® D50TNP module family includes one of the following server boards:
D50TNP1SB server board: 8 DDR4 DIMM slots and 4 Intel® Optane™ Persistent Memory DIMM slots, for a total of 12 DIMM slots per processor.
D50TNP1SBCR server board: 8 DDR4 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.
On the D50TNP1SB server board, channels A, C, E, and G each support two DIMM slots:
Slot 1 (blue slot for DDR4 DIMM)
Slot 2 (black slot for Intel® Optane™ Persistent Memory)
The remaining channels each support one DIMM slot (blue slot for DDR4 DIMM).
On the D50TNP1SBCR server board, all the channels each support one DIMM slot (blue slot for DDR4 DIMM).
