Interfaces
• DDR4 Data Transfer Rates:
— 2133 MT/s (PC4-2133)
— 2400 MT/s (PC4-2400)
— 2666 MT/s (PC4-2666)
• UDIMM Modules:
DDR4 SODIMM/UDIMM Modules:
— Standard 4-Gb and 8-Gb technologies and addressing are supported for x8 and
x16 devices.
There is no support for memory modules with different technologies or capacities
on opposite sides of the same memory module. If one side of a memory module is
populated, the other side is either identical or empty.
• DDR4 Memory Down: Single rank x8, x16 (based on SKU)
2.1.1.1 DDR4 Supported Memory Modules and Devices
Notes:
1. 1DPC-refer to 1 DIMM per channel natively, means 1 DIMM Slot per channel and not refer to 1
DIMM populated at 2 DIMMs per channel.
2DPC-refer to 2DIMMs per channel, fully populated or partially populated with 1 DIMM only.
2. S-Processor SO-DIMM 2DPC is limited to 2133 MT/s due to Daisy Chain topology.
3. DDR4 SODIMM 2666 MT/s is currently NOT POR, DDR4 SODIMM 2666MT/s enabling is pending
silicon validation completion.
4. S-Processor 6+2 DDR4 2666 MT/s 2DPC UDIMM is supported when channel is populated with the
same UDIMM part number.
5. DDR4 2666 MT/s support is limited to raw card versions A, C, E, D and G.
