• DDR4 Data Transfer Rates:
— 2133 MT/s (PC4-2133)
— 2400 MT/s (PC4-2400)
— 2666 MT/s (PC4-2666)
• LPDDR3 Data Transfer Rates:
— 1866 MT/s
— 2133 MT/s
• SODIMM Modules:
DDR4 SODIMM/UDIMM Modules:
— Standard 4-Gb, 8-Gb technologies and addressing are supported for x8 and
x16 devices, 16-Gb technologies and addressing supported for x8 device.
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)
• LPDDR3 Memory Down: Single and Dual Rank x32/x64 (based on SKU)

Notes:
1. 1DPC refers to when only 1 DIMM slot per Channel is routed. 2DPC refers to when 2 DIMM slots per
Channel are routed and are 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. S-Processor 6+2/8+2 DDR4 2666 MT/s 2DPC UDIMM is supported when channel is populated with the
same UDIMM part number.
4. DDR4 2666 MT/s support is limited to SoDIMM raw cards versions A, C, E, D and G.
