2 TB DDR5 ECC RDIMM kit

This 2 TB kit contains sixteen 128 GB DDR5 registered DIMMs rated at 5600 MT/s with CL46 latency. It is built for the Supermicro H14DSH motherboard and targets administrators who need maximum registered ECC capacity in a single validated package.

DDR5 registered limits

DDR5 registered modules shift electrical load from the memory controller to the onboard register, allowing full population of every slot at the rated 5600 MT/s speed. The 1.1 V operating voltage is fixed by the DDR5 RDIMM standard, so the kit cannot run at lower voltages or at speeds the platform does not officially support.

Build and daily handling

Each module uses a bare 288-pin PCB without a heat spreader, relying on server chassis airflow for cooling. The 2Rx4 organisation and registered buffer mean the DIMMs must be installed in the exact population sequence the H14DSH manual specifies; incorrect order will prevent the system from recognising the full 2 TB capacity.

Questions about this item

Should I choose the 16 x 128 GB kit or a smaller capacity for my Supermicro H14DSH?

The 16 x 128 GB kit delivers the full 2 TB capacity this board supports when every DIMM slot is populated with registered ECC modules.

What does the DDR5 5600 CL46 rating mean once the modules are installed?

The memory controller will run each module at 5600 MT/s with a CAS latency of 46 cycles at the standard 1.1 V, giving the rated PC5-44800 bandwidth.

How does the 288-pin RDIMM interface and registered design affect real-world limits?

The registered architecture buffers address and command signals so all 16 slots can run at the full 5600 MT/s without signal degradation.
