Server-grade DDR5 ECC RDIMM kit

This 2 TB kit contains sixteen 128 GB DDR5-6400 registered DIMMs built to PC5-51200 timing with CL52 latency at 1.1 V. The 2Rx4 organisation and ECC registered design match the memory controller requirements of the Supermicro H14DSH motherboard so the full capacity is recognised and runs at rated speed.

Suited for fully populated H14DSH builds

The kit targets administrators who need the maximum supported memory in a single Supermicro H14DSH platform and want a single validated part number. Systems that require unbuffered UDIMMs, lower capacities or a different pin layout should select alternative memory.

Steady throughput under continuous load

Registered buffering reduces electrical load on the memory controller, allowing all sixteen slots to operate together without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during sustained workloads such as virtualisation, database serving or scientific compute.

Questions about this item

Does the Supermicro H14DSH motherboard need all sixteen DIMM slots filled for this 2TB kit to operate?

The kit provides sixteen 128 GB modules to match the board's 288-pin RDIMM slots; population order follows the motherboard manual.

Will the registered ECC design of these modules work with older unbuffered DDR5 DIMMs I might still have installed?

Registered RDIMMs and unbuffered UDIMMs cannot be mixed; the memory controller requires one type across all populated slots.

How can I verify the kit is running at DDR5-6400 with CL52 timings after installation?

Check the BIOS memory information screen or an OS tool such as dmidecode to confirm 6400 MT/s speed and 52-cycle CAS latency.
