Exact-fit DDR4 ECC UDIMM kit

This 64GB kit contains four 16GB DDR4-2933 modules built to the PC4-23400 standard with CL21 timing and 1.2V operation. Each stick is a 288-pin unbuffered ECC UDIMM using 1Rx8 organisation, matching the memory controller requirements of the supported Supermicro motherboards.

Build integration and slot planning

The kit fills four UDIMM slots with the exact rank, voltage and timing the board expects, allowing the system to recognise the full capacity at rated speed. ECC function detects and corrects single-bit errors on the fly, protecting data integrity in server or workstation workloads. Builders needing a different capacity or registered DIMMs must select another kit.

Thermals and power profile

Modules run at the standard 1.2V without heat spreaders, relying on case airflow for cooling. Power draw stays within normal DDR4 limits for unbuffered ECC UDIMMs at this frequency. Audible noise is negligible as there are no moving parts on the modules themselves.

Questions about this item

Does the CL21 latency limit throughput when the memory runs continuously at DDR4-2933?

CL21 is the rated timing at DDR4-2933; the modules run at this latency continuously without throttling.

How much heat does the kit produce during all-day operation without heat spreaders?

The 1.2 V DDR4 UDIMMs generate minimal heat; standard case airflow is sufficient for sustained loads.

Which motherboard must I already have for this 4 × 16 GB ECC UDIMM kit to work?

It is validated for Supermicro X12SCZ-F and X12SCZ-TLN4F boards that accept 288-pin unbuffered ECC DDR4.
