Server ECC RDIMM Upgrade

This 16GB DDR4 module runs at 2400MHz with CL17 latency and 1.2V operation. It uses a 288-pin registered DIMM form factor with 2Rx8 organisation and on-board ECC. The kit is validated for specific Supermicro X10 motherboards including X10DRFF-C, X10DRG-O+-CPU, X10DRG-OT+-CPU, X10DRH-CLN4 and X10DRH-iLN4.

Sustained Workload Behaviour

ECC correction maintains data integrity during continuous server tasks such as virtualisation, database serving or NAS workloads. Registered buffering reduces electrical load on the memory controller, allowing stable operation when all slots are populated. The module replaces Supermicro part numbers MEMDR416LCL06ER24, MEMDR416LHL03ER24 and MEMDR416LSV01ER24.

Thermals and Power

The stick operates at the standard DDR4 1.2V without a heat spreader, relying on chassis airflow for cooling. Low voltage keeps power draw modest in multi-DIMM configurations. No active cooling is required on the module itself. This memory is not compatible with standard desktop platforms or unbuffered DIMM slots.

Perguntas sobre este artigo

Does the 1.2 V DDR4 2400 RDIMM run hotter than standard DIMMs under 24/7 server load?

No — the 1.2 V DDR4 2400 RDIMM operates at standard JEDEC voltage and has no heat spreader, so thermals match typical registered DDR4 modules.

Which motherboard must I already own for this 288-pin ECC registered kit to work?

A Supermicro X10DRFF-C, X10DRG-O+-CPU, X10DRG-OT+-CPU, X10DRH-CLN4 or X10DRH-iLN4 board with DDR4 RDIMM slots.

Can I add this CL17 2Rx8 module alongside older Supermicro MEMDR416LCL06ER24 sticks?

Yes — it replaces those exact part numbers, so matching speed, voltage, rank and ECC registered type allows mixed population.
