What this module is and who it serves

This is a 16GB DDR4 2400MHz ECC Registered RDIMM designed for Supermicro X10DRH-I, X10DRH-iT, X10DRi, X10DRi-T and X10DRL-i motherboards. It targets server, workstation and NAS builders who need registered error-correcting memory for those specific platforms.

What the registered ECC design changes

Registered buffering and ECC let the module work in multi-DIMM server configurations where unbuffered memory cannot be used. The CL17 latency and 1.2V operation match the PC4-19200 JEDEC standard for stable 2400MHz throughput in those systems.

What to verify before ordering

Confirm your motherboard is one of the five listed Supermicro models and that the memory slots accept 288-pin DDR4 RDIMMs. This module will not work in standard desktop boards and cannot be mixed with unbuffered DIMMs in the same system.

Questions about this item

Will the 288-pin DDR4 RDIMM need a heat spreader added later for continuous server duty?

The module ships without a heat spreader; its 1.2V DDR4 design runs within JEDEC thermal limits for the listed Supermicro X10 boards, so no extra cooling is required.

What limits sustained throughput on this 2400 MHz CL17 ECC registered kit?

The DDR4 2400 PC4-19200 CL17 timing and dual-rank 2Rx8 organisation set the bandwidth ceiling; the registered buffer adds one cycle but keeps signal integrity at full load.

How much power and heat does a 16 GB stick draw when the server runs all day?

At 1.2V the module draws roughly 3 W typical, producing modest heat that the chassis airflow on X10DRH-I, X10DRi or X10DRL-i boards handles without extra fan speed.
