16GB DDR4 ECC RDIMM for Servers

This 16GB DDR4 2400MHz ECC registered DIMM is built for server and workstation systems that require error-correcting memory. It operates at 1.2V with a CAS latency of CL17 and uses a 1Rx4 rank configuration on a 288-pin form factor. The module is a direct replacement for specific Hynix part numbers.

Registered Buffer and ECC for Data Integrity

The registered buffer reduces electrical load on the memory controller, allowing stable operation in multi-module configurations. ECC detects and corrects single-bit errors, preventing data corruption in critical workloads. Major brand chips are used throughout, and every module undergoes quality assurance testing before shipment.

16GB Capacity for Virtualisation and Databases

A single 16GB module provides headroom for running multiple virtual machines, hosting databases, or processing large datasets in memory. Systems with limited DIMM slots benefit from the high density per module. Workloads that exceed 16GB per channel or require higher bandwidth than PC4-19200 will need additional modules or a faster memory tier.

Questions about this item

Will the registered ECC RDIMM design require any special motherboard slots or periodic firmware updates?

The module uses the standard 288-pin DDR4 DIMM form factor and operates at 1.2V, so it fits any DDR4 RDIMM slot without extra firmware.

What is the first limit reached during continuous server workloads with this CL17 2400MHz module?

Sustained throughput is capped by the DDR4-2400 data rate and CL17 latency, which set the maximum bandwidth ceiling under heavy load.

How much heat and power does a single 16GB 1Rx4 stick draw when running 24/7?

At the standard 1.2V DDR4 voltage the module draws minimal power and produces low heat, typical for registered ECC DIMMs in server environments.
