Server ECC RDIMM kit

This A-Tech 16 GB kit contains two 8 GB DDR3 1866 MHz registered DIMMs with ECC and a dual-rank x4 organisation. It is built for servers and workstations that require registered memory and error correction for data integrity. The modules operate at the standard 1.5 V DDR3 voltage with CL13 latency. Buyers needing desktop or laptop SODIMMs cannot use this product.

Compatibility check before ordering

Verify that your system manual lists support for DDR3 240-pin registered ECC RDIMMs at 1866 MHz and that the motherboard accepts dual-rank x4 modules. Confirm the maximum capacity per slot and the supported channel population rules for your specific platform. This kit is not compatible with standard desktop or laptop computers that use unbuffered non-ECC memory.

Thermals noise and power draw

The modules run at the standard 1.5 V DDR3 voltage without additional cooling requirements beyond normal server airflow. Registered DIMMs place less electrical load on the memory controller than unbuffered equivalents at the same capacity. No moving parts are present so the kit adds no audible noise. Power draw scales with the number of populated slots and the workload intensity.

Questions about this item

Does the kit include two 8 GB modules or do I need to buy a second stick?

The package contains two 8 GB modules for a total of 16 GB, so no additional sticks are required.

Why is the kit labelled 2Rx4 instead of a single-rank option?

2Rx4 means each module is dual-rank with x4 chip organisation, which suits servers that need higher density per DIMM slot.

Will the CL13 latency at 1866 MHz actually improve my server throughput?

CL13 at 1866 MHz reduces cycle time compared with slower DDR3 modules, helping the server handle larger workloads more responsively.
