A-Tech 16GB (2x8GB) DDR3 1866 ECC RDIMM 2Rx4 1.5V server RAM

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.
