Server DDR4 ECC RDIMM kit

This A-Tech kit supplies 64 GB of DDR4 2933 memory as two 32 GB registered DIMMs with ECC and a 1Rx4 layout. It is built for servers and workstations that require error-correcting registered modules running at 1.2 V.

Compatibility checklist

Your system must accept DDR4 288-pin RDIMMs with ECC and registered buffering; desktop and laptop platforms are not supported. Confirm the motherboard or server manual lists 2933 MHz operation, 1.2 V voltage, and single-rank x4 organisation before ordering.

Build integration

The two modules populate a dual-channel configuration to increase throughput for heavy workloads. No heat spreaders are fitted, so ensure the chassis airflow meets the server vendor’s cooling guidelines for bare modules. Registered signalling reduces electrical load on the memory controller, freeing headroom for larger memory populations.
