A-Tech 16GB DDR3 1866MHz ECC RDIMM 2Rx4 Server RAM

16GB DDR3 ECC RDIMM for servers

This 16GB DDR3 1866MHz ECC registered DIMM targets administrators upgrading compatible Samsung part numbers in rackmount or tower servers. The single module uses a 2Rx4 organisation and Major Brand chips to deliver registered error-correcting memory for mission-critical workloads. It operates at the standard DDR3 voltage of 1.5V with a CAS latency of CL13. Buyers needing unbuffered UDIMMs or non-ECC memory for desktop platforms cannot use this module.

240-pin registered DIMM integration

The 240-pin DDR3 DIMM slots into registered memory channels on supported server motherboards and requires a chipset that accepts ECC RDIMM topology. Registered buffering reduces electrical load on the memory controller, freeing headroom for higher total system capacities when multiple modules are populated. Systems limited to unbuffered memory or those lacking ECC support will not post with this module installed. Verify the platform qualified vendor list before installation.

Sustained load behaviour

Under continuous operation the module maintains the rated 1866MHz data rate and 1.50V supply without throttling, relying on the server chassis airflow for thermal management. ECC circuitry corrects single-bit errors on the fly, preserving data integrity during long compute runs or virtualisation workloads. The 2Rx4 rank structure presents a consistent load profile to the memory controller across extended duty cycles. Workloads demanding higher frequencies or lower latencies than CL13 will not benefit from this specification.
