A-Tech 64GB DDR4 2666 ECC RDIMM CL19 2S2Rx4 Server Memory

64GB DDR4 ECC RDIMM for Servers

This module delivers 64GB of DDR4 2666 memory in a single 288-pin registered DIMM. It targets administrators upgrading compatible server or workstation platforms that require ECC error correction and registered signalling. The 2S2Rx4 organisation provides four logical ranks per module for dense capacity scaling.

1.20V operation with registered buffering

At the standard DDR4 voltage of 1.20V the module runs within normal server power envelopes. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity in multi-DIMM configurations. ECC circuitry corrects single-bit errors without interrupting workloads.

Sustained load stability with CL19 timing

CAS latency of 19 cycles supports consistent throughput during extended compute or virtualisation tasks. The registered design and ECC function work together to preserve data accuracy over long periods. Major-brand chipsets underpin the reliability expected in always-on environments.
