A-Tech 64GB (2x32GB) DDR4 2666 ECC SODIMM CL19 1.2V laptop RAM

64GB ECC SODIMM kit for servers and workstations

This dual-channel kit contains two 32GB DDR4 2666 SO-DIMM modules with ECC unbuffered operation. It targets micro-servers, mobile workstations and NAS appliances that require error-correcting memory in the 260-pin form factor. Buyers whose platforms only accept non-ECC SODIMMs cannot use this kit.

64GB capacity at DDR4 2666 with CL19 latency

The 64GB total (2 x 32GB) provides ample headroom for virtualisation, large datasets and heavy multitasking on supported DDR4 systems. Each module runs at 2666 MHz (PC4-21300) with a CAS latency of 19 at the standard 1.2V JEDEC voltage. Workloads that exceed 64GB or demand higher memory bandwidth will outgrow this configuration.

Low-voltage unbuffered ECC modules without heat

Operating at 1.2V, the dual-rank 2Rx8 modules draw minimal power and generate modest heat in typical server or workstation chassis. The absence of heat spreaders keeps the profile thin for dense slot spacing, relying on system airflow for cooling. Acoustic impact is negligible because the modules have no moving parts.
