A-Tech 32GB DDR4 2666 ECC LRDIMM

This 32GB DDR4 2666 module is an ECC Load Reduced DIMM built for registered server and workstation platforms. It operates at 1.2V with a CL19 latency and a 2Rx4 rank configuration across 288 pins. The module is not compatible with desktop or laptop computers.

Sustained load behaviour with LRDIMM design

The load reduced architecture buffers the data and address buses to lower the electrical load on the memory controller. This allows the 2Rx4 dual rank x4 organisation to maintain stable throughput at DDR4 2666 speeds during extended workloads. ECC protection corrects single-bit errors without interrupting operation.

Thermals noise and power at 1.2V

Standard DDR4 1.2V operation keeps power draw modest for a 32GB registered module. Passive cooling via server airflow is sufficient because the LRDIMM buffer reduces signal drive current. No active cooling or additional voltage is required for normal use.

Questions about this item

How much power does the 32 GB 2666 MHz LRDIMM draw at 1.2 V under continuous server workloads?

The module operates at the standard DDR4 voltage of 1.2 V; actual power draw depends on the platform's memory controller and workload intensity.

What must the system already provide for this 288-pin ECC LRDIMM to function?

A DDR4 server or workstation motherboard with LRDIMM-capable memory slots and a processor memory controller that supports ECC load-reduced modules.

Will this dual-rank x4 LRDIMM operate in a system that still uses single-rank registered DDR4 DIMMs in other slots?

Mixing LRDIMMs with standard registered DIMMs is not supported; the memory controller requires all populated slots to use the same load-reduced technology.
