32GB DDR4 2666 ECC UDIMM Server Memory

This A-Tech module delivers 32GB of DDR4 2666 (PC4-21300) ECC unbuffered memory in a single 288-pin DIMM. It operates at the standard 1.20V with CL19 latency and uses a 2Rx8 rank configuration built with major brand chips. The part is a compatible equivalent for the Samsung M391A4G43MB1-CTD module.

Suited for servers and workstations needing ECC

This module fits systems that accept DDR4 2666 ECC unbuffered DIMMs and have a free 288-pin slot. It is not for platforms that require registered or load-reduced memory, nor for boards limited to non-ECC or lower-density modules. Buyers needing higher speeds, different voltages or registered DIMMs should look elsewhere.

32GB single-module capacity decides fit

The 32GB density on one stick determines whether your board and CPU memory controller support this rank and capacity per slot. Verify the maximum supported density per DIMM and the qualified vendor list for your specific server or workstation model before ordering.

Questions sur cet article

Will the CL19 latency at 2666 MHz become a bottleneck under sustained server workloads?

The module runs at CL19 with a 2666 MHz data rate, so latency is fixed at that specification for continuous operation.

Does the 1.20 V ECC UDIMM run hot or loud during all-day use?

Standard DDR4 1.20 V voltage keeps power draw low, and the unbuffered design has no active cooling to generate noise.

What motherboard slot and memory controller features are required for this 288-pin 2Rx8 module?

A DDR4 UDIMM slot with ECC support is needed; the 288-pin form factor and 2Rx8 organisation must be accepted by the platform.
