32GB DDR4 2666 ECC Kit for NAS and Workstations

This 32GB kit contains two 16GB unbuffered DDR4 2666 modules with ECC and a CL19 latency. It is designed for desktop PCs, workstations, servers and NAS systems that require error-correcting memory. The modules operate at the standard 1.2V JEDEC voltage.

Dual-channel 288-pin UDIMM fits standard desktop

The kit uses the 288-pin UDIMM form factor and installs in pairs to enable dual-channel operation on compatible motherboards. No heat spreader is fitted, keeping the module height low for tight clearances. Backward compatibility allows operation at 2133MHz and 2400MHz if the platform requires a lower speed.

Low-voltage ECC modules run cool and quiet

At 1.2V the modules draw minimal power and generate little heat during typical workloads. With no onboard LEDs or active cooling, the memory adds no audible noise to the system. ECC operation helps maintain data integrity without increasing thermal output.

Questions about this item

Will the CL19 latency limit throughput during long workloads?

CL19 is the rated CAS latency at DDR4 2666; sustained throughput depends on the memory controller and workload pattern rather than the module alone.

How much heat and power does the kit draw when running 24/7?

Each 16 GB module operates at 1.2 V with no heat spreader; total power scales with utilisation and the host platform's memory controller.

What must the system already support for this 288-pin ECC UDIMM kit to work?

A desktop, workstation, server or NAS board with DDR4 slots that accept 288-pin unbuffered ECC DIMMs at 2666, 2400 or 2133 MHz.
