16GB DDR4 ECC RDIMM for Dell Servers

This 16GB DDR4 2666MHz registered DIMM is built for Dell server and workstation platforms that require ECC memory. It operates at 1.20V with CL19 latency and uses a 2Rx8 organisation. The module replaces Dell part numbers including 370-ADND and AA174381 for direct compatibility. Buyers needing non-ECC UDIMMs or higher-speed modules should look elsewhere.

Sustained Load Stability

Registered buffering and ECC correction maintain data integrity during continuous multi-threaded workloads typical of virtualisation or database tasks. The 2666MHz PC4-21300 rating delivers consistent throughput without the voltage overhead of faster bins. Major-brand chips are tested to ensure dependable performance over long operating periods. Systems limited to lower memory speeds will downclock this module automatically.

288-Pin Build Quality

The standard 288-pin DIMM form factor fits registered DDR4 slots in compatible Dell chassis. Registered signalling reduces electrical load on the memory controller when multiple modules are populated. Major-brand chipsets and A-Tech's quality-assurance testing support reliable daily operation in rack or tower deployments. Confirm your platform's maximum supported capacity and rank limits before ordering.

Questions about this item

How much power does the 1.2V DDR4 2666MHz module draw during continuous server workloads?

The module runs at the standard DDR4 voltage of 1.2V. Actual power draw depends on the server platform and workload, so consult your system documentation for precise figures.

What motherboard slot and CPU memory controller are required for this 288-pin ECC RDIMM?

This module needs a DDR4 288-pin DIMM slot with registered ECC support. The CPU and chipset must also support registered ECC DDR4 memory.

Can this 2Rx8 CL19 registered module share channels with existing 1Rx4 or CL17 sticks in a Dell server?

Mixing ranks, latencies or registered/unregistered modules is not recommended. For stable operation, populate all channels with identical 2Rx8 CL19 registered modules.
