16GB DDR4 2666 ECC RDIMM

This 16GB DDR4 2666 registered ECC module targets administrators upgrading Dell servers or workstations that require error-correcting memory. It operates at 1.20V with CL19 latency and a 2Rx8 organisation. The 288-pin DIMM fits standard DDR4 server slots.

Major Brand Chipset and lifetime testing

Every module uses Major Brand Chips and undergoes quality-assurance testing before shipment. The registered buffer reduces electrical load on the memory controller, allowing larger populations in multi-slot systems. A-Tech backs the part with a lifetime warranty and US-based technical support.

Dell part-number cross-reference

The stick replaces Dell part numbers 370-ADOR, 370-ADNU, AA951241, 370-ADOJ, AB003149, AB011860, AA138422, NMWFP, A9810567, SNPVM51CC/16G and SNPPWR5TC/16G. Buyers who cannot verify their platform's supported memory specifications against this list should not purchase.

Questions about this item

Will the 16GB DDR4 2666 ECC RDIMM 2Rx8 CL19 module need any firmware updates or component replacements during its service life?

No firmware updates or component replacements are required; the module is a solid-state DRAM device validated at 1.20V and CL19, and A-Tech backs it with a lifetime warranty.

What is the first limit reached when this 16GB DDR4 2666 registered ECC module runs sustained workloads?

The primary limit is the 16GB capacity ceiling; once the working set exceeds 16GB the system must swap, while the 2666 MT/s data rate and CL19 latency remain constant.

How much heat and power does the 1.20V 288-pin DDR4 2666 ECC RDIMM produce during all-day operation?

The module operates at the standard DDR4 1.20V, so power draw and heat output are low and well within typical server DIMM thermal envelopes for continuous use.
