Server memory upgrade for ECC workloads

This A-Tech module adds 16GB of DDR4 2933 ECC RDIMM capacity to compatible servers and workstations. Registered buffering and 2Rx8 organisation help maintain signal integrity on multi-DIMM channels. The CL21 latency and 1.20V operation match standard DDR4 specifications for enterprise platforms. It is sold as a single 288-pin DIMM for straightforward installation.

Replaces Micron MTA18ASF2G72PDZ-2G9 in qualified

The module is built as a compatible equivalent for that Micron part number, using major-brand chips and full quality-assurance testing. The upgrade is worthwhile when the platform supports DDR4 2933 registered ECC memory and the workload demands additional capacity or replacement of a failed stick. Verify the system's qualified-vendor list before purchase to ensure the memory controller accepts this configuration. It will not fit platforms that require unbuffered or non-ECC DIMMs.

Sustained operation at rated speed and voltage

Under continuous load the module runs at the specified 2933 MT/s and 1.20V without exceeding standard DDR4 thermal limits. Registered signalling reduces electrical loading on the memory bus, helping stability during extended multi-threaded or virtualisation workloads. ECC correction handles single-bit errors transparently, preventing data corruption over long uptimes. Performance scales with the number of populated channels as defined by the platform architecture.

Questions about this item

What 288-pin DIMM slot and 1.20V power does this DDR4 2933 module require?

It fits a standard DDR4 288-pin RDIMM slot and runs at the DDR4 standard 1.20V; the motherboard must support registered ECC memory.

Which orientation notch and seating pressure should I use when installing this 2Rx8 RDIMM?

Align the single key notch with the slot ridge, press straight down until both side clips click — do not rock the module or force one end first.

When should I expect to replace this 16GB ECC RDIMM under normal server use?

The module carries a lifetime warranty; with adequate airflow and ECC error logging it typically lasts the useful life of the server platform.
