8GB DDR4 2133MHz ECC UDIMM

This A-Tech module provides 8GB of DDR4 ECC unbuffered memory for server and workstation systems. It operates at 2133MHz with a CAS latency of CL15 and a standard 1.20V voltage. The 288-pin DIMM uses a 2Rx8 rank configuration with major brand chips. It serves as a compatible replacement for the Micron MTA18ASF1G72AZ-2G1 part number.

Capacity and headroom

The single 8GB module adds memory capacity to handle larger datasets and heavier multitasking in supported platforms. ECC functionality detects and corrects single-bit errors to maintain data integrity in critical workloads. Headroom is limited to the module's rated 2133MHz speed and the maximum capacity allowed by the host system's memory slots and chipset. Systems requiring registered DIMMs or higher densities cannot use this unbuffered module.

Bundled value

The module undergoes quality assurance testing to verify reliable performance before shipment. A lifetime warranty covers the memory for the duration of ownership. United States-based technical support is available before, during, and after purchase to assist with compatibility verification and installation questions. No additional software or physical accessories are included with the module.

Questions about this item

Will this DDR4 2133 ECC UDIMM run reliably alongside other DDR4 modules already in my server?

Mixing memory speeds causes the system to run all modules at the speed of the slowest installed module, so this 2133 MHz stick will downclock to match older DDR4 DIMMs.

How can I confirm the module is operating at DDR4 2133 with ECC active after installation?

Enter the system BIOS or UEFI and verify the reported memory speed shows 2133 MT/s, the voltage reads 1.20 V, and ECC status is enabled.

Does the package contain only the 8 GB 288-pin UDIMM or are any cables or brackets included?

The box contains a single 8 GB DDR4 2133 ECC UDIMM module; no cables, brackets or additional hardware are supplied.
