Server DDR4 LRDIMM

This A-Tech module is a 16GB DDR4 2133 ECC LRDIMM built for server and workstation platforms that require load-reduced registered memory. The 2Rx4 organisation and 1.20V operation match the electrical profile of the Hynix HMA42GL7MFR4N-TF it replaces. Buyers who need unbuffered UDIMMs or standard RDIMMs should select a different product.

16GB capacity and CL15 timing

The single 16GB rank delivers 16GB of addressable memory per slot at PC4-17000 data rates with CAS latency 15. ECC corrects single-bit errors and detects multi-bit faults to protect data integrity in mission-critical workloads. Systems limited to lower densities per DIMM or to non-ECC memory cannot use this module.

Quality assurance and lifetime warranty

Every module undergoes A-Tech quality-assurance testing before shipment to verify reliable operation at the rated speed and voltage. A lifetime warranty covers the part for as long as you own it, and US-based technical support is available for compatibility questions before or after installation. No additional software or accessories are included.

Questions about this item

Will this DDR4 2133 CL15 LRDIMM work in a server that currently uses DDR4 2133 registered DIMMs?

No, Load Reduced DIMMs and Registered DIMMs use different buffering technology and cannot be mixed in the same memory channel.

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

Enter the system BIOS or UEFI and verify the memory speed reads 2133 MHz and the ECC status shows enabled for the new module.

Does the 16GB 288-pin LRDIMM ship alone or with additional parts such as a heat spreader?

The box contains a single 16GB DDR4 2133 CL15 ECC LRDIMM module only; no heat spreader, cables or tools are included.
