  • DDR4 2666MHz speed delivers responsive performance
  • CL19 latency at 1.2V ensures efficient operation
  • 2Rx4 dual-rank architecture maximises memory density

Server ECC RDIMM for Workstations

This 32GB A-Tech module is a compatible replacement for the Hynix HMA84GR7MFR4N-VK and targets servers and workstations that require registered ECC memory. The single DIMM delivers 2666MHz DDR4 speed with CL19 latency at the standard 1.20V operating voltage.

288-Pin DIMM with 2Rx4 Organisation

The registered 2Rx4 layout uses major-brand chipsets and fits the standard DDR4 DIMM slot. ECC and registered buffering improve data integrity for multi-tasking workloads and higher-density configurations. Quality-assurance testing is performed on every module before it ships.

Standard-Voltage Operation for Stable Thermals

Running at 1.20V keeps power draw and heat output within normal DDR4 limits for registered server memory. The module is designed for continuous operation in environments where sustained throughput and error correction take priority over low latency.

Preguntas sobre este artículo

Does the DDR4 2666 PC4-21300 interface cap the module at 2666 MT/s in a server board?

Yes, the DDR4 2666 PC4-21300 rating means the module runs at 2666 MT/s when the platform supports that speed; it will down-clock automatically if the system only supports a lower DDR4 rate.

Will this 288-pin registered DIMM fit a standard server DIMM slot?

The module uses the 288-pin DDR4 RDIMM form factor, which matches standard server DIMM slots; verify your system accepts registered ECC memory before installing.

What is the correct way to seat the module so the ECC registration initialises?

Align the notch with the slot key, press firmly straight down until both retention clips click, then power on; the most common mistake is stopping before both clips engage, which leaves the register inactive.
