16GB DDR4 3200 ECC RDIMM for Servers

This registered DIMM provides 16GB of error-correcting memory at 3200MHz with CL22 latency. It is built for servers and workstations that require data integrity and registered signalling. The module replaces Hynix part numbers HMA82GR7DJR4N-XN and HMAG74EXNRA086N. Verify your platform supports DDR4 RDIMMs before purchasing.

Standard voltage and registered design

Operating at 1.20V, the module follows the standard DDR4 voltage specification. The registered buffer reduces electrical load on the memory controller, aiding stability in multi-DIMM configurations. No active cooling or heat-spreader details are provided by the supplier.

Lifetime warranty and US-based support

A-Tech backs the module with a lifetime warranty and offers complimentary United States-based technical support before, during and after purchase. All units undergo quality assurance testing for dependable performance. No additional software, cables or mounting hardware are bundled.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Align the notch on the 288-pin DDR4 RDIMM with the motherboard slot key, press down firmly until both retention clips click, then verify the system BIOS registers the module at 3200 MHz with ECC active.

What maintenance or replacement will this 1Rx4 ECC RDIMM need over time?

No scheduled maintenance is required; if a correctable error count rises or the module fails POST, replace the 16 GB stick with an identical DDR4 3200 CL22 1.20 V registered DIMM.

What limit appears first when this CL22 1.20 V module runs sustained workloads?

The CAS latency of CL22 at 3200 MHz sets the timing ceiling, so sustained throughput is bounded by the 22-cycle access delay before thermal or voltage limits become factors.
