16GB DDR4 ECC RDIMM for servers

This 16GB DDR4 2133MHz registered DIMM delivers error-correcting memory for server and workstation platforms. The 2Rx4 organisation and CL15 latency suit workloads that demand data integrity over raw bandwidth. It replaces the listed Hynix part numbers in compatible systems.

Standard voltage and registered design

Operating at 1.20V, the module runs at the normal DDR4 voltage without extra power overhead. Registered buffering reduces electrical load on the memory controller, helping stability in populated slots. No special cooling or raised fan speeds are required for typical server chassis airflow.

Major-brand chips and lifetime support

Built with major-brand components, the stick undergoes quality-assurance testing before shipment. A-Tech backs the module with a lifetime warranty and provides US-based technical support for compatibility checks and troubleshooting. Verify your system's supported memory specifications before ordering.

Questions about this item

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

Power off the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that ECC and registered mode are detected at 2133 MHz CL15.

What maintenance or replacement will this 16GB 2Rx4 module need over its service life?

No scheduled maintenance is required; keep air paths clean so the 1.20V modules stay cool, and replace only if memory diagnostics report correctable ECC errors rising or a hard failure occurs.

What limit appears first when this CL15 2133 MHz RDIMM runs sustained workloads?

The 2133 MHz PC4-17000 bandwidth ceiling is reached before thermal throttling at 1.20V, so throughput tops out at the rated transfer rate during continuous heavy use.
