16GB DDR4 2133 ECC RDIMM for servers

This 16GB registered DIMM runs at DDR4 2133 (PC4-17000) with CL15 latency and 1.20V operation. It uses a 1Rx4 organisation and major-brand chips to deliver error-correcting memory for server and workstation platforms that require registered modules. The 288-pin form factor matches standard DDR4 DIMM slots in compatible systems.

Thermals noise and power at 1.20V

Operating at the standard DDR4 voltage of 1.20V keeps power draw low and reduces heat output in densely populated memory channels. Registered buffering adds minimal electrical load while improving signal integrity across multiple modules. Passive cooling in typical server airflow is sufficient for normal workloads.

Quality testing and lifetime warranty

Every module undergoes quality assurance testing to verify reliable operation before shipment. The package includes a single 16GB stick with no additional cables, software or mounting hardware. A lifetime warranty and US-based technical support provide long-term service coverage for the memory itself.

Questions about this item

How is the 288-pin DDR4 RDIMM installed and which orientation step is often missed?

Align the notch on the module with the key in the slot, press firmly until both side clips click shut, and verify the registered module seats fully in the server board.

What maintenance or replacement will the 16GB ECC module need over its service life?

No routine maintenance is required; the module either passes POST and runs error-free or is replaced under the lifetime warranty if a correctable ECC error threshold is exceeded.

What limit appears first when the 1Rx4 registered DIMM runs at 2133 MHz under sustained load?

The CL15 latency at 1.20 V sets the timing ceiling; sustained throughput is bounded by the PC4-17000 data rate rather than thermal throttling.
