16 GB DDR4 RDIMM for servers

This single-module kit delivers 16 GB of DDR4-2933 registered memory with ECC. It is built for servers and workstations that require error correction and signal buffering. The RDIMM form factor fits standard DDR4 server slots.

Thermals, noise and power draw

As a passive component the module produces no audible noise and adds minimal heat to the chassis airflow. Power consumption follows standard DDR4 voltage for the stated bus speed. System thermals depend on the platform and overall memory population.

ECC and registered buffering

On-die ECC detects and corrects single-bit errors to protect data integrity in critical workloads. The registered buffer reduces electrical load on the memory controller, allowing higher capacities per channel. No additional software or accessories are included.

Questions about this item

How do I install this RDIMM and which notch orientation do people get wrong?

Align the single off-centre notch on the module with the key in the DDR4 RDIMM slot, press straight down until both retention clips click, and verify the 2RX8 rank label faces the correct side per the motherboard manual.

What maintenance or replacement will this ECC module need later?

No scheduled maintenance is required; if a correctable error count climbs or the module fails POST, replace the single 16 GB stick rather than attempting repair.

What limit appears first under sustained load with this DDR4-2933 RDIMM?

The JEDEC PC4-23400 data rate caps sustained throughput, so bandwidth saturates before thermal throttling on typical server workloads.
