16 GB DDR4 3200 RDIMM for servers

This 16 GB registered DIMM runs at DDR4 3200 with CL22 timings and a 1.20 V operating voltage. It is built for servers and workstations that require ECC parity protection and registered signal buffering. The dual-rank 2Rx8 organisation helps maximise capacity per channel. Modules ship without a heat spreader.

Thermals and power in normal use

Operating at the standard 1.20 V DDR4 voltage keeps power draw low for high-density server configurations. The absence of a heat spreader means airflow across the DRAM is direct, so case ventilation should be adequate for typical workloads. No active cooling or fan specifications are provided for this module. Registered buffering reduces electrical loading on the memory bus.

Registered ECC parity decides fit

The module uses registered signalling with integrated ECC parity, so the motherboard must support RDIMMs and parity error correction. Systems that accept only unbuffered UDIMMs or require full ECC correction will not be compatible. Verify the platform memory qualification list before purchase.

Questions about this item

How do I install the RDIMM correctly, and which step is most often missed?

Align the notch with the motherboard key, press down evenly until both retention clips click, and verify the register chip seats fully — the clip click is the step most people skip.

What maintenance or replacement will the 16GB DDR4 3200 module need over its service life?

No scheduled maintenance is required; the module has no heat spreader and operates at 1.20 V, so replacement only occurs if a memory test reports uncorrectable ECC parity errors.

What limit appears first when the dual-rank RDIMM runs sustained workloads at CL22?

The CAS latency of 22 cycles at 3200 MHz sets the timing ceiling; thermal throttling is unlikely without a spreader, so latency remains the first bottleneck.
