Capacity and role
This 16 GB DDR4 module provides registered ECC memory for servers and workstations that require error correction and signal buffering. The dual-rank design allows higher density per slot while maintaining the CL17 latency rating at 2400 MT/s.
Thermals and power
Operating at the standard 1.2 V DDR4 voltage, the module draws low power and generates modest heat under typical server workloads. No active cooling is included, so airflow across the DIMM area should be maintained by the system chassis fans.
Build integration
The 288-pin registered DIMM fits DDR4 RDIMM slots that support registered memory; it will not work in unbuffered consumer platforms. Each module occupies a single slot, leaving remaining channels free for additional capacity up to the platform limit.

Questions about this item
How do I install the 288-pin DDR4 module and what step is often missed?
Align the notch with the motherboard key, press firmly until both retention clips click, then verify the registered buffer is recognised in BIOS — skipping the clip check leaves the module partially seated.
What maintenance or replacement will the 16GB dual-rank ECC module need later?
No routine maintenance is required; if a correctable error count rises, replace the DIMM — ECC extends usable life but cannot repair a failed DRAM chip.
What limit appears first under sustained load with the CL17 2400MHz registered memory?
The registered buffer adds one cycle of latency, so the CL17 timing ceiling is reached before bandwidth saturates, capping sustained throughput at the rated PC4-19200 level.
