Server-grade DDR4 ECC registered memory

This 16 GB DDR4-2666 module operates at CL19 with a 1.20 V supply. The registered signal and on-die ECC protect data integrity in multi-socket servers and workstations. A single 1Rx8 rank keeps the electrical load low for dense memory configurations. The 288-pin DIMM fits standard DDR4 slots in compatible platforms.

Thermals noise and power draw

Standard DDR4 voltage of 1.20 V keeps power consumption modest under typical server workloads. Passive operation produces no acoustic noise, relying on chassis airflow for cooling. Registered buffering reduces signal loading on the memory bus, which can lower overall system power at high DIMM counts. No active cooling components are present on the module.

Registered ECC and single-rank layout

On-board ECC corrects single-bit errors and detects multi-bit errors without software intervention. The registered clock driver improves command-address stability when many modules are populated. A single 1Rx8 rank allows more modules per channel compared to dual-rank alternatives. These traits suit virtualisation hosts and database servers that demand maximum capacity per socket.

Questions about this item

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

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify the registered ECC module is recognised in BIOS at 2666 MHz.

What maintenance or replacement will this 16 GB DDR4 ECC module need later?

No routine maintenance is required; replace only if memory diagnostics report correctable ECC errors rising above threshold or if a DIMM fails POST.

What limit appears first when this CL19 1.20 V module runs sustained workloads?

The registered buffer and CL19 latency set the throughput ceiling at 2666 MT/s, so sustained bandwidth saturates before thermal or voltage limits are reached.
