8GB DDR4 2666 ECC RDIMM kit

This 8GB kit contains two 4GB registered DIMMs built for DDR4 servers and workstations that require ECC memory. Each module runs at 2666 MHz with CL19 latency at 1.2V and uses a single-rank x8 organisation. The registered buffer reduces electrical load on the memory controller in multi-module configurations.

Registered ECC with major-brand chips

The registered design adds a buffer between the DRAM and the system bus, allowing larger memory populations without signal degradation. On-die ECC corrects single-bit errors and detects multi-bit errors to protect data integrity in critical workloads. Major-brand DRAM chips are used throughout and every module is tested before shipment.

Verify DDR4 RDIMM support and channel rules

Confirm that your server or workstation accepts DDR4 288-pin registered ECC DIMMs and does not require unbuffered or load-reduced modules. Check the system manual for approved memory speeds, maximum capacity per slot, and the correct slot population order for dual-channel operation. Desktop and laptop platforms cannot use these modules.

Questions about this item

Will the 1Rx8 registered DIMMs need any firmware updates or battery-backed settings to keep ECC working over time?

No firmware or battery-backed settings are required; the ECC function is handled by the memory controller once the modules are seated in the 288-pin slots.

What thermal limit appears first when the kit runs continuously at 2666 MHz inside a fully populated server chassis?

The modules have no heat spreader, so the DRAM junction temperature reaches its rated maximum before any other component throttles.

How much heat does the dual-rank kit add to the airflow path when the system operates all day at 1.20 V?

At 1.20 V each 4 GB stick draws only a few watts, so the total thermal load stays low even in a dense 288-pin DIMM array.
