A-Tech 64GB (2x32GB) DDR4 2666 ECC LRDIMM 2Rx4 Server RAM

SKU CH-XVFH-K6922

A 64 GB dual-channel kit of two 32 GB DDR4 2666 ECC load-reduced DIMMs with 2Rx4 organisation and CL19 latency for servers and workstations

  • Rated speedDDR4 2666 (PC4 21300)
  • ChipsetMajor Brand Chipset
  • CAS latencyCL19
  • Rated voltage1.2 V

Capacity 64GB (2 x 32GB)

  • 64GB dual-channel kit expands server memory capacity for heavier workloads
  • Load-reduced ECC DIMMs protect data integrity and reduce electrical load on the memory bus
  • DDR4 2666 MHz CL19 timing delivers fast, responsive performance for demanding applications
  • 2Rx4 dual-rank organisation increases memory density within each 32GB module
  • Standard 1.2V operation keeps power draw low while maintaining stability

64GB DDR4 2666 ECC LRDIMM Kit

This 64GB kit contains two 32GB DDR4 2666 MHz ECC Load Reduced DIMMs. Each module uses a 2Rx4 organisation and runs at 1.20V with CL19 latency. The 288-pin form factor is built for server and workstation platforms that require registered memory.

For servers needing ECC Load Reduced DIMMs

Suitable for administrators upgrading compatible DDR4 servers or workstations that specifically support LRDIMM technology. Not for desktop or laptop systems, which cannot use Load Reduced modules. Buyers who need unbuffered ECC or standard registered DIMMs should look at a different memory type.

DDR4 2666 ECC LRDIMM 2Rx4 at 1.20V

The decisive specification is the Load Reduced ECC design combined with a 2Rx4 rank structure at DDR4 2666 speed. Only systems qualified for DDR4 ECC LRDIMM modules can accept this kit; all other platforms will reject it.

Questions about this item

What slot type and pin count does the 288-pin DDR4 LRDIMM kit require on the motherboard?

The kit uses standard DDR4 DIMM slots with 288 pins; the motherboard must support DDR4 ECC Load Reduced memory in the same form factor.

Which orientation and seating step is most often missed when installing the 2Rx4 dual-rank modules?

Align the module notch with the slot key, press straight down until both side latches click fully into the retention notches on each 32 GB stick.

What ongoing care does the 1.2 V ECC LRDIMM kit need to maintain reliability?

Keep server airflow clean so the modules stay within thermal limits; ECC corrects single-bit errors automatically, and no scheduled replacement is required unless a module fails.
