A-Tech 64GB DDR4 2666 MHz ECC LRDIMM 4Rx4 CL19 1.2V 288-Pin Server RAM

SKU CH-NGX1-9PJ22

64 GB DDR4 ECC load-reduced DIMM at 2666 MHz with CL19 latency and 1.2 V operation

  • Capacity64GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredLoad Reduced

Capacity 64GB

  • 64 GB capacity lets servers handle larger workloads
  • DDR4 2666 MHz speed accelerates data throughput
  • ECC Load Reduced design corrects errors and reduces bus load
  • Quad-rank 4Rx4 organisation maximises density per slot
  • 2 V standard voltage keeps power draw efficient

Server-grade 64GB LRDIMM

This 64GB DDR4 2666 MHz ECC LRDIMM is built for servers and workstations that require load-reduced memory. The quad-rank 4Rx4 organisation allows high density in a single 288-pin module. It is not compatible with desktop or laptop computers.

1.2V operation with major-brand chips

The module runs at the standard DDR4 voltage of 1.2V and uses major-brand chipsets for dependable operation. The 288-pin DIMM form factor fits DDR4 server slots, while the load-reduced design reduces electrical load on the memory bus.

CL19 latency at 2666 MHz

Rated at PC4-21300 with CAS latency 19, the memory delivers consistent throughput for demanding workloads. ECC and load-reduced buffering help maintain signal integrity under sustained use. Standard 1.2V operation keeps power draw within DDR4 norms.

Questions about this item

What does the PC4-21300 rating mean for this DDR4-2666 module?

PC4-21300 is the JEDEC designation for DDR4-2666, confirming the module's rated speed of 2666 MHz and its standard 1.20V operating voltage.

Will this 288-pin LRDIMM fit in a standard server DIMM slot?

Yes, the 288-pin DIMM form factor matches the DDR4 server slot, but the system must specifically support Load Reduced ECC memory and 4Rx4 quad-rank modules.

What BIOS setting or seating step is often missed when installing quad-rank LRDIMMs?

Populate slots per the motherboard's channel guidelines for 4Rx4 modules, then verify the BIOS reports the full 64 GB capacity and ECC status at 2666 MHz.
