64GB DDR4 ECC LRDIMM for servers

This 64GB DDR4 2666 module targets administrators upgrading compatible server or workstation platforms. It delivers ECC protection and load-reduced signalling in a single 288-pin DIMM. The part replaces Kingston KSM26LQ4/64H series modules. Buyers who need non-ECC UDIMMs or smaller capacities should look elsewhere.

Capacity and headroom

One module provides 64GB of registered memory at CL19 latency and 1.20V. The 4Rx4 organisation lets the memory controller address four ranks per channel, expanding total system capacity beyond standard dual-rank limits. Workloads that exceed this per-slot density will require additional DIMM slots or higher-capacity modules not described here.

Build integration

The DDR4 2666 PC4-21300 interface fits 288-pin DDR4 DIMM slots wired for ECC LRDIMM operation. No special cooling or voltage adjustment is needed beyond the standard 1.2V supply. Systems that do not support load-reduced ECC DIMMs cannot use this module.

Points forts

  • 64GB capacity handles heavy server workloads
  • DDR4 2666MHz speed moves data quickly
  • ECC LRDIMM design corrects errors automatically
  • CL19 latency at 1.2V reduces power draw
  • 288-pin 4Rx4 module fits compatible Kingston systems

Questions sur cet article

Will this 64 GB DDR4 2666 CL19 LRDIMM work alongside my existing DDR4 2666 RDIMMs?

LRDIMMs and RDIMMs cannot be mixed in the same system; the motherboard requires one memory type exclusively, so you would need to replace all modules with matching LRDIMMs.

How can I verify the module is running at DDR4 2666 CL19 1.20 V after installation?

Enter the BIOS or UEFI and confirm the memory frequency reads 2666 MT/s, CAS latency shows 19-19-19, and voltage is set to 1.20 V.

What comes in the box and do I need any extra parts to install this 288-pin DIMM?

The package contains the single 64 GB DDR4 2666 ECC LRDIMM; no additional cables, brackets or tools are required for a standard 288-pin server DIMM slot.
