64GB DDR4 2666MHz ECC LRDIMM

This single 64GB module uses DDR4 2666MHz PC4-21300 ECC Load Reduced DIMM technology with CL19 latency and 1.20V operation. It targets server and workstation administrators who need high-density registered memory for HP systems referencing part 880842-B21. The 4Rx4 organisation and major brand chipset support demanding multi-threaded workloads.

288-pin DIMM slot requirement

Installation requires an available DDR4 288-pin DIMM slot on a motherboard qualified for ECC LRDIMM modules at 2666MHz. The load-reduced design lowers electrical load on the memory controller, freeing capacity headroom for additional modules in populated channels. Verify your platform documentation for maximum supported density per slot and total system limit before ordering.

Lifetime warranty and US-based support

A-Tech backs every module with a lifetime warranty and provides complimentary United States based technical support before, during and after purchase. All units undergo quality assurance testing to meet stringent reliability standards for continuous server operation. No additional software or accessories are bundled with this memory upgrade.

Questions about this item

How does the 4Rx4 organisation affect sustained throughput on this 64 GB LRDIMM?

The four-rank layout lets the memory controller interleave requests across ranks, keeping the data bus busy during long workloads.

What thermal or acoustic impact should I expect from a 1.2 V DDR4 2666 module running continuously?

At standard 1.2 V the module stays within normal DIMM thermal limits and adds no audible noise in a server chassis.

Which slot type must my motherboard provide for this 288-pin DDR4 LRDIMM?

A DDR4 288-pin registered DIMM slot that supports load-reduced modules is required.
