64GB DDR4 2666 ECC LRDIMM Server Module

This 64GB DDR4 2666 ECC LRDIMM module is built for servers and workstations that require high-density registered memory with error correction. The load-reduced design lowers electrical load on the memory bus, allowing larger capacities per channel. It operates at 1.2V with a CAS latency of CL19.

Major-brand Hynix chips ensure validated

The module uses major-brand Hynix components that match the HMAA8GL7AMR4N-VK and HMAA8GL7CPR4N-VK part numbers. Each unit undergoes quality-assurance testing before shipment, reducing the risk of DOA sticks and ensuring reliable operation in qualified platforms.

288-pin DIMM form factor fits standard DDR4 server

The 288-pin DDR4 DIMM form factor installs directly into compatible server and workstation motherboards. Load-reduced buffering and 4Rx4 organisation mean the platform must explicitly support LRDIMM topology; systems limited to standard RDIMM or UDIMM will not accept this module.

Questions sur cet article

How often will the 64GB DDR4 2666 ECC LRDIMM 4Rx4 module need replacement?

The module uses Major Brand Chips tested to stringent standards and is backed by a Lifetime Warranty, so it is designed to last the life of the server without scheduled replacement.

What limits sustained throughput on the 288-pin DDR4 2666 CL19 LRDIMM?

Sustained throughput is capped by the DDR4 2666 MT/s data rate and CL19 latency; the 4Rx4 Load Reduced organisation maximises capacity per channel within that bandwidth ceiling.

How much heat and power does the 1.20V 64GB LRDIMM produce under all-day load?

Operating at the standard DDR4 1.20V, the module draws minimal power per gigabyte; the Load Reduced buffer reduces electrical loading on the memory bus, keeping thermals low during continuous operation.
