  • Low 1.20V voltage lowers power draw in dense server configurations

64GB Load-Reduced DDR4 Module

This 64GB DDR4-2666 LRDIMM adds high-capacity memory to compatible servers. It operates at 1.20V with ECC and registered buffering for data integrity. The module targets administrators expanding dense virtualisation hosts or large in-memory databases. Systems limited to lower densities or non-LRDIMM slots cannot use this part.

Capacity and headroom

A single stick delivers 64GB at PC4-21300 speed, letting a populated chassis reach very large totals without extra slots. Workloads that fit inside this allocation run without swapping. Datasets exceeding the installed amount will still page to storage. The DDR4-2666 rate sets the bandwidth ceiling for memory-bound tasks.

Thermals, noise and power draw

Low-profile height keeps airflow paths clear in tightly packed enclosures. At 1.20V the module draws modest power per gigabyte under load. Passive cooling relies on chassis fans; no onboard fan adds acoustic noise. Thermal output scales with utilisation but stays within normal DDR4 limits.

Perguntas sobre este artigo

Will this 64GB DDR4-2666 LRDIMM run alongside my existing 32GB RDIMMs at 1.20V?

Load-Reduced and Registered DIMMs cannot be mixed in the same channel; the system will not train with both types installed.

How can I verify the module is operating at the rated 2666 MT/s and ECC is active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode to confirm 2666 MT/s speed, 1.20V voltage and ECC enabled status.

Does the MEM-DR464L-SL01-LR26 package include a heatsink or any installation hardware?

The module ships as a bare low-profile LRDIMM; no heatsink, screwdriver or additional hardware is included.
