Dell-compatible 64 GB DDR4-2666 LRDIMM with ECC, 4Rx4 organisation and 1.2 V operation for server upgrades
This 64 GB DDR4 module is built for Dell servers that require PC4-21300 speed and load-reduced ECC registered operation. It targets IT teams maintaining existing infrastructure who need validated compatibility without OEM pricing.
The 4Rx4 rank layout with load-reduced buffering is the single specification that determines whether this module works in a given Dell slot; systems expecting standard registered DIMMs or a different rank configuration will not accept it.
Operating at 1.20 V, the module runs at standard DDR4 voltage for its density, keeping power draw and heat output in line with other 64 GB LRDIMMs of this speed. No additional cooling beyond normal server airflow is required.

The 64 GB module provides a large memory footprint per slot, allowing more virtual machines to run simultaneously without swapping to disk.
The DDR4-2666 interface caps peak bandwidth at 21300 MB/s per module, so sustained throughput cannot exceed that ceiling.
Yes, the 288-pin DDR4 LRDIMM is designed for standard registered DDR4 server slots that accept load-reduced modules.
