Crucial 64GB DDR4 2666 MHz ECC LR-DIMM Server Memory

Overview

The Crucial CT64G4LFQ4266 is a 64GB DDR4 Load-Reduced DIMM (LR-DIMM) designed specifically for servers that require high memory capacity and reliable performance. Operating at 2666 MHz, it provides consistent bandwidth to support demanding workloads such as virtualization, real-time analytics, and large-scale data processing. Its error-correction code (ECC) functionality helps maintain data integrity by detecting and correcting single-bit errors, reducing the risk of system crashes and corrupted data.

This memory module’s load-reduced design decreases the electrical load on the memory controller, allowing more DIMMs to be installed per channel without sacrificing stability. Running at a low voltage of 1.2 V, it also contributes to lower power consumption and reduced heat generation, which is critical in data center environments. Validated for Intel Xeon platforms and compatible with many OEM server systems, it offers a straightforward upgrade path for increasing memory density in rack or blade servers.
