HP 840759-091 Description

▼

Upgrade your server performance with the HP 840759-091 64GB 2666MHz 4Rx4 288 Pin ECC DDR4 Memory. Designed specifically for HPE ProLiant servers, this high-capacity memory module is ideal for data-intensive applications, virtualization, and enterprise-level workloads. Compatible with a wide range of ProLiant server models including ProLiant DX, DL, ML, SL, BL, XL, and CL series, it ensures seamless integration and reliable performance across your server infrastructure.

This memory module boasts impressive specifications that cater to demanding server environments. With a substantial 64GB capacity and a fast 2666MHz memory speed, it delivers efficient data processing and multitasking capabilities. The ECC (Error-Correcting Code) technology enhances data integrity by detecting and correcting memory errors, which is critical for maintaining system stability in mission-critical operations. Operating at a low voltage of 1.2V, it balances power efficiency with performance. The 4Rx4 rank and CL19 latency timing optimize memory access speeds, while the 288-pin LRDIMM form factor ensures compatibility with Gen 3 through Gen 10 HPE server generations.
