## Summary description

The HPE 840759-091 memory module offers 64 GB of DDR4 ECC memory with a clock speed of 2666 MHz. Designed for servers, this 288-pin DIMM module ensures reliable performance and data integrity, making it ideal for demanding applications. Its single 64 GB layout provides ample memory capacity for efficient multitasking and enhanced server performance.

## Long description

The HPE 840759-091 Memory Module provides 64 GB of DDR4 ECC server memory operating at 2666 MHz in a 288-pin DIMM form factor. Designed for enterprise server environments, this module supplies error-correcting capability to help maintain data integrity under sustained workloads. The single 64 GB configuration increases available memory capacity for virtualization, database processing, and memory-intensive applications while matching standard DDR4 timing and voltage requirements for compatible HPE and industry-standard servers.
Advantages
This 64 GB DDR4 ECC module reduces the risk of data corruption by using ECC technology and supports sustained memory throughput at 2666 MHz for consistent performance. Its 288-pin DIMM layout ensures compatibility with standard server DIMM slots, and the high-capacity single-module format simplifies memory upgrades and capacity scaling without requiring multiple smaller modules. The module is engineered for continuous operation in rack and blade systems common to enterprise deployments.
Suitable for
 Enterprise servers running virtualization platforms
 Database servers and in-memory databases
 High-performance computing and scientific workloads
 Application servers handling large datasets or many concurrent processes
 Server upgrades to increase memory capacity and reduce DIMM population
Key specifications
 Capacity: 64 GB
 Memory type: DDR4 ECC
 Clock speed: 2666 MHz
 Form factor: 288-pin DIMM
 Designed for server operation with error-correcting capability
How to use
Install the module into an available compatible 288-pin DIMM slot on a powered-off server following the server manufacturer’s instructions for memory population and slot order. Ensure the server supports DDR4 ECC memory at 2666 MHz and that firmware and BIOS settings are updated as required for full compatibility. After installation, power on the server and verify memory is detected and functioning via the system management interface or BIOS memory status screens.
Usage recommendations
For optimal reliability, install memory modules in matched pairs or follow the server vendor’s memory population guidelines. Use ECC-capable motherboards and enable any recommended BIOS settings for ECC operation. When upgrading, consider the server’s supported memory speed and capacity limits to maintain balanced performance and avoid mixing incompatible modules.
