Advantages
This memory module offers a significant boost to system responsiveness and overall throughput, allowing servers to manage demanding workloads with greater efficiency. By utilizing advanced DDR4 technology, it provides a balance of high-speed performance and energy efficiency, operating at a low voltage of 1.2V. The rigorous testing and authentication process applied to this HPE component ensures seamless compatibility with supported server platforms, minimizing the risk of hardware conflicts and system downtime. Its robust design is built to meet the high standards required for continuous operation in professional environments.
Suitable for
Enterprise-grade servers and workstations
Data-intensive computing and virtualization
Professional IT infrastructure upgrades
Small and medium business server environments
When it may not be suitable
This memory module is designed specifically for server and workstation hardware and is not compatible with standard consumer desktop motherboards that require non-ECC memory or different form factors. It may also not be suitable for older systems that do not support DDR4 technology or the 2666 MHz clock speed.
Key specifications
Capacity: 16 GB
Memory Type: DDR4
Clock Speed: 2666 MHz
Form Factor: 288-pin DIMM
Voltage: 1.2 V
Error Correction: ECC
CAS Latency: 19
How to use
To install the memory module, ensure the server is powered off and disconnected from the power source. Open the server chassis and locate the available DIMM slots on the motherboard. Align the notch on the memory module with the key in the DIMM slot to ensure correct orientation. Press the module firmly into the slot until the side clips snap into place, securing the module. Once installed, close the chassis, reconnect the power, and verify that the system BIOS or operating system recognizes the new memory capacity.
What to consider before purchase
Verify compatibility with your specific server model and motherboard
Check if your system supports DDR4 ECC memory
Ensure there is an available 288-pin DIMM slot
Confirm if your current memory configuration allows for mixing modules
Usage recommendations
For optimal performance and system stability, it is recommended to install memory modules in matching pairs or sets as specified by your server manufacturer's guidelines. Always handle the module by its edges to avoid electrostatic discharge damage to the components.
