## Long description

The Hewlett Packard Enterprise 4GB 1RX4 PC3L12800R11 memory module (MPN 713981-S21-RFB, EAN 5704174985822) is a 4 GB DDR3 registered DIMM designed for use in HPE server systems. It supports PC3L-12800 (DDR3-1600) data rates and operates as a low-voltage (PC3L) module to reduce power consumption in rack and blade servers. The module’s single-rank x4 organization (1RX4) and registered ECC design provide compatibility and stability for enterprise workloads where consistent memory operation is required.
Advantages
This HPE 4GB module provides a balance of capacity and energy-efficient operation through PC3L technology, helping to lower system power draw compared with standard-voltage DDR3 modules. Its registered (buffered) design with ECC support improves stability in multi-module server configurations, reducing the risk of memory-related errors in enterprise applications. The standardized form factor and manufacturer references (HP Enterprise, MPN 713981-S21-RFB) ensure straightforward compatibility checks for HPE systems.
Suitable for
 HPE rack and blade servers requiring DDR3 registered ECC memory
 Enterprise applications with moderate memory capacity needs (4 GB per module)
 Systems where reduced power consumption is desired due to PC3L low-voltage operation
 Server maintenance and memory upgrades to restore or expand installed RAM

How to use
Power off the server and follow the manufacturer’s service manual for safe access to the memory bays. Handle the module by its edges and avoid touching components or contacts. Align the notch on the DIMM with the socket and press firmly until the retention clips engage. After installation, power on the server and verify that the system BIOS/UEFI recognizes the new memory capacity and that any required memory configuration or mirroring settings are correct. For multi-module installations, install modules in recommended slot pairs or banks as specified by the server documentation.
Usage recommendations
Use this module in compatible HPE servers and ensure firmware/BIOS versions are up to date for best compatibility. When upgrading, match module type (registered ECC, PC3L, and similar speed) across channels to maintain stability and performance. Store spare modules in anti-static packaging and within recommended temperature and humidity ranges before installation.
