## Long description

The Memory Module HPE DDR3 8GB 1333MHz (HP Enterprise, MPN 647897-B21-RFB, EAN 5711045943720) is a single 8 GB DDR3 DIMM designed for use in PCs and servers. This module operates at 1333 MHz (PC3L-10600), uses a 240-pin DIMM form factor and low-voltage 1.35 V operation. It is a Dual Rank x4 module with CAS latency 9 and includes ECC support to help detect and correct memory errors, improving data integrity for business and server workloads.
Advantages
This HPE DDR3 8GB 1333MHz module provides a balance of capacity and compatibility for legacy DDR3 platforms. Its low-voltage 1.35 V design reduces power consumption compared to standard 1.5 V modules while maintaining the same performance profile. The ECC capability and Dual Rank configuration enhance error detection and memory access reliability, which is important for systems running critical applications and multi-user environments. The 240-pin DIMM form factor ensures straightforward installation in compatible desktop and server motherboards.
Suitable for
 Upgrading server memory in HP Enterprise and compatible server platforms that support DDR3 ECC DIMMs
 Replacing or expanding memory in compatible workstation and desktop systems that accept 240-pin DDR3 DIMMs
 Systems requiring ECC protection for improved data integrity in business applications and virtualization

How to use
Power down the system and disconnect mains power before installing the memory module. Open the chassis following the manufacturer's service manual, locate an available 240-pin DDR3 DIMM slot, and align the module notch with the slot key. Firmly press the module into the slot until the retention clips engage. After installation, reconnect power and start the system. Verify that the BIOS/UEFI recognizes the new 8 GB module and that ECC is enabled if required by the platform. If mixing with existing modules, ensure compatible speed, voltage, and ECC support to avoid instability.
Usage recommendations
Use this module in systems that explicitly support DDR3 ECC DIMMs and low-voltage 1.35 V operation. For multi-module configurations, install matched modules (capacity, speed, voltage, and rank) to maintain optimal stability and performance. Consult the server or motherboard compatibility list and firmware documentation before upgrading to ensure support for Dual Rank modules and ECC features.
