## Long description

The HPE 664688-001 Memory Module is a 4 GB DDR3 ECC DIMM operating at 1333 MHz and designed for server and PC environments that require error-correcting memory. This 240-pin module from HP Enterprise uses ECC technology to detect and correct single-bit memory errors, helping maintain system stability during sustained workloads. With a CAS latency of 9 and a low operating voltage of 1.35 V, the module is suitable for systems that support DDR3L-compatible memory and aim to balance performance with energy efficiency.
Advantages
This HPE DDR3 4GB 1333MHz ECC module provides ECC error correction for improved data integrity and reduced risk of crashes caused by memory faults. The 240-pin DIMM form factor ensures compatibility with standard DDR3 memory slots in many servers and some desktops. Operating at 1333 MHz with CAS latency 9 delivers predictable timing characteristics for mixed-load environments. The 1.35 V operating voltage reduces power consumption compared with higher-voltage DDR3 modules while maintaining reliable operation in compatible systems.
Suitable for
 Server upgrades requiring ECC memory for improved reliability
 Workstations and PCs that support 240-pin DDR3 DIMMs and ECC functionality
 Systems used for virtualization, databases, and continuous operation workloads
 Replacing faulty or mismatched memory to restore stability

How to use
Before installation, power down the system and disconnect it from the mains. Open the chassis according to the manufacturer’s instructions and locate an empty, compatible 240-pin DDR3 DIMM slot or remove an existing module if replacing. Align the notch on the module with the slot and press firmly and evenly until the retaining clips engage. After installation, close the chassis, reconnect power, and boot the system. Verify that the BIOS/UEFI recognizes the module and that ECC is enabled if the platform supports it.
Usage recommendations
Use this HPE DDR3 4GB 1333MHz ECC module in systems that explicitly support ECC DDR3 memory and the 240-pin DIMM form factor. For best results, install memory modules in matched pairs or kits where the platform requires dual-channel operation, and consult the server or motherboard documentation for supported memory configurations and maximum capacities.
