## Long description

The Memory Module HPE DDR3 8GB 1333MHz (HPE 8GB 1x8GB Dual Rank x8 PC3L-10600E DDR3-1333) is a 240-pin DIMM designed for use in compatible systems requiring unbuffered, low-voltage DDR3 memory. This module operates at a memory clock speed of 1333 MHz with CAS latency 9 and runs at 1.35 V. It includes ECC (error-correcting code) functionality to help maintain data integrity and reduce the risk of memory errors in supported platforms. The module is intended to expand system memory capacity with a single 8 GB stick and is compatible with devices that accept standard 240-pin DDR3 DIMMs and support PC3L-10600E specifications.
Advantages
The HPE DDR3 8GB 1333MHz module provides stable performance through ECC support and a proven DDR3 architecture. Its low-voltage 1.35 V operation reduces power consumption compared with standard 1.5 V DDR3 modules while maintaining compatibility with systems that support PC3L modules. With CAS latency 9 and Dual Rank x8 organization, the module offers predictable access timings suitable for mixed workstation and server workloads. The 240-pin unbuffered DIMM format ensures straightforward installation in supported motherboards.
Suitable for
Upgrading memory capacity in compatible servers and workstations
Systems requiring ECC memory for improved data reliability
Environments where low-voltage (1.35 V) operation is preferred to reduce power draw
Replacement of failed or lower-capacity DDR3 240-pin DIMMs

How to use
Power down the system and disconnect power before installing the module. Open the chassis according to the system manufacturer's instructions and locate the appropriate 240-pin DIMM slot(s). Align the module notch with the slot key and press firmly and evenly into the socket until the retaining clips engage. After installation, reconnect power and boot the system. Verify that the BIOS/UEFI recognizes the new 8 GB module and that ECC (if supported by the platform) is enabled per the system settings.
Usage recommendations
Install modules in matched pairs or according to the motherboard vendor's memory population guidelines for optimal performance. Confirm system compatibility with PC3L-10600E DDR3-1333 unbuffered ECC memory and verify that the platform supports low-voltage 1.35 V operation and ECC features. When populating multiple slots, consult the server or workstation manual to follow recommended slot population and rank balancing for best stability.
