## Summary description

The HP 664690-001 memory module offers 8 GB of DDR3 ECC RAM with a clock speed of 1333 MHz. Designed for PC and server use, it features a 240-pin DIMM form factor and CAS latency of 9. This reliable memory module enhances system performance and stability, making it ideal for demanding applications and multitasking environments.

## Long description

The HP 664690-001 memory module provides 8 GB of DDR3 ECC RAM running at 1333 MHz in a 240-pin DIMM form factor. Engineered for HP Enterprise systems but compatible with many PCs and servers that accept DDR3 ECC 240-pin modules, this memory module uses a CAS latency of 9 and operates at a voltage of 1.35 V. The ECC (Error-Correcting Code) capability helps detect and correct single-bit errors, supporting system stability for business-critical and multitasking environments.
Advantages
This HP 8 GB DDR3 1333 MHz ECC module increases available memory capacity while maintaining data integrity through ECC technology. The 240-pin DIMM design ensures straightforward installation in compatible desktop and server motherboards. With a CAS latency of 9 and a 1333 MHz clock speed, it delivers consistent performance for applications that require reliable memory throughput. Low operating voltage (1.35 V) contributes to energy-efficient operation compared with older higher-voltage modules.
Suitable for
 Enterprise and small business servers requiring ECC memory
 Workstations used for data analysis, virtualization, and multitasking
 PC motherboards with DDR3 240-pin ECC DIMM slots
 Systems needing a stable upgrade to 8 GB of RAM

How to use
Power down the system and disconnect it from the power source before installing the memory module. Open the system chassis to access the DIMM slots and consult the motherboard or server manual to identify ECC-compatible 240-pin sockets and the recommended slot population order. Align the module notch with the slot key, press evenly until the retention clips engage, and ensure the module is fully seated. Reassemble the chassis, reconnect power, and start the system. Verify that the BIOS/UEFI recognizes the new 8 GB module and that ECC functionality is enabled if required by the platform.
Usage recommendations
For optimal compatibility and stability, install this HP 8 GB DDR3 1333 MHz ECC module in matched pairs when supported by the motherboard, and use modules with the same speed, voltage, and CAS latency. Check the server or motherboard documentation for maximum supported capacity per slot and supported memory configurations. If the system does not boot or does not recognize the module, reseat the memory and confirm BIOS/UEFI settings and platform ECC support.
