## Summary description

The HPE 664691-001-RFB memory module offers 8 GB of DDR3 RAM with a clock speed of 1600 MHz. Designed for PCs and servers, it features a 240-pin DIMM form factor and CAS latency of 11, ensuring reliable performance for demanding applications.

## Long description

The HPE 8 GB DDR3 1600 MHz memory module (HPE part number 664691-001-RFB, EAN 5711045975905) is a 240-pin DIMM designed for use in compatible PCs and servers. It provides 8 GB of DDR3 volatile memory with a rated clock speed of 1600 MHz and a CAS latency of 11, enabling stable operation in environments that require moderate to high memory bandwidth. The module adheres to standard 240-pin DIMM dimensions and signaling for DDR3 installations and is intended for systems that accept unbuffered DIMMs or the specific HPE-supported configuration noted by the manufacturer.
Advantages
The module offers a reliable 8 GB capacity suitable for multitasking and server applications, with DDR3 architecture that balances performance and power consumption for legacy platforms. A 1600 MHz memory clock combined with CAS latency 11 provides predictable timing characteristics for operating systems and applications that depend on consistent memory latency. The 240-pin DIMM form factor ensures physical compatibility with standard DDR3 DIMM slots on motherboards and HPE server systems that support this part number.

Key specifications
Brand: HP Enterprise
Manufacturer part number (MPN): 664691-001-RFB
EAN: 5711045975905
Capacity: 8 GB
Memory type: DDR3
Clock speed: 1600 MHz
CAS latency: 11
Form factor: 240-pin DIMM
How to use
Power down the system and disconnect power before opening the case. Locate an empty compatible 240-pin DDR3 DIMM slot on the motherboard or remove an existing module if replacing. Align the notch on the module with the slot key and press evenly on both ends until the retention clips engage. Reconnect power and boot the system; verify that the BIOS/UEFI and operating system recognize the new 8 GB module. Follow any server vendor instructions for memory population order and pairing requirements if installing multiple modules.
Использование рекомендации
The module should be installed in systems that explicitly support DDR3 1600 MHz 240-pin DIMMs and the HPE part number to ensure compatibility. When mixing modules of different speeds or latencies, the system will typically operate at the lowest common performance settings. For optimal reliability, use matched modules in the same channel and consult the system or motherboard documentation for supported configurations.
