## Long description

The Memory Module HPE DDR3 8GB 1600MHz (HPE 8GB 1x8GB Single Rank x4 PC3-12800R CAS-11, MPN 647899-B21-RFB, EAN 5712505481790) is a registered DDR3 server memory module intended for use in compatible PCs and servers. It provides 8 GB of ECC-correcting DDR3 memory with a 240-pin DIMM form factor, 1600 MHz (PC3-12800) clock speed and CAS latency 11. The module operates at 1.5 V and follows standards for registered memory to support stability and error detection in systems designed for ECC and registered DIMMs.
Advantages
This HPE memory module delivers error-correcting code (ECC) support and registered (buffered) operation, which together contribute to improved data integrity and system stability in multi-module server configurations. The 1600 MHz clock speed with CAS-11 timing offers a balance between latency and throughput for workloads that require reliable memory performance. The 240-pin DIMM form factor and standard DDR3 voltage (1.5 V) ensure compatibility with systems that accept PC3-12800R modules.
Suitable for (tasks / use cases)
Server memory upgrades for systems that support DDR3 registered ECC DIMMs
Workloads requiring data integrity such as virtualization hosts and database servers
Replacing or matching existing PC3-12800R modules in enterprise systems

How to use
Power down the system and disconnect all power sources before installing the module. Consult the server or motherboard manual to identify supported DIMM slots and any population guidelines for registered ECC modules. Align the 240-pin DIMM with the slot keyed notch, press evenly until the retention clips engage, and ensure the module is seated fully. After installation, reconnect power and boot the system; check system firmware or BIOS/UEFI to verify the module is recognized and reporting ECC status. Follow any platform-specific procedures for memory population or configuration if required by the server vendor.
Usage recommendations
Use this module in systems that explicitly support DDR3 registered ECC (PC3-12800R) memory. For best results, install modules in matched pairs or according to the motherboard/server population rules, and verify firmware compatibility with HPE memory part numbers. Avoid mixing registered and unbuffered DIMMs in the same memory channel, and handle modules using ESD precautions.
