## Long description

The HPE 16GB DDR3-1333 memory module is a 240-pin DIMM designed for server and workstation environments where data integrity and stable performance are critical. It provides 16 GB capacity with a 1333 MHz clock speed and supports ECC (error-correcting code) to reduce the risk of memory errors and improve system reliability. The module’s CAS latency of 9 and standard DIMM form factor make it compatible with many DDR3 platforms used in enterprise systems.
Advantages
This HPE memory module combines error-correcting ECC support with a 16 GB capacity to provide reliable operation under continuous workloads. The 1333 MHz speed balances performance and compatibility across a wide range of DDR3-based servers and workstations. The 240-pin DIMM format and vendor specification (HPE, MPN 647901-S21) simplify procurement and ensure compatibility with supported HPE systems.
Suitable for
Enterprise servers requiring ECC memory
Workstations running memory-intensive applications
System upgrades to increase stability and capacity
Data center environments prioritizing reliability
