## Long description

The Memory Module HP Enterprise DDR5 64GB 4800MHz is a 288-pin registered ECC DIMM operating at 4800 MT/s with CL40 latency and 1.1V nominal voltage. Designed for servers and workstations, this HP Enterprise DDR5 64GB module provides increased bandwidth and improved latency compared with DDR4 3200 MT/s modules while supporting data integrity and stable operation under heavy workloads.
Advantages
HPE DDR5 SmartMemory delivers higher bandwidth and lower latency at 4800 MT/s compared with DDR4 3200 MT/s, improving overall system throughput. Modules are tested and qualified on HPE server platforms to ensure signal integrity and compatibility. Built-in ECC and registered design reduce the risk of memory errors and unnecessary DIMM replacement, helping to minimize server downtime. The module uses high-quality components and operates at 1.1V for energy-efficient high-speed performance.
Suitable for
Enterprise servers running database, virtualization, or compute-intensive workloads
Workstations used for content creation, CAD, or engineering simulations
Systems requiring ECC memory and registered DIMMs for data integrity
Upgrading server memory to improve bandwidth and latency without increasing module count
