## Long description

HP Registered DDR5-4800 64GB (1x64GB) Dual Rank x4 CAS 40 HP Smart Memory Kit is a registered DDR5 RDIMM module designed for server and workstation environments that require increased capacity and dependable performance. The module operates at DDR5-4800 (4800 MT/s) with CAS latency 40-39-39 and supports EC8 error correction. Built in a 288-pin DIMM form factor, this 64GB dual-rank x4 memory module is intended for reliable system memory expansion and higher uptime in virtualization, database and cloud workloads.
Advantages
This HP Smart Memory kit provides increased memory capacity per slot while maintaining compatibility with registered DIMM server platforms. The DDR5-4800 speed delivers higher throughput compared with prior-generation memory, and the dual-rank x4 organization helps improve effective memory parallelism for server workloads. Error correction support (EC8) and registered buffering enhance system reliability and stability under sustained load. The module’s power-efficient DDR5 design contributes to lower energy usage per gigabyte.
Suitable for
Enterprise servers requiring expanded main memory for virtualization and consolidation
Workstations running large datasets or memory-intensive applications
Database servers and in-memory caching systems
Cloud and infrastructure platforms where uptime and error correction are important
