## Summary description

HP Enterprise 512GB 2666 MT/s DC Persistent memory module provides high-capacity, low-latency non-volatile storage for servers and data-centre workloads. With 512GB capacity and 2666 MT/s speed, it supports persistent data retention across power cycles, accelerating in-memory databases, virtualization, and analytics while improving fault tolerance and restart times.

## Long description

HP Enterprise 512GB 2666 MT/s DC Persistent memory module provides 512GB of byte-addressable non-volatile memory designed for server and data-centre environments. This DDR4 persistent memory module operates at 2666 MT/s and is compatible with platforms that support Intel DC persistent memory technologies. It combines large-capacity memory with data persistence across power cycles to reduce application restart times and improve resilience for workloads that benefit from in-memory state retention.
Advantages
The HP Enterprise DDR4 Persistent Memory module offers high-capacity, low-latency persistent storage that sits between DRAM and storage. With 512GB capacity and 2666 MT/s performance, it enables applications to preserve data without full reloads after power loss or reboots. The module improves fault tolerance and shortens recovery windows for memory-resident databases, virtualization hosts, and analytics engines while maintaining DRAM-like access patterns.
Suitable for
In-memory databases and caching systems requiring large persistent working sets
Virtualization hosts (VM state persistence and fast restart)
Analytics and real-time processing workloads that benefit from low-latency persistent memory
Server platforms and data-centre systems supporting Intel DC persistent memory

How to use
Install the DDR4 Persistent Memory module into a server platform that explicitly supports HP Enterprise DC persistent memory modules and the required BIOS/firmware. Follow the server vendor’s memory population guidelines and order of installation to ensure correct channel interleaving and platform recognition. Configure the module in the supported persistent memory mode via system firmware or operating system tools according to your workload requirements (e.g., App Direct, Memory Mode). Verify that the operating system and applications are configured to make use of persistent memory features and test persistence behavior across controlled reboots.
Usage recommendations
Use the HP Enterprise 512GB 2666 MT/s Persistent Memory module in systems with validated support for Intel DC persistent memory technologies and updated firmware. For best results, pair these modules with server configurations that include appropriate DRAM and follow vendor guidelines for capacity balancing, firmware levels, and OS support. Validate application compatibility and backup procedures before relying on persistent memory for critical retention.
