256GB Intel Optane persistent memory module delivers impressive responsiveness and stable DDR-T performance.
Improved database workloads significantly with consistent 2666 MHz reliability.
Enterprise-grade persistent memory offering dependable scalability.
Stable integration with supported Intel platforms and predictable throughput.
High-capacity Optane module ideal for memory-intensive applications.
The Intel Optane DC Persistent Memory Module NMA1XXD256GPSU4 is a 256 GB DDR-T DIMM 288-pin module delivering 2666 MT/s (PC4-21300) performance with data persistence capabilities.
This module offers 256 GB of persistent memory operating at 2666 MT/s (PC4-21300), enabling high-bandwidth, low-latency access for data-intensive workloads.
The NMA1XXD256GPSU4 uses a standard 288-pin RDIMM form factor, compatible with Intel Xeon Scalable platforms that support DDR4-2666 memory.
It requires Intel Xeon Scalable processors (2nd Gen or newer) and Intel C620-series or later chipsets with BIOS support for Optane DC Persistent Memory.
Unlike DRAM, Optane DC Persistent Memory retains data without power, offering higher capacity at lower cost per GB while delivering DRAM-like latency and bandwidth.
Optane DC Persistent Memory provides significantly lower latency (<350 ns) and higher endurance than NAND SSDs, bridging the gap between DRAM and storage tiers.
You gain up to 3× higher memory capacity per socket, reduced I/O latency, and faster data access for in-memory databases, analytics, and virtualization workloads.
It supports Memory Mode for transparent capacity expansion and App Direct Mode for byte-addressable persistence, enabling software to control data placement.
Power down the system, install the module into a compatible DDR4 slot, update BIOS settings to enable Optane DC Persistent Memory, then reboot and configure per Intel guidelines.
Yes. In App Direct Mode, data written to Optane DC Persistent Memory is retained across power cycles, protecting critical information without battery backup.
Supported OSes include Windows Server 2019/2022, various Linux distributions (RHEL, CentOS, Ubuntu) with Intel Memory and Storage Tool and DAX filesystem support.
Ideal for in-memory databases, real-time analytics, virtualization, high-performance computing, and large-scale caching where large memory footprints and persistence matter.
It features up to 38 PB lifetime write endurance, ECC protection, and advanced wear-leveling for enterprise-grade reliability under heavy workloads.
Use Memory Mode for transparent acceleration, App Direct Mode for custom data structures, tune BIOS interleave settings, and leverage Intel PMDK libraries.
Intel provides the Intel Memory and Storage Tool (IMST) for configuration, health monitoring, firmware updates, and advanced diagnostics of Optane DC Persistent Memory.
Intel offers a 5-year limited warranty, global technical support, firmware updates, and extensive documentation to ensure reliable deployment and maintenance.
