Intel 128GB 2666MHz DDR4 PC4-21300 DIMM Optane Persistent Memory Module – NMA1XXD128GPS

Intel Optane DC Persistent Memory 128GB DDR4 2666MHz — NMA1XXD128GPS

The Intel NMA1XXD128GPS is a 128GB Intel Optane DC Persistent Memory module in DIMM form factor operating at 2666MHz (PC4-21300). Unlike traditional DRAM, Optane Persistent Memory combines the speed of memory with the persistence of storage — data survives power cycles, enabling new application architectures for in-memory databases, AI/ML inference, and high-performance analytics. Designed for Intel Xeon Scalable (Cascade Lake and later) server platforms.

Key Features

• 128GB Persistent Memory: Large-capacity memory that survives power cycles
• Near-DRAM Speed: Much faster than NAND SSD — bridges the gap between DRAM and storage
• App Direct Mode: Applications access persistent memory directly for maximum performance
• Memory Mode: Extends DRAM capacity transparently using Optane as volatile memory
• Intel Xeon Scalable: Designed for Cascade Lake and later Xeon platforms
• Data Persistence: Data survives power loss — eliminates warm-up time for in-memory databases

Frequently Asked Questions

What is the difference between App Direct and Memory Mode?

In App Direct mode, applications access Optane directly as persistent storage-class memory. In Memory Mode, Optane acts as large volatile memory with DRAM as a cache — transparent to applications.

Does data persist after a power loss?

Yes — in App Direct mode, data written to Optane Persistent Memory survives power cycles, eliminating database warm-up time.

Is this compatible with all Xeon servers?

No — Optane DC Persistent Memory requires Intel Xeon Scalable Cascade Lake (2nd Gen) or later processors. Earlier Xeon generations are not supported.
