Intel Optane DC Persistent Memory 128GB DDR4 2666 Apache Pass

Intel Optane DC Persistent Memory 128GB DDR4 2666MHz ECC Registered DIMM NMA1XXD128GPS

The Intel Optane DC Persistent Memory 100 Series (NMA1XXD128GPS) is a 128GB enterprise-class memory module designed to bridge the gap between traditional DRAM and high-capacity storage. Built on Intel’s Optane technology (Apache Pass), this module delivers a unique combination of large memory capacity, persistence, and high throughput, making it ideal for data-intensive applications and modern server environments.

Unlike standard memory, Optane Persistent Memory can operate in multiple modes, enabling systems to scale memory capacity dramatically while maintaining low latency access and data persistence.

NOTE: It is not standard RAM; it is a smart 'turbocharger' for your storage that learns which apps you use most so they load almost instantly."
