Cisco UCS-MR-128G8RS-H 128GB DDR4 Server Memory Module

Expand compatible server memory capacity with the Cisco UCS-MR-128G8RS-H 128GB DDR4 ECC Registered memory module. This 288-pin DIMM is specified at 2666MHz with a PC4-21300 rating, CL19 latency, 1.2V operation, and octa-rank x4 construction. The detailed specification makes it suitable for infrastructure teams planning high-density memory upgrades, replacing a failed module, or standardizing server populations around a validated Cisco memory configuration. As with all server memory, the host platform, supported memory type, rank arrangement, and population rules should be confirmed before installation.

Key Features

  • 128GB DDR4 server memory capacity
  • 2666MHz operating speed
  • ECC Registered memory technology
  • 288-pin DIMM form factor
  • 1.2V octa-rank x4 design

Server Memory Specifications

The 128GB capacity provides high-density memory expansion, while ECC Registered technology is intended for compatible server-class memory architectures. The PC4-21300 rating, CL19 timing, and octa-rank x4 layout should be evaluated together with the host system's validated memory population requirements.

Use Cases

  • Increasing memory capacity in a compatible Cisco server
  • Replacing a high-density DDR4 memory module
  • Supporting virtualization and data-intensive workloads
  • Maintaining matched server DIMMs for service operations

Compatibility

Verify the target Cisco UCS server, DDR4 support, ECC Registered requirement, rank compatibility, speed, voltage, and memory population rules before installation. Follow the platform's approved DIMM arrangement.
