  • Minimal power consumption improves memory heat dissipation
  • Smooth operation for heavy applications at 2666 MHz
  • 100% Cisco compatibility protects your IT investment

128 GB DDR4-2666 TSV-RDIMM

This 128 GB DDR4-2666 TSV-RDIMM is built for Cisco servers that need registered ECC memory. It targets administrators upgrading UCS platforms where the UCS-MR-128G8RS-H part number is specified. The module delivers high-density capacity in a single slot.

Capacity and headroom

A 128 GB module can produce approx. 10K MIPS, giving the system more room to run complex applications. DDR4-2666/PC4-21300 operates at an effective bus speed with minimal power consumption and improved memory heat dissipation. The 2666 MHz memory speed runs heavy and numerous applications smoothly until the single-slot limit is reached.

Upgrade context

It replaces lower-capacity RDIMMs when the platform requires the UCS-MR-128G8RS-H form factor and registered signalling. The jump is worth it when workloads exceed the headroom of smaller modules and the qualified part list calls for this specific density and speed. Systems needing unbuffered DIMMs or a different pin-out cannot use this module.

Highlights

  • Run complex apps with 128 GB RDIMM capacity
  • Optimal performance from DDR4-2666 effective bus speed
  • Minimal power consumption improves memory heat dissipation
  • Smooth operation for heavy applications at 2666 MHz
  • 100% Cisco compatibility protects your IT investment

Questions about this item

Will the 128 GB DDR4-2666 RDIMM work alongside existing DDR4 modules in a Cisco UCS server?

The module is 100% guaranteed compatible with Cisco systems and will not void SMARTnet or system warranty. Mixing capacities is supported by the platform memory controller; populate slots per the server memory population guide for best performance.

How can I verify the 2666 MHz speed and 128 GB capacity are active after installation?

Check the server BIOS or Cisco UCS Manager inventory; it will show each DIMM running at DDR4-2666 (PC4-21300) with 128 GB per module. The operating system memory report should also reflect the total added capacity.

Does the package include only the RDIMM or are heat spreaders and cables supplied?

The box contains the 128 GB DDR4-2666 TSV-RDIMM only. No additional heat spreaders, cables or brackets are included; the module installs directly into the server DIMM slots.
