Capacity and form factor

This Brute Networks module delivers 128GB of DDR4 memory in a 288-pin LRDIMM package. It is built for Cisco servers that require high-density registered ECC memory to support large-scale virtualization or database workloads.

Compatibility checks

Verify that your Cisco platform accepts 8Rx4 LRDIMMs at 1.20V and supports the PC4-21300 speed grade. Confirm the maximum rank count per channel and total memory capacity allowed by the specific server model and BIOS revision before ordering.

Upgrade path

This module replaces lower-capacity RDIMMs or LRDIMMs when the application demands more memory per slot than standard dual-rank modules can provide. The jump is worthwhile when the workload is memory-bound and the server has free DIMM slots that can accommodate the 8Rx4 configuration.

Questions about this item

Does the module ship alone or with any extras like heatsinks or cables?

Only the single 128 GB DDR4 LRDIMM is supplied; no heatsinks, cables or additional hardware are included.

How do I decide between this 128 GB 8Rx4 LRDIMM and a lower-capacity RDIMM for my Cisco server?

Choose the 128 GB LRDIMM when you need maximum density per slot and your platform supports Load-Reduced modules; pick a smaller RDIMM if the system only accepts Registered DIMMs or you need fewer gigabytes per channel.

What does the 2666 MT/s rating mean for real workloads once installed?

The module runs at 2666 MT/s with 1.2 V ECC Registered operation, delivering PC4-21300 bandwidth for virtualization, databases and compute tasks that benefit from high memory throughput.
