Cisco Compatible 8GB DDR4 RDIMM

This 8GB DDR4-2133 registered DIMM is built for Cisco UCS servers that require PC4-17000 memory. It uses major-brand DRAM chips and matches the OEM part number UCS-MR-1X081RU-G for drop-in upgrades.

DDR4 2133 registered limits

The module runs at 2133 MT/s with CL15 latency and 1.20 V on the standard DDR4 registered interface. Registered buffering adds one clock cycle of address/command delay, so the memory controller must support registered DIMMs and the target speed. ECC correction is mandatory for data integrity.

1Rx4 single-rank organisation

A single 1Rx4 rank presents one load per channel, allowing higher total capacity per channel than dual-rank alternatives. Servers that populate every slot with dual-rank modules may hit the controller rank limit before reaching the desired capacity. This module avoids that limit.

Questions about this item

Is the 8 GB 1Rx4 registered RDIMM the right choice for a Cisco server that needs a single 8 GB module?

Yes — this module is an 8 GB DDR4-2133 1Rx4 registered RDIMM built to match the Cisco UCS-MR-1X081RU-G part number, so it fits directly into a slot that expects that exact configuration.

What does the DDR4-2133 (PC4-17000) speed rating mean once the module is installed?

The memory will run at up to 2133 MT/s with a CL15 latency at 1.20 V, delivering the standard PC4-17000 bandwidth the server’s memory controller expects.

Does the 288-pin DDR4 RDIMM interface limit the module to registered ECC operation only?

Yes — the 288-pin registered DDR4 form factor with ECC and 1Rx4 organisation means it can only be used in slots that support registered ECC DDR4 memory.
