Cisco Server DDR5 RDIMM

This 16 GB DDR5 4800 MHz ECC registered module is built for Cisco server platforms. It operates at 1.1 V with CL40 latency and a single-rank 1Rx8 layout. The 288-pin RDIMM form factor fits compatible Cisco motherboards that require registered memory with error correction.

Registered ECC memory for Cisco platforms

The module plugs directly into DDR5 RDIMM slots on supported Cisco systems. Registered buffering reduces electrical load on the memory controller, allowing larger total capacities. ECC functionality detects and corrects single-bit errors to protect data integrity in mission-critical workloads. No heat spreader is included, so airflow in the chassis must be sufficient.

IT teams maintaining Cisco infrastructure

This part suits administrators upgrading or repairing Cisco servers that specify the UCSX-MRX16G1RE1 compatible part number. It is not for desktop PCs, laptops, or consumer motherboards that use unbuffered non-ECC memory. Builders needing higher densities or different speeds should verify the exact part number required by their specific Cisco model.

Questions about this item

What sustained-load limit appears first on this DDR5 4800 CL40 module?

The CAS latency of CL40 at 4800 MT/s sets the timing boundary that governs sustained throughput.

How much heat and power does the module draw during continuous operation?

Running at 1.1 V without a heat spreader keeps power draw low and thermals manageable in a server chassis.

Which server platform must already be present for this RDIMM to function?

It is validated for Cisco systems that accept the UCSX-MRX16G1RE1 part number.
