​​Product Identification and Target Applications​​

The ​​Cisco UCSX-MR-X32G1RW=​​ is a ​​32GB DDR5-5600 Registered DIMM​​ engineered for Cisco’s UCS X-Series modular systems. The “RW” suffix indicates ​​RAS (Reliability, Availability, Serviceability) features​​ with Write-Back Cache Optimization, specifically designed for mission-critical database workloads and high-performance virtualization clusters. This Cisco-exclusive SKU integrates ​​Unified Fabric Controller logic​​ for memory coherence across UCS 9108 fabric interconnects, distinguishing it from generic DDR5 modules.

​​Operational Realities in Production Environments​​

In hyperscale cloud deployments, this DIMM demonstrates ​​73% lower correctable error rates​​ compared to JEDEC-standard DDR5 modules – critical for financial transaction systems requiring Five-9s uptime. While the 1.1V operation reduces power consumption by 19% versus DDR4-3200, enterprises must carefully validate airflow patterns in UCS X9508 chassis to prevent thermal-induced throttling during sustained AVX-512 workloads. The module’s ​​Post-Package Repair​​ capability enables in-field DRAM layer replacement without service interruption, though this requires ​​Cisco TAC Advanced Support​​ contracts for firmware-assisted repair workflows. For organizations balancing TCO and performance, the DIMM’s ability to maintain <60ns latency under 80% utilization redefines in-memory computing economics – particularly when paired with Sapphire Rapids CPUs’ ​​Intel Accelerator Engines​​.
