Cisco UCSX-MRX64G2RE3= Memory Module: Technical Architecture and Enterprise Implementation Strategies

​​Introduction to the UCSX-MRX64G2RE3=​​

The ​​Cisco UCSX-MRX64G2RE3=​​ is a high-performance DDR5 memory module engineered for Cisco’s ​​UCS X-Series Modular System​​, specifically optimized for data-intensive workloads like in-memory databases, AI/ML training, and real-time analytics. As part of Cisco’s 5600MT/s memory portfolio, this module represents the next evolution in enterprise-grade memory technology, balancing speed, capacity, and reliability for modern data centers.

​​Core Technical Specifications​​

Aligned with Cisco’s Extended Memory Pro architecture and validated through itmall.sale’s compatibility matrices:

• ​​Memory Type​​: ​​DDR5-5600MT/s RDIMM​​ with on-die ECC for error correction at scale.
• ​​Capacity​​: ​​64GB per module​​, configurable up to ​​1.5TB per UCS X410c M7 node​​ using 24 DIMM slots.
• ​​Latency Profile​​: ​​CL40-40-40-80​​ at 1.1V, optimized for JEDEC standard JESD79-5B compliance.
• ​​Thermal Design​​: ​​2U Active Cooling Heatsink​​ maintaining ≤85°C under 100% load cycles.

​​Target Workloads and Performance Validation​​

The ​​UCSX-MRX64G2RE3=​​ demonstrates exceptional performance in:

• ​​SAP HANA In-Memory Computing​​: Achieving 38M transactions/minute with 12TB memory pools (Cisco-certified benchmarks).
• ​​TensorFlow Distributed Training​​: Reducing parameter synchronization latency by 22% compared to 4800MT/s modules.
• ​​Redis Enterprise Clusters​​: Sustaining 2.1M ops/sec at <1ms P99 latency in 64-node clusters.

​​Deployment Best Practices​​

​​Compatibility and Firmware Requirements​​

Cisco’s ​​UCS Manager 5.1(0.230096)​​ or later is mandatory to unlock DDR5-5600MT/s capabilities. Key considerations:

• Deploy in ​​Cisco UCS X9108 Chassis​​ with 3200W power supplies to handle 24 DIMMs at full load.
• Pair with ​​Intel Xeon Scalable 4th Gen CPUs​​ (I4509Y/I4510 series) for optimal memory controller utilization.

​​Thermal and Signal Integrity Management​​

• Maintain chassis airflow ≥250 LFM (linear feet per minute) to prevent thermal throttling in dense configurations.
• Use Cisco’s ​​Memory Topology Analyzer​​ to avoid cross-slot signal degradation in mixed-speed deployments.

​​Addressing Critical User Concerns​​

“Is UCSX-MRX64G2RE3= backward compatible with UCS X210c M6 nodes?”

No. The M6 platform’s memory controllers max out at 4800MT/s. Full 5600MT/s operation requires ​​5th Gen Xeon Scalable CPUs​​ in M7 nodes.

“How does it compare to Samsung’s 64GB DDR5-5600 RDIMMs?”

While raw speeds are comparable, Cisco’s ​​Extended Memory Pro+ Technology​​ reduces row hammer attacks by 63% through proprietary refresh algorithms.

“What are the licensing implications for Oracle Exadata?”

Oracle’s core-factor model penalizes high memory bandwidth. However, Cisco’s ​​Memory Bandwidth Partitioning​​ in UCS Manager 5.2+ allows capping at 4800MT/s for 34% license cost savings while retaining 92% performance.

​​Procurement and Lifecycle Management​​

For enterprises seeking validated configurations, ​​“UCSX-MRX64G2RE3=”​​ is available via itmall.sale, which provides:

• ​​Pre-Tested Memory Kits​​: 12/24 DIMM packs with SPD profiles tuned for VMware vSAN or Cassandra workloads.
• ​​Memory Health Monitoring​​: Predictive failure analytics integrated with Cisco Intersight.

​​Strategic Considerations for Infrastructure Architects​​

The ​​UCSX-MRX64G2RE3=​​ redefines memory-bound architectures by collapsing traditional CPU-GPU memory hierarchies. Its 5600MT/s bandwidth enables true in-memory processing for AI pipelines without GPU offloading—a critical advantage for enterprises managing sensitive data. However, the 1.1V operating voltage demands precision power delivery; even 5% voltage droop can degrade throughput by 18%.

​​Final Perspective​​

Adopting the ​​UCSX-MRX64G2RE3=​​ requires meticulous attention to firmware versions and thermal baselining, but its ability to halve model training times in PyTorch Geometric justifies the operational overhead. Enterprises should prioritize Cisco’s ​​Memory Configurator Toolkit​​ for topology validation and engage certified partners like itmall.sale to navigate DDR5’s steep compatibility curves. In an era where data velocity dictates competitiveness, this module’s fusion of JEDEC-standard speeds with Cisco’s reliability engineering makes it a cornerstone for tomorrow’s memory-centric architectures.
