This ultra-high-density 128GB Quad Rank module delivers the maximum DDR4 memory capacity per slot available — enabling massive total system memory configurations for the most memory-intensive enterprise workloads including large-scale virtualization, in-memory databases, AI\/ML, and high-performance computing. Error-Correcting Code (ECC) technology continuously detects and corrects single-bit memory errors in real time, ensuring data integrity in mission-critical environments. The registered (buffered) design reduces electrical load on the memory controller, enabling stable high-density multi-DIMM configurations across enterprise server platforms.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e128GB Ultra-High Density:\u003c\/strong\u003e Maximum DDR4 capacity per slot — achieve the highest possible total system memory with fewer DIMMs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3200MHz — Fastest DDR4 Speed:\u003c\/strong\u003e PC4-25600 delivers the highest bandwidth available on DDR4 server platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eECC Error Protection:\u003c\/strong\u003e Real-time single-bit error correction ensures data integrity for mission-critical server workloads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegistered (Buffered) Design:\u003c\/strong\u003e Enables stable, high-density multi-DIMM server configurations without signal degradation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSamsung DRAM:\u003c\/strong\u003e Industry-leading manufacturing quality with proven enterprise-grade reliability and longevity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e M393AAG40M32-CAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Samsung\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMemory Type:\u003c\/strong\u003e DDR4 SDRAM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Type:\u003c\/strong\u003e RDIMM (Registered \/ Buffered)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 128GB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed:\u003c\/strong\u003e 3200MHz (PC4-25600)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAS Latency:\u003c\/strong\u003e CL22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTiming:\u003c\/strong\u003e 22-22-22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 1.2V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor:\u003c\/strong\u003e 288-Pin DIMM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRank:\u003c\/strong\u003e Quad Rank (4Rx4)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie Organization:\u003c\/strong\u003e x4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eData Width:\u003c\/strong\u003e 72-bit (64-bit + 8-bit ECC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eError Correction:\u003c\/strong\u003e SECDED (Single-bit correction, Double-bit detection)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e 0°C to 85°C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eUse Cases\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMassive-Scale Virtualization:\u003c\/strong\u003e VMware vSphere, Microsoft Hyper-V, and KVM deployments requiring the highest possible memory capacity per DDR4 server node\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn-Memory Databases:\u003c\/strong\u003e SAP HANA, Oracle TimesTen, and VoltDB deployments requiring terabyte-scale memory pools across server clusters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAI\/ML Training Infrastructure:\u003c\/strong\u003e CPU-side memory for large-scale AI\/ML training pipelines and data preprocessing at maximum DDR4 capacity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHPC and Scientific Computing:\u003c\/strong\u003e MPI-based simulation and modeling workloads requiring maximum per-node memory capacity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCompatible with DDR4 RDIMM slots supporting Quad Rank modules — verify your platform's Quad Rank DIMM support before ordering\u003c\/li\u003e\n\u003cli\u003eCAE is the base qualification code for this Samsung 128GB DDR4 3200MHz Quad Rank x4 RDIMM series — verify against your server's memory QVL before ordering\u003c\/li\u003e\n\u003cli\u003eDo not mix with DDR4 UDIMMs, LRDIMMs, or Dual Rank modules where Quad Rank mixing is restricted\u003c\/li\u003e\n\u003cli\u003eFor multi-DIMM stability, populate channels with matched capacity, speed, and rank modules\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat is the advantage of a Quad Rank DIMM over a Dual Rank DIMM?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eQuad Rank DIMMs pack twice the DRAM ranks of Dual Rank modules, enabling higher capacity per slot (128GB vs 64GB).
