About this item

Samsung M393AAG40M32-CAEBY is a 128GB DDR4 3200MHz ECC Registered DIMM (RDIMM) server memory module built for enterprise and data center environments. Featuring a 2S2Rx4 3D stacked die configuration and PC4-3200AA performance class, it delivers high memory density, strong stability, and reliable error correction for mission-critical workloads.

Pulled from working systems, tested and functional.

Key Features

  • Model: Samsung M393AAG40M32-CAEBY — 128GB DDR4 3200MHz (PC4-3200AA) ECC RDIMM
  • High Density Support: The 3D stacked die (3DS) architecture with 2S2Rx4 configuration enables systems to support maximum memory capacity in a single 288-pin RDIMM slot, ideal for high-density enterprise deployments.
  • Data Integrity: Integrated Registered ECC (Error-Correcting Code) functionality helps detect and correct memory errors in real time, ensuring improved system reliability and uptime for mission-critical workloads in data center environments.
  • Enterprise-Grade Design: Engineered specifically for server and workstation platforms requiring dependable high-capacity memory. Not compatible with consumer desktops or laptops due to RDIMM architecture and ECC requirements.
  • Compatibility: Supports enterprise platforms using standard 288-pin DDR4 RDIMM memory slots, including Dell PowerEdge, HPE ProLiant, Cisco UCS, and Supermicro server systems that specifically support 128GB quad-rank 3DS RDIMM modules. Support for lower-capacity RDIMMs does not guarantee support for this module — verify against your platform's memory QVL.
  • Note: You cannot mix RDIMMs with LRDIMMs or UDIMMs in the same system — ensure all installed modules are of the same type.

We test every memory before you do.

Every RAM module Server Part Deals sells passes an internal 4-stage testing protocol before it ships. While many resellers stop at a basic visual inspection, we validate identification data, memory capacity, performance, and stability under sustained load. Each module is checked to confirm that it meets or exceeds its rated specifications.

Stage 1: Physical Inspection

  • Connector and contact inspection
  • PCB damage and corrosion check
  • Component and solder integrity
  • Label and part-number verification

Stage 2: Module Validation

  • Capacity and speed validation
  • ECC and memory-type confirmation
  • Rank and configuration check

Stage 3: Performance Testing

  • Multi-round read/write cycles
  • Bandwidth and latency validation
  • Performance benchmarking
  • Load and stress simulation

Stage 4: Memory Integrity Testing

  • Full-address memory scan
  • Bit-error detection
  • ECC error monitoring
  • Final inventory verification
