Key Features

• Model: M393AAG40M32-CAEBY — 128GB DDR4 3200MHz (PC4‑25600) ECC RDIMM
• Data Integrity: The ECC feature detects and corrects common single-bit data errors on the fly, preventing data corruption and enhancing system stability in demanding server environments.
• Enhanced Stability: As a Registered DIMM (RDIMM), it includes a buffer for command and address signals, which reduces electrical load on the memory controller. This allows motherboards to support more modules and higher overall capacities.
• High Performance: With a data rate of 3200 MT/s, it delivers high bandwidth crucial for data-intensive applications such as large-scale virtualization, in-memory databases (like SAP HANA), scientific computing, and enterprise resource planning systems.
• Power Efficiency: It operates at a low voltage of 1.2V, which contributes to reduced power consumption and lower cooling costs in data centers compared to DDR3 memory.
• Compatibility: compatible with a wide range of enterprise server platforms, including: Dell PowerEdge, Cisco UCS, HPE ProLiant, and Supermicro.
• RDIMMs cannot be mixed in the same system with LRDIMMs or UDIMMs.
