Key Features

• Model: Samsung M393A8G40AB2-CWEBY — 64GB DDR4 3200MHz (PC4-3200AA) ECC RDIMM
• Optimized Performance: Built with a 2Rx4 dual-rank configuration running at 3200 MT/s with CL22 latency, this module delivers strong memory bandwidth and efficient data handling, making it suitable for enterprise server configurations where performance and stability are critical.
• 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 a wide range of enterprise platforms using standard 288-pin DDR4 RDIMM memory slots, including Dell PowerEdge, HPE ProLiant, Cisco UCS, and Supermicro server systems that support DDR4-3200 RDIMM modules.
• Note: You cannot mix RDIMMs with LRDIMMs or UDIMMs in the same system — ensure all installed modules are of the same type.
