📦 Description
The Samsung M393A8G40CB4-CWE is a 64GB DDR4 ECC Registered DIMM specifically engineered for enterprise-class server platforms that demand both high capacity and maximum reliability. With a clock speed of 3200MHz (PC4-25600) and a 2Rx4 rank structure, this module is ideal for handling virtualization, large database processing, analytics, and mission-critical applications.
Its ECC (Error-Correcting Code) feature ensures that memory errors are automatically detected and corrected, helping maintain system integrity and uptime in 24/7 deployments. This is critical in environments where every millisecond and data transaction counts. The 1.2V low-power profile contributes to reduced power consumption and thermal output, which is essential in dense server environments and large data centers.
Designed in the 288-pin RDIMM form factor, the module is fully compatible with a wide range of Intel Xeon and AMD EPYC server motherboards, making it suitable for new server builds or memory upgrades in scalable deployments. Whether you’re running complex enterprise applications, virtual machines, or cloud-native workloads, the M393A8G40CB4-CWE delivers the performance headroom and reliability required by IT professionals and data center operators.
As a product of Samsung, one of the most trusted names in DRAM technology, this memory module guarantees long-term durability, exceptional build quality, and compatibility across various server environments.
