Samsung M393ABG40M5B-CYFC0 256GB DDR4-2933MHz RDIMM 8Rx4 CL21 Memory

Product Description

The Samsung M393ABG40M5B-CYFC0 is a high-capacity 256GB DDR4 Registered DIMM (RDIMM) memory module, engineered for demanding server and workstation environments. Operating at a speed of 2933MHz, this module provides substantial bandwidth, crucial for applications that require rapid data processing and high throughput. The RDIMM design incorporates a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-module configurations, which is standard in server systems. This specific module features an 8-rank (8Rx4) configuration. Rank is a measure of memory organization; an 8-rank module offers higher density and potentially improved performance by allowing the memory controller to interleave accesses across more banks of memory. This high-density configuration is particularly beneficial for servers that need to maximize their installed memory capacity within a limited number of DIMM slots, supporting memory-intensive tasks such as large database operations, virtualization, and complex scientific simulations. With a CAS Latency (CL) of 21, the M393ABG40M5B-CYFC0 strikes a balance between speed and latency, providing efficient performance for its class. The standard 1.2V operating voltage ensures compatibility with most modern DDR4 server platforms. This 256GB RDIMM is a premium component designed to enhance the performance, capacity, and reliability of high-end computing systems. The '-CYFC0' suffix typically indicates a specific revision or manufacturing batch, but the core technical specifications remain consistent with the M393ABG40M5B-CYF model.
