Samsung 256GB DDR4 3200MHz PC4-25600 ECC LRDIMM Memory Module

The Samsung M386ABG40M51-CAE is a 256GB DDR4 LRDIMM that gives enterprise servers the headroom they need for memory-intensive workloads. By delivering 3200 MHz performance under the PC4-25600 rating, it feeds data to modern multicore processors quickly, helping large virtual environments, in-memory databases, and real-time analytics run smoothly without becoming memory bound.

This module follows the Load Reduced DIMM design, which places a register and data buffer between the memory controller and the DRAM chips. The layout eases signal noise, so administrators can populate more modules per channel without sacrificing stability. Error-correcting code is built in, adding an extra layer of protection against data corruption that can interrupt services or require costly rollbacks.

Engineered to the JEDEC DDR4 standard, the module operates at 1.2 V, keeping power draw and thermal output in check for dense server racks. Its eight-rank by four-bank organization and 288-pin interface match the requirements of many current dual-socket and multi-socket platforms that accept LRDIMM memory. Typical deployments include virtualization hosts that run dozens of guest machines, high-performance computing clusters, and enterprise resource planning servers where uninterrupted uptime and dependable throughput matter.
