Technical Architecture & Memory Specifications

The Samsung M426R4GA3BB0-CQK0L is a high-performance 32GB DDR5-4800 ECC Unbuffered SO-DIMM engineered for maximum data integrity and system stability. It features a Dual Rank (2Rx8) organization and operates at a highly efficient 1.1V with an integrated on-module Power Management IC (PMIC). With a CAS Latency of CL40 (40-39-39), this Sideband ECC SODIMM ensures rapid data access while actively detecting and preventing single-bit memory errors.

Platform Compatibility & Server/Desktop Application

Designed specifically for mobile workstations, compact servers, NAS units, and embedded enterprise platforms requiring error-correcting code protection. This 262-pin EC4 form factor memory is strictly compatible with systems that support DDR5 ECC Unbuffered SO-DIMMs. It is ideal for next-generation micro-servers and high-end mobile workstations utilizing compatible Intel Core, Intel Xeon, or AMD Ryzen/EPYC processors that explicitly support ECC SODIMM memory architecture.
