The TS512MSK72V3N-I by Transcend is a DDR3-1333 SODIMM module specifically engineered to provide an enhanced memory solution with a configuration of 512Mx72, which totals to 4GB of ECC (Error-Correcting Code) memory. It operates at a reduced voltage of 1.35V, contributing to better energy efficiency and reduced heat generation within the system. This module's ECC functionality is crucial for systems where data integrity is of utmost importance, as it can detect and correct internal data corruption, ensuring that critical applications run smoothly and reliably. The 204-pin interface is designed for compatibility with a broad range of laptops and small form factor systems that require DDR3 memory. With the inclusion of ECC memory, the TS512MSK72V3N-I is perfectly suited for professional workstations, servers, and systems where stability and reliability are critical.
