Built to exacting specifications with the finest chips and components available, Transcend DDR4 SO-DIMM memory modules undergo rigorous laboratory testing to ensure unrivaled performance and stability for mainstream notebooks. Because small form-factor cases and slim notebook enclosures usually come hand-in-hand with tightly spaced components with limited room for heat dissipation, Transcend's DDR4 SO-DIMM operated at a nominal voltage of just 1.2V not only reduces heat production, but also reduces overall power consumption to save more energy. An economical memory upgrade option for most popular desktop and notebook models out there, Transcend's DDR4 DRAM modules are engineered with the finest chips available, at the same time stringently tested to make sure they deliver optimal speeds, endurance, reliability, and compatibility across platforms. For desktops and laptops Transcend offers a comprehensive range of DDR4 standard long-DIMMs and compact SO-DIMMs to enhance memory bandwidth for desktops and laptops alike. All modules are tested across various motherboard platforms and operating systems with achieving maximum compatibility in mind. Unlock next-gen performance DDR4 delivers far less response time and application loading time than its predecessors DDR3, DDR2, and DDR. It is higher in RAM density but lower in power consumption, having brought energy requirement further down to 1.2V, making it best suited for memory-intensive applications. Quality chips fully tested for reliability Selected from only the finest, brand-name DRAM chips available, Transcend’s memory modules undergo countless in-house stress tests and evaluations to ensure they deliver absolute quality and reliability
