QNAP 4GB DDR4 SDRAM Memory Module

Upgrade your QNAP NAS with a reliable 4GB DDR4 memory module engineered for durability and sustained performance. This DDR4-2666 (PC4-21333) 260-pin SoDIMM delivers faster data access, smoother multitasking, and improved caching for media streaming, virtualization, and file-serving workloads. Built to withstand continuous operation, it helps unlock your NAS's potential, reduces bottlenecks, and extends the life of your existing system. Whether you’re adding memory for a small business, home media server, or data-intensive applications, this module is designed to enhance responsiveness and reliability without requiring a full system overhaul.

• Blazing DDR4-2666 speed for NAS workloads - The 2666 MHz data rate dramatically improves read and write operations, particularly when indexing large libraries, transcoding media on the fly, running multiple containers, or supporting virtual machines within supported QNAP NAS systems. By reducing memory access latency and increasing bandwidth, this module helps your NAS respond faster during peak hours, boosting overall user experience and reliability. The higher speed also helps preserve cache hotness and reduces bottlenecks during simultaneous tasks, so streaming, backups, and file sharing happen with less jitter.
• 4GB capacity for improved multitasking - With a 4GB memory upgrade, the NAS can hold more active data in RAM, which translates into smoother multitasking and faster app launches. This is especially valuable for small businesses or home users who run multiple apps like media servers, surveillance, cloud sync, and virtualization. More RAM means fewer slowdowns when the NAS handles large file transfers or runs background indexing while serving clients. This upgrade also helps with caching frequently accessed data for faster retrieval, enabling quicker response times for users and devices connected to the network.
• 260-pin SoDIMM form factor for broad NAS compatibility - The compact 260-pin DDR4 SO-DIMM design fits the common memory slots found in many QNAP NAS models and other space-constrained devices. This form factor enables easy, tool-free installation in supported units, reducing downtime and enabling fast upgrades. The module is engineered to seat securely in the slot with reliable retention clips, ensuring stable operation under vibration and continuous operation typical in NAS environments. It’s a compact solution that leaves room for additional expansion or other hardware in small-form-factor enclosures.
• PC4-21333 standard alignment for reliable bandwidth - This memory adheres to the PC4-21333 specification, ensuring predictable performance across compatible motherboards and NAS enclosures. Operating at DDR4-2666 speeds, it provides solid memory bandwidth for data-intensive tasks, buffering, and caching. The standardization also helps compatibility with a wide range of test profiles, reducing the risk of incompatibilities in multi-vendor environments and giving you confidence during upgrades.
• Quality you can rely on for NAS uptime - QNAP memory modules are manufactured to strict tolerances and tested to ensure compatibility with NAS hardware. Expect stable, long-term operation under continuous workloads, with reduced risk of memory-induced crashes or performance dips. The module is designed to withstand operating temperatures and voltage fluctuations common in 24/7 NAS deployments, offering a dependable upgrade path that helps to future-proof your storage solution while maintaining dependable uptime for critical services.
