QNAP 16GB DDR4 3200 MHz PC4-25600 UDIMM Memory Module

The QNAP RAM-16GDR4K1-UD-3200 is a 16 GB DDR4 memory module designed to give compatible QNAP NAS enclosures the extra headroom they need for demanding workloads. Working at 3200 MHz and built to the PC4-25600 standard, it moves data quickly so tasks such as large file transfers, virtualization, and real-time backups finish sooner and run more smoothly.

The module follows a 288-pin UDIMM layout and uses a non-ECC, unbuffered design, which keeps latency low while maintaining stability that suits everyday server environments. Because it was developed specifically for models like the QNAP TS-855X, you can install it with confidence that the NAS firmware will recognize the module and apply the correct settings automatically.

Adding this memory is a practical upgrade for small businesses that see more users joining shared folders, creative teams that stream high-resolution media directly from the NAS, or home lab enthusiasts who want to spin up extra containers and virtual machines without slowdown. More physical memory lets QNAP’s caching and snapshot features operate efficiently, reducing reliance on slower disk access and improving overall responsiveness.

Installation is straightforward: power down the NAS, open the chassis, insert the module into an available memory slot, and secure the cover again. After powering up, the system will detect the new capacity, allowing you to enable heavier workloads without replacing your existing storage or processor.
