QNAP 4GB DDR4 2400 MHz UDIMM Memory Module

The QNAP RAM-4GDR4A1-UD-2400 is a 4GB DDR4 memory module that delivers a straightforward upgrade path for compatible QNAP NAS systems. By adding this module, you give the NAS additional room to cache active data and run multiple applications without slowing down.

Operating at 2400 MT/s and requiring only 1.2 V, the module moves data quickly while keeping power draw and heat output in check. It uses a UDIMM format with a standard 288 pin layout and installs in minutes—just open the chassis, align the notch with the slot, press down until the clips lock, and reboot.

The module is qualified for models such as TVS-972XU-RP, TS-677, TS-1677X, TS-977XU, TS-2477XU-RP, TS-877XU, TVS-872XU-RP, and TS-877XU-RP. Whether you run virtual machines for development, stream high bit rate video to multiple clients, or manage a busy file server in a small office, the extra memory helps the system respond faster and handle more simultaneous connections.

Because the module does not include a heat spreader or decorative LEDs, it fits neatly into enclosures with limited airflow and keeps the focus on reliable day-to-day operation rather than visual effects.

Highlights:

• 4GB DDR4 memory rated at 2400 MT/s
• 288 pin UDIMM that uses an unbuffered design and fits standard NAS memory slots
• 1.2 V operating requirement lowers power consumption and heat
• Qualified for TVS-972XU-RP, TS-677, TS-1677X, TS-977XU, TS-2477XU-RP, TS-877XU, TVS-872XU-RP, and TS-877XU-RP
• No heat spreader or LED lighting, ideal for clean and quiet builds
