QNAP 4GB DDR4 SDRAM Memory Module

Upgrade your NAS or computing system with the dependable performance of the QNAP 4GB DDR4 SDRAM Memory Module. Engineered for efficiency and reliability, this 4 GB DIMM uses DDR4 technology to deliver faster data access, smoother multitasking, and improved overall responsiveness for everyday workloads, media streaming, and NAS-driven tasks. With ECC capabilities and an unbuffered design, it’s built to provide stable operation in environments that demand accuracy and longevity while staying energy efficient with a low 1.20 V operating voltage. Whether you’re expanding a QNAP NAS, upgrading a workstation, or optimizing a compact server, this memory module helps you access the information your applications need in real time, reducing bottlenecks and keeping your data flowing.

• High-speed DDR4-2666 performance: This 4GB module runs at up to 2666 MHz (PC4-21333), delivering rapid data transfer rates that boost system responsiveness during multitasking, virtualization, and NAS-heavy workloads.
• ECC for reliability: Error-correcting circuitry helps detect and correct common data corruption events, enhancing data integrity for critical applications and long-running services.
• Unbuffered 288-pin DIMM design: A standard, unbuffered DDR4 module with 288 pins ensures broad compatibility with compatible motherboards, NAS enclosures, and servers that support ECC DDR4 DIMMs.
• Low-voltage efficiency: Operates at a slim 1.20V, helping to reduce overall power consumption and heat generation—beneficial for always-on NAS devices and dense server configurations.
• Compact 4GB capacity for balanced upgrades: An ideal amount of memory to complement existing RAM in small-to-midrange setups, enabling faster cached access and smoother operation without significant overclocking or power draw.

How to install QNAP 4GB DDR4 SDRAM Memory Module

• Power off the system, unplug all cables, and ground yourself to prevent static discharge before handling components.
• Open the device’s memory access panel or motherboard/slot cover as required by your NAS, server, or workstation documentation.
• Identify an available DDR4 DIMM slot that matches the 288-pin configuration and supports ECC unbuffered memory. If upgrading, remove the existing module only if you’re replacing it.
• Align the notch on the memory module with the key in the slot and insert at a gentle angle (about 45 degrees). Press down evenly until the module seats firmly and the locking clips snap into place.
• Repeat only if installing a second module, ensuring proper seating and clearance to avoid bending pins.
• Reassemble the device, reconnect power, and boot. Enter BIOS or system information to verify that the new 4GB module is detected and showing the correct speed (DDR4-2666) and ECC status.

Frequently asked questions

• Q: What is the memory capacity of this module?
  A: The module is 4 GB.
• Q: Does it support ECC?
  A: Yes. It includes ECC to help improve reliability in NAS and server environments.
