QNAP-ready 16 GB DDR4 module

This 16 GB DDR4 UDIMM runs at 2400 MHz with CL17 latency and 1.2 V operation. It is built as a 2Rx8 unbuffered non-ECC stick on a 288-pin PCB. The module is validated for QNAP NAS systems using the RAM-16GDR4A0-UD-2400 part reference.

Tool-free press-in installation

Align the notch with the slot key and press down until the retention clips click. No heat spreader means low profile clearance in tight NAS bays. The only common issue is mixing this non-ECC stick with ECC modules, which the platform will reject at POST.

Steady throughput under continuous NAS workloads

Rigorous stress testing under load confirms stability during prolonged file transfers and RAID rebuilds. The 1.2 V rating keeps thermals modest without active cooling. Sustained write patterns show no throttling or error correction events over extended periods.

Questions about this item

How do I confirm the module is running at DDR4 2400 CL17 after installation?

Open the BIOS or a system utility such as CPU-Z and verify the reported speed shows 2400 MT/s with a CAS latency of 17 at 1.20 V.

What comes in the package and do I need any extra parts for a QNAP NAS?

The box contains one 16 GB 288-pin UDIMM module; no additional cables, brackets or heat spreaders are required for compatible QNAP NAS units.

Which capacity and speed version should I choose for a system that supports PC4-19200?

Select the 16 GB DDR4 2400 (PC4-19200) CL17 1.20 V UDIMM — it matches the rated speed, voltage and form factor for that platform.
