Capacity and fit

This Qnap RAM-16GDR4A1-UD-2400 module adds 16 GB of DDR4 memory to compatible desktop NAS units. It runs at 2400 MHz with a CAS latency of CL17 and operates at 1.20 V. The 288-pin unbuffered DIMM is designed for systems that accept standard UDIMM modules.

What the module changes

Installing this stick increases the total memory available for file caching, virtual machines and concurrent applications. The non-ECC, unbuffered design means it suits platforms that do not require error-correcting or registered memory. No additional software or accessories are included in the package.

Suitable buyers and limits

This module suits owners of Qnap desktop NAS devices that support DDR4-2400 UDIMM memory and have a free slot. Buyers who need ECC protection, registered DIMMs or speeds other than 2400 MHz should look at alternatives that match those requirements.

Questions about this item

Does the 288-pin DDR4 module require any periodic maintenance or replacement?

The 16 GB DDR4-2400 UDIMM has no moving parts and no service schedule; it only needs replacement if a memory test reports errors.

What limits sustained performance first — the CL17 latency or the 2400 MHz speed ceiling?

The 2400 MHz data rate caps throughput before the CL17 timing becomes the bottleneck.

How much heat and power does the 1.20 V unbuffered DIMM produce when running 24/7?

At 1.20 V the module draws minimal power and generates little heat, so standard chassis airflow is sufficient.
