Qnap 8GB DDR4-2400 DIMM

This Qnap system-specific memory module provides 8GB of DDR4 capacity at 2400 MHz. It is built for compatible Qnap NAS or server platforms that require 288-pin unbuffered DIMMs. The non-ECC design suits workloads that do not demand error correction.

DDR4-2400 bandwidth and latency limits

The module runs at PC4-19200 with a CAS latency of CL17 and operates at 1.20 V. Maximum throughput is capped by the DDR4-2400 standard, so applications needing higher memory bandwidth will not benefit from faster data rates on this part.

Upgrading from smaller or slower DDR4 modules

Replacing lower-capacity DDR4 DIMMs or slower DDR4 speeds with this 8GB kit adds headroom for virtualisation and multi-user file services. The jump is worthwhile when the platform supports 2400 MHz operation and the workload exceeds the current memory pool.

Questions about this item

Should I pick the 8 GB DDR4-2400 module or a different capacity for my QNAP NAS?

This part is an 8 GB DDR4-2400 DIMM. Choose it when your NAS has a free 288-pin slot and the manufacturer lists 8 GB as a supported size.

What does the DDR4-2400 (PC4-19200) rating mean once the stick is installed?

The module runs at 2400 MHz with a peak transfer rate of 19200 MB/s and CL17 latency, giving the NAS the exact speed and timing the vendor qualified.

Is this a standard 288-pin DDR4 DIMM and what does that limit in practice?

Yes, it uses the 288-pin DDR4 DIMM form factor at 1.20 V, so it fits only desktop-class DDR4 slots that accept unbuffered, non-ECC memory.
