8GB DDR4 2400 Module for QNAP NAS

This OWC module provides 8GB of DDR4 2400 memory in a 288-pin UDIMM form factor. It operates at 1.2V with CL17 latency and a 1Rx8 rank configuration. The non-ECC unbuffered design matches the specifications for QNAP TS-873U, TS-873U-RP and TS-877 systems. JEDEC compliance ensures a warranty-safe upgrade path.

Suits QNAP NAS upgrades needing non-ECC UDIMMs

This module fits owners of the listed QNAP models who want to add 8GB of DDR4 2400 memory using a standard UDIMM slot. It is not for systems that require ECC registered DIMMs or SODIMM form factors. Buyers needing error-correcting code memory should look elsewhere. The single-rank layout works with the validated QNAP platforms.

CL17 latency at DDR4 2400 speed

The CAS latency of CL17 at 2400 MT/s defines the module's timing profile for the compatible QNAP NAS units. Backward compatibility with 2133 MHz operation is supported. This timing specification determines whether the module matches the system's memory controller requirements. No heat spreader is included on the PCB.

Questions sur cet article

How much heat and power does the 1.2 V DDR4 2400 module draw when the NAS runs continuously?

The module operates at the standard DDR4 voltage of 1.2 V with no heat spreader, so thermal output stays low during all-day workloads.

What must the QNAP TS-873U already have for this 288-pin UDIMM to install and function?

An available 288-pin DDR4 UDIMM slot and a BIOS that accepts non-ECC unbuffered memory at CL17 timing.

Will this CL17 stick run stably alongside existing 2133 MHz modules in a TS-877?

Yes, the spec lists backward compatibility with 2133 MHz, so the faster module will down-clock to match the slower ones.
