OWC 8GB DDR4 2400 Module

This 8GB DDR4 2400 CL17 UDIMM is designed for specific QNAP NAS models including the TS-1232PXU, TS-1232PXU-RP, TS-1232XU, TS-1232XU-RP and TS-1273U. It operates at 1.2V as a non-ECC unbuffered module. The single-rank 1Rx8 configuration fits standard 288-pin slots. It replaces QNAP part numbers RAM-8GDR4A0-UD-2400 and RAM-8GDR4A1-UD-2400.

Capacity and Headroom

The 8GB capacity adds memory headroom for multitasking and larger file handling within compatible QNAP systems. It runs at DDR4 2400 speeds with CL17 latency and supports backward compatibility with 2133MHz operation. Systems requiring ECC error correction or registered memory cannot use this module. Total capacity limits depend on the specific NAS model and available slots.

JEDEC Compliant DDR4 Upgrade

This module is 100% compliant with JEDEC standards and ROHS directives for a warranty-safe upgrade. It is validated to meet or exceed OEM specifications for the listed QNAP devices. The non-ECC unbuffered design matches the requirements of the target platforms. Buyers needing ECC functionality or higher densities must select a different module.

Questions about this item

Will this DDR4 2400 CL17 module run with older 2133 MHz sticks I keep in my QNAP TS-1232XU?

Yes, the specification notes backward compatibility with 2133 MHz DDR4, so the 2400 CL17 module will down-clock and operate alongside existing 2133 MHz sticks.

How can I verify the 8 GB 1Rx8 module is detected at 2400 MHz after installation in a TS-1273U?

Check the QNAP system information or resource monitor; it should show the new module as 8 GB DDR4 running at 2400 MHz with CL17 timings.

Does the single 288-pin UDIMM arrive alone, or are screws and a heat spreader included for the TS-1232PXU-RP?

The package contains only the bare 8 GB DDR4 UDIMM; no heat spreader, screws or additional accessories are supplied.
