OWC 8GB DDR4 2400 UDIMM for QNAP NAS

This 8GB DDR4 2400 CL17 UDIMM module is built for QNAP TS-677, TS-832PXU, TS-832PXU-RP, TS-832XU and TS-832XU-RP systems. It replaces QNAP part numbers RAM-8GDR4A0-UD-2400 and RAM-8GDR4A1-UD-2400. The module suits administrators expanding memory in these specific NAS units. Buyers needing ECC registered memory or capacities beyond 8GB per slot cannot use this part.

Installation is a standard UDIMM insertion

The 288-pin unbuffered DIMM fits the memory slots on the listed QNAP models without tools. Align the notch, press firmly until the retention clips click, then power on to verify the new capacity. The most common issue is seating the module incompletely, which leaves the system showing the original memory total. Reseating usually resolves this. No BIOS configuration is required on these appliances.

The decisive specification is 1Rx8 CL17 at 1.2V

This single-rank by eight organisation with CL17 latency matches the OEM timing the QNAP firmware expects. The JEDEC-standard 1.2V operation ensures compatibility with the platform's memory controller. Systems requiring dual-rank modules, lower latency bins or 1.35V operation will not work correctly with this module. Backward compatibility with 2133MHz buses is supported.

Points forts

  • Boosts NAS responsiveness with 8 GB DDR4 2400 CL17 module
  • JEDEC-standard 1.2 V unbuffered DIMM ensures warranty-safe upgrade
  • Single 1Rx8 288-pin stick installs in minutes without tools
  • Backward compatible with 2133 MHz systems for flexible deployment
  • Replaces QNAP part numbers RAM-8GDR4A0-UD-2400 and RAM-8GDR4A1-UD-2400

Questions sur cet article

How can I confirm the module is running at 2400MHz CL17 after installing it in my TS-832XU?

Open the QNAP system information page or BIOS; the memory section should report DDR4 2400 (PC4-19200) with a CAS latency of 17 for the new module.

What comes in the package and do I need any extra parts to fit it into a TS-677?

The box contains one 8GB 288-pin DDR4 UDIMM; no additional brackets, cables or tools are required for installation.

Should I pick the 8GB 1Rx8 CL17 stick or look for a different rank or latency for my TS-832PXU?

This 8GB 1Rx8 CL17 module matches the QNAP part numbers RAM-8GDR4A0-UD-2400 and RAM-8GDR4A1-UD-2400, so it is the correct specification for those models.
