32GB DDR4 module for QNAP TS-h NAS

This single 32GB DDR4 2666 CL19 UDIMM upgrades compatible QNAP TS-h series rackmount NAS units. It targets administrators expanding memory in TS-h1277XU-RP, TS-h1677XU-RP, TS-h2477XU-RP or TS-h977XU-RP systems. The non-ECC unbuffered design matches the OEM specification for these platforms.

Tool-free DIMM slot installation

Installation follows the standard UDIMM procedure: power down, open the chassis, align the 288-pin module with the slot and press until the latches engage. The 1.2V JEDEC voltage requires no BIOS adjustment. The main risk is mixing this non-ECC stick with existing ECC modules, which can prevent boot or disable error correction.

32GB capacity per module

Each module delivers 32GB of DDR4 2666 memory in a single rank 2Rx8 configuration. This density determines how many slots are needed to reach a target total capacity. Systems requiring ECC registered memory or a different form factor cannot use this module.

Points forts

  • 32GB capacity expands multitasking headroom for demanding NAS workloads
  • DDR4 2666 speed with CL19 latency delivers responsive data throughput
  • 2V low-voltage operation reduces power draw and heat in rackmount enclosures
  • JEDEC and RoHS compliant design ensures warranty-safe upgrades for TS-h series
  • Single 2Rx8 288-pin UDIMM module simplifies installation across four compatible models

Questions sur cet article

How do I confirm the 32GB DDR4 2666 module is running at CL19 after installing it in my TS-h1277XU-RP?

Enter the QNAP BIOS or use the QTS Resource Monitor to verify the memory reports 2666 MHz speed and CL19 latency for the installed DIMM.

Does the single 32GB 2Rx8 UDIMM ship with any installation tools or extra cables for the TS-h1677XU-RP?

The package contains only the 288-pin DDR4 module; no tools, cables or additional hardware are included.

Should I choose the 32GB 2666 CL19 stick or a lower-capacity kit for my TS-h2477XU-RP?

Select this 32GB 2Rx8 DIMM when you need maximum capacity per slot; choose smaller modules only if your configuration requires multiple ranks across channels.
