System-Specific DDR4 Upgrade

This OWC memory module is built for QNAP NAS models TS-1677X, TS-432PXU, TS-432PXU-RP, TS-432XU and TS-432XU-RP. It provides a single 16GB DDR4 2400 CL17 2Rx8 288-pin 1.2V Non-ECC UDIMM to expand system memory capacity.

JEDEC DDR4 2400 CL17 Specification

The module runs at DDR4 2400 (PC4-19200) with CAS latency 17 and 1.2V operation. It is unbuffered, non-ECC, dual-rank 2Rx8 and fully JEDEC compliant. Backward compatibility with 2133MHz systems is supported.

Low-Voltage Unbuffered Operation

At 1.2V the module draws minimal power and generates little heat without a spreader. Unbuffered design keeps electrical loading light for stable operation in the listed QNAP NAS units during continuous workloads.

Points forts

  • 16 GB capacity expands NAS memory for heavier workloads

Questions sur cet article

Will the 2400MHz speed run at full rate in my TS-432XU?

The module is rated at DDR4 2400 PC4-19200 CL17 and will operate at that speed if the NAS memory controller supports it; otherwise it will downshift to 2133MHz automatically.

Is the 288-pin DDR4 UDIMM the correct form factor for the TS-1677X?

Yes, this is a 288-pin unbuffered non-ECC DDR4 UDIMM, which matches the slot type used in the listed QNAP models.

Does the 16GB stick need a heat spreader to fit inside the TS-432PXU?

No heat spreader is fitted, so the low-profile module clears standard NAS DIMM sockets without clearance issues.
