OWC 16GB DDR4 2666 CL19 ECC SODIMM QNAP TS-h973AX memory upgrade

SKU CH-ZXQF-S2180

16 GB DDR4 2666 ECC SODIMM adds error-correcting memory to the QNAP TS-h973AX at 1.2 V

  • Capacity16GB
  • Type260-Pin DDR4 ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes
  • 16 GB capacity expands NAS multitasking headroom
  • DDR4 2666 CL19 speed matches QNAP TS-h973AX spec
  • ECC protection guards data integrity in storage workloads
  • 2 V low voltage keeps power draw minimal
  • 260-pin SODIMM form factor fits the NAS slot directly

Targeted NAS Upgrade

This OWC module adds 16GB of DDR4 ECC memory to the QNAP TS-h973AX. It uses the 260-pin SODIMM form factor required by that system. The unbuffered design matches the platform's memory controller. Buyers who need non-ECC memory or a different pin count cannot use this part.

DDR4 2666 Interface Limits

The module runs at 2666 MT/s with a CL19 latency at 1.2V. It is backward compatible with 2400 and 2133 MT/s bus speeds. Systems that only accept registered DIMMs or require a voltage other than 1.2V will not support this module.

Single Deciding Specification

ECC error correction is the feature that determines suitability for the TS-h973AX. The platform requires ECC unbuffered SODIMMs to maintain data integrity. A non-ECC module would leave the system without that protection.

Questions sur cet article

Should I buy one 16GB stick or two for the TS-h973AX?

The TS-h973AX has four SODIMM slots; adding a single 16GB module upgrades one slot and leaves three free for future expansion.

What does the 2666MHz rating actually deliver in the NAS?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency, providing the maximum JEDEC-standard speed the TS-h973AX memory controller supports.

Is the 260-pin DDR4 ECC SODIMM interface compatible with my QNAP?

Yes, the 260-pin DDR4 ECC unbuffered SODIMM matches the TS-h973AX slot and chipset requirements; it also downclocks to 2400MHz or 2133MHz if the system requires it.
