Two green DDR4 ECC SODIMM modules with black chips, no heat spreader

OWC

OWC 32GB (2x16GB) DDR4 2666 ECC SODIMM memory upgrade

SKU CH-K0J4-DHFD5

ECC DDR4 SODIMM kit adds 32 GB at 2666 MHz CL19 for the ASUSTOR AS7110T NAS

  • Capacity32GB (2 x 16GB)
  • Type260-Pin DDR4 ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes

Capacity 32GB (2 x 16GB)

  • 32 GB total capacity from two 16 GB modules for multitasking headroom
  • DDR4 2666 CL19 speed keeps data flowing to the CPU
  • ECC protection detects and corrects single-bit errors automatically
  • 2 V low-voltage operation reduces heat and power draw
  • Backward compatible with 2400 MHz and 2133 MHz systems

Capacity and Configuration

This kit delivers 32 GB of DDR4 ECC memory as two 16 GB SODIMM modules. It is built for the ASUSTOR AS7110T NAS and runs at 2666 MHz with CL19 latency. The 2Rx8 unbuffered design operates at 1.2 V and uses the standard 260-pin form factor.

Who this suits and who should look elsewhere

The modules suit administrators who need error-correcting memory for a compatible ASUSTOR lockerstor and want a straightforward capacity increase. Buyers whose systems require registered or load-reduced DIMMs, or who need speeds above 2666 MHz, cannot use this kit. It also does not fit desktop DIMM slots or non-ECC consumer laptops.

Workload headroom and limits

The 32 GB total provides comfortable headroom for virtualisation, container workloads and large file caches on the target NAS. Performance scales down automatically to 2400 MHz or 2133 MHz if the platform demands it. Workloads that exceed 32 GB or require higher frequencies will hit the capacity and speed ceiling of this kit.

Questions about this item

Does the ASUSTOR AS7110T need anything other than two free 260-pin SODIMM slots to run this 32 GB kit?

The NAS only requires two empty 260-pin DDR4 SODIMM slots; the kit includes both 16 GB modules so no extra parts are needed.

Will these 2666 MHz ECC modules down-clock if my AS7110T currently has 2400 MHz memory installed?

Yes, the modules are backwards compatible with 2400 MHz and 2133 MHz, so they will run at the lower speed when mixed.

How can I confirm the ECC feature is active after installing the kit in my AS7110T?

Check the NAS system information or memory diagnostic screen; it should report 32 GB total and show ECC enabled for the new modules.
