OWC 8GB DDR4 2666 CL19 ECC SODIMM for ASUSTOR AS7110T

SKU CH-JR5S-JEG41

8GB DDR4 ECC SODIMM running at 2666MHz with CL19 latency for ASUSTOR AS7110T NAS upgrades

  • Total capacity8 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latencyCL19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered

Capacity 8GB

  • 8 GB capacity expands NAS multitasking headroom
  • DDR4 2666 speed matches ASUSTOR AS7110T spec
  • ECC protection guards data integrity in storage workloads
  • 2 V low voltage reduces system power draw
  • 260-pin SODIMM form factor fits the NAS memory slot

Capacity and fit

This 8GB DDR4 SODIMM is built specifically for the ASUSTOR AS7110T NAS. It uses a 260-pin form factor and operates at 2666MHz with CL19 latency. The module is unbuffered and includes ECC for data integrity in storage workloads.

Thermals noise and power

The stick runs at the standard 1.2V DDR4 voltage and has no heat spreader, keeping the profile thin for tight NAS slots. JEDEC compliance ensures stable operation within the system's thermal envelope without extra cooling. Power draw remains low during typical file-serving and backup tasks.

Upgrade path and when it matters

It replaces the ASUSTOR AS-8GECD4 module and is backward compatible with 2400MHz and 2133MHz slots. The jump is worth it when the NAS runs multiple containers or handles concurrent users and the current memory limit causes swapping. Buyers needing more than a single 8GB module or non-ECC memory should look elsewhere.

Questions about this item

How do I install this 260-pin DDR4 SODIMM into the ASUSTOR AS7110T, and which step is often missed?

Power off the NAS, unplug it, open the chassis, align the notch on the 260-pin module with the slot key, press firmly until the side clips click shut, then power on and verify the new 8 GB appears in the system info.

What maintenance or replacement will this ECC SODIMM need over time?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.2 V, so replacement is only needed if a memory error appears or capacity must be increased.

What limit appears first when this CL19 2666 MHz module runs sustained workloads?

The CAS latency of CL19 at 2666 MHz sets the access timing ceiling, so sustained throughput is bounded by that latency figure.
