ASUSTOR NAS memory upgrade kit

This OWC kit supplies 16 GB of DDR3 memory as two 8 GB unbuffered UDIMMs rated at 1600 MT/s with CL11 latency and 1.5 V operation. It is built to JEDEC and RoHS standards and validated for the ASUSTOR AS7009RD and AS7012RD network-attached storage models. The modules are non-ECC and use a 240-pin desktop form factor.

Check your NAS model and slot count

Verify that your unit is an ASUSTOR AS7009RD or AS7012RD before ordering, as compatibility is limited to those systems. Confirm how many DIMM slots your chassis provides and whether any are already populated, because the kit occupies two slots. Ensure the existing memory, if any, matches the DDR3 1600 specification so the system can run in dual-channel mode.

Thermals noise and power in normal use

The modules run at the standard 1.5 V JEDEC voltage and have no heat spreader, relying on the NAS chassis airflow for cooling. Under typical file-serving workloads the power draw stays low and the sticks add no audible noise. Operating temperatures remain within normal DDR3 limits when the system fans are functioning as designed.

Questions about this item

What comes in the OWC 16GB DDR3 1600 kit and do I need anything else?

The kit includes two 8GB 240-pin DDR3 1600 CL11 1.5V non-ECC UDIMM modules. No extra parts are required for installation in a compatible ASUSTOR AS7009RD or AS7012RD system.

Should I choose this 16GB (2x8GB) DDR3 1600 CL11 kit or a different capacity for my ASUSTOR NAS?

This 16GB kit provides two matched 8GB modules running at DDR3 1600 CL11 1.5V. Select it when your ASUSTOR AS7009RD or AS7012RD supports 16GB total and you want a balanced dual-channel pair.

What does the PC3-12800 1600MHz CL11 rating mean once the memory is installed in my ASUSTOR?

PC3-12800 indicates a peak transfer rate of 12,800 MB/s at 1600MHz with CL11 latency. In your ASUSTOR AS7009RD or AS7012RD this translates to faster data access for multitasking and large-file workloads.
