ASUSTOR NAS Memory Upgrade Kit

This OWC kit supplies 8GB of DDR3 ECC UDIMM memory in a matched pair of 4GB modules. It is built for the ASUSTOR AS7009RDX and AS7012RDX network-attached storage devices. The modules run at 1600MHz with CL11 latency and 1.5V operation. ECC support helps maintain data integrity in storage workloads.

Compatibility and Slot Check

Confirm that your NAS model is either the AS7009RDX or AS7012RDX before ordering. These systems accept 240-pin unbuffered DDR3 ECC UDIMMs. Verify how many memory slots your chassis provides and whether any are already populated. The kit includes two modules, so two free slots are required for the full upgrade.

Build Integration

The modules install directly into the NAS motherboard DIMM sockets without additional cables or brackets. No heat spreaders are fitted, so clearance inside the compact NAS chassis is not affected. Adding this memory frees the system to run more concurrent services and larger file caches. Buyers needing capacities beyond 8GB or a different memory generation cannot use this kit.

Questions about this item

Does the kit include both 4 GB modules or must I buy a second stick?

The upgrade kit contains two 4 GB DDR3 ECC UDIMM modules for a total of 8 GB, so nothing else is required.

Should I choose the 2Rx8 dual-rank version or a single-rank alternative?

The kit uses 2Rx8 dual-rank chips at CL11, matching the ASUSTOR AS7009RDX and AS7012RDX specifications; no single-rank option is offered.

Will the 1600 MHz PC3-12800 rating run at full speed in my ASUSTOR NAS?

The modules operate at DDR3 1600 (PC3-12800) with 1.5 V and CL11 latency, the exact speed grade validated for the AS7009RDX and AS7012RDX.
