OWC 8GB DDR3 1600 Kit for ASUSTOR NAS

This kit provides 8 GB of DDR3 memory in two 4 GB unbuffered UDIMMs rated at 1600 MHz with CL11 latency and 1.5 V operation. It is built specifically for the ASUSTOR AS7009RD and AS7012RD network-attached storage appliances.

Ideal for owners of those ASUSTOR models needing

Buyers who want more storage capacity or who need ECC error correction should look elsewhere because this kit is non-ECC and only adds system memory. Systems that require registered DIMMs or a different DDR generation are also not a match.

240-pin DDR3 1600 CL11 1.5 V UDIMM specification

The modules follow the PC3-12800 JEDEC standard in a 240-pin unbuffered form factor with 1Rx8 organisation. That exact specification determines whether the kit will install and run in the target NAS.

Questions about this item

Does the kit include everything needed to upgrade an ASUSTOR AS7009RD, or must I buy extra parts?

The box contains two 4 GB DDR3 1600 CL11 1.5 V UDIMM modules; no additional components are required for installation.

Why choose the 8 GB (2 x 4 GB) DDR3 1600 kit instead of a single 8 GB module?

The matched pair enables dual-channel operation on the ASUSTOR AS7009RD and AS7012RD, delivering higher bandwidth than a single stick.

What does the PC3-12800 rating mean for everyday use in my ASUSTOR NAS?

PC3-12800 indicates a 1600 MHz data rate, so file transfers and multi-app workloads run faster than with slower DDR3 memory.
