Compatible NAS upgrade

This 2 GB DDR3 SODIMM is built for ASUSTOR AS-602T, AS-604T, AS-606T and AS-608T units. It runs at 1333 MHz with CL9 latency on a 1.5 V unbuffered 204-pin module. The single-rank 1Rx8 design meets JEDEC and RoHS standards for a warranty-safe installation.

Replaces factory 2 GB stick

It directly substitutes the ASUSTOR AS-RAM2G part when the original module has failed or when a matching stick is needed for dual-channel operation. The upgrade is worthwhile only if the NAS reports a memory fault or the workload demands an identical second module.

2 GB single-module limit

The kit provides exactly 2 GB of non-ECC capacity in one slot. It handles light file serving and basic multimedia tasks but runs out quickly with virtualisation, heavy transcoding or large ZFS pools. Buyers who want more storage or larger memory arrays need higher-capacity modules or additional slots not addressed by this part.

Questions about this item

Will this 204-pin DDR3 SODIMM fit the memory slot in my ASUSTOR AS-604T?

Yes — the module matches the 204-pin DDR3 SODIMM form factor required by the AS-602T, AS-604T, AS-606T and AS-608T series.

What is the correct way to seat the module, and which step do people often miss?

Align the notch on the gold edge with the key in the slot, press the module in until the contacts are fully hidden, then push down until the side clips snap into the notches on both edges.

Does this 1.5 V non-ECC DDR3 module need any firmware updates or periodic replacement after installation?

No firmware update is needed; the JEDEC-standard 1.5 V DDR3 module runs without maintenance, and OWC provides a limited lifetime warranty with free technical support.
