Compatible ASUSTOR NAS Upgrade

This 4GB DDR3L SODIMM module is built for ASUSTOR NAS models AS5002T, AS5004T, AS5008T, AS5010T and AS5102T. It runs at 1866MHz with CL13 latency and a low 1.35V operating voltage. The unbuffered, non-ECC design matches the original system specifications exactly.

Suits Single-Slot Capacity Boost

Ideal for owners of the listed ASUSTOR units who have a free 204-pin slot and want to add 4GB of memory. It will not help systems that require ECC registered modules or a different DDR generation. Buyers needing higher densities per slot or faster speeds must look elsewhere.

4GB Module Headroom

A single 4GB stick handles typical NAS workloads such as file serving, backup jobs and light virtualisation. Performance tapers off when multiple heavy containers or large metadata databases run simultaneously. The 2Rx8 organisation provides standard bandwidth for the platform.

Questions about this item

Does my ASUSTOR NAS need a free 204-pin SODIMM slot to add this 4GB DDR3L 1866 module?

Yes, this module uses the 204-pin DDR3L SODIMM form factor and requires an available slot in a compatible ASUSTOR model such as the AS5002T, AS5004T, AS5008T, AS5010T or AS5102T.

Can I keep my existing DDR3L memory and run it together with this CL13 1.35V stick?

The module follows JEDEC DDR3L specifications at 1866 MT/s CL13 1.35V; if your current memory matches those ratings it will run alongside this stick at the common speed and voltage.

How can I confirm the new 4GB module is recognised at 1866 MHz after installation?

After powering on the NAS, check the system information or resource monitor in the ASUSTOR ADM interface; it should show the additional 4GB and report the memory running at 1866 MT/s.
