ASUSTOR AS6404T memory upgrade

This single 4 GB DDR3L SODIMM is built to fit the ASUSTOR AS6404T NAS. It runs at 1866 MT/s with CL13 latency at 1.35 V. The unbuffered, non-ECC module uses a 2Rx8 layout on a 204-pin board.

Replaces the factory module

Swapping the original stick for this 4 GB unit restores the system to its rated speed without voltage mismatch. The jump is worth it when the NAS ships with a slower grade or when a slot is empty and the workload needs the extra headroom.

Handles everyday NAS duties

The 4 GB capacity keeps typical file serving, backup jobs and light virtualization responsive. It runs out when multiple heavy containers or large media transcoding tasks compete for the same pool.

Questions about this item

Does the 204-pin DDR3L SODIMM fit the ASUSTOR AS6404T memory slot?

Yes, the 204-pin DDR3L SODIMM form factor matches the ASUSTOR AS6404T memory slot exactly.

What is the correct orientation step when installing the CL13 1.35V module into the NAS?

Align the notch on the module with the key in the slot, press down firmly until the side clips click into place.

Will the 2Rx8 rank configuration require any future firmware update on the AS6404T?

No firmware update is needed; the JEDEC-standard 2Rx8 module works with the existing NAS firmware.
