OWC 4GB DDR3L 1866 SODIMM for ASUSTOR NAS

This OWC memory module delivers 4GB of DDR3L capacity at 1866MHz with CL13 latency. It is built as a 2Rx8 unbuffered SODIMM operating at 1.35V for the listed ASUSTOR NAS models.

Check your NAS model and slot count before ordering

Verify that your unit is an AS5104T, AS5108T, AS5110T, AS6102T or AS6104T and that a 204-pin DDR3L SODIMM slot is free. The module is non-ECC and unbuffered, so it must match the system's memory architecture exactly.

JEDEC and RoHS compliant with no heat spreader

The stick meets JEDEC standards and RoHS requirements for a warranty-safe upgrade. Its low-profile 204-pin design fits tight NAS chassis without a heat spreader, allowing straightforward insertion and removal during maintenance.
