ASUSTOR NAS Memory by OEM Part Number

Memory upgrades for ASUSTOR NAS systems matched by the ASUSTOR memory part number printed on the module or on your invoice — AS-4GD4, AS-8GD4, AS-16GD4, AS-32GD4, AS-8GECD4 / AS-16GECD4 / AS-32GECD4 (and the -U UDIMM versions), AS5-RAM4G / AS5-RAM8G, AS6-RAM4G / AS6-RAM8G, AS7-RAM4G / AS7-RAM8G, AS7R-RAM4G / AS7R-RAM8G (EC), and the DDR5 AS-8GD5 / AS-16GD5 / AS-32GD5 / AS-48GD5 and ECC AS-xxGECD5 line. Each listing is the specific DDR3, DDR3L, DDR4 or DDR5 module ASUSTOR specifies for that part, in the capacities the platform supports. NEMIX RAM researches, matches, and compatibility-tests each module against the ASUSTOR platform it is listed for, with a lifetime replacement warranty and US-based support.

Every ASUSTOR model from the AS50/51/61/62/63/64 series through NIMBUSTOR, LOCKERSTOR, LOCKERSTOR Pro, FLASHSTOR and the AS70 rackmounts has its own page with the exact module, slot count and maximum for that unit — see ASUSTOR memory by model. The current DDR5 LOCKERSTOR Gen3, FLASHSTOR Gen2 and LOCKERSTOR R Pro Gen2 units are listed on this page.

How to choose

Match the ASUSTOR part number on your existing module, or check the memory type in the ASUSTOR spec sheet (most desktop units take non-ECC SODIMM; LOCKERSTOR Pro and rack units may specify ECC), then pick the capacity. Not listed? Contact us with the model number and we will match the module.
