Abstract
The aim of this article is to study the asymptotic stability of the associated primes of the graded pieces of a non-standard multigraded module. In the most general case, we can assure stability for degrees in every sub-net of a cone in ℕr. As a consequence we prove the stability of the depth of these components in every sub-net of a cone in ℕr.
