Please verify the Model number.  I don't find a G3 3570 on the Dell Support site or the Crucial Memory site (that I was going to link you to). Could it be a 3590?

Mixing memory brands usually results in problems.  Only have one brand/type (and correct memory).  Where you are located (USA or Hong Kong) has no bearing on what memory works or does not work.  Dell has a history of not working with non-Dell branded memory .  We usually suggest Crucial as it is one brand that is guaranteed to work in a Dell but I need the correct model number.

Look it up on the Crucial website https://www.crucial.com/products/memory/laptop-dram

Yes, it should be 3590. Thanks.
