Guys, I have a few R9 380 2GB GPUs, can they mine ETH?

I know about DAG problem, but someone said that solution is to set prirary gpu with more than 2gb of vram?

I set R9 380 4GB as primarty, and still can't mine with 2gb, actiually i can but hash is 0,7 mhs.

Does someone mining with 2gb cards? Thanks.
