Third chain in the life of that cassette? Or the third chain you've tried and they all exhibit this issue?
If three chains for one replacement period then I'd think you've spent the cost of a cassette. So try it.
If you've replaced two other chains at normal intervals and this it the third time, then that cassette is probably worn out along with the chain rings maybe.
We don't need to ask if you used the correct speed chain do we?
