as sugested by hellae on Redit. Getting on average 1925H/S
When using autoconfig for xrm-stak (aio) I get about 2500h/s total for 4 cards. When using above config in xrm-stak I get about 1800h/s per card.
By trial and error, managed to get 7600 (+- 10) H/s using this config

Have not tested it for longer periods, so I don't know if its stable. But still less than older version.
