Earlier I used --interactive=0 --hash-parallel=1 --launch-config=K7x23 --texture-cache=0 --single-memory=0 --lookup-gap=3
I´ve tried several combinations of the other options, but nothing helps. (also batchsize doesn´t seem to change anything for me.)

BTW I want to report a small bug: --batchsize=x isn´t recognized correctly. Only -b x works.
