Only 3/8 GPU used

[ssjtoma]

When I had 3 GTX 480 gpus, some weren't always used.
Turns out it's about combinations on the left side.
Try ?1?1?1?1?1 ?1?1

Thanks, that did fire up the rest of the GPU's as well, but the performance is no better then when it only used 3:

EDIT:
cudaHashcat-lite seems to be using 6 of the GPU's and has much superior speed then cudaHashcat with all gpu's. Weird:
