Hey. I've already done a bit of looking around, but nothing's helped me so far. I'm wondering if/how it's possible to increase my GPU usage whilst running dictionary attacks.

I have a 780 Ti. When running an attack on a plain MD5 with an ~800mb dictionary, my GPU usage sits at around 20% and my GPU's temperature doesn't move around much. I've tried messing with --gpu-loops / --gpu-accel etc but they don't really seem to be doing much. I'm only getting ~11800 kH/s, and correct me if I'm wrong, but I think I should be getting a lot higher than that.

Any help appreciated, thanks.

EDIT: I'm pretty sure the only way to fully optimize your GPU whilst running dictionary attacks is to run them with a rule or run a hybrid attack etc. You can close this. Sorry.

you'll never gain full acceleration with straight dictionary attacks against fast hashes on gpu. for straight dictionary attacks against fast hashes, use the cpu instead. or use the gpu but add rules, combinator, hybrid, whatever.
