Hi, what is the gpu utilization? When I run oclHashcat on my two 7970s I never get above 85%. I don't have anything else running that could use the gpus except for the x11 server that is required to initialize the cards.

For example:
- if you use -a 0, -a 1 or -a 6, make sure the base dictionary (left) has at least 10 mio words (per gpu).
- if you use -a 3 or -a 7, make sure your left mask keyspace > 500k entries (per gpu). for -a 3, this is the keyspace of the first 4 chars of your mask.
- make sure your modifier (right) iterates at least through a keyspace of 1k. in case if -a 0 its the number of rules, in case of -a 1 and -a 7 its the number of words in the right dictionary, in case of -a 6 its the keyspace of the right mask.
The workload modifiers are set to low.
If you dont care about screen lags, raise -n and --gpu-loops. For example -n 160 --gpu-loops 1024.

Also disable integrated gpu if it exist on mobo, disable-remove crossfire.
