6x7970 - cards not running at full utilization - flux - 11-07-2014
Folks,
When testing my rig with mysql323 - I could get 97-99% utilization on each card.
I'm now working on some NTLM hashes (trying all upper /lower case with numbers and symbols) and the utilization is way lower. Here is the command and a summary of the utilization:
./oclHashcat64.bin -w 3 -i —gpu-temp-abort=95 -m 1000 -a 3 -l ?l?u?d -o cracked.hashes input.hashes

Am I missing something here? How can I get 98%+ utilization across all of my cards?
Many thnx

There are two errors in your commandline. First one is that you use -l instead of -1 parameter, second one is that you're missing a mask at all. Please read this page https://hashcat.net/wiki/doku.php?id=mask_attack
Once you're mask is setup correctly (and big enought) your utilization will stabilize
