Greetings all! My rig has 3 graphics cards in it and due to cooling issues, I changed 2 of them to have hybrid cooling. So I start rerunning some cracking tests specifying to use only those two cards and not the one with stock cooler.
I noticed when I specify devices, the utilization shows as 100% on one but 0% on the other. Below is a censored version of the command I used followed by Hashcat output. Is this a bug or is it expected behavior and I am maybe missing something?
Also - i noted my cracking performance is about 1/3 that of when running the benchmark. Is this an example of when I need to generate work? I thought it would not be the case as I am doing pure bruteforce and the need to generate work comes with performance loss when waiting on the wordlist to copy across the pci-x bus. If I am incorrect, happy to be pointed in the right direction.
