Hello everyone,
I am in need of some help. I am running oclHashcat-plus64.bin in Ubuntu 10.04. I have 2 HD6990 cards and am trying to crack a WPA/WPA2 password. Everything is running smoothly for a couple of minutes, then the whole computer freezes and needs to be restarted.
Before I start cracking I set the fans to 75%. This keeps the GPU cores to a maximum of 75C. I have a 1200W power supply and I have checked to make sure that the cards does not require that much power. They only reach around 800W. The power consumption drops to around 200W at the moment the computer freezes.
I have tried leaving one core out of it (-d 2,3,4), but the same thing happens.
The exact command I am running is:
./oclHashcat-plus64.bin -m 2500 fourwayhandshake.hccap wordlist.txt -n 80 -gpu-loops 4096 -r rules/perfect.rule
The computer is working fine otherwise. I can play games with it and I have mined bitcoins with it for many days in a row without any problems.
Does anyone have any idea of what is wrong or what I could try to make it work?
