No GPU utilization - tinman - 12-02-2012
I am trying to run some md5 hashes through the gpus. The hashlist has about 9.5 million hashes and the wordlist from InsidePro has about 154 million words.
Windows 7-64bit 16GB ram, 2x ATI-5770
Option 1 using hashcat-gui:
C:\Users\XXXXX\Downloads\hashcat-gui-0.5.1\hashcat-gui-0.5.1\oclHashcat-plus>oclHashcat-plus64.exe --remove --outfile J:\Hashes\xabout.txt --gpu-devices 2 -m 0 J:\Hashes\xab J:\Wordlists\InsidePro\Master.txt

Option 2 using plain oclhashcat-plus:
C:\Users\XXXXX\Downloads\oclHashcat-plus-0.09>oclHashcat-plus64.exe --remove --outfile J:\Hashes\xabout.txt --gpu-devices 2 -m 0 J:\Hashes\xab J:\Wordlists\InsidePro\Master.txt
Access is denied.
Windows prompt error popup: oclHashcat-plus64.exe is not a valid Win32 application. Of course I tried the 32 bit version but it didn't have enough memory. The md5 hashlist is
For option 1, why is my gpu not getting used at all?
For option 2, how can I run the 64 bit cmd?

it is getting use just not reporting the utilization. otherwise you would have 0 found. for the error, try downloading it again, never seen that problem.

Well that I can guess was just by the cpu. You would think that 2 ati 5770's would get more than 9207 c/s. My cpu gets tons more than that. Also I am using the AMD Vision control center to monitor the activity temps, and fan info and it doesn't get to 1%
EDIT: A redownload of the oclhashcat-plus (not gui) seems to still have the issue that it is not using the GOU, but at least it let me run the oclHashcat-plus64.exe
RE: No GPU utilization - radix - 12-02-2012
oclhashcat-plus does not use CPU. if you are using the gui stop and use just the command line, gui is not supported by us.

you are not giving the card any work to do, that is why there is 0% utilization. if you want to fully utilize the gpu then try adding rules to give the card something to do.

That was my problem. I now show the cpu at 721M c/s and the gpu at 755M c/s for generate rules 20. If I were to say --generate-rules 20 would it do all of --generate-rules 19 and --generate-rules 18? The manual isn't clear on that.
On my use of the rule d3ad0ne the hardware 1 still shows 0%. It seems to only report and use one of my two graphics cards. They are both 5770's and have crossfire. I notice on the AMD control center that card 1 is at 0% and card 2 is at ~95% at 72C.

Dude, the CPU is not cracking your hashes... thats all gpu power

no. you are generating random rules. -g 19 would generate 19 random rules. -g 20 would generate 20 random rules. typically you want to do something like -g 30000.

remove your crossfire interconnect and disable crossfire.

I notice on the AMD control center that card 1 is at 0% and card 2 is at ~95% at 72C.On your command line, you specify -d 2 which means use only GPU2. You have to specify -d 1,2 to get both working. You still need rules to keep them both busy...
