GTX 670 Issues with oclHashcat-plus - pandaologist - 07-13-2012
Hi,
I am having troubles running v0.81 oclHashcat-plus on a GTX 670 w/ v295.59 Nvidia drivers under Arch Linux x64. I have no issues running oclHashcat-lite.
oclHashcat-plus will run successfully for a few seconds and then stop. It remains possible to request status updates, pause and resume, the quit command will not work. Status updates after it has stopped demonstrate that progress has ceased as this figure remains static but the time and speed alter accordingly.
Code:
./cudaHashcat-plus64.bin -m 1400 -r rules/best64.rule hashes.txt wordlist.txt

if you have parallel aticonfig --odgt --odgc to check GPU load and temp, can you see that after keying 's', GPU suddenly goes down to NULL%
if you don't key 's' ochHascat+ caries on with the work until work load ends?
You would be the third reporting this status screen behaviour... only from a different angle.
Seems that window users do not have this problem

sounds like a fade-out-wait-because-of-to-small-dictionary. try to reproduce with larger dictionary. see if it happens only on the end

It seems that it still never ends if I never press the status button. If I am quick it is possible for me to get a few status updates before the program stops working properly.

Running with no rules and a dictionary of 37m words, it still freezes:

looks good for me. remember that you can not efficiently run fast hashes like sha256 without an mutation amplifier on gpu see here: https://hashcat.net/wiki/oclhashcat_plus#background

It may not be efficient but surely it should not freeze indefinitely? It should still finish, but for me it does not.
RE: GTX 670 Issues with oclHashcat-plus - atom - 07-15-2012
yeah, but freezing is mostly caused by hardware problem. plus requires much more memory on gpu than lite, so maybe there is a problem

Well I can successfully run the same attack on a GTX 260 with less than 1GB of onboard memory, but the GTX 670 has 4GB. I will see if I can check how much memory is being utilised by Hashcat later.
If you honestly think that maybe there is something wrong with my graphics card, do you have any suggestions on how I could test it? I haven't had any issues with any other CUDA applications or intensive GPU benchmarks.

The graphics card is using 132MB of onboard memory. I guess it might just be a dodgy card. Time to RMA it I guess.
Thanks for all the help by the way
RE: GTX 670 Issues with oclHashcat-plus - th3l0b3 - 08-06-2012
i have the same card. I am running this in Windows but for some reason, cannot get more than 15k in speed for WPA/WPA2. any way i can boost this up a bit?

Any help to get me boosted up to faster speeds on this? I mean i figured with over 1000 CUDA cores, i would be going about 50k at least
