RE: Nvidia GTX GPU not working - atom - 12-31-2016

Please do update your hashcat version to a newer one, v3.10 is really outdated.

Also 517kH/s on WPA is crazy fast. Better than 3kH/s on my AMD FX(tm)-6100.


RE: Nvidia GTX GPU not working - duhblow7 - 12-31-2016

517.4 kH/s is right on point for that cards benchmarks.  Here is the benchmark I found:

https://hashcat.net/forum/thread-5729-post-30819.html#pid30819

WPA has a 4 way handshake which adds much more overhead during brute force cracking.  This is why it is much slower than say, MD5.

everything is updated but when i get to the installer it says im already running nvidia-dkms, nvidia kernel
and says installation failed

apt-get remove nvidia-dkms  --purge

awesome so im getting almost the same hashrates, but i start to notice that the hashrates fall off to 400ish when the card has been running for a while.

is there a way to tweak the card? (overclock? fan settings?) something like MSI afterburner on windows? or do i have to fiddle with the nvidia kernel files and configs? what should be i be doing?

apologize if this was asked somewhere that i couldnt find.




does anyone know why this is coming up when i run hashcat? is my setup incorrect?

clGetDeviceIDs(): CL_DEVICE_NOT_FOUND



Thanks

RE: Nvidia GTX GPU not working - atom - 01-01-2017

Well that's the problem with the new NV driver behavior they started with 10xx series. The clock rate depends on temperature. You can see this while you're update the status screen once in a while. You will see the clockrate going down as the temperature going up. Unfortionally there's no way to disable this. Not on windows, not on linux.

About the CL_DEVICE_NOT_FOUND is because you have the opencl runtime for mesa installed. Purge it and it will error will be gone, too.


RE: Nvidia GTX GPU not working - duhblow7 - 01-01-2017

guess you're just gunna have to submerge that card in liquid nitrogen then.  Big Grin

thx for that uninstalled mesa-opencl-icd n it workedSmile

damn, so there is no way to config that right now? so sad...

maybe i should invest in a cooler , but maybe not submerging the whole thing just yet duhblow7

FWIW I've reported this to NVida (among others) but they don't care: https://devtalk.nvidia.com/default/topic/978583/1080fe-powersave-frequency-scaling/

i got a different output when i ran the command

nvidia-smi -q -i 0 -d SUPPORTED_CLOCKS
