CudaHashcat64 doesn't recocnize GPU? - jordiadr - 12-06-2014
Goodday,
I wash trying out Cudahashcat64 on my windows 8.1 64 bit system with cudahashcat 1.31.
It seems like it is not recocnizing my GPU
GPU is: MSI Nvidia Geforce 660 TI PE OC
Using this command: cudahashcat64 -m 2500 -a 3 c:\Directory\out.hccap ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a
This is what I get using that command after that I pressed s for status.

Anyone has an ID?
CMD was launched as an admin. Drivers are up to date.

Looks like it's working just fine to me. You can see GPU #1 right there, and it seems to be running just fine.

Seems he saw > 10 Years and thought it's on CPU

More than likely. Let's see,
95^16 / 51024 / 31556926 ~= 27334333654499028403 years
Good luck!

Thanks guys and yeah something like that lol haha
I guess Ill be buying a Ati next time than.

Still won't help you much. Let's see, R9 290X can pull 180 KH/s on WPA...
95^16 / 180000 / 31556926 ~= 7748372446595324585 years
Hopefully by this point you are realizing that you're not going to be able to brute force a 16-char password.

I see thank you for the math that is not my thing.
Now I am trying to run it with increment options.
Using this command: cudahashcat64 -m 2500 -a 3 C:\Users\Jordi\Desktop\out.hccap ?a?a?a?a?a?a?a?a?a?a?a?a -i --increment-min=8 --increment-max=12
It this the right way to execute the command or am I doing it wrong again?
And is there a device that can be used in hashcat that has astonishing speed results?
Some hash calc device? like the bitcoin mine machines.
Thanks in advance.

Your syntax is fine, but that command isn't really plausible. GPUs are not magic. WPA is very slow. Doesn't really matter how many GPUs you have, brute force is not really feasible with WPA. To brute force even an 8 character password in one week, you would need...
95^8 / 604800 / 210000 ~= 52235
... a cluster of 52,235 R9 290X. (Sorry, I used 180 KH/s in my previous calculations which was incorrect, that figure was based on old benchmarks. 290X can pull 210 KH/s with 1.31.)
No, you cannot use Bitcoin ASICs with Hashcat. They are specific to Bitcoin.
