PTX error when launching hashcat - Kajpio - 03-23-2020

Hi,

I have used hashcat in the past and never encountered any error. After a few years, I reinstalled hashcat, CUDA and OpenCL on Manjaro.

When I launch hashcat like this :

Code:
./hashcat -m 2500 -a 0 hash.txt dicts/rockyou.txt --potfile-path found.txt -O

I get the following error:

Code:
Watchdog: Temperature abort trigger set to 90c

cuLinkAddData(): a PTX JIT compilation failed

* Device #1: Kernel /home/kajpio/development/hashcat/OpenCL/shared.cl link failed. Error Log:

ptxas application ptx input, line 9; fatal  : Unsupported .version 6.5; current version is '6.4'

ptxas fatal  : Ptx assembly aborted due to errors

* Device #1: Kernel /home/kajpio/development/hashcat/OpenCL/shared.cl build failed.

I looked up on google and understood it has something to do with the ptx assembly ? I am not sure what is it and how should I fix the fact I have the wrong version of it.

Thank you very much for your help,

Kajpio

You could try with beta from https://hashcat.net/forum
You could test this guide: https://hashcat.net/faq/wrongdriver

You should give more information about hardware etc

Only newer versions of hashcat use CUDA (beta at the time of this writings)... you could see the different devices with

hashcat -I

the output will distinguish between OpenCL and CUDA

Thank you for your answer ! I didn't know I downloaded the beta of hashcat, I thought it was the stable release on github. I checked out there is no big speed improvement with CUDA compared to OpenCL. If you confirm that, maybe I will just download the latest stable binaries and build them.

Here is the output of

Code:
hashcat -I
