Hashcat don't use my GPU or my GPU are bottleneck
#1
Hi !

I have a problem, I have recently installed Hashcat on my PC ( Win10 ) when I do a benchmark with MD5 I have :

Code:
OpenCL Platform #1: NVIDIA Corporation
======================================
* Device #1: GeForce GTX 1070, 2048/8192 MB allocatable, 15MCU

Benchmark relevant options:
===========================
* --optimized-kernel-enable

Hashmode: 0 - MD5

Speed.#1.........: 18826.4 MH/s (52.75ms) @ Accel:1024 Loops:256 Thr:256 Vec:4


Also 18826 MH/s is very nice.

But when I want to use to decrypt my 5 rows hash : 

Code:
Session..........: hashcat
Status...........: Running
Hash.Type........: MD5
Hash.Target......: .\cracked.txt

Hardware.Mon.#1..: Temp: 52c Fan:  0% Util: 14% Core:1582MHz Mem:3802MHz Bus:16

The command use was : 
Code:
hashcat64.exe -a 0 -m 0 .\cracked.txt D:\[color=#333333][size=small][font=Tahoma, Verdana, Arial, sans-serif]xxxxx[/font][/size][/color]\Documents\Dictionnaire\hashesorg2019.txt

I have test lot of command with "-O" without or with "-w 4".

I have test the mask method with "-a 3" but I have an error and I don't find why I have this error. 

If you have an idea for what I can't use my GPU tell me Smile

Pardon for my english ^^ 

have a nice day



( I have a GTX 1070 with last drivers of Nvidia geforce experience )
I use a 12Gb wordlist
I have install the last CUDA toolkit (https://developer.nvidia.com/cuda-downloads)
I have try the beta of hashcat
I have do that https://hashcat.net/wiki/doku.php?id=timeout_patch
