Hashcat don't use my GPU or my GPU are bottleneck - .Griff - 06-05-2020
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:4Also 18826 MH/s is very nice.
But when I want to use to decrypt my 5 rows hash :
Code:

Hardware.Mon.#1..: Temp: 52c Fan: 0% Util: 14% Core:1582MHz Mem:3802MHz Bus:16The 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.txtI 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
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
RE: Hashcat don't use my GPU or my GPU are bottleneck - royce - 06-05-2020
Wordlist-only attacks (without additional work like rules or hybrid masks) cannot reach full benchmark speeds, because not enough work (candidate words) can be supplied to keep up with the speed of the GPUs.
You can supply more work by using rules (-r), or other attacks. See the hashcat wiki for more ideas.

Okey thanks ! I will try with the (-r)
