hashcat Forum

Hi,

I'm a newbie with hashcat. I was looking for some tips to how to increase the gpu consumption from hashcat but I didn't get it.
I'm using hashcat and the gpu used is 30/35% even in the report from hashcat is the 100%, I want to double it if is possible.

The comand line is:

hashcat.exe -m 11200 -w 4 brute.hash -a 3 -1 ?l?u ?1?1?1?1?1?1?1?1


The status is:

Really thanks if someone spends some time for me

add this to your command:

what do you mean by 30/35 % . Where do you see this ?

The output of hashcat says:
Temp is 64c
Fan is 37 %
Util is 100%

If you are talking about something you see in your windows task manager etc. it's not the real GPU utilization. The windows task manager is only able to deal, capture, analyze the performance and utilization of well-known and very few windows programs (like browsers, media players, very few video editing software etc). For some reasons it doesn't really query the driver about the real utilization, but just does it's own ( operating system ) analysis of very few "important" software. Unfortunately, many windows users are confused by this strange reporting of windows.

BTW: you can use any other "professional" monitoring software and you will of course see the 100% utilization like in hashcat (tuning software like afterburner, GPU-Z etc)

Really thanks!
This helped me so much, I didn't know that windows problem. I trusted task manager because the fans never goes at 100% speed or close of it and I thougth was a problem from hashcat but your message allows me to search the problem in other places and I found the graphics card profile that was a little weird. Now I changed some configurations and oc the GPU a little bit. Really thanks!
