GTX 1070 low performance - assafd - 06-20-2019
Hi guys,
I don't know why my machine does not take advantage of GPU card capabilities
I have Lenovo Legion Y720 with nVIDIA GeForce GTX 1070 OS: CENTOS 7 Hashcat 5.1
Im trying to crack NTLMv2 password and the working speed of the card is around 850MHz which is a bit slow....
I'm trying the following conmmand : hashcat -m 5600 -a 3 -d 1 <hash.txt>
The output of hashcat -b is around ~ 19000MHz
In addition the following message appear :
Cracking performance lower than expected?
* Append -w 3 to the commandline.
This can cause your screen to lag.
* Update your OpenCL runtime / driver the right way:

* Create more work items to make use of your parallelization power:

any advice before Im going to reinstall the driver ?

1. running hashcat on notebooks is not recommended
2. you are not specifying a mask
3. did you try the suggestion of adding -w3 and -O ?
4. hashrate is not measured in hertz (lol)

Thanks for your quick answer .
Sorry for the delay . I was on vacation for a week
1- its not a notebook , its a server
2- is it mandatory in order to get more than 64ms speed ?
3- yes , same speed
4-The output is appear in Mhz and also in ms

Lenovo Legion Y720 is a notebook.
"64ms" is not the speed, it's the kernel runtime.
MH/s is not the same as MHz.

Seems weird that you would see the same speed with -w3 and -O. It should at least improve a bit. If it doesn't that may hint to serious heat throttling due to using a notebook. (benchmark is only a short burst workload, hence it doesn't throttle)
