Can i accelerate it?

[pacifiste95]

Hello,

i'm using Cuda-multiforcer on my windows seven, i have the latest driver for my graphic card.

My GPU is Nvidia GTX260M, and i have a Intel Quad core Q9000@2,4ghz.

I'm trying to crack NTLM hash, can i accelerate it?

c:\>CUDA-Multiforcer.exe -c charsets/charsetfull -f hashntlm.txt -o ntlmpw.txt --m
in 9 --max 10 -h NTLM

What do you think about my step and search rate?

Thanks a lot !

try this

CUDA-Multiforcer.exe -c charsets/charsetfull -f hashntlm.txt -o ntlmpw.txt --m
in 9 --max 10 -h NTLM -m 500 -t 512 -b 14 -l

and post the results up

i have this error : Cuda error: too many resources requested for launch.

what can i do ?

c:\>CUDA-Multiforcer.exe -c charsets/charsetfull -f hashntlm.txt -o ntlmpw.txt --min
0 --max 14 -h NTLM -m 500 -t 512 -b 14 -l

[pacifiste95]

This is the same...no?

i have the same error... Cuda error: too many resources requested for launch.

That error basically means you're throwing too many threads at it.

Try dropping the '-t' parameter back to 256. It should fix that launch error. Then play with the block count to optimize performance.

Thanks, for the block count => lower is better ?

[Bitweasil]

Depends on how long you're running it for.

If you've got smaller -m values, a smaller block size is better. It's kind of hard to fully explain... I really should sit down and write up a howto.

All hashes cracked.

I think it's a little bit slow... with a custom block count i can optimize it, and how?

thanks
