Hi,

first thanks for this great program.
When i buy gtx 480 i was really curious for results for this card and there it is :

C:\Users\.....\Desktop\CUDA-Multiforcer-Windows>CUDA-Multiforcer.exe -c charsets/charsetfull -f test_hash_files\test.txt -h MD5 --min 10 --max 14 -
-autotune

Is there any way how set full 480 cores what this card have or to do any improvement for better performace?

W7 x64, drivers 197.55, qx9650 - 4 ghz.

Use the 0.7 release. Performance is much better, though autotune is broken.

Try '--threads 512 --blocks 512 -m 500' - this will make the GUI unusable, but should be very fast.

I do not yet have a 470/480 to play with to optimize for it - if it has a functionality I believe it does but have not yet learned how to access, it may be MUCH faster.

Nice one. Thanks

Awesome. Glad to see numbers.

... now I should buy myself one and optimize. I was looking over the code yesterday and I think I can improve plaintext gen a bit, and possibly searching a bit.

Have to post video, as I do not think anyone would believe these numbers!

What are you so happy about ?
It's JtR style password measurment, i.e. not actual.
You can do a simple test:
Bruteforce [6;6] keyspace using all-space charset.
Now, after the work is done, divide the combinations(95^6) by time taken and you'll get real speed.

That's actually a terrible rate. 240M steps per second is your "actual" search rate. A GTX260 can do better.

Try again with the following parameters:

Code: Select all

--threads 512 --blocks 512 -m 500


Optionally, add "-l" if you have a large hash list, it improves performance on a large list.

Wait can someone on the GTX480 try

Code: Select all

-l --threads 512 --blocks 64 -m 500

and

Code: Select all

-l --threads 512 --blocks 60 -m 500

and

Code: Select all

-l --threads 512 --blocks 15 -m 500

and post the results plz

New hotness:

./CUDA-Multiforcer -d 1 -l -h NTLM -f <FILE> --min=8 --max=8 -c charset/charsetfull -o <Output File> --threads 512 --blocks 60 -m 500

14317 Hashes loaded
Step Rate: 1464.0M/s
Search Rate: 20961239.1M/sec

Running much faster! Thanks! This will shave about 15 Days off my search!

That looks a lot more right for a 480
