Hello everyone,
I have the following 2 problems with hashcat 3.0 and 3.1:
after having installed a new nvida-Driver (372.54) for my GTX750Ti I launched a 7zip test decryption.
The password was "яliebeтебя" (special for this forum thought out password).
I launched a dictionary attack. The dictionary contains only this word. I created 2 dictionaries: Win1252 and UTF8. Both attacks were unsuccessful.
Code:
hashcat (v3.10) starting...

OK. Then I changed the password in "ichliebedich". Created a new dictionary with this word and launched the attack again.
Now getting the error message: ERROR: clEnqueueReadBuffer(): CL_INVALID_VALUE

Why did I suddenly this error? I have not changed the system (i7-6700 3,40 Ghz, Asus GTX750Ti, Win10 64bit German Home with anniversary update, hashcat 3.x 32/64).

I just tested your hash/plain combination and it also did not work for me, however I proof checked it with phils 7z2hashcat https://github.com/philsmd/7z2hashcat and discovered that there must be something wrong with the way you generate your hashes.

I generated this hash for him using 7z2john.py.
After read your answer, I used the 7z2hashcat.pl and the result was the same.
Please, try extract the hash from the attached file.
Thank you.

FYI My Original file was produced by CryptSync, a 7-Zip implementation http://stefanstools.sourceforge.net/CryptSync.html Zarabatana kindly helped me after I was unable to extract a hash from those files. Hashcat didn't generate errors with any other mask other than the correct one (which helped me solve my problem).

Ok, so far so good. There seems to be an issue with the different ways hashes are obtained. But it seems to generally work for me, as you can see from my potfile:
From the looks of the messages you get in your initial post, it's possible just a matter of your GPU not having enough ram but I don't know enough about the algo to verify this.
