7.1.2 slower than 6.1.2 for SHA512

[zamgold]

OK, please run again command on 7.1.2, add to command line: -n256 -u128 -T128 --force

that didn't help

But it can help us. Could you paste the output for the test Jens asked you to do? Thanks

No problem. My command and output:

./hashcat -n256 -u128 -T128 --force -m 1800 -a 0 1800.hash /media/ntfs1/dictionary/dict.dic

hashcat (v7.1.2) starting

You have enabled --force to bypass dangerous warnings and errors!
This can hide serious problems and should only be done when debugging.
Do not report hashcat issues encountered when using --force.
