So I'm dumb and lost my ETH password

It took more time before failing(about 30 seconds), but didn't work.

The other 2 pc doesn't like it better, yet all driver are up to date (only copied one of the 2, since they produce similar return):

I just learnt script-tmto=0 means auto-configuration, not disable tmto trade-offs alltogether. And furthermore, the higher the value the less RAM is used.

However, there might be an incompatibility with the ethereum2john.py script and hashcat's hash parser. I'm waiting for someone who knows the technicalities to check on that. Hopefully someone will post an update here soon. edit: it probably works as expected according to my tests

Wow!I can see that the situation has got intense for a noob\dumb user!

[undeath]

take home message: the scrypt settings ethereum uses by default make GPU cracking mostly impossible. Just use your CPU.

[DumberThanDumb]

I read that gpu related notice before, but I also saw people get about 30h/s with the 1080 on eth scrypt, so I thought it would simply not be able to give the awesome gpu performance yet still faster than the cpu for each 1070. Since I have a 6x gtx1070 I wanted to try it but guess I will simply stick to cpu.

Thanks for all the help!

[undeath]

scrypt has three parameters. Depending on how those parameters are chosen it may or may not work on GPU. The parameters of your ethereum wallet don't.
