    Thread: mask help
Post: RE: mask help

When incrementing, your mask needs to be as long as your increment maximum, so your syntax needs to be adjusted accordingly: ?d?l?l?l?l?l?l?l And yes, anything you can do to narrow it down will ...

Post: RE: Hashcat 1080(s) gpu error

Could be a power issue. Have you audited real-world power draw from the wall for each PSU under various workloads? How is the power balanced across the board and GPUs?

Post: RE: Hashcat 1080(s) gpu error

Hmm - that seems like enough headroom to me, on each power supply. With ~180W max per 1080 that's only 540W plus 460W for your mainboard, which seems like plenty. Only other thing I can think of: I...

To clarify: adding command-line options to a restore process generally doesn't work very well. You have to modify the restore file manually. I recommend making a backup copy of it first. The script th...

GPU is usually better. There's no way to use more memory at the hashcat level. Some background on the 25% memory cap is here (https://devtalk.nvidia.com/default/topic/992502/cuda-programming-and-per...

You'll need to be realistic about your odds.  You can improve them a bit, but it will take some work. Office 2013 hashes are extremely slow. On my GTX 970, I only get about 4000 hashes per second ...

What is the use case for wanting this behavior? If it's for a reason like this (https://hashcat.net/forum/thread-6293.html), it's not a good one. :) Within hashcat itself, you have four options for ...

I don't know a lot about Mac hardware, but I would assume that this is because the GPU in that unit is slower than the CPU? In my experience, the GPU is usually better, though, so someone else may kno...

Also note that the "maximum power" you mentioned early is memory size, which has no relationship to speed.

In the posted benchmarks, your GPU performance is roughly an order of magnitude better than your CPU performance.

You said your CPU was better than your GPU. This is not correct. Your GPU is much better. How much RAM you're using only matters when using large lists of rules, etc.
