hashcat Forum

I have a GTX970 with the newest drivers and I installed the CUDA SDK. When using -m 500 or -m 1800 I get the following output and then it exits. Am I missing something with the setup? The token length is ok as I have two different hashes in the same file so its skipping the one of the opposite mode.

Thanks in advance.

ATTENTION! Pure (unoptimized) backend kernels selected.

Using pure kernels enables cracking longer passwords but for the price of drastically reduced performance.

If you want to switch to optimized backend kernels, append -O to your commandline.

It would probably help if you were using the 970, but you aren't in that paste, you are specifying that it try and use your CPU instead. Remove -D1 and try again.

Without the -D it seems to try to use device 4. Is that possibly due to running something else using the GPU? I see #4 during the initializing backend runtime step. It also seems to hang there for awhile.

edit: using -d 1 chose the GPU and seemed to work ok.
