Hi folks,
For some reason, my hashcat can use only GPU, CPU seems to be "not available". Hashcat does not see it within the available devices.
Do you have any clue why? My CPU isn't old (i9-9900KF), and drivers should be up-to-date. I tried to explicitly enable it along with GPU using a parameter "-D 1,2" and also with "-d 1,2" ) for benchmarks in any combination, but without success.
Code:
[ 9:55:56] C:\hashcat-5.1.0>hashcat64.exe -m 0 -D 1,2 -b
hashcat (v5.1.0) starting in benchmark mode...
Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

This may cause "CL_OUT_OF_RESOURCES" or related errors.

Thanks, I've downloaded it, installed, then I rebooted PC, and now I got only CPU listed, the GPU is missing ... not sure if it's funny or not
. Did I do anything wrong? This situation is weird to me, perhaps maybe it got something to do with the windows registry or something like that....

Please install the nvidia driver directly from
https://www.nvidia.com/Download/index.aspx

Perfect, this worked! After installation of latest GPU Drivers I can see now both devices (CPU & GPU) listed correctly :
