Hashcat see only 1 gpu - AMD RX470 rocm

[technobro]

Hi guys ,


EDIT : i forgot to mention this is an old mining rig i just bough used

After 5-6 format i finally got rocm to cooperate . reading the FAQ ... etc

I can now run hashcat and it see the gpu , but it only see 1 . there are 5 gpu in the machine

Now my understanding is that before with amd driver we had to do this command to for hashcat to see them all

Code:

amdconfig --adapter=all --initial -f

I was hoping somone can enlight me on that. thanks


the card are RX470 and RX570 and the cpu G4400

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.
