Hashcat won't use my GPU.. - FuNkO - 02-19-2021
OS Linux Mint 20.1
GPU RX 570
I have installed the latest ROCm drivers for my GPU and when I do the hashcat -I command this is what it displays...
Code:
root@rob-System-Product-Name:/home/rob# hashcat -I
hashcat (v5.1.0) starting...

ATTENTION! Pure (unoptimized) OpenCL kernels selected.
This enables cracking passwords and salts > length 32 but for the price of drastically reduced performance.
If you want to switch to optimized OpenCL kernels, append -O to your commandline.

[s]tatus [p]ause [b]ypass [c]heckpoint [q]uit =>I have tried to uninstall POCL but everytime I do that it automatically uninstalls hashcat?
Help would be very much appreciated.

first: -> never use --force
second:

this is an older version, try downloading, compiling and using the gitversion (v6.1.1***)
third:
amd on linux seems littel bit tricky, see this thread

You need to remove POCL first then install the proper drivers.

I think I am having a similar issue. It seems to see my AMD Threadripper but not the GPU's. Both are slotted in PCIE 3 slots ( At least I am fairly certain they are). Any ideas?
Ubuntu 20.04 (fresh minimal install)

Threadripper 1950X
amdgpu 21.2.6 (open source)
ROCm 5.4.1.50401-84~20.04
