Hashcat only detect one GPU card

[neodark]

Hi, I have installed Hashcat on a Ubuntu 20.04. I have installed kernel 5.4 generic and uninstalled kernel 5.8. Installed ROCm from this guide (https://rocmdocs.amd.com/en/latest/Insta...tml#ubuntu) and installed Hashcat from apt

With the command "lspci | grep VGA" it detect 4 cards (I have 5 cards RX580... one is "losed")

Code:

root@administrador-H110-D3A:/home/administrador/Escritorio# lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 610 (rev 04) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7) 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7) 05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7) 06:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7)

When I try "hashcat -I" I got this

Code:

root@administrador-H110-D3A:/home/administrador/Escritorio# hashcat -I hashcat (v5.1.0) starting...

Only CPU and one GPU detected by Hashcat... how I can solve it?

Thanks!!

Is not a hashcat issue. ROCm does not support RX cards if not placed on PCIe 3.0 slot.

Also you should disable POCL. If you really want to use CPU, use Intel oneAPI OpenCL.
