5x 1080 TI on linux

[fl0at0xff]

I just installed CUDA SKA with the following commands:

Code:

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/11.7.0/local_installers/cuda-repo-ubuntu2004-11-7-local_11.7.0-515.43.04-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2004-11-7-local_11.7.0-515.43.04-1_amd64.deb
sudo cp /var/cuda-repo-ubuntu2004-11-7-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get update
sudo apt-get -y install cuda

After a reboot, seems better

Code:

hashcat (v6.2.5) starting in backend information mode

* Device #4: Outdated POCL OpenCL driver detected!

Additionnaly to my problems, I had to change the risers used. The previous guy who mounted this RIG for mining used bad quality risers and powered them like a bitch using cascading SATA/MOLEX connector ...

I replaced these riser with high quality one and powered them only using PCI.
