I posted on another thread on my RTX PRO 6000 workstation edition RTX PRO 6000 Blackwell Workstation Ordered - #52 by level1mo
Some highlights
Use a good cable folks
Installed drivers on Windows with Nvidia App. Installed on Fedora with their RPM Fusion nvidia package and using akmod to build with the open source kernel module
sudo sh -c 'echo "%_with_kmod_nvidia_open 1" > /etc/rpm/macros.nvidia-kmod'
sudo akmods --kernels $(uname -r) --rebuild
# very important to wait for kernel modules to fully compile, so I use this command to make sure everything compiled before I rebooted
watch -n 2 "ps aux | grep kmod"
More info in the original posts I linked to above.
