  Thanks for the answer.

  Just checked with lspci -v and it says radeon:

  Is that the one it’s supposed to be active?

  About the allocate thing, I think that is a number and not an index in an array. I think that you can allocate as many gpus you want:

  I’ve seen that same menu in screenshots and I’m supposed to be able to choose something different from zero.

    Since this is GCN based, you may be able to use the newer AMDGPU kernel driver? I’m not sure about that specific SKU, however. I remember that using AMDGPU on, for example, Hawaii (like the R9 290) was particularly finicky

      Not sure how to change the driver to AMDGPU, I blacklisted the Radeon driver but the kernel didn’t load the other one. I read somewhere that I have to do a initframs update but the command doens’t exist in truenas scale. How do I force to load the other driver?

        For that card, you probably have to set the radeon.si_support=0 amdgpu.si_support=1 kernel options to allow amdgpu to work. I don't have a TrueNAS system laying around so I don't know what the idiomatic way to change them is.

        Using amdgpu on that card has been considered experimental ever since it was added like 6 years ago, and nobody has invested any real efforts to stabilize it. It's entirely possible that amdgpu on that card is simply never gonna work. But yeah I think the radeon driver isn't really fully functional anymore either, so I guess it's worth a shot...
