Per-Pin Sensing for 5080/5090 Astral Cards

[stefan-it]

Hi guys,

I am highly interested in getting per-per sensing information on Linux.

So for example the new Astral 5080 and 5090 cards from Asus offer a per-pin sensing via the GPU Tweak III software, see here.

Now I am really curious, how Asus did that. I could not find any information using nvidia-smi -q tool, so how is it possible to get that sensor information?

Many thanks in advance!

I don't believe per-pin sensor reporting was ever supported officially. The nvidia-smi utility uses the NVML API to get sensor information, and it does not support anything like this. In fact, even basic core voltage support is being dropped. This is a feature added by an AIB partner (Asus) and not by Nvidia. You would need to ask Asus if they have a documented API to access that information.
