Hey there,
I’ve been playing around with bazzite, love the concept and then I tried to look at undervolting the dGPU with LACT. The kernel flag is correctly set but still can’t get the advanced menu to play with voltage.
I play with the cherger plugged in but I’d like to lower the consumption to lower the heat.
Does anyone succeeded with undervolting ?
Did I miss something beside the kernel flag ?
It would be great if you can share your experience here (bazzite or any other system).
No progress anywhere AFAIK.
I asked about this here a while ago, when I was considering on getting the graphics module and wanted the ability to power limit (& undervolt) so I can still charge while using 180w power adapter and as well as for summers to keep heat manageable, and the response I got indicated that it wasn’t possible due to changes to amdgpu at some point and that 100w is the lowest you can go unless you’re running with a patched amdgpu driver + custom kernel, so I ended up deciding not to grab the module, which is unfortunate.
