Do you have a good tutorial for this ?

I need to do the same to my 4080 super. Performance is penalized by thermal throttling atm.

There are loads of videos on YouTube which showcase GPU undervolting, such as this one for example. You may want to look for one that specifically targets the RTX 4080 Super.

Something to keep in mind: how well a GPU undervolts depends on the silicon lottery. Also, it can take a lot of trial and error to find a stable undervolt value, but the end result is definitively worth it.
