Undervolting my GPU dropped temps a lot

Spent most of the weekend on this and I am still not sure I understand it. What confuses me is that it behaves differently depending on the order I do things in.

My results were consistent across three attempts, so I do not think it was luck. I will report back once I have tested it properly.

Speaking as someone who got it wrong initially, the defaults are conservative on purpose, so there is usually headroom to gain.

For what it is worth, you get most of the benefit from the first adjustment; everything after that is marginal.

Same boat here. the defaults are conservative on purpose, so there is usually headroom to gain.
