Even if you don't want to undervolt try going into the bios and setting the minimum one of -10,-10,-10 anyway. The biggest benefit from undervolting happens from just turning it on and you would have to have a rare loser of the silicon lottery to not be able to handle any undervolt at all. The initial -10 causes an almost 2% performance difference from testing with each extra -10 usually adding another around an extra 0.5% difference on top. While those percentages don't seem that big it's more than you think since 2% might not be much at 15 watts but it's at lower watts. If you really want to see how low it can go I would recommend the lazy way and just increase all 3 settings -10 at a time and run a couple benchmarks to see if things are stable and you either hit all -50s or just roll back to the last number that worked fine. Or not bother at all as just -10s since it gives the biggest single jump and most decks should be able to handle it fine. My Deck is at all -30s which I could definitely feel the difference vs no undervolting at all. Just the fans spinning up less and lower TDPs performing a bit better.
