S15E34 - Intel's XTU and You - An Overclocking Approach on an Intel Core Ultra 9

WARNING! This is very long it's not a "How To". But, we look at questions that the YouTubers don't put in one place (and possibly for good reason - this isn't complete by any means and its long). It's pretty much a full walk-through how I did the Beast. I'm sure there are direct take-aways, but it's intended to be more about how to think while obtaining your goals on your system. It isn't perfect nor anywhere near complete, but I tried to help with the attack angle. And I compressed as much as I dared.

Some topics covered: What really is undervolting and when to use it? Why would you not want to undervolt? How can I leverage XTU as a overclocking novice? Why would I ever overvolt and what is that good for? What about speed shift? How is the Core Ultra 9 laid out? We benchmark a little and use Cinebench 2024 to stress test the CPU. What do the BIOS presets do and how can I discover what my BIOS is actually doing when I click or chance something with a preset. © 2025 Del Hollow Productions LLC
