If someone has already undervolted their laptop, please tell at what exact point should I set to undervolt the CPU? I want to use Intel XTU

    If you want assurance, then it's better to do a stress test with different voltages before applying them. I am not familiar with stress testing but its instructions are easily available on the web. The stable limit varies from model to model.

    If you just go by estimated values, you'll have trouble later. For example my 515-51 used to work alright most of the time on -128, a value I set without testing. But a few select games would regularly crash. I figured out that the undervolting could be the issue and changed it to -124. It did not crash anymore. My point is that different applications can have different needs and impact on the PC. You may not know it till you use such a one. Which is why stress test is recommended.
