intel extreme tuning utility undervolt cpu

Notebookcheck assumes no liability for possible damage caused by modifications. We recommend reducing the voltage in small steps and testing every level with the integrated Intel XTU stress test (see following picture), for example. Even identical configurations can behave differently and you should be conservative when you try to find the limit.

Note: The shown values only apply for our specific test models.

We used the free tool Intel Extreme Tuning Utility (XTU) for the following examples. We already explained how this undervolting process works in this dedicated article. This leaves unused potential for optimizations, so you can improve your laptop with some time and testing. Not every processor is identical, so Intel sets a default voltage to make sure the processor works without problems at the designed specs. Today, we are going to have a closer look at the processor core voltage with two examples, the Lenovo ThinkPad X1 Carbon ( Core i7-8550U) and the ThinkPad T480s ( Core i5-8250U). The current ThinkPad lineup alone shows massive differences, as we have seen in this article. We have already tested numerous devices and there can be big differences when it comes to the performance utilization. Intel Extreme Tuning Utility is a simple Windows-based performance tuning software for novice and experienced enthusiasts to overclock, monitor, and stress a system. However, this also results in higher power consumption and higher temperatures. They offer four native CPU cores and are much faster compared to the old dual-cores. Basically, every new ultrabook or laptop released since last autumn is equipped with Intel's new 8th Gen ULV-processors.
