There are some other Guides as well, if this isn't to your liking. Very long but worth the read if you want to use Throttlestop. Make sure to add Throttlestop to Autostart, else you will need to start it by hand after every single reboot.Ī Handy Guide. I have my i7 8550u running at -125 mv without any crashes whatsoever. In my experience you can easily go down by 100 mv. automatically switching profiles and limiting clocks etc. You should take a look at either xtu from Intel itself or Throttlestop, which I recommend, as it has some extra features e.g. I am talking from the Experience with 7th 8th and 9th Gen U Cpus, so keep that in mind. Intel Extreme Tuning Utility XTU 6.1.2.Almost all Intel Cpus of a single Node aka 14 nm behave the same when it comes to undervolting, other than getting slightly better at undervolting each Generation.Intel Extreme Tuning Utility XTU 6.2.0.19.Intel Extreme Tuning Utility XTU 6.2.0.24.Intel Extreme Tuning Utility XTU 6.2.0.27.Intel Extreme Tuning Utility XTU 6.3.0.54.Intel Extreme Tuning Utility XTU 6.3.0.56.Intel Extreme Tuning Utility XTU 6.4.1.11.Intel Extreme Tuning Utility XTU 6.4.1.19.Intel Extreme Tuning Utility XTU 6.4.1.23.Intel Extreme Tuning Utility XTU 6.5.1.321.Intel Extreme Tuning Utility XTU 6.5.1.355.Intel Extreme Tuning Utility XTU 6.5.2.40.Intel Extreme Tuning Utility XTU 7.4.1.3.We are working with Microsoft to resolve this issue. In these cases the user may reboot the system and rerun the XTU installer or application. When Windows Smart App Control feature is enabled, installing and/or running XTU may result in a notification or error from Windows.In certain undervolt protected system configurations XTU will be unable to set voltage controls to system default values.In these cases, XTU is unable to function when these features are enabled.

In certain system configurations, Core Isolation Memory Integrity, Hyper-V, and Virtual Machine State are incompatible with XTU.The software interface exposes a set of robust capabilities common in most enthusiast platforms along with special new features available on new Intel processors and motherboards.
