Intel Extreme Tuning Utility (XTU) Undervolting Guide
Power limit throttling Intel XTU graph showing the Sager NP8275 Intel Extreme Tuning throttle flag being triggered first occurance highlighted. Looking at our test run, we can see that this laptop was throttling due to hitting the power limit before it reached the thermal limits when running a CPU-only workload. Intel XTU graph showing the thermal throttle flag being triggered first occurrence highlighted.
Then monitor temperatures — or the thermal throttle flag — using the graph function in Intel XTU which continually monitors while the software is open. The more extreme Furmark is an option for those who want Sager NP8275 Intel Extreme Tuning check the results with maximum GPU temperature.
Tweak and Test Now is where the fun begins. We will start adjusting the CPU core voltage offset, which moves in increments and decrements of 0. A CPU needs a particular voltage to switch on and to maintain normal operation over time.
Because there is a level of variation in every chip, they are shipped from the factory with a safety margin in their default operating voltage. What we are doing here is slowly removing that safety margin until we find the point where our individual processor is no longer receiving enough voltage to maintain itself Sager NP8275 Intel Extreme Tuning load, and then backing off slightly to maintain stability.

Intel XTU voltage selection drop-down list. Proper procedure is to start making small increments of 5 — 10 mV and testing each setting. Since we want to save time we are going to pick a start point based on our experience, and the experience of others online, where we know it should be safe to start with an offset of As a generalization, many Skylake Core U-series mobile processors seem to find their upper limit between Begin your testing several steps Sager NP8275 Intel Extreme Tuning those levels.
Now change to your starting offset using the arrow buttons or the dropdown list and hit apply. Your computer will have managed to override the new offset you tried to set and will be back to default voltage, but as a matter of caution make sure your starting point is within a realm of possibility.

It is time to test stability under load using the built-in CPU stress test. The reason for this is we want to quickly find the point where it is unstable under any load whatsoever, and 10 minutes is long enough to show this. Later, we will refine our settings and run a more extensive stress test to test stability Sager NP8275 Intel Extreme Tuning.
Keep repeating this process using increments of 0. Sager NP8275 Intel Extreme Tuning this happens, drop back 0. Those who run right on the knife's edge with undervolting or overclocking prefer to run software such as Prime95 or AIDA64 for half a day, but this is more than we need for our purpose. Setting Profiles Optional Once you are happy with the undervolt achieved, hit the save button on the right side and give it a descriptive name.
This area is more useful when using a CPU that allows overclocking because the user can set various levels of overclock and quickly switch between those and an undervolted profile, based on the task at hand. Don't be tempted to tie a profile to a process that always runs, such as explorer.
If you are having problems getting profiles to automatically load after a restart, then this guide by 'ThatOldGuy' on the NotebookReview forums should help. Problems include the app pairings taking several minutes to register that the target process is now running, or app pairings no longer functioning Sager NP8275 Intel Extreme Tuning a system restart.
This will have a cumulative effect that leaves a Sager NP8275 Intel Extreme Tuning portion of the power envelope available for sustained performance. Generally, the cache voltage offset will normally be stable at the same level as the CPU core, while Intel HD Graphics normally hit their limit at a lower offset. Some manufacturers will modify the TDP allowance Sager NP8275 Intel Extreme Tuning be higher performance or lower quietness than the stock value prior to the laptop leaving the factory.
However, most will lock this value to stop consumers adjusting these and potentially creating longevity issues that result in higher warranty claims.
You risk damaging your computer over time if you exceed the thermal capacity of your cooling solution. Performance can be reduced if this action results in more frequent thermal throttling.
Showing TDP modification options. Turbo boost short power max 1 is for burst operation, while turbo boost power max 2 is for sustained turbo operation Conclusion When it comes to adjusting hardware settings, you start going down one path and then it branches out into multiple use cases and scenarios.
Our short guide was quickly growing into something more substantial than our intended scope, and we had to be briefer in areas outside of our core intention of undervolting the CPU.
