How to correctly undervoltage the laptop version of Nvidia GTX 1070
Here you are: [video link]
You don't have to modify the system files in MSI Afterburner. The video is from over a year ago and was made for an older version of the software. The newest release allows adjusting the voltage curve by default.
A few important notes before I explain the process:
1. Undervolting isn't a simple click-and-go task; it demands several hours of stress testing, since you need to evaluate multiple voltage/clock settings on a graph.
2. On its own, Pascal already provides excellent performance efficiency, so you won’t see a significant increase in FPS or a major drop in power usage.
There are two approaches: one is straightforward and the other more complex.
The straightforward method involves manually instructing the GPU which clocks correspond to each voltage level. This can be done by installing an overclocking tool, such as MSI Afterburner, then navigating to the voltage graph (ctrl + k) and experimenting with each setting to find the most stable performance at the lowest voltage. I suggest reviewing the clock activity at normal settings during a stress test first to understand your GPU’s behavior.
This approach is quite challenging because it requires a lot of time—essentially underclocking 10 voltage points, with each needing individual testing.
Alternatively, you can opt for the easier route: use an overclocking utility and lower the power limit to around 70%. Adjust the setting as much as needed to achieve the desired undervolt effect.

Thank you! I’m sorry, but do you have a video that specifically demonstrates undervolting for the GTX 1070? If so, please share the link.
Thanks in advance!
Yes, Unigine Valley is a great choice.
