    You can Google 'undervolt 6700hq' and find guides. However, you should not undervolt without understanding what you are doing. That will only lead to your laptop possibly crashing and a headache.

    It is suggested you use ThrottleStop, here is a video: https://youtu.be/K1srWgovdn8

    It is typically suggested to start with a -0.100 Core Voltage Offset, and if the computer runs ok, you can gradually increase the offset. Once you set the voltage offset, you need to test the laptop by running CPU intensive games or benchmarking programs. If you don't crash, then you are good. If you crash, you need to lower the voltage offset. On my 7700hq, I use a -0.125.

    Throttlestop CAN undervolt your CPU, but different CPUs handle different amount of undervolting. Any game will due, and 3dMark seems to be a free, easy choice.

    Hi,
    Undervolting will not reduce the performance or damage the laptop, use Throttlestop to undervolt, it's a long thread and you can get help from the author as well in here:http://forum.notebookreview.com/threads/the-throttlestop-guide.531329/

    in video the guy has 6700hq same as me so i think -149mv would be fine
  • I would not go that high for the first value. It is likely the guy in the video tested that value on his laptop. I guess you could try it, but you laptop might start crashing.

    Start with -70, then go to -100, -125 then -150. Do not go higher than that. If it crashes after one of those values, start going somewhere in between them. Be sure to test thoroughly afterwards. A BSOD crash won't do any damage, especially since we're talking about an undervolt

    I'm also looking a undervolting the CPU on a G9 793, with either Intel XTU or ThrottleStop, however when looking at the system Intel's XTU service is already running as part of Acer's base install. I'm wondering if this is just an aspect of Acer's default SW image encompassing the 17X with OC  CPU, as there seems no obvious connection to the 7700HQ of the standard Predator 17.

    Has anyone reduced the Core & Cache voltages with XTU and were the values persistent?  My previous MSI notebook I was able to undervolt the CPU by -140mV without effecting stability, however the setting rarely remained persistent with XTU.  Would be looking at starting at -100mV with the Predator 17.

    As the XTU service is running by default it seems expedient to DL the full XTU App, equally I'm not wanting to effect or destabilise the system as gaming is not it's primary role.  ThrottleStop appeals as it simply an App with no impact on the BIOS or services, however running both ThrottleStop & XTU is generally not recommended.  In this case I believe XTU is just reporting default values of the registers being tied to PredatorSense to maintain values for the OC version of CPU.  Right now I'm considering either disabling the XTU service and going with ThrottleStop or delaying ThrottleStop until the XTU service is started.

    I have both Intel XTU and ThrottleStop installed and running. Unless you tell XTU to apply values, it will not touch the undervolt that is applied through ThrottleStop. To tell if the UV applied, download HWiNFO. However, I do not know if it will revert the undervolt if you apply the overclocking feature in Predator Sense.

    The only way would be to undervolt using ThrottleStop, overclocking in Predator Sense, and using HWiNFO to see if the voltage offset is still enforced.

    Following up and after a good deal of testing on my G9 793 i7 7700HQ , GTX 1070, 32Gb  Ram with Prime95:

    CPU stable down to -140mV
    System locks up at -150mV
    No thermal throttling at -128mV over sustained testing all CPU cores at max frequency.

    Opted for Core & Cache voltage offset of -128mV as this offers a good reduction in overall CPU temperature, even under massive sustained synthetic load no thermal throttling.  Set profiles for Performance and Battery with only difference of disabling Turbo Boost on battery to help extend the runtime.

    Intel XTU service I left as the default delayed start, equally with the 7700HQ I strongly suspect disabling the service will have no effect.  As per guides if wanting to auto start ThrottleStop best to delay 20-30 seconds or more.

    CoolBoost on and Frost Core installed
