    Do you know if there’s a power and thermal savings by undervolting the iGPU?
    Personally, I have it at -50mV (iGPU and “Unslice”) but haven’t tried undervolting it further.
    If it somehow lowers CPU temps when playing games with the dGPU, I’ll start testing a deeper undervolt.

    If it's cash, I'd do it. I sold my similarly config'd unit for about that locally to a friend.

    I am not sure you are going to see a big jump going from that model to the 2060 - but if it's worth $854 to you, go for it.

    If you undervolt the iGPU, the difference is huge for maximum performance mode with 100% GPU usage, but for low iGPU usage, the difference is small but still helps.
    But in battery saving mode, the difference is very small.

    I'm using -125mV on mine, actually you can down to -165mV, but further may cause freezing.

    See table below for No undervolt vs voltage offset -125mV on the iGPU:

    iGPU no undervolt vs undervolted.PNG

    Balanced mode is just choosing between 350Mhz and Turbo multiplier based on iGPU usage so it's just jumping between 350Mhz and 1100Mhz.

    About lowering the temperature during a game, probably not so much as the iGPU usage isn't really that much when you are using the dGPU.

    Does anybody know what temperatures the points you can adjust the fan speed % represent?

    Just got a GS65 1070 yesterday. Trouble is it has a strange form of backlight bleed in the upper left corner. The shop have no more stock of the laptop so exchange is not an option. It was bought with a (6.5% discount) gift card, so I'm tied into the store. My only option is a 10% refund (back to the gift card) or spending more on a Razer Blade 1070 or the GS65 2060 edition at around 20% more cost to me. £1495 (GS65 1070) vs £1900 (Blade), £1950 (GS65 2060).

    Not sure what to do yet. Otherwise I love the laptop.

    Scroll down. You’ll see my chart for fan speed and temp points in Silent Option.

    Thanks! :) I'd like to know why MSI don't put in actual temperature values instead of a colour scale lol

    Is there any way to change the colour of the keys that light up when you press the Fn key? Or which light up?
    Also is the keyboard brightness not changing when you press Fn + keyboard brightness modifier keys?

    They didn't do a good job with lighting up the whole keys like the Function keys etc or anything not centred on the LEDs

    Did other GS65 users get a driver causes instability on Windows and that the driver will be disabled message when updating to 1809?

    You can’t change the color of the keys when and is pressed. Also, only keys usable with Fn are lit.
    To change keyboard brightness, it’s Fn+ PGUP/PGDN
    I haven’t seen any driver issues when updating. But I also update drivers anyway when they’re available so maybe I’m dodging bullets.

    Just confirmed with Unwinder about changing the visible voltage range for MSI afterburner's V/F Curve Editor.

    Go to:
    C:\Program Files (x86)\MSI Afterburner

    Look for MSIAfterburner.cfg

    Copy to desktop

    Open the copied MSIAfterburner.cfg

    Look for the section in the picture below, do the change, save it and replace the original MSIAfterburner.cfg with the modified one.
