GTX 1060 keeps hitting Power limit under 80C(G3-572).

HK1994

Recently, I have had my machine repasted with Kryonaut, and it really paid off. No more than 80C on The Witcher 3. However, the ***** GTX 1060 keeps hitting the Power limit. I undervolt it at 1885 MHz at 0.975V, but every time the limit kicks in it is downclocked to 1709-1733 MHz. Kind people of the community, please help!

80C for a Pascal card is definitely within throttling territory. You can not expect maximum boost clock at 80C as throttling begins starting around 63C in roughly 13MHz increments off your core clock.

What's your fan RPM and/or profile?

Share your MSI GPU curve.

I set it at MAX - 6000RPM for both fans.

Share your MSI GPU curve.

It turns out that the memory OC (+400) was unstable, so I was forced to revert to defaults.
At default, the GPU still gets PWR limited at 75-77C(3 mins of standing still):

1. Set to auto and cool boost; more than enough.
2. You really do NOT need any kind of overclocking over 1911 for 1060, and memory speed is best left as it is.

Mine too is a 1060 and with max 1911 at default memory n all those speeds, i get a consistent 60 FPS on witcher 3 (nvidia hairworks off). Also, remove those graphs and displays OSD overlap; these add to consumption. Also, you still haven't shared your GPU graph.

Here's mine for reference: set your min voltage at 925 for win 7, and 950-975 for win 10.

MSI Afterburner "OC Scanner" permanently scarred my default settings.

Just hit the revert button on the main screen of MSI Afterburner.

If you don't want to or unable to revert like @Red-Sand suggested you can create the graph again with max speed at 1900 and max voltage at around 975. Set your memory clock at +0 (no overclocking here). And save it to a profile. After you are happy, make sure to "lock" the profile to disallow at accidental updates.

I couldn't.

MSI ***** up the curve after I use their OC scanner program.

Talking in "****" language won't really help.

Check to see if your profiles are locked. Also, you can try uninstalling all MSI software and NVIDIA drivers and all, and install again. Also, next time, before you try something like, take a system image using free tools like Macrium Reflect. This helps in reverting if needed.
When using MSI, do NOT touch anything other than the voltage/frequency curve, and that too, do NOT OC 1060 beyond 1900.

What you are seeing is perfectly normal for a laptop.
The reason why you see pwr throttling is because the gtx 1060 GPU was designed to use up to 120W power, however to keep temps low Acer lowered the tdp of the gpu to 78W.

tl;dr: the GPU wants to use 110-120W power but the vbios is limiting it to 78W and thus it is power throttling the GPU clock as well.

Unless you know how to edit a Pascal vbios and flash it with an spi programmer there is nothing to be done. With msi curve editing you can make the pwr throttle less frequent but the better and more permanent fix is to edit the vbios.
However your laptop does not have good enough cooling to handle a gtx 1060 with 110W tdp.
My Acer G5 has much better cooling and even that can barely handle it.

Why not oc beyond 1900 and why not oc the memory?

For stable gpu clocks u need temps within 75'C.

I have had th G3-572 with 1060 (6 GB) for about 3 years and GPU never hit thermal throttling. It was almost always on 1911 max speeds as needed (no under volting). Try getting a laptop cooler pad and see if that helps.
Laptop isn't a desktop and it has its limitations, so don't pump up graphics all the way up. Witcher 3 I played at med/high settings, but turned off features like nvidia hair (high performance hit with barely noticeable visuals). And never had any issues.
I used ThrottleStop to set CPU to lazy performance mode; GPU, since 1909, I removed all MSI profiles since Windows 10 1909 didn't like that. And it never hit throttling.
