Windows 10: I tried undervolting my GPU and now my pc doesnt work after resetting the settings of it.

My settings i undervolted to were2550 mhz / 1.000 vmy defaults are 2550 mhz / 1.050 vand when uninstalling msi afterburner to reset the settings, i reset back to the defaults and now nothing wants to load up, or loads up for one second and crashes immediately. Can anybody offer any help?

:)

 

Struggling with underclocking/undervolting GPU to decrease temperature/load

I am trying to limit GPU for an app (that always runs on 100% usage) because it runs too long and too hot for my ease-of-mind.

I thought undervolting or underclocking (with MSI afterburner) would help reduce the allowed load and temperatures. It's not working like I expected (this is also my first time doing this).

My expectation:

• If I undervolted the GPU, it could use a lower voltage when running
  the application (for example, 1700MHz and 750mV when undervolted,
  compared to 1700MHz and 850mV at stock).
  

In reality:

• When I tried to undervolt by adjusting the curve so
  that the frequencies at lower voltages are higher, the program just
  uses a same/similar voltage, and temperature remains around the same.
  And when I tried to underclock by applying a negative offset to the
  clock speed (which shifted the whole curve down), the program just
  starts using a higher voltage, and temperatures remain around the
  same.
  

Picture of curve and load at stock settings. Usage is 100%

Curve for underclocking

Curve for undervolting (???)

Undervolting, second version. I assume the fact that the operating point isn't on the curve anymore means I've undervolted it too much here.

Am I misunderstanding the point of underclocking and undervolting, or am I doing it wrong? Or is there another way to achieve my goal?

Sorry for the dumb question. I tried to look into it on my own but I'm struggling!

I'm using an Inspiron 7577 laptop, with GTX 1060 Max-Q and Windows 10. I think the power limit, temperature limit, and fan speed settings are locked for this model. Haven't been able to find anyway to unlock them. I don't want to open up my machine to apply thermal paste, and I'm already using a cooling pad.

 

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

GPU-Z 0.7.8 / 0.7.9 / 0.8.0 Bios reading not possible GTX670-solved with gpu-z 0.8.1

@Maban - does GPU-Z fail the same way for you the way it does for me? I.e. total system freeze/lockup, requiring a hard reset?

@W1zzard - I will try the suggested steps later today, as I am not near that PC at the moment.
