Hello =p,

I've bought a Dell G3-3590-A30P and I'm suffering from thermal throttle (as everyone else, it seems). I tried to undervolt my processor using ThrottleStop and Intel XTU, but none of them worked.

ThrottleStop let me change the values, but the offset shown in the table doesn't change, alongside the temperature hitting 100°C (212°F). When trying to use XTU, the voltage offset is greyed out:

Laptop Specs:

CPU: Core i7-9750H
RAM: 8GB DDR4 2666 MHz
Motherboard: Dell 01RGT1 (laptop)
GPU (onboard): Intel(R) UHD Graphics 630
Driver: 25.20.100.6617
GPU (dedicated): GTX 1660 ti Max-Q
Driver: 26.21.14.4219
Laptop Model: Dell G3-3590-A30P
System BIOS: 1.9.2
OS Build/Version (dual boot): Windows 10 Home Single Language Version 10.0.18363 + Ubuntu 18.04.4 LTS (I hardly ever use it though)

Any ideas of what I should do?

BIOS updates are being released, likely by all manufacturers, that will block under volting. Do a Google search for Plundervolt if you want to find out more about this issue. Here is the reason why Intel has decided to do this.


This fix has also disabled the adjustable Turbo Ratio Limits. You used to be able to lower those to control heat but not any more.

If you can go back to a previous BIOS version, you might be able to get under volting and adjustable turbo ratios back.

There are going to be a lot of unhappy laptop owners in the near future.

Thanks, didn't know about it. I think I will just replace the thermal paste

I don't understand why they don't just add an auto-tuner? Click a button and let it find the limits, then they note that level and enforce staying comfortably back from it. You could probably still let most people shave off 40-80mv safely.

As is, factory tuning is now super important. Dell usually has way too many volts in their slim and light models, so they're going to be more overheat-prone going forward...

but why are desktop processors also effected but are still able to undervolt + change multis or is my thinking wrong?

@basco - Desktop computers allow voltage control in the BIOS. Most laptops do not have this option. Laptops only have voltage control by using software like Intel XTU or ThrottleStop.

It is software voltage control that is coming to an end. Either a BIOS update or a Windows Update only needs to set a single bit within the CPU to block voltage control. HP and Dell have already started releasing BIOS updates with this fix.

Thank you very much Mr. unclewebb for explaining this to me!

and a big thanks for your time + effort on throttlestop !

if ya need new hardware for testing shoot me a pm- i mean it
