Any fix still throttling. But it's not thermal throttling it's power limit throttling ... Why.....

I don't have any problem with 1607 version of Windows 10, but I think it's not a real solution, to revert back to an older OS. or disable turbo boost...

1607 will not fix this, it will only take longer than before to occur, but it will. Only Dell can fix this with a bios update. But they are too lazy for doing it.

Dell needs to disable the throttling, what's wrong with them? Are they *** on customers?

A similar issue is well known on XPS 9550/9560.

Power limit throttling after some minutes is carried out by Intel DPTF, because the voltage regulators

(VRM) area overheats. Mind the overheating is real, indicated by other sensors, although the CPU and the GPU may not be excessively hot. By killing DPTF one is bridging a thermal fuse.

Look up iunlock's mod for the 9560, perhaps a similar approach may be applicable.

I think, the cause of the problem is the 130W PSU.

i7 7700HQ CPU TDP:: 45W

GTX 1050 Ti TDP: 70W

It is 115W, more with turbo, and i did not count the TDP of the, display, RAM, SSD. HDD. Keyboard backlit, ports, wifi, etc.

I think the original power supply is too small, on high usage it's overheating, and there is not enough energy for the complete system.

I think the solution is a 180 Watt power supply, unfortunately, I don't have one, to test it.

Ok, I have a workaround.

Revert back to Windows 10 1607

Update Intel Dynamic Platform and Thermal Framework to 8.3.10203.4295

Undervolt CPU, Cache, iGPU, System Agent by -100 mV by XTU  or ThrottleStop

I have no Power Limit throttling anymore. I got stable 3,38 GHz

1 hour Mass Effect Andromeda:

I think, the 130W PSU is way to small for this laptop...
