Laptop i7-6700HQ GTX 1070 Power Throttle Issue

[kdgbduyu28]

Hello Everyone,

I am seeking an assistance on what should I do / what troubleshooting should I do in regards to my issue.

When gaming, on cold start and launching a game, Board Power Draw / GPU Power is working fine 90W-120W / GPU Voltage 0.9V-1V

But after few seconds (when GPU reaches 65c or experienced too much stress (too much load?)). The issue now starts...

GPU Power is now capped on ONLY up to 50-52 Watts / GPU Voltage is also capped to only 0.8V

I have tried reinstalling driver (clean reinstall using DDU)
Overclocking memory and GPU Clock speed (GPU Clock/memory speed overclock are applied but GPU Voltage/GPU Power are still capped)
Undervolting GPU (Same result) (I have tried ASUS GPU Tweak II, MSI Afterburner, ROG Gaming Center)
Max Fan speeds
NVCP Power management mode is set to Prefer Maximum performance
Link State Power Management is already set to Off

My CPU is already undervolted at -165mV (Temp reading never reaches beyond 80C)

The temperature reading of CPU is between 65-70 degrees and GPU is between 63-68 degrees while I am experiencing this power throttling.
Closing the game/benchmark and re-opening will not restart this capping, it will be like a permanent cap until a restart / turn off the laptop again.

I have tried to lock voltage/frequency using Afterburner but it caps at the capped voltage 0.8V, it won't go beyond that (i.e locking voltage 0.9-1V)
The laptop has been recently cleaned (reapplied thermal paste)

Temperature Limit:
91c Max 54c Minimum

ASUS ROG G752VS
NVIDIA GeForce GTX 1070 8 GB GDDR5
Intel Core i7 6th Gen 6700HQ (2.60 GHz)
16 GB Memory Single channle DDR4
500gb Kingston NVME SSD M.2

Most likely hardcoded limits in the laptop's BIOS to cater for undersized power delivery circuitry...

Hi Kilrah, do you think flashing a modified vBIOS using Mobile Pascal TDP Tweaker may fix this issue?

[Kilrah]

Never used it so no idea. But it might not be in the vBIOS, just in the system one and it telling the card to throttle down at runtime.

If you managed to bypass that and the limit is indeed there for VRM reasons you might fry your board too...
