GPU-Z 700W Power Draw Reading and loss of performance after vBios Flash

[Timeles]

So I have a rtx 3050 4gb (laptop) with a 35w tdp and 40w limit and decided to flash it with this tested Lenovo vbios according to this thread. I originally had some issues with nvflash not finding my gpu but I managed to fix that by using the download folder in this video ((1) Increase Your Laptop GPU Wattage With a vBIOS Flash - Asus Zephyrus G15 vBIOS Swap - YouTube). For some reason the nvflash listed here worked for me but the board id mismatch patch or the original didn't.

The issue is that now after flashing I get a error reading of 750W of use on my GPU. According to the same reddit thread ((1) Acer swift X- rtx3050 vbios flash : Acer_Swift_X (reddit.com)), I should disable rtx as my laptop starts up but even after doing that I still get the same power reading. This is also causing my performance to drop quite a bit in gpu heavy tests. Does anyone know something I can do about it?

Here's a quick pic of the gpu power wattage

@W1zzard, flash gpu back to stock and see if that fixes it.

When reverting I get the default power usage and it doesn't seem to have any problems. I just wish I could fix it for the flashed version from what I've heard if the flash is done right gpu-z would measure around 6w idle plugged in instead of 700W.

Well don't crossflash.

You put a bios on intended for a card with different sensors/smd/circuits on your card.

Leave it at stock, there is nothing to gain except a headache.

Yeah after trying some stuff for a few hours I'll just put this off for now I guess. Might come back to it in the future

Don't bother doing a crossflash again, see the next message below mine. Leave the card alone as is, just buy a better card.

To explain what's happening here .. the PCB has circuits to measure the overall power consumption of the board, primarily for the power limiter, to ensure there's not too much power pulled, good info to display in GPU-Z.

Different board designs have different configurations of the measurement circuitry. In order to keep things flexible, this configuration is stored in the BIOS, for the GPU and driver to use. When you switch the BIOS, you're telling the rest of the card to expect the power measurement setup to be configured in a different way than with your original hardware, so the readings end up wrong.

Well that's 2 affirmations of this lol, has nothing to do with gpu-z being buggy.
