Gpu overheating after bios flash

[Ptownboy]

I flashed my MSI Ventus 2X 3070 OC BIOS with the MSI Gaming X Trio BIOS to try and get more power out of my card, since the Ventus BIOS has a power limit of only 100% in MSI Afterburner. However, when I was testing games with the Gaming X BIOS, I noticed my temps were very high in any game I played (78–83°C). I know that because the GPU is drawing more power, the temps will naturally be higher, but even with a -200 MHz undervolt and a very aggressive fan curve, the temps were still high.

So, I reverted back to my original BIOS using the backup I had made before flashing, but the temperature issue still persists. Before I started flashing, my GPU never went above 73°C no matter what game i would play.

Things I’ve tried:

• Using DDU to uninstall drivers
• Flashing a different version of my Ventus BIOS
• Repasting the GPU

Bro, I think you're wrong... someone's already written this many times: don't blindly cross-flash.
I read about an identical problem on a 1650 that was playing with insane voltages and then forced to permanently undervolt to fix this problem.

If you've flashed back the original vbios, which you did, the power consumption and voltages should be the same as before flashing
AFAIK, you can't flash the MCs that control the voltages, only the vbios, that can request more voltage/power from the MCs
Is the ambient temperature the same?

No they are NOT very high.
Relax and enjoy.

Unfortunately, there's a lot of ignorance out there. Board design can change " who powers it and what it powers". Second, there's a whole feedback mechanism for voltages and power consumption; some aren't actively monitored, and the value is calculated..
then there's all the temperature management and not to mention fan control.
etc. etc. etc.... without providing too much information.

So yes!!!! Absolutely yes!!! Cross-flashing an incorrect BIOS can cause permanent damage. 90% of the time it doesn't happen, but it can happen when the design of the cards is completely different.
