Since BIOS editing isn't possible since Maxwell. The alternative to increase power limit is to cross-flash to another BIOS with higher TDP. This method can also help with other BIOS-controlled features such as: minimum fan speed, fan stop feature, voltages, clock states, and more. However, there some rules that need to be accounted for:
1. Target BIOS must the same output connectors like your card. If you have: 1x DVI-D, 1x HDMI, 3x DisplayPort, the BIOS you're flashing must have the same.
2. Target BIOS must have the same Device ID like your card. This can be bypassed by using SPI flash programmer like FlashcatUSB or CH341A.
3. Target BIOS must support the same memory and timing.
4. It is desirable to have similar clocks but not a must.
5. Target BIOS must the same PCIe power configuration (e.g. single 8-pin, dual 6-pin) like your card. Different configuration may reduce performance and affect stability. That's something you won't see in the TPU database and have to look in the vendor's site.
6. The power target and limit in the BIOS file are more important than the percentage power limit in MSI Afterburner.
How to flash?
Download modded NVIDIA NVFlash and extract it to the some folder. Copy the BIOS file(s) to the same folder.
Run cmd.exe with administrator privileges and navigate to the folder where you put the files:
CD C:\Fullpath\
***If the folder is C:\Users\David\Downloads\New folder use "CD C:\Users\David\Downloads\New folder\"***
Type: "nvflash64_patched_5.590.0 -a" to see which adapter id is the card you want to flash.
And then type:
nvflash64_patched_5.590.0 --index=0 --protectoff
nvflash64_patched_5.590.0 --index=0 -6 filename.rom
***Change 0 to the correct adapter id, and filename.rom to the video BIOS file***
Troubleshooting
Sometimes NvFlash just like to "act up" for no good reason, if this happens, just reboot and try flashing again.
If you accidentally bricked the card, check out this guide to learn how to recover from a bad video BIOS flash.
