How to increase power limit by BIOS crossflash

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.

Good info... for enthusiasts.

I wonder how many threads this will spawn of people borking their BIOS though... :p

New threads of "flashed the wrong BIOS" appear every day even without my help.

At least, now they have a better reason rather than being suspicious of eBay merchants.

hi, I have tried crossflashing my Palit GeForce GTX 1650 Super StormX OC with various different bios brands and keep rebooting into green static. Fortunatley i am able to see through the static and reflash to my backup. I am trying to increase my power limit for a higher clock as i know it can go higher. my load temp doesnt go over 60 with a oc at the moment. Am i missing something please advise

Try this one, if it doesn't work, some cards have a unique design and cannot be crossflashed.

Awsome! Thank you so much for this thread. :respect:
I purchased an MSI GTX 1070 Aero but unfortunately it's min. PL was 95W instead of 75W which my other GTX 1070 have. This is important for mining. For example when mining HNS i get nearly the same Hashrate with PL set to 75W and 95W. So I searched and tried a lot of bioses. Finally I found one working perfektly: Palit GTX 1070 Dual
Flashed with Linux (HiveOS), checked force flash (because of different subsystem ID) and ... boom it works! :peace:

Thank you for this guide, I was able to find correct vbios and successfuly flash it on my OEM HP RTX 2070 SUPER. I successfully flashed GALAX RTX 2070 Super HOF vbios which has 320W power limit!

I run this BIOS currently https://www.techpowerup.com/vgabios/213099/asus-rtx2070super-8192-190623 with AIO on GPU. I would like to increase power limit, is following BIOS safe for me?

Second question is: will I benefit from it? Right now if temps are low, like <48C card boosts itself to 2070 MHz, from 48C it drops to 2055 MHz. The card is OCed in Afterburner +110 Core, +900 Mem, Power limit 120%, Voltage +100%.

Hey friend, I have something to ask you. In what cases does cross-flash brick the GPU? Is this just a luck dependent, like a coin toss?

Hey guys,

O bought a RTX-2080 gaming GV-N208SGAMING-8GC (Subsystem Id:1458 400C) that came with the folowing BIOS with 0% overpower:

www.techpowerup.com/vgabios/219486/219486

I'd like a help for upgrade it to a GV-N208SGAMING OC-8GC (Device Id: 10DE 1E81) that alowd 20% overpower...

I found and tested these 3 BIOS:

www.techpowerup.com/vgabios/213008/gigabyte-rtx2080super-8192-190626

www.techpowerup.com/vgabios/214682/gigabyte-rtx2080super-8192-190708

www.techpowerup.com/vgabios/212921/gigabyte-rtx2080super-8192-190709

The first one (F1)(VBIOS Version: 90.04.7A.00.35) seams to be more agressive, but it is the oldest.

The second one (F2) (VBIOS Version: 90.04.7A.40.22) have a lower GPU clock and one day after we have an update to F3 version...

The last one (F3) (VBIOS Version: 90.04.7A.40.3B) was released 1 day after F2, so I think F2 could have some problem that needed atualization...

Somebody knows the difference between these 3 BIOS (F1,F2,F3)...

All of them run fine in my RTX...

Anyone know what's the better one?
Tx,

Roberto

Benchmark Scores Faster than yours... I'd bet on it. :)
Whichever one works best for you, Roberto.

No need to triple space between lines man.. your post is 3x as long for no reason, ol.

Do you guys think I can flash my MSI GTX 1650 Super Ventus XS OC to something else?
I would really love to increase the power limit because my card barely goes above 60c so I think I can overclock this card a bit more.

A big thank you to you I did not know that it was possible to do like this I have a 1660 super from kfa2 and it is impossible to flash the bios in a traditional way by following the steps to the letter I succeeded in 5 min now I have the 120% power limit unlocked on the other hand I was lucky there were only 1 or 2 compatible bios thank you!

I tried flashing a couple of different bioses onto my galax 1070TI. While powerdraw reported went up, Timespy score and temps went down. My guess is that my card uses different resistance shunts compared to the other cards, might be wrong though. either way you should check that performance actually goes up to make sure gains aren't placebo
