NVIDIA Maxwell VBIOS mods - 900m series overclocking versions

Recommended Posts

Hey guys! I have an Alienware 17r3 with the GTX 980m 8gb flavor, I have been attempting to flash my vbios with the .rom file provided here in the download section "rev.0". I made it through to the very end when I was supposed to flash the custom vbios and all I get is [ I/O ERROR: Cannot open file: BIOS.rom ] The only thing I think I might be missing is if I need to make the .Rom file into an Iso or not? I've read multiple different guides on here some from 2009 though and now I'm a little confused the first guide I read didn't use any kind of bootable drive it was all through cmd prompt, but then I see a couple others talking about converting it to an iso and putting it on a bootable thumb drive and so now I'm just lost.

I would very much appreciate anyone's wisdom on here since I'm pretty sure I'm destroying the environment with how many files ive downloaded and worked on trying to get this worked around. 

EXTRA INFO: I am also using the (m)nvflash utility provided in the same thread as the vbios file, it is running as administrator. new rom I'm trying to flash is named BIOS.rom

SPECS: AW17r3 / i7-6700HQ / 980m 8gb / 16gb ram / 1920x1080 / 1tb 7.2k HDD and (2) 256gb nvme ssd. System Bios: 1.4.4

Alright. This is what finally worked for me, after hours of trial and error and piecing together additional steps from others posts:

 

(I have a Clevo P150SM-A /w a GTX 970M in it)

 

Before initiating this Flash process, go to your device manager > expand your display adapters > disable GTX980M. Now do the following -

 

1. Download the newest version of nvflash, instead.

2. Create a new folder in your C:\ drive and simply name it "nvflash"

3. Extract your nvflash download into said file.

4. Also move your BIOS.rom file into the C:\nvflash folder.

5. Open CMD as administrator and type the following, in order:

 

cd C:\nvflash

nvflash64 --protectoff

nvflash64 -6 BIOS.rom

 

After that last command prompt, you should get a message about the the subsystem ID's not matching.

Then you will be prompted to press "y" to confirm an override.

The final prompt will say something about the update being aborted/failing/etc.

Don't stress, it worked.

 

Go back into your device manager and enable GTX980M and reboot.

 

You'll be able to easily verify the success with Nvidia Inspector. Just start it up and open the Overclocking window. Your Voltage should now be unlocked.

 

Now OC to your hearts content.

 

So, it didn't work as well as I had thought. However, I did finally get it to work. So here's some new steps:

 

1. Go to device manager > display adapters > disable GTX980M

2. Download Mnvflash (which you have)

3. Create a new folder in your C:\ and label it as "mnvflash"

4. Extract all the contents of the mnvflash download into it

5. Drag your BIOS.rom file into the same folder

6. Open CMD as administrator

7. Now the type the following commands in order:

- cd C:\mnvflash

- nvflash -b filename.rom (replace 'filename' with your stock vBios. this one is optional. just more of a safety measure.)

- nvflash -6 BIOS.rom

 

This time, you should hear a beep while CMD runs.

 

You'll be prompted to hit 'y', twice.

 

Hopefully, everything works and you can go re-enable your display adapter and reboot.

 

If you don't already have it, download Nvidia Inspector upon restarting. Once you open the Overclocking menu that comes along with it, all the options should be usable.

Thanks for the help unfortunately it hasnt worked. I think the problem now is that I can't disable the 980m because as soon as I disable it nvflash wont recognize it in the system. If I disable it, then reboot with it disabled it'll show in the system like it should, but then im still getting the same errors. I even took maxwell tweaker to slightly alter MY stock bios thinking that would take out the wrong id problems, but that still has the same errors.

Update: I was finally able to flash the vbios by using -i o -6 commands and everything seemed to go well, even the prompt said it was successful.. Then I went to enable the gpu in device manager and the whole pc froze. I did a hard restart and now in device manager it says that Windows has disabled 980m because of problems. I tried reflashing but of course its being a b*tch like it was before and not letting me.

Hello @Klem, i'm new you in this forum and was looking at this topic for an hour and i asked myself if you could modified a Acer E5 575g 578n , 950m 2gb no G-sync bios to unlock + 135Mz overclocking limit ? 

 

My laptop running at 62 degrees max ingame and askep myself if i could push the cores beyond the nvidia limit 

 

Sorry for my grammar , english isn't my native language :)

 

Thanks you and what an amazing job you're doing here 

 

NB : if you could send a link about how to flash a vbios i'll be happy because i want to do theses things right and not damage my computer :)

Hi
Your bios is write protected, therefore any modified bios can be flashed by using hardware SPI programmer only.

Hi @Klem

 

I have been digging up the internet to try find a modded vbios for my asus 970m but I have had no luck at all.

I am trying to use core clock above 135+ limit and looking for power adjustment and prevent thermal throttling option in my OC widget.

Are you able to help me with this?

 

Here is the current vbios I'm using

For flash any modified vbios, you should to use special version of nvflash (i sent it to you with vbios), also to flash any GT9XXM (Maxwell core), you should to use command :

nvflash  -6   vbiosname.rom

In your case, use command :  nvflash  -6  970MOD.rom

So far I have the lowest Firestrike score for a 980m I've ever seen at 6807 points. I get power throttling like crazy. I hope the new vbios helps when I can finally download it.

      Hello, I'm on an alienware m17 r4 and am trying mod my vbios for a 970m 3GB msi. I've managed to get the max boost with an increase in voltage, however I believe my voltage settings maybe unstable. When attempting to load programs capable of high gpu usage capabilities, the gpu begins to become pretty unstable. would anyone be able to provide assistance? I have both my edited and original roms as well.

      Flashing Overview:
       
      - Go to the device manager -> 'Display Adapters' -> chooser your GPU, right click on it and choose disable
       
      - Flash the VBIOS with mnvflash, a modified version of nvflash (see attachments). Below are detailed instructions for nvflash in case you aren't familiar with it.
      - After the flashing is done: Enable the GPU once again in the device manager.
      - Reboot
       
      Detailed Instructions:
       
      As soon as you see the command line you're ready to go, write
      dir and hit enter to display all the files on the USB drive.
       
      Display all Nvidia adapters in the system:
      nvflash -a  
      or alternatively the longer version of the command:
      nvflash --list This command will return you a list with all Nvidia adapters present in your system.
       
      Here's an example output of this command run on my M15x with a 680m in it:
      NVIDIA Firmware Update Utility (Version 5.117) NVIDIA display adapters present in system: <0> N13E-GTX (10DE,11A0,1028,02A2) H:--:NRM B:02,PCI,D:00,F:00 The number in the <> brackets is the index of the corresponding device. SLI users will have more than one entry and flash each card separately.
       
      Backup your current VBIOS:
      Never forget to keep a backup of your original VBIOS before you flash anything non-stock. Use this command to save a copy of the firmware to your USB drive:
      nvflash -b filename.rom or with
      nvflash --save filename.rom  
      Flash the VBIOS to your card(s):
      For a single card it's really straight forward, you don't need to worry about the adapter indices. Just use this command:
      nvflash -6 vbiosname.rom -6 will allow you to override mismatches of the PCI subsystem ID. In case of a mismatch you'll need to confirm the flash with 'y'. NOTE: Users with a non-US keyboard might need to press 'z' or similar, because the 'y' isn't at the same location for all keyboard layouts.
       
      SLI users will need to flash each card separately. The concept stays the same, but you will need to use the corresponding adapter index to flash a card. How to figure out the adapter nr. is described above.
      Flashing goes like this:
      nvflash -i[index] -6 vbios.rom [index] represents a number, namely the index you found with the 'nvflash -a' command. So a command example to flash a card which has index 0 is: 'nvflash -i0 -6 vbios.rom'

      In case you want to buy me a beer
       
      Thanks and cheers!

      The new leak of NVFlash version 5.513.0 with their new RTX GPU (Turing) support is now available in our download section. This includes support for NVIDIA's new RTX 2080 Ti, 2080 and 2070 desktop GPUs. As always, use caution when reading/writing vbios files as you can potentially brick your card and void your warranty.
