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.

      Hi there guys,
       
      I've been looking into getting a new GPU for my laptop (4-lane PCI-e) and enclosure (HP Omen Enclosure) but I cannot decided between the RX 5700 XT and the RTX 2070 (non SUPER).
       
      I did some price to performance calculations (higher is better) with some of the best prices I can currently get in the UK.
       

       
      The RX 5700 XT does perform better and is cheaper than the RTX 2070 (Although the 2070 does come with 2 games) but my main concern is drivers and from what I've heard NVIDIA cards work a lot better with eGPUs than AMD.
       
      If anyone has experience using both red & green or if anyone else has any other input i'd love to hear your experiences and input.
       
      Thanks.

      Hello everyone,
      some time by now I flashed a custom Vbios (thank you Klem) on an Acer Predator 15 G9-591 and I started doing some tests about how far I could go overclocking the gtx 970m without running too hot. With the voltage up to 1150mV and something like 300 additional MHz for the core clock, in the strongest stress condition for both Gpu and Cpu ( i7-6700hq undervolted), the Gpu reaches a max temp of 85C (with some 86 spikes but never more than that).
      Considering that soon I'm going to relid both Cpu and Gpu and clean everything in the internals (laptop is 4 years old) I think I'm going to have some additional heatroom.
      I've already tested some further overclocking and I noticed that even if the temperatures remains under 93C (which is just for testing purposes, but after relidding temps could be nicer) graphical glitches occur and after some time most games crash. But my question is, could it be because of lack of power supply? The laptop charger provides 180W 
      Could there be an increase in overclock margins with a 230W psu or something like that? (Obviously with the same 19.5V output)
      If anybody tried something like that on any laptop model, or knows the matter, I'd like to know
    • By ounces
      After spending significant time and effort to obtain "DC" screen for 8770w (which is essentially a regular IPS panel with fancy board that converts 8bpc LVDS to 10bpc DP), I have finally got and installed one. All works great, except of the one problem...

      It has pretty bad banding / posterization in lower shadows. I have tried profiling it in different modes (full range, sRGB, rec709) - issue persists, and it indeed shows only in the lowest part of the characteristic curve. Mids and highlights are represented fine and show low deviation from reference values.

      GPU is HP K4000M, Nvidia drivers installed "as it is", video-card is identified without a hitch.
      Banding was not present with the original TN panel using the same GPU.
       
      While checking a software side, I have noticed that Win10 has bit depth set to 8-bit...
       

       
      My initial reaction was, - "Easy, let's change it in `nvidia-settings` and we're all set":

      ...but that would be too easy, right? After selecting 10bpc and clicking "Apply" screen went off and back on, only to show that depth stayed at 8bpc. Repeating the above few times yielded exactly the same result and I'm not in a hurry to meet a cliched (and laymen) definition of insanity.
       
      Let's check GPU-Z. So far so good, nothing unusual. Notice the highlighted BIOS version and subvendor string:
       
      Time to delve into other tabs. We are running WDDDM v2.4 which supports GPU dithering, but hey... BIOS version has changed!
       
      Briefly back to `nvidia-settings` to check what is reported by vendor's own utility:

       
      So far, we have two strings for BIOS version:
      80.04.5A.00.02 (let's call it an "A") 80.4.33.0.37 (let's call it a "B")  
      Notice how 2nd one seems to not follow hexademical notation. Lastly, "NVIDIA BIOS" drop-down, reports "A" version:
       
      ...and monitor section which confirms that rig is indeed capable of 10bpc, but currently running at mere 8bpc:

       
      Windows "Adapter settings", reports version "B". It's 2019, diversity is a must.

       
      "NVidia inspector" is of the same opinion:

       
      Now, let's use some seriously legit tools and check-in exported BIOS file in `nvflash`:

       
      Here we have two three interesting findings:
      Reported vendor is Dell, not an HP. See this link for details. BIOS version is back to "A". Have I already mentioned diversity? MXM module uses MX25L2005 flash storage in WSON-8 packaging. If things go real nasty, we should be able to rescue a patient via Pomona clip and external programmer.  
      Loading the same file in "Kepler BIOS tweaker" confirms the facts:

       
      EDID settings, courtesy of NVidia Control Panel. Hex dump can be found at the bottom of this post.
      ...Shall I be worried about "60.02Hz" refresh rate?
       
      To summarize:
      Why two different BIOS versions are reported? Anything to do with UEFI (e.g. HP is sideloading its own during boot)?.. Why two different vendors reported? As far as I remember, this is branded HP GPU. Where to get "clean" BIOS of K4000M for future experiments? Ideally from 8770w equipped with "DreamColor" panel from a factory.

      Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
       
      - MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
      - Razer X Core 
      - Apple TB3 to TB2 Adapter
      -  TB2 Cable (Cable Matters)
      - 23inch AOC External Monitor
       
      I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
      I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
      Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.

      I have been attempting to change my boost clocks values for the longest time, though I've been unsuccessful. I managed to flash my modded BIOS, though no changes seem to have had happened, along with no errors either. Here's all the stuff I used and was able to get. If someone is able to help me with this, it would be greatly appreciated.
