NVIDIA Maxwell VBIOS mods - 900m series overclocking versions

Recommended Posts

Hi All,

     Successfully flashed vbios at the beginning of this thread on dual 980Ms in order to fix power throttling issue but now I get a grey or sometimes black screen during game start. Originally had 416.94 drivers. Uninstalled and downgraded to 388.13 with no change. Any Ideas?

 

Specs:

M18X R2

Windows 10 UEFI (temporarily reverted to Legacy for mnvflash)

dual 980M 8GB SLI

dual 330W Power Adapter mod

stock 388.13 drivers

Hi!

In your case vbios it's a part of main system bios, therefore GPU-Z and Nvflash can't save vbios. In this case to modify vbios, you need read main  system bios dump with hardware SPI programmer (like CH341A), then modify this file, and then flash it back with hardware SPI programmer (like CH341A).

 

So the is no (software only) way to mod my VBIOS? :(

Yes, with hardware SPI programmer only.

Hi Klem, I wrote you some time ago, but maybe I didn't explain myself well and now I'm confused about my GTX 960M gpu, so I ask you again, if I can do something to unlock clock frequencies beyond +133mhz or memory that does not exceed +144mhz in overclocking because it crashes immediately.
Thanks I await your response.

Hi!

I already answered you, it's not a bios limitation. It's means that memory type on your Nvidia card can't overclock more than +140 MHz. Because on your card soldered Elpida memory chips. 

Samsung memory chips can overclock much more. Hynix and Micron memory chips also maybe can overclock more than Elpida, but low than Samsung chips.

I understand, thanks, so even unlocking only the system bios it can't do anything for gpu, right?

Good afternoon. I ask for help editing BIOS for NVIDIA Quadro M1000M. After editing, I can not flash it, because NVflash gives an error about an invalid certificate. Any ideas ?

My laptop HP Zbook 15 G2. I know this card is not included with this laptop.

Hi, i have a Clevo P670RG / Sager NP8678 with a GTX 980M 8GB and currently running on discrete mode ( no iGPU enabled ). I'm wondering if the display would stopped working if i disable the GPU in Device Manager ?

Hello i have a 970m clevo 6gb and i tried 970m slv vbios but the board id didnt match and it bricked it and i had to use a hardware flasher to recover it so can someone upload a modded vbios that is compatible with my 970m and unlocks the power and clock limits if someone does i would be grateful

Hi!

You can post here or send me your stock vbios, I can take a look what we can do.

Hi everyone! 

 

I am sharing same problem with locked vBIOS for GTX 970m 6GB. Trying not to do same thing as @hawkjarrett did. At first Ive found 970m slv vbios and I was extremely happy, but now I am little confused and don't want mess with not verified (in terms of match) vBios. @Klem may I ask you to take a look at my vBios, and check If you can somehow unlock it for OC (it is a big waste of potential at the moment)? Laptop is Hyperbook X17-G (polish reseller of Clevo P771ZM-G1), GPU is GTX 970m 6GB. If you can help we can post modified vBios in this thread for other users (or just PM me).

 

Original vBios:

BTW, after looking through different threads I can see that you are truly some sort of Magician :)

I´ve bought from a friend an old Alienware laptop, that he bought in USA when was travelling , the Alienware 18, that came with GTX 765m SLI and i7 4700mq. It is working great, but with the GTX 765m sli... Discovered that the Aw18 could receive upgrade of the gpu to the GTX 9xxm, series with native drivers from Nvidia, without having to moddified the drivers, only needing to update the Laptop Bios. (wich I have done already, to the A12, and then flashed the A12 unlocked too.
I live in Brazil, and here we don´t have access to the MXM gpus. Very rare here.
To play some newer games, decided to find a single GTX 980m mxm, beacuse sli is dead, and in newer games, only one of my 765m works, and it gives me very low fps.
Only place I could find one was in Aliexpress. Bought the Gtx 980m 8gb. Along with the 100w heatsink too.
Received the gpu, Uinstalled my old ones and installed the gtx 980m. I´m in UEFI mode. In, bios, it shows the nvidia card, no problem.
First boot with windows 10, windows install his drivers, one from March, 2018. Asks to reboot, then my problems started...
It gives me pink strippes all over the screen.
Only way to bot in windows 10 normally, its to boot in safe mode, and then, remove any driver with DDU.
2 or 3 times, I could boot normally in windows 10. Updated the drivers for the last ones, december 2020. Gone to Gpuz to make things are ok, runned the pci express bus test. some times it works, some the screen freezed..
Tried a lot of different drivers, 2018, 2019 and 2020 drivers.
Same problem.
One time, I could run Starcraft 2 and Bf4, when the laptop didn't hanged, but now I cant even do that. Made a fresh install of windows 10, but same thing happens...
I have the laptop video settings in SG mode now, but did everything from the fresh install of windows 10 with laptop ins PGE (discrete).
When the laptop worked for some minutes, I could see that in SG mode, the GPU and Memory clock of the 980m were stuck in 405mhz. When changed to PGE in Bios, then the clock raised up. But, now, I can`t make any driver work...

Am I missing something here?
Can anybody give me some advice on that?

About 15 days trying to figure that out....

Maybe different Vbios for it, could resolve this problem..

Hello @Klem I was wondering if you could shed some light over a problem. I have an M18x R2 and installed a 980m - the unlocked vbios version which I had in my GT70. It is the Clevo version- but I had hex-eddited the subsystem id to recognize it as an MSI so that i may install the gpu drivers plug and play.  Installing the drivers via NV clean worked as a charm, it wa srecognized as an MSIcard by gpuz -  it benches good and all in all but i have found a vbios for the sli versions on the dell site, and flashed the one for gpu 1- Master and it changed my subid to a dell one but not one that would allow me to install the drivers without the inf mod. I have tried since more than 15 versions of nvFlash  in Windows - as well as in Linux and I have also reprogrammed the vbios using a chip programmer - desolder - flash-resolder - but still it allocates the same subsystem id -- i do not understand why?

Please tell me, where did you find M5000M vbios? As far as I remember, I did not post such a vbios.

      Hi,
      I have an old Dell Alienware M17R3 (2011 built, “new”A12 Bios). Back in 2014 my GTX580M broke, so I decided to put in a GTX680M, which lasted till recently. Now I’m stuck again with 8 beeps and the LCD not turning on. When I remove the card and switch the laptop on, the LCD at least turns on, so I guess it’s a faulty GTX680M. Now...back then people suggested not to go for a GTX580M due to bad thermal values, but as I’m not really using the Laptop for gaming anymore, wouldn’t a GTX480M possibly be a better alternative that lasts even longer? I heard that GTX700M’s could fit in as well, but people reported non fixable sound issues plus thermal issues. Any ideas?

      Okay here is what's going. I have a alienware m18x r1 running an amd 8970m, I wanted to upgrade it to crossfire but I could see a 8970m was more expensive than a r9 m290x
      So I decided to buy a r9 m290x and see if I could make it work in my alienware and also run crossfire.
      Even though many shops refused to sell me one because the didn't think it would work in an alienware m18x r1 only in the r2.
       
      Here is the whole process.
       
      19/08/17 23:15
      No post bios showing when booting, so impossible to enter bios menu, but can boot into windows 10 with no problems.
       
      19/08/17 23:20
      Because I haven't deleted the old AMD 8970m the r9 m290x shows as a 8970m with no problems.
       
      19/08/17 23:34
      First performance test was a success. The r9 m290x changed p-state normally. The gpu fan start spinning normally. But because of no thermal paste, the test lasted 20 seconds because the temperature raised fast.
       
      20/08/17 00:00
      Created a backup of the vbios version
      015.032.000.004.044450
       
      20/08/17 00:10
      Flashed a new clevo vbios version 015.032.000.003.044465
      Caused the card to be corrupted and resulted the 8 beep code.
       
      20/08/17 00:35
      Finally managed to flash the back and return the graphics card to its original state.

      20/08/17 00:50
      Flashed a new dell vbios version 015.046.000.014.045579
      No change in behavior
       
      20/08/17 01:07
      After trying multiple vbios with no luck I finally found one.
      Dell vbios Version 015.041.000.000.044966
      Brings back the post bios screen and I can now enter the bios menu through the r9 m290x.
      Note: This vbios reduce the cards performance from 900 mhz to 850 mhz
       
      20/08/17 01:21
      After more testing I found one that is working with no limits.
      Clevo vbios version
      015.036.000.005.044618
      Brings back the post bios screen and I can now enter the bios menu through the r9 m290x.
      This will be the vbios I will keep at the moment.

      20/08/17 01:56
      I completely uninstalled the previous driver and installed the newest driver. The graphics card is recognized as a 8970m but works normal.

      21/08/17 20:15
      I have inserted my old 8970m in the secondary slot and will start testing crossfire.
       
      21/08/17 21:45
      I have found out that the fan for the secondary fan did not spin. The is a cable that have felt out. I will fix it now.

      21/08/17 22:00
      In my try to test crossfire compatibility, I installed the newest AMD driver 17.7.2 but as soon it installed the driver for the secondary card it caused black screen. Only booting the computer in safe mode brings the screen back.

      21/08/17 23:02
      After many frustrating hours I finally managed to get crossfire working with the r9 m290x as the primary card and my old 8970m as the secondary.
      I have flashed the same vbios on both cards so the r9 m290x shows up I device manager as a 8970m.
       
      I first installed AMD driver version 16.2.1
       
      Then installed AMD driver version 16.6.1 in order to play battlefield

      21/08/17 23:20
      First test run in battlefield 1

      21/08/17 23:40
      Battlefield 1 is flickering bad, this can maybe be solved with a new patch or driver.
      Other games I have tried is working perfect with crossfire on.


      Now what I would like to try is somehow force the r9 m290x driver to be installed and see if it will make it possible to run the latest AMD driver without getting a blackscreen.
       
      I have tried to edit the .inf file like you would do with nvidia but no luck.
      I have also tried to figure out how to edit the device id in the vbios, but I find it too complex.
