NVIDIA 'Maxwell' VBIOS mods

 

 

Here you find modified VBIOS versions for the mobile parts of the Nvidia 'Maxwell' series.

The VBIOS versions in this post are tweaked for performance and versatility. You'll get almost complete control over the performance parameters of your GPU.

List of available VBIOS mods:

 

• Nvidia GTX 970m - 'OC edition' rev0 - >> 6 GB Version << - modified by @johnksss & svl7 -> see attachments
• Nvidia GTX 980m - 'OC edition' rev0 - >> 8 GB Version << - modified by @johnksss & svl7 -> see attachments

 

Screenshot demonstrating the capabilities of the 970m versions:

>> Read the instructions carefully before flashing! <<

If anything is unclear after reading or if you have additional remarks, please post in the thread.

 

Flashing:

 

- 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). Here 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

Do NOT use driver 347.09, it's broken and useless and won't allow you to overclock, even with the stock firmware.

Don't distribute the files hosted here outside of Tech|Inferno. Don't modify the files you download here.

As guideline:

With the 970m mod you can expect about 10.1k GPU score in 3dM11 when running the modified vbios at stock, and about 13.5k for the 980m.

Advanced Warfare running stock on our vbios.

Great job, guys) Is it only form MXM versions of the 970M 6Gb an 8Gb?

[svl7 5714]

Right, I'll add 3gb and 4gb versions when I get the chance. Also an Asus version. Should be up during the next couple of days.

Gotcha, tnx! Also, you meant 3dmark13, right?)

[svl7 5714]

No, I mean 3dMark11. There's no 3dMark13 anyways

[musiek64 12]

Can you unlock bios in Asus G751Jy Gtx980m ?

[ssj92 115]

Awesome! I can't wait to try this tonight. Should the nvidia drivers be removed or is it okay to have them installed, just disable the gpu in device manager when flashing?

[whatsupdo7 10]

you are the best! by the way.. are you sure it is 3dmark 11? because i already got the 1.3k graphic score from 3d mark 11 test... not even flashing bios yet.

may be you mean the Fire Strike?

[Red Line 22]

Hehe) That's how some people call Fire Strike - 3dmark13!

I thought you were talking about overclocked results for the GPU, cause i saw Prema 970M run and he hit 10.1k GPU score in Fire strike!

[johnksss 720]

Just disable the gpu or gpus in device manager. Start the flashing process. then re enable gpu or gpus. Then restart machine.

That was just a guideline for people to see whether the card is performing as it should. The vbios is not overclocked by default since every system and card can behave differently.

I've seen people posting benchmarks with a 980m having 10k GPU score in 3dM11 and wondering whether everything's okay - well, in that case it's not. That's why I put those numbers there, for people who aren't that familiar with how it should perform and don't know what they can expect.

With overclocking you can get 16k+ GPU score in 3dM11 with the 980m and 14k+ with the 970m.

Wow it's awesome Thank you for your great job

Just flashed it, will try benching a little later.

I followed the procedure.

and did the following (under command prompt - admin)

-Disabled 970m under device manager

- command prompt with administrative priviledges

- Went to Mnvflash and input the following command:

ex: c:\mnvflash -6 bios.rom

and i get this error

"ERROR: FIrmware image filename must have a valid extension. (.rom .nvr. efr. ef)

I've got the vbios version Clevo 970M vbios version 84.04.22.00.13. used with MSI GT60-16F3

====

Update :

Got to flashed it.. the file name is too long so the solution is just to put the name like this . ex: c:\mnvflash -6 Nvidia~1.rom

then follow the procedure.

Is your cpu over clockable in the bios?

[omega939 30]

Eh guys.. what's the safest setting to oc the core and mem clock and as well as adjusting the power limit for 970m? tnx

[ajimijames 10]

Awesome work guys! Here is my vbios from an Asus G751JT with GTX970M. Maybe it can help with the progress for us Asus user.

For 24/7 i'd recommend any highest overclock you can achieve with no voltage bump. For benching - there're no limits! Just make sure your temps are in safe range, not more than 85C.

[omega939 30]

So far this is the stable bench in 3dmark firestrike

core clock = 175

mem clock = 600

Do you think getting an extreme mobile proc will help increase the benchmark? By how many pts you think? Thanks

[Talon 16]

Thank you to both of you for all of your hard work and dedication to this community. Where is the tip jar?

What exact does the power limit slider effect? I understand the voltage offsets, but not sure exactly what the power limit does and how its effected by the limit I impose. I assume 100% is stock.

The power slider will determine the maximum power that the GPU can draw in Watts. If you overclock then you'll want to increase the power slider beyond 100%, otherwise the GPU will throttle it's clocks when it hits the 100% limit. If I had such a GPU, and my temperatures were good, then I'd just put the power slider to max to avoid any power related throttling.

[omega939 30]

it seems that I've hit the limit for my 970m

175 = Core clock

600 = Mem clock

I wont touch the Power limit yet (default settings) unless you guys know the safe limits to move the slider for this one.
