Hello

This thread will be for custom bios for all GTX 900 cards ( Maxwell ) Or Kepler card! Upon request !

What we can do here ?

1-Disable the boost ( to avoid throttle at 67c)
2-Increase the TDP limit
3-Increase the voltage
4-OC the memory
5- Custom fan curve
6-highest OC without any OC software!
7- Unlock the hidden voltage slider for Titan-X + 980 Ti Cards!

Update.. full video for how modding Gm200 (980 Ti & Titan-X) bios and flash 2 card in SLI..

How I can get a custom bios ?

1- Extract the stock bios..

here is how to extract and flash the bios ( extract and re-flash only ! ) again this video for how to extract and flash the custom bios!
Or: Gpu-Z can extract the bios as the picture



chose the save place and hit OK!

2- uploading the bios here

The file should be .zip to upload it here or simply use external uploading drive..

right click on the bios rom and hit add to archive. then as the picture

Now you'r ready to GO!

How to flash any bios ?

the video in step 1 or step by step
Quote:
1-copy the bios to Nvflash folder
2- copy Nvflash folder to C driver
3- Disable the card from Device Manager
4-Open CMD as admin
5- type: cd /nvflash
6- nvflash biosname.rom
7- hit enter then Y
8-wait 30sec and Nvflash will ask for a reboot
9- enable the Video card from Device manager
10- Reboot
11- Have a fun!
For SLI user:

you should use special command to tell Nvflash which card to flash.. here is the command
Quote:
nvflash --list
to see all cards you have and what index they've been assigned

nvflash --index=x bios.rom
to flash to a specific card in a multi card system, where x is the index number from the nvflash --list command

nvflash -f bios.rom
to force flashing
Here is a copy from Nv flash + MBT 1.36v

NvflashMBT.zip 1797k .zip file


Here is a modded Nvflash (For 980 TI / Titan X ) cards

Hello!

I have a Inno3D iChill GTX 980 HerculeZ X4 Air Boss Ultra

http://www.techpowerup.com/gpudb/b3100/inno3d-ichill-gtx-980-herculez-x4-air-boss-ultra.html

ASIC Quality 71.4%

This is my stock BIOS

Inno3D.GTX980.4096.141031.zip 136k .zip file


and this is the one I'm using now without problems, identical to ZOSON's BIOS for Reference GTX 980 (GameStable replacement) GM204-REFERENCE-EVGA980SCACX20-AIR-31-83

Inno3D.GTX980.MOD.zip 136k .zip file


I've tried OC at 1530/2000 Mem with 125% Power on GameStable and seems to be stable while benchmarking but it eventually crashes after some time playing Witcher3. OC at 1500/2000 Mem is 100% stable while gaming. Cooler is superb on this card, perfectly able to keep the temps under control at all circumstances. Board is based on reference design.

Do you think it is possible to improve it?

Thank you very much in advance!

Hey Mr-Dark, it's me again

Is it possible to hit 14K on Firestrike with air cooled GTX 970 FTW?

The one you made for me is 1519 core, 7400 memory, 1.243v, 240w TDP and it is around 13.5K. And I can't overclock it, even 1530 is causing artifacts. Could you please tweak it further? I used 1275v of somebody else's and seems like my card can handle 1275 for 7/24 usage? Is it too much? The reason why I don't use it is it has boost enabled

Thanks in advance

edit: I'm planning to do the shunt resistor modding, found on overclockers.guide

Hi Mr-Dark, great service you provide.
What are the chances of bricking a card flashing bios? After the modded bios is installed, can the Gpu still be tweaked with Afterburner or is it locked? What is the max safe voltage? Thanks.

Hello there

Give this try

Inno3DGTX980Dark.zip 138k .zip file


Core clock 1531Mhz & 8Ghz memory & 1.3v (i doubt the card can pull 1.3v ) & 300w TDP & Boost Off

Flash and report back!

Hello there

no chance for flashing wrong bios to the card (Nvflash will refuse to flash ) & if you flash bios with unstable clock will result black screen (just plug in the screen cable to integrated graphic and reflash the stock bios )

you still have full control over the Core/ memory clock after flashing my bios but the voltage will be locked from the bios also the TDP the same no need to adjust them

the max safe voltage for Air cooled card is 1.28v (some card with good cooler can use 1.3v with no problem like the G1 from gigabyte )

Yes

Hello Mr-Dark..

I have this card https://www.techpowerup.com/gpudb/b3135/colorful-igame-gtx-970-top.html

maybe you want to experiment on "non-mainstream" card such as Colorful

Colorful_iGame_GTX970_Top.zip 136k .zip file

so you can help me to achieve good and stable OC biggrin.gif
Hello there

give this try

ColorfulGTX970TopDark.zip 136k .zip file

Thanks.
I can add this OC to the bios for 24/7 so no need to use any oc software anymore or can add some voltage and TDP so you can push more

its up to you tell me what you like to do

Would I benefit much from adding voltage and raising Tdp?

Could you add the overclock to bios and up the voltage and TDP to whatever you think would be suitable? My card has a Twin Frozr V cooler and doesn't usually pass 70c ( I'll say 75c to be safe

) on auto fan profile.
Thanks.

Only way to know how much you will gain trying the bios

MSIGTX970Dark.zip 136k .zip file


Core clock 1531Mhz & 8Ghz memory clock & 1.27v (some people report 1.26v max for gaming card ) & 310W TDP & boost off

make sure all OC software reset before flashing the new bios

Running perfect so far @1.275v and temps are fine, currently 73c in Furmark.
Will test it out gaming all day tomorrow and see how far I can push it

Thanks a million for the help.

Here is a shot of GPU-Z with your bios.
