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



Last step uploading the file here, as the picture from the reply tool



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

https://www.overclock.net/t/1521334/official-nvflash-with-certificate-checks-bypassed-for-gtx-950-960-970-980-980ti-titan-x

Here is a list of bad card should be avoided if you Aim for manual OC ( voltage locked to 1.212v!)

For GTX 970/980

Give this try

Zotac980RefOC.zip 137k .zip file

Core clock 1506Mhz 1.3v & Boost off & 3.7ghz memory &300wTDP

i doubt the voltage will pass 1.27v i seem to be the card voltage locked from the VRM

make sure all oc software rest to default before flashing the bios

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 smile.gif

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 frown.gif

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.

The power limit can be changed thru bios?

Canoekovski 09-12-2015 07:02 AM

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

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 )
