Simple Tutorial-ish for Kepler (and probably Maxwell II) Bios Tweaker

[Mnky313]

I HAVE ONLY TESTED THIS ON MY K3000M, YOUR MILEAGE MAY VARY AND I AM NOT RESPONSIBLE FOR BRICKED GPUS! (though usually these are fixable)

THIS IS A BACKSTORY STYLE THING JUST SAYING HOW I DISCOVERED THESE VALUES, SCROLL DOWN FOR THE TUTORIAL
So I was searching around for a simple tutorial on how to use Kepler BIOS tweaker to modify my Quadro's vBIOS and couldn't find anything, I tried changing default clocks, 3D clocks, turbo clocks, turbo tables, but nothing seemed to work so i found a modified vBIOS for a k5000m and opened both a stock k5000m image and the OCed one and compared which values were changed from stock.  I noticed that certain things I hadn't thought of were changed.  This worked fine on my K3000M but I have not guarantee if it works for others though I assume it should work for Kepler and because the values are present on Maxwell as well it might work.
These screenshots show the original vBIOS (left) and modded one (right) for the k5000m.  I noticed that instead of adjusting TDP Base Clock (which is what seemingly every youtube tutorial says to do) he enabled the 3D base clock and turbo clock by changing them to entry 2 and 3, then modifying the values.  This still didn't work for me so I drove deeper and noticed that the GPC and XBAR values were set differently between the cards so I set these to the overclocked speed and it worked!

Tutorial:

Step 1 Download the required software: 
You need a copy of GPU-Z, maxwell or Kepler bios tweaker (depending on if your card is 600-700 series (Kepler) or 800-900 series (Maxwell)) and nvflash
GPU-Z: https://www.techpowerup.com/download/techpowerup-gpu-z/
Kepler BIOS Tweaker: https://www.techpowerup.com/download/kepler-bios-tweaker/ (600-700 series cards)
Maxwell II BIOS Tweaker: https://www.techpowerup.com/download/maxwell-ii-bios-tweaker/ (900 series cards and maybe 800 series? idk I can't seem to find a Maxwell I BIOS tweaker)
NVflash: https://www.techpowerup.com/download/nvidia-nvflash/
Step 2 Export your card's current BIOS: 
Open GPU-Z, you should see a little arrow coming of of a rectangle next to the BIOS Version box.  Click it, it should prompt you to give it a name, Your screen might go black for a second THIS IS FINE! it needs to restart the GPU in order to save the image.

Step 3 modifying the image:
GPU-Z should have given you a .rom file. Open Kepler/Maxwell II BIOS tweaker, select 'open BIOS' at the bottom left and open the .rom file.  You should be on the 'common' tab, on the left where is says 'Boost Clock' set that to your desired clock speed (KEEP IN MIND! you don't want to set this too high right away, you can still use MSI afterburner to add 135Mhz ON TOP OF the clocks you set!). IF the Boost Clock option is grayed out, set 3D Base Entry to 'Entry #1' and Boost Entry to 'Entry #2', this should enable the boost clock option. You can also modify the memory clock here but it's not recommend because MSI afterburner can also do this and it's very rare to see a GPU that can overclock it's memory past +1000Mhz

Next go to the 'Boost Table' tab, at the bottom there is a slider, slide it to the same value you set the boost clock at on the common tab.

  Then go to the 'Boost States' tab, under the second 'P00 - Profile' block (if you only have 1 idk, it probably would work setting the 1st one, but I haven't tried it) in the second column there are 2 values 'GPC' and 'XBAR', set BOTH of these to the same value as the 'boost clock' and 'boost table' slider.

Hit 'Save BIOS As' (I recommend saving as a separate file just in case you need to flash the original vBIOS later on)
Step 4 Flashing the modified BIOS:

Open the zip of NVflash you downloaded and extract it to a directory (I recommend something simple like C:\vBIOSmods\ etc.)
Copy your modified .rom file that you got from the BIOS tweaker to the same folder as NVflash.
open device manage, go to display adapters and disable your GPU (the screen will go black for a second and if you have multiple monitors they might not all come back on, don't worry this is only temporary while the GPU is disabled.)
open an Administrator Command Prompt and CD to the folder with NVflash and the rom file
The commands are slightly different depending on if you are on 32 bit or 64 bit windows and if you have more than 1 Nvidia GPU in the system.  replace ROM FILE with the name of the modified .rom file:
if you are on 32 bit windows with a single Nvidia GPU type: NVflash -6 "ROM FILE"
if you are on 64 bit windows with a single Nvidia GPU type: NVflash64 -6 "ROM FILE"

if you are on 32 bit windows with a multiple Nvidia GPU type: NVflash --index-0 -6 "ROM FILE"
if you are on 64 bit windows with a multiple Nvidia GPU type: NVflash64 --index-0 -6 "ROM FILE"
MAKE SURE IT DISPLAYS THE CORRECT GPU ON THIS SCREEN:

IF IT DOES NOT, change '--index-0' to '--index-1' and keep going until it displays the correct GPU!

Once you see matching values on that screen, press y to begin the flash.
DO NOT TURN OFF YOUR COMPUTER WHILE IT IS FLASHING!
If there is an error during the flash and you see ANYTHING other than 'Flash Successful!' Keep retrying to flash, DO NOT REBOOT YOUR COMPUTER, IF YOU CANNOT GET IT TO FLASH THE MODIFIED IMAGE ALWAYS FLASH THE STOCK IMAGE BEFORE REBOOTING!

After this you're done! once it says 'Flash Successful!' you can go into device manager and re-enable your GPU and reboot your machine. After that your GPU should be running at the clock speed you set.

If you have any questions, suggestions, or see something I did wrong post a comment!

hi there my laptop have same gpu but look at this it stuck on 654 MHz even i tried your method......

I noticed it reports the boost clock correctly, do you have another piece of software open (ike MSI afterburner/EVGA Precision X)?, the card's BIOS is reporting the defualt boost clock as 1006Mhz, which means the BIOS should have applied correctly.

thx for reply. but i installed old driver 416.78 beta and now boosts are working.

[Dahaka7172]

hey boosts are not working with new drivers 425.31. seems like drivers changes?

hello i have the same issue i have the k5000m i have flashed the bios and it dont boost just stuck on 601 but the default clock is right 1020? also i cant use driver 425.31 no boost?

After flashing bios, I noticed sometimes you cannot enable the gpu before restarting for whatever reason. Whether manually, or letting nvflash do it automatically. So you maybe be able to run the newer drivers. Also, sometimes it has a hard time noticing the cats at start up and just re-running the install of the same driver will find the card. Oh, sometimes in driver settings you have to disable forced p2

Left some info out.

Is there any way to make the Max Table Clock an exact number? If I slide the bar it never comes to what I want.. I get annoying extra 1-3 more than I want or half values.

idk, but it seems boost clock is the same as max table clock, if you manually change the boost clock does it change max table clock?

Not exactly, if I remember correctly you have just make sure the slider is at the number you set. But remember with afterburner you should be able to set it much higher. I downloaded an unlocked bios too. Like a $7 one time charge lol. Then you can just use afterburner to slide slowly till your stress test faults and dial it back about 15+. If your gpu starts getting hot replace the thermals. 

 

If you want cooler Temps liquid metals are up to -15°C. Read up on it though.

try that nvflash.

even after using that version it did not work

i modified my bios in maxwell bios tweaker and when i try to flash it in gtx 750 ti in cmd it gives me error 7 and 8. i tried to update in different ways, both on old versions of nvflash and on new ones, but nothing worked

I had the same error codes as you whilst trying to flash a Quadro K2200. This version of NVflash I found on overclock.net finally worked: http://www.overclock.net/attachments/41789
