KGB - Kepler BIOS Editor/Unlocker

[LedHed]

as long as it does the flash with no errors, I would assume so. However why not type out a few more letters just be sure it is going to flash without any issues?

as long as it does the flash with no errors, I would assume so. However why not type out a few more letters just be sure it is going to flash without any issues?

Because I just followed a nvflash guide that says to simply use that command. It flashed successfully so I was assuming that I've done it correctly?

[zalazar]

no matter what i do underclock the speed or mem or power . i even modified the power limit in the kgb.cfg file and set it back to the default 114% , i still get my power goes up to 293% and then crash whatever im on game or benchmark .

im not sure what am i missing , i've done what crazynutz said exactly , unlocking the bios worked with kgb and flashing the bios was a success .

anyone with MSI GTX660Ti PE unlocked bios that worked for them id love to try it out .

Is it better to upgrade to UEFI BIOS?

UPDATED INSTRUCTIONS!!


Flashing bios instructions for any Nvidia Keplar GPU.
YOU DO THIS AT YOUR OWN RISK

I wrote this guide as i couldnt find one anywhere.

First of all, You then need to download these files.

GPU-Z (This is used to grab the original Bios from the Gpu wether multi or single)
http://www.techpowerup.com/downloads/2181/mirrors.php


KGB - Kepler BIOS Editor/Unlocker. (This is used to modify the Bios that you just grabbed from your Gpu using Gpu-z)

KGB supports: GTX690, GTX680, GTX670, GTX660Ti, GTX660OEM and GTX660

New version 0.6.1 (Adjustable Boost control)
https://www.dropbox.com/s/d6dimgnx8cxvlca/kgb_0.6.1.zip

Old version 0.5
https://www.dropbox.com/s/vrunxuq03vj0m5y/kgb_0.5.zip

NVFLASH (This is used to reflash or reinstall the new modified bios)
Make sure this is version 5.127, An older version will not work.
http://www.softpedia.com/progDownloa...oad-16133.html

Steps 1-10.

1.Ok what you need is firstly to make a USB dongle bootable into DOS, To do this read this very easy to follow guide.
http://www.bay-wolf.com/usbmemstick.htm

2.Run GPU-Z and and click on the icon that allows you to grab your bios from the Gpu and save it to your PC.

Each Gpu has 1 bios that belongs to it.

Then also at the bottom of the picture were it is circled in red and labelled 2, If you have more than 1 gpu then you will need to change this to gpu 2,3 or 4.

Then grab bios no 2 from your Gpu and save it to your PC the same way that you did with bios 1

The picture below shows how.....





Also make sure you have a copy of your bios, Put the original(s) in a safe place!!

3.Once you have grabbed your bios put it into C:\Users\ (yourname) and rename it 1.rom

For example the bios from the GTX 690 Gpu 1 is called GK104.rom, I renamed it to 1.rom and the bios from Gpu 2 also named GK104.rom I renamed 2.rom.

The reason why you should put the bios in C:\Users\ (yourname) is because the default path will be set here from KGB.exe so if you are not familiar with the CMD (Commandline) then this is the easiest way of doing it.



5.Take the KGB.exe as well as the KGB.cfg file and also place both of these in C:\Users\ (yourname).
You should now have KGB.exe, KGB.cfg and 1.rom files in C:\Users\ (yourname).

If you have more than 1xGpu then you will have 1.rom and 2.rom respectively in C:\Users\ (yourname).


6.The next thing to do is open up the CMD (Commandline) which im sure you all know how to do.
Once you have the CMD open, Copy and paste in this command.

kgb 1.rom unlock (press enter).

It will now save the new values (i.e. from kgb.cfg) in your bios then print out the new values in the bios.

Do the same again for 2.rom if you have a 2nd card/Dual gpu and have extracted the bios file from the Gpu(s).

Copy and paste in this command into the CMD (Commandline)

kgb 2.rom unlock (press enter).

It will now save the new values (i.e. from kgb.cfg) in your bios then print out the new values in the bios.




7.Now all we need to do is put the new modified 1.rom and possibly 2.rom back onto the gpu, To do this we need to use the USB DOS bootable Dongle that we created in step 1.

Take the nvflash files once you have extracted them and place them onto the USB DOS bootable Dongle, There should be 2 files.

Then place the 1.rom bios also on the USB DOS bootable Dongle.


8.Now the Dongle is ready to be booted from so reboot the PC and go into the bios.
Once you are in the bios make it so the PC boots from the dongle, Once this happens you will then have a flashing cursor telling you that you are in DOS mode.


9.Type in nvflash --list (press enter)
This will then tell you what gpu(s) that you have installed on your motherboard.

10.Type in nvflash -i1 1.rom (press enter)

It will then say flashing Gpu and press Y to confirm, so press Y and the flashing will commence which takes a few seconds.

If you have a second gpu with 2.rom.

Type in nvflash -i2 2.rom (press enter)

It will then say flashing Gpu and press Y to confirm, so press Y and the flashing will commence which takes a few seconds.



Once this is done reboot the PC go into the bios and reset your boot so it boots from your hardrive with the Windows OS on.

Once you get into windows you can see from MSI afterburner or EVGA precision that the power target can be raised from 130 to 150.

When gaming the boost clock should be higher depending on your GPU.

I achieved around an increase of 30 on the core clock on boost alone on both GPU's which is very good.

It will differ for each person and each GPU(s), You can also try other peoples bios as long as iyts the same GPU as your own.

You can also modify the KGB.exe and tweak power settings for even more results but I wouldnt advise this unless you know what you are doing, I would just leave it at stock and use that for the time being.

Common problem that may arrise.
Sometimes when you flash your card(s) you may get this problem were you card is write protected and it wont allow you to flash it.

Picture here of problem...

The Solution
Type in the CMD....Nvflash --protectoff....then try again with the flash. to enable it again do....Nvflash --protecton.

This should enable you to write/flash the bios to the card with no problems.


Additional Information,3rd Feb 2013

v0.6.1 has adjustable Boost clock which are coded into the KGB.

The Boost clock adjust can be found in the .cfg file.

Here is the table with which you should set your boost clock too which are increments of 13mhz.

This is a list of valid frequencies that have been coded in KGB.

771.0
784.0
797.0
810.5
823.5

Set your Boost clock ,flash and then test for stability.

Everything you do is at your own risk

I hope this guide has helped.

Good luck.

Is this guide applicable for UEFI BIOSes?

Thanks!

[kevindd992002]

BUMP to my question please

[theveteran]

I dont know i dont use a UEFI bios if your reffering to the motherboard.
You boot into dos from usb stick so shouldnt matter what motherboard you are using.

[kevindd992002]

No, I'm referring to the UEFI vBIOS meaning the UEFI BIOS of the GPU?

[CrazyNutz]

Got it. So in my case, I can do simply "nvflash mod.rom" and I'm all good, right?

Yes

Is this guide applicable for UEFI BIOSes?

Yes

[kevindd992002]

Yes



Yes

Thanks. What would be the advantage of using any UEFI vBIOS anyway?

[zalazar]

had to modify the kgb.cfg and changed the max boost to 1254.5 cus its never stable at 1305.5 , now my Msi GTX 660ti PE stable with 1255/1800 with 1.212v .
but my problem still the power limit never goes above 100 and most of the time below 100 . between 65-85 also my max temp is 65.
i had my power limit on msi afterburner at 150% . i also tried 140%, 130% and 120% still no changes .
am i doing something wrong ?

What are the current supported options for kgb?

[ruudboek]

I have a MSI GTX 650 TI. Its power consumption is very modest, especially in idle.
Will this bios mod allow it to run with fans turned off when idle?

Why in the world did you quote the damn whole guide?Jeez, some people really love to spamm a beautiful thread...

Imagine if i have quoted him too, would be a guide fest.

I'm sorry, I'm used to using SPOILER tags in quoting long posts but I cannot find it here. I'm not spamming, how could that be spamming for God's sake? You could've just told me to try to avoid quoting long posts and be done with it instead of looking it as spam/troll. Your post doesn't help anything with this thread anyway.

[ovard]

no matter what i do underclock the speed or mem or power . i even modified the power limit in the kgb.cfg file and set it back to the default 114% , i still get my power goes up to 293% and then crash whatever im on game or benchmark .

im not sure what am i missing , i've done what crazynutz said exactly , unlocking the bios worked with kgb and flashing the bios was a success .

anyone with MSI GTX660Ti PE unlocked bios that worked for them id love to try it out .

Powerlimit seems to be broken on these cards :/ See my previous posts, no solution yet it seems. I'd gladly post BIOS etc if it could help. Stuck at 1215 MHZ core and 7000 MHZ mem, powerlimit won't go above 99-102%.

Could you add support for GT640 ?

Please add support for the 650ti 2gb.
