GTX 680 Lightning MSI Afterburner Volt Bypass Guide

Posted February 21, 201312 yr

Today I will share how to bypass the +93mv limt, you all have on your MSI GTX 680 Lightning cards.

Your Cards need to have the: 80.04.09.00.F8 (unlocked LN2) Bios!

Download here: https://docs.google.com/file/d/0ByaqIKti5kitbkxERjVhYVlqbzQ/edit

How to use NVflash:

1: Extract the nvflash files to C:\

2: Save the BIOS file to C:\

3: Open elevated cmd window (hit start button, type "cmd", right click cmd icon, run as administrator)

4: Change directory to C:\ (type " cd C:\ " )

5: OPTIONAL: type " nvflash --protectoff " then hit enter (turns off any error msg that may result from software write protection)

6: BACKUP ORIGINAL BIOS: Type " nvflash -b backup.rom " and a copy of your bios will be saved to the nvflash directory

7: Type " nvflash -4 -5 -6 Yourbios.rom "

8: Wait for it to finish

9: Reboot

10: OPTIONAL: reinstall drivers

--------------------------------------------------------------------------

When you are done with that, we can go to the next step. "Real Overclocking"

You will need 2 programs to do this:

1: MSI Afterburner 2.2.3

2: Artmoney

Make sure youre running both AB and AM "As Administrator"!

1: Set AB vcore to +93, hit apply, make sure its still at +93

2: Go to AM, search for integer with value 93; it should give you like several thousand results.

3: Go back to AB, change vcore to like +70, hit apply, then see what vcore it changes it to (+68 i think)

4: Go back to AM, filter your previous search. Hit filter, then enter in value 68 (or whatever value is currently displayed in vcore of AB. Hit enter.

5: Add The one with the adresse "00449000" - That control your offset!

6: Then you can enter in all the info in the 'edit address' window. I entered in a value of 180 (which will give me an offset of +143 in AB).

7: Set your clocks in AB, and you are ready to GO!

OSB: Remember to Check the "Freeze" box.

Everyone needs to be careful using this method to control their voltages. it is a memory hack... which is a hack! always keep in mind the risk of your actions!
