Download MSI Lightning Beta 15 SE version. In settings check "unlock voltage control", and "unlock voltage monitoring".
Go to Monitoring settings and in Active Hardware Monitoring Graphs choose Core Clock, GPU Voltage, and GPU Temperature to be in the On-Screen Display (OSD). Start RivaTuner Statistics Server which comes bundled in Afterburner. Select Show On-Screen Display and edit some settings if you want to. These steps were all for being able to monitor critical things while doing benchmarks.
Download VGA Fan Controller by MSI or install it from the CD you got. You need this to change the speed of your middle fan.
Turn up your fans to comfortable levels (I turn my casefans all the way up, the big lightning fans to 75% and the small one to 60%)
Flash Skyn3t's LN2 BIOS to your card. The BIOS can be found on the first post here. There are many tutorials for flashing, but basically just flip the BIOS switch on your card to LN2, start cmd as admin and select your directory for NVFlash (CD C:\Users\username\nvflash directory) and type nvflash biosfilename, and it should start flashing.
Download Rbby258 ABvoltmod Tool for later use.
Download Valley benchmark by Unigine and run it at the highest settings. You should see the Riva statistics in one corner.
Go to Afterburner and select +25 on core and run the benchmark. If it's stable, which it really should be, increase by about 10 on core. I would personally just jump straight to +100 and increase by 15. When you get unstable, add more voltage. Start with +15.
Just change it until it shows a higer value in the statistics when running Valley, it varies if you need +5 to +20 to make the voltage change. Increase voltage until stable and add some more clock until unstable, add some more voltage and repeat.
I run my card at 1300MHz at 1.17v when gaming, but I can go to 1370MHz with 1.32-35v. To achieve higher voltages than the 1.212v you get after flashing Skyn3t's LN2 BIOS, start Rbby258 tool and write a value higher than 100 in the core voltage field, click send, and change memory or fan clock by 1% and click apply in afterburner. The voltage should now have increased to about the number you wrote.
Your card shouldn't get much hotter than 80C, so keep that in mind, and don't increase voltage to over 1.35v.
Do the same with Memory except that you increase the voltage to max first and increase clocks until unstable, then decrease them until fully stable. To see if it's stable you change the Core clock and voltage back to normal and run Valley with only memory changed. You can change the Memory voltage by pressing the little gray arrow beside the Core Voltage adjuster in Afterburner.
When you're comfortable with your memory clock just add it to your stable core overclock and maybe decrease the memory a litt bit because it usually isn't as stable when core is also overclocked.
Oh, and before I finish, I've had some issues with the driver. When it crashes after a too high OC I usually have to log out and in again or restart my computer for Afterburner to work properly again.
Small edit: stable clocks depend a little on the program too. Uae a few different benchmarks like Heaven, 3Dmark and play some games that you like. FarCry 3 is a beast for testing if your clocks are stable.
Play Safe! If you want me to clarify something just tell me!Edited by flotrollet - 11/10/13 at 5:40am
