Unwinder says you can put this "/wi6,30,8d,10" into the target of an MSI AB shortcut and get 100mV added onto your core, so i tried it out and it turns out it works. Did some thinking and talking with tsm106 and we realized that you can use this to change voltage at will.

To set +100mV offset:
MSIAfterburner.exe /wi6,30,8d,10

To restore original voltage:
MSIAfterburner.exe /wi6,30,8d,0

10 = 100mV and 0 = 0mV (Back to stock). You can also add more voltage. Like i did, instead of 10 put 20 you'll get 200mV.

Be careful though, AFAIK there's no real limit.

1. Find your MSI AB directory.
2. Make a shortcut of the MSI AB.exe onto your desktop.
3. Right click, properties and paste this at the end of target "/wi6,30,8d,10" Behind MSI AB.exe. This will give you 100mV hence the number 10. (Change the last 2 digits)
4. Run the shortcut after running the shortcut with edited target and you should have an extra 100mV. (This will not launch MSI AB, you'll have to launch MSI AB from the original .exe or shortcut)

To go back to stock just put 00 there instead of 10-15-20-25 etc etc. And keep this in mind guys.

The two digits you add are in hexidecimal and each step adds 6.25mv. For 150mv you need 24 decimal which would be 18 in hex not 15. Putting 15 gives about +131mv

Do NOT come whining at me if you fry your shyt. I have done this personally and ive got no issues YET. And i dont think i will. And increase the last 2 numbers in small increments just to be safe.

/wi6,30,8d,10 = 100mV
/wi6,30,8d,20 = 200mV <--- Wouldnt go past this tbh.
/wi6,30,8d,30 = 300mV
/wi6,30,8d,40 = 400mV
/wi6,30,8d,50 = 500mV



BTW, no need to flash to an ASUS bios . Use your stock uber bios.

Might left out any details or not been clear enough, so just ask me.

Ah okay, excellent! Thanks for pointing that out.

Do you have to keep running the shortcut with the mod every bootup out of curiosity?

EDIT: So I tried out the mod with a 15 setting (+150mV) and got a very strange result. My FPS in valley and heaven dropped drastically from 60-70+ FPS on the first few scenes to barely over 20FPS with the mod enabled. GPU-Z registered the change in voltage, showing VDDC going from 0.961 to 1.086 with the mod enabled (before running benchmarks). After disabling the mod (setting back to 0) and rebooting my machine, my FPS was back to normal. Any thoughts?

Did you increase power limit?

 

[Rangerjr1]

Guys, when overvolting ill get a black screen at times. Any ideas?

 

[Rangerjr1]

yup when overclocking and increasing the voltage a lot of people get blackscreen after a few minutes of playing. happens to me when i use gputweak, havnt tried this new msi method. have you the asus bios? it might cause issues on other brands.

Nope, right now im running stock uber bios. MSI AB doesnt change anything, still black screening

 

[Rangerjr1]

If you guys find a fix or something, please post it somewhere.

 

[Rangerjr1]

Yup power limit in afterburner was +50

As for the blackscreen issue, have you still got the Asus GPU Tweak installed? If so uninstall it reboot, did the trick for me. Havent had any black screens. Also some people are reporting only getting black screen crash with the latest beta drivers, might want to try rolling back to the beta 8 drivers.

Ill try Beta 6 drivers.

 

[Rangerjr1]

Beta 6 drivers arent any better than Beta 9.

 

[Rangerjr1]

Good work on the guide Ranger.

Knowing that you made an awesome guide i am very happy that you complimented my guide! Could be better though, got some grammatical errors and im not very detailed in some areas. Please call me out on it if you see anything unclear.

By any chance havd you tried the original beta 3 drivers yet? Might go back and try these if you havnt

I have not tried this yet.

 

[Rangerjr1]

Re read my last reply to you LtMatt, had some stupid grammar errors that made it very confusing...

 

[Rangerjr1]

Don't worry about it. I find the more people reply and use it you get more feedback and can change things to make it easier for others next time. Good work.

Thank you

 

[Rangerjr1]

Ohhh god i feel soo stupid. Thanks mate for pointing out,sadly tho once i altered the voltage and oc'd i got the black sreen problem.

Yep, try to change your screen refresh rate to 60hz, and dont go over the number 17-19. This is ideal for me.

 

[Rangerjr1]

I dont think 60hz is a solution the the blackscreen im already playing 60hz

Ok, try not to overvolt too much, i get blackscreen when i go over 17-19.

 

[Rangerjr1]

Im at 60hz and only added 10,still blacksreen at the end of the TR bench.Right after the load drops from 100%.but the way its same as yours Ranger,like i unplugged the DVI connector.It has to be driver related tho.

Yep.
