Here it is! SUPER easy guide! Literally 1 step to unlock the full voltage of your ASUS GTX970 Strix! As far as I know this is the only card this works for. There are different codes to enter to unlock your specific card's voltage but this one is specifically for the GTX970 STRIX.


Step 1: Locate your MSI Afterburner folder > Profiles

Step 2: Enter the following code into the CFG file that starts with "VEN_10DE......" there only should be 1 file with this name. If there are multiple its probably from you switching a GPU recently without installing a new version of afterburner. You can also delete this CFG file and then relaunch MSI afterburner to remove the voltage code or to reset all your profile settings.

Code:

[Settings]
VDDC_Generic_Detection = 0
VDDC_CHL8318_Detection = 74h
VDDC_CHL8318_Type = 1

If that doesn't work try this:

Code:

[Settings]
VDDC_CHL8318_Detection = 74h
VDDC_CHL8318_Type = 1

Do this when MSI Afterburner is CLOSED and not open! Once you save the CFG file and open MSI afterburner it should prompt you to reboot, reboot your PC like it asks. This is when you know you have success! Reboot and walla! Full voltage control!!!! MSI Afterburner will grab the additional i2C data and automatically put it in the file as it searches for the voltage controller information. You can verify the trick worked by opening the CFG file again and you should see additional information below in the form of block code.

I HIGHLY recommend staying under +50 on the voltage control. I've seen MSI Afterburner and HWINFO interact in very strange ways and I've seen a 1.400V reading on the GPU which freaked me out... I suggest not running HWInfo if you plan on doing this.

I'm not responsible for broken cards btw. Do this at your own risk!

Another cool feature of this mod is with full voltage control, I have the ability to undervolt my GPU if I'm running stock clocks... I can run stock clocks, +400 on the memory, and then undervolt by -78 which gives me a 1288MHz core with 1.113v core voltage. Pretty cool and thought I'd share that also if you're playing alot less demanding games and don't want to pump a ton of volts through the card. It's surprising how little volts the chip actually needs at the stock clocks...

Sorry for digging up this old thread, but it was surprising to find it, I was stuck to the notion that Asus had disabled overvolting entirely on maxwell strix cards.

Oddly enough overvolting makes the card less stable in my case, while undervolting seems to improve things a little, even though temperature is around 50C under load (plus or minus a couple degrees depending on voltage) as it is liquid cooled. Probably a symptom of the VRM circuit being so flimsy.

Anyway, just wanted to say thank you for sharing.
