Undervolting possible with R9 270?

[Shaav]

Hello guys,
is it possible to undervolt the Powercolor Turbo Duo R9 270?
I'm not talking about reducing the Power Target.

I know in afterburner and CCC I get both the power slider as well as option of choosing core voltage, I do have afterburner with the extra EULA added though

UnofficialOverclockingMode = 2
UnofficialOverclockingEULA =I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it.

I tried afterburner yesterday. It did not work. The graphics card did not accept the adjustment.

Pretty sure the only option is to flash the BIOS.
