R9 290(X) Voltage locked?

So if I'm understanding correctly it's not possible to adjust the voltage in software like MSI AB?

There is a Asus BIOS that I can flash to card, then the voltage can be changed in software like MSI AB?

The Asus BIOS works on all reference 290 & 290x?

It's not locked, it's just that they use a new voltage controller that almost no software can work with yet. A new Afterburner beta should be out in a few days that will work with reference designs.

Sapphire 290X should have voltage control when the new TRIXX software is adjusted.
