Is it possible to override the 1.3v Voltage limit in MSI Afterburner?

[QuadDamage]

Right now, I'm running my HD 6870 with 1015mhz on the core and 1172mhz on the memory.

This is done with the Voltage slider maxed out, at 1.3v


Is there anyway to override this? I'd like to try a little more voltage to see where and how far this GPU goes.
