I think this particular 5770 doesnt actually support voltage tuning, but I could be wrong.

most of the HD5770 lines (with the exception of maybe MSI's twin frozer) are Voltage locked with non programmable VRM controllers (it's cheaper that way)

they should be a resistor mod or something to augment voltage?
