    Anyone know how to get XTU to allow undervolting. Lost this ability after updating my AW14R3 to Bios 1.5.0 (From Bios 1.0.8). All I see for "Core Voltage" is Default (0.5V) or higher (up to 2V) but don't have the ability to lower the voltage (Used to set it 0.13 V lower). If not this any alternative ways to undervolt?

    Also, does anyone know what is the "Cash Voltage Offset" and what does changing this do?

    I have used it. But even ThrottleStop seems to have the undervolt lock. Seems to be a Bios thing and not related to XTU.

    Edit: Never mind. They changed the order which screwed up my display. Figured it out
