MSI Afterburner Voltage Curve Editor Tutorial - Undervolt

msi-afterburner-undervolt-how-to.md

Tutorial

• Start at default curve.
• Ctrl-click-drag any point in right-half to bend it until a point intersects with desired mhz/voltage.
• Select point and adjust to perfection using shift-up-down.
• Shift-click-drag empty space and select points (including selected point) on the right. Selected point should be left-most point.
• Shift-Enter twice to flatten all points in selection area. They will flatten to match the selected point.
• Adjust if required.

Controls

• Tab - Next point

• Shift-Tab - Previous point

• Shift-Up/Down - Move point up/down (rounds to nearest 5 when applied)

• Enter - Text enter mode

• Shift-Enter - Switch to mhz mode

• Shift-Enter (x2) - Flatten selected range to selected point

• Shift-click-drag in space - select range

  • Up/down arrow to move all selected. (Selected point must be in range)

• Shift-click-drag point - Move all points up/down

• Ctrl-click-drag point - Rotate curve

  • Dragging point situated in the left/right half of graph decides the pivot point (left-most or right-most point).

• Ctrl-z - Undo

• Ctrl-y - Redo

I wish I knew where the file was as the graph is a huge pita and refuse to accept what I do. I see it in the graph then click the check mark and it always bounces back, or other weirdness.

Yeah on ampere I could do flat line from start to end to keep it pegged at base 3d clocks, on lovelace its forcing the curve on right side, if I lower any of the right dots, they just ping back up. Also shift enter doesnt really do anything.

Yes, exactly. On my old 1060 I never had this issue. I have since noticed it lacks freedom and seems to snap to various points. Not sure if Ada related or afterburner changes since the 1060.

If you have a point in the curve selected, say 775mv, then hold [⇧] and click / drag horizontally across the empty area of the voltage axis, [⇧]+[↵] gives all the points selected the same value.
