eVGA 9600GSO Dual-Slot volt mod?

[largon]

OrangeGator,
The VID-mod changes vGPU without the VR.

Please see/measure if the pads on which VID4-resistor was mounted on are still connected. Like via a tiny bridge of solder.
That would explain your voltage drop as VID4 makes quite a difference:
1.31250V is VID0: shorted (0), VID1: no connection (1), VID2: no connection (1), VID3: shorted (0), VID4: no connection (1), VID5: shorted (0) and VID6: no connection (1).
And VID for 0.93750V is the same as 1.31250V, but 0.93750V has VID4 shorted (0).
