I preset mine at 530 ohms before having an electrical engineer do it for me. Yeah I cheated. He had a pair of magnifying goggles so it was easy. I had him put it at the top of the card and run wires to the solder points so it is easy to adjust while in the case. Preset it with a dmm before having it soldered. 530 ohms gave me 1.16 volts. Just adjust from there...turn 1/8 turn and recheck and repeat and artifact check/check temps until you get where you want it. If you set it up like the pictures it should be counterclockwise for higher voltage/less resistance and clockwise for lower voltage/higher resistance.
Fantastic! Thank you.

Is the ~1.3V OVP for idle or under load?

Or does it vary around?

p.s. The Radioshack item you are looking for is a 1k-Ohm * 15 Turn Cermet Potentiometer

Item: 271-342 on front (I think this is it), and 271-0342 above serial on back
