For anyone interested, I've played around for the last day or so with a lot of different levels of resistance. I had asked a little while back if anyone had any fixed resistor values, and nobody did.

If anyone is interested in fixed values (assuming 1.046v IDLE / 1.084v LOAD in BIOS), here you go:

vMEM: 100k (5&#37 Fixed Resistor = 2.1v ~ 2.12v

vGPU Idle: 27k (5%) Fixed Resistor = 1.17v ~ 1.20v

vGPU Load: 27k (5%) Fixed Resistor = 1.30v ~ 1.33v

I played around with VRs, but just wanted something solid for this round of testing. Hope this helps somebody out there...
