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...
That's simple to know what resistance you need to get the voltage you want.

For example : Vmem
-Stock resistance before chip is 3.94k. Stock voltage is 2.04v.
If you put a 100k resistance in // with the stock resistance, you get :
Req = 1/(1/3940+1/100000) = 3.79k
Then Vnew = Vold * Rold/Rnew = 2.04*3.94/3.79 = 2.12v

If you want to find the resistance (Rnew) you need to set in // in order to get your new voltage (Vnew) assuming stock voltage (Vst) and stock resistance (Rst), just use this formula : 1/Rnew = Vnew/(Vst*Rst) - 1/Rst

R in ohms and V in volts
