P35C-DS3R VDroop and Vcore mods here!

hey all. i found this picture @ madshrimp.


the voltage between point 1 and 6 is 22.33k ohms (according to my fluke 25 MM) - I used a 50k ohm VR/POt between the points. Set it to 20k ohm and started down from there slowly. With trial and error, I have gotten the drop down to less than .01V, almost .0v drop - soildering this is a b*tch, esp point 6, not for novices!

For the vCore mod (RED DOT), I used another 50 ohm VR/POT @ about 46.6k ohm to ground for the vCore mod.

Using the latest f4 bios

Finally figured out the %^&#$@%#$% vdroop and vcore mods P35C-DS3R - so far its working for me!

I used the "red" dot to measure Vcore:
BIOS 1,3625V - 1,353 idle/1,357 load
BIOS 1,4000V - 1,392 idle/1,395 load
BIOS 1,4500V - 1,442 idle/1,445 load
Is it possible that my board doesn't have vdroop It overvoltages 0,003V at load? CPU-Z shows ~0,03V droop and idle voltage is also lower than applied in BIOS...
go figure...
