Ok, I did the mods (lol, so much things are soldered on the graphics card now).
Alienware M17X / GTX 260M
2 Phase for GPU:
Voltage Reading Points:
1 phase for memory:
Voltage Reading points:
Memory Volt Mod (Working & Tested):
Voltage Regulator: ISL6269
From FB(pin6) to GND, R=1164 Ω
Solder a 20K VR from FB to GND.
Stock Voltage Measured:
idle: 1.57v
Load: 1.863v
After mod @ 20K (R(FB to GND is now 1100 Ω)):
idle: 1.66v
Load: 1.97v
GPU Volt Mod (Doesn't work, tried FB, FB2 and rbias)
Voltage Regulator: ISL9502
R from FB to GND = 79000 Ω
I used a 1M VR, Req (Ω) = 73000 Ω
Stock Voltage Measured:
idle: 0.907v
Load: 1.015v
After Mod @ 1M Ω:
idle: 0.907v (should be 0.99v)
Load: 1.015v (Should be 1.09v)
So my memory Mod is working, but not the GPU mod, I guess, it's vsellocked Maybe I will vsel mod it, maybe.... or not.
