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.

You're damn crazy...:nice:

 

Looks amazing...

I never tryed overclock NB

Feel like something is missing in my overclocking life...lol

It's not easy to compete with a C2Q against Core i7

nice:D

Soooo, as nor FB/FB2/rbias(vref) Mods are working and as I don't want to try vselmod, I edited the bios to raise voltage, I flashed the card with a 1.1v bios and a 1.2v bios, voltage raised only from 1.009 to 1.06v... not worth a new series of tests
