Hi

I'm need vgpu and vmem (but also vref etc will be really ultimate :D) for Galaxy GF 6600 GE with this pcb. In next few days I will have second Galaxy GF 6600GE with another pcb so I will show her too ;) . It's exotic stuff, so I can't find any voltage mods, I hope you will help me :up:

I'm looking for "normal" vmods, but pencil will be good too :) .

Oh Massel - back to the past with this vga? :D
I hope mods will be used under dice/ln2 ;)

Dice/LN2 will be overkill, I've got all WR's now (without 3dm01, cuz I runned with netbrust cpu) with aircooled card and with only vgpu.

Most likely the mods are on this PWM bucks APW7063 which can be found on the back of the PCB. - http://www.anpec.com.tw/products/download/APW/APW7063/APW7063.htm

Connect FB pin (pin4) to GND (pin6) with 20kOhm VR set to maximum resistance. Measure the voltage on the points you've already found ;)

...and on phase (7) I can check very close output voltage ;) ?

I will try tommorow and find some pencil mods :up:

I think, you need to lower resistance on a resistor attached to FB pin (4). See PDF on that APW Dc-DC

Ok, it works. I will show later how to do it by VR and pencil ;)

So my suggestion worked? Do some documented photos, dude!
