Newsflash. Vmem mod seems to work, used 20k VR to ground. Used 0.2mm˛ wire.

Problem with vgpu, can't find a decent spot to solder.
Resistors too small, legs of the chip, also too small to solder on :-(
And you have to be careful, MSI printed circuits are good quality, but not great quality. (normal users don't use soldering irons on their boards I suppose)

Can someone please help looking for a good spot? It has to be connected to pin 4 of the RT8802A.

You mean vmem? It's only a tad higher with the 20kOhm VR, didn't try the limit. No cooling yet...

Blind also got busy. But it's a very difficult solder job... And crazy dangerous to rip components off...

Got new 2,2pF condenser on it, its rather big in size since it is a high voltage component, didn't find any low voltage sample :s Card works, well, at least it is still giving its output voltage. Tried to voltmod the card, but no success until now. Tried finding any component connected onto the FB pin but haven't found any, then I tried adjusting the load level but not much success either, small changes in voltage. Continuing my search
