Thanks to ceemic and the help of a curcuit-savvy friend, Im on this. I will probably make at least the GPU-mod this evening (+1 GMT here, so... later). I found a vMem measurment spot, and have identified the vGPU-soldering and measurement point.

Not sure Ill make anything of the mem-mod (wont make much of a difference it seems), and I need to confirm what VR to use for the GPU mod. When I do, and finish the mod, Ill post pics for you here, and anyone interested in v-modding the non-reference Powercolor 1GB "pcs" rev2.

Side note: My card clocks to about 800MHz/985MHz on stock voltage - artifact free in ATitool (haven't tried for any longer time yet, but preliminary). The temp hardly moved, so I have to assume its lack of voltage that stops me at that point.
