"no I did not stick a variable resistor in there, not yet.
I just solderd a 4.7K resistor to a wire, to a SMD grabber, then shoved the resistor into the hole of TP503, then grounding it with the SMD grabber to a ground pin on the motherboard, and it was done.
you can measure it, from the leg of the black box, just above C47. not sure what that thing is... but thats where you measure it. this mod required no soldering, just make sure you don't knock the wire off, or you might just kill the whole thing... SMD grabbers should be used with some caution, cause if they come lose, your gonna wish you just solderd it on.
I went from 1320, to 1370 on my ram, by this mod.
that was with the 4.7K resistor, I didn't try anymore then that.
I can say however, at 1.9 volts, the ram did get rather hot."
