Thanks for the pic Skaaz.
Is it sufficient to measure the voltage from the backside of the chip on a pinheader?
I'm guessing no, but i really dont have much of an idea.
The reason i ask is its pretty much physically impossible from what i see to measure the point 'LFRAME to modchip' on the zoomed pic (yellow) with an X3, as the chip 'covers over' this track (top-side of mobo).
Measuring from the underside would seem quite teadious, however if I want to try it out, do i just go for either of the points where the resistor is to be soldered?
