Use voltmeter. You can solder a wire to vdimm read pin and measure vdimm outside the case. It is safer this way. No chance of contact w/ other component during measuring and shorting/frying any component.
The vdimm measure is in tight spot also.
this
screenshot shows where to measure vdimm (first pic yellow arrow pointing to it). go to bottom of the page "variable voltage" and you see resistor # 1.
here is the
voltmod thread and all the links and screenshots are on openning post.
If using variable resistor (trimmer), buy a
1k or 2K trimmer, the rectagngular blue color for $2.55.
Buy
this solder radioshack. it's .o15 diam 1.0oz
buy
this flux. You probably can get it cheaper @ HomeDepot.
buy wick. could find the link in radioshack, but
here is Fry's. a $3 should do it
If you solder a SMD resistor (same kind as #1 resistor in the picture), fry's has them. get the lowest watt and a 1k or 800 ohm should do it. they are very cheap. Maybe about 25cents.
That silver paste i linked before (97 cents from radioshack) may come handy. It might work as a substitute for conductive pen ($12) to short VVID pins for the vcore mod.
Let me know if I missed any other info.
EDIT: If you solder a wire to vdimm measuring soldering pin, solder the other end of wire into a empty molex to make it easier sticking voltmeter red pen into the molex. it also safer-no chance for contact to case or others. I also soldered a sowing needle to the red pen(positive) of voltmeter to make incision accuracy for voltage measuring of any board's component.
