I'm just curious....Why are the measure points always + ? Also, how did you figure that out?
Think of it like electricity and electronics in a car:
Your whole chassis is the - and a + is pulled from the ignition or the battery to the components, wich is why when you look for a + in a car, you attach the - tip of your DMM to a bolt for example and you use your + DMM tip to test cables until you find that gives the voltage you want.
Same goes for the VCs apparently (i learned it today
). Every set of components are fed on a common end with a - and then each gets the appropriate + voltage (1.3, 5.12, etc....).
So to make it short, its your + that determines your voltage bot the -.
Does it make sense or did i make it even more confusing ? I am asking because sometimes i understand perfectly things but cant explain them at all.

Mods follow up.
Ok one 3870 moded and tested eventhough i scared myself by taking of a connection that i thought had been made by me with extra solder but no it wasnt
. So i ended up spending 1hour to fix that by using a tiny strand of wire, pfff got real scared on this one.
But the VC is working fine, i am at 1.46 on the gpu and 2.02 of the memory.
Tomorrow i mod the second card and i will take pics along the process to make the thread i promessed.
Btw here is a tip for those about to start too:
When you want to check voltages, just hook the black (-) of your DMM to your case like this you can focus on manipulating the red tip of your dmm to quickly check vmem and vmgpu. Helped me to check voltages carefully and still be able to react fast if an emergency shutdwon was needed.(one hand on the psu switch and the other one with the red dmm tip to check voltages.
More tommrow, i need to get some sleep, its 3:30am here
