Hi, having no way of adjusting the voltage on the pcs+ through the use of software (tried ab, ati gpu tool) since apparently the uP6219 controller is not software.. controllable, am now hoping I can up the voltage through a volt mod.
I have never done a volt mod before so it seems kinda scary.. but from what I've read here, connecting a resistor to the fb (not sure what this is.. an input or output for the voltage to the vgpu from the controller?) and then grounding the resistor either to the pcie power connectors' ground points or some other spot to increases the resistance, which I think is supposed to trick the regulator into increasing the voltage it puts out... or something like that... sounds simple enough... sort of anyway.
Is the volt mod shown here, the one on page 1 with the 50ohm trimmer (resistor?) for the core be possible on the powercolor 5850 pcs+ (http://www.techpowerup.com/reviews/P...CS_Plus/3.html

I understand soldering stuff on the card risks destroying it, but can just using a multimeter on the card alone do damage? Just curious.
Oh and how reliable is volt modding...
-does it cause issues with drivers?
-reduce longevity of the card.. say an increase to 1.25 on the gpu so nothing too extreme?
-does it disable powerplay I think its called.. the thing that reduces clock speeds on idle?
