Hello! could you please post a picture of the heatsink? I want to see how you did it.
And how are the temperatures after the vmod? Do you still use stock cooling?
Thanks a lot, your posts in this forum helped me a lot with modding my CPU! The video card is next - bios vmod
No Probs, sorry I missed this before Your PM.

I modded the GPU to 1.4v by doing a pencil mod, because my card is a powercolor
it has a better cooler to start with, so temps are not a problem, about 70 is the max.
I used 4 small dobs of Sikkaflex (any silicone that sticks, dries, and isn't conductive
should do) to stick it down, put some heatsink paste underneath and then leave some coins on top for weight for 4 hours until the silicone is dry.
I also put some double sided tape underneath around the bridge chip so no short
circuits were possible. As log as the heatsink you use doesnt touch anything other
than the bridge ic core You will be ok.
here is the link to the powercolor mod

But considering that the powercolor card uses 1.33v as default, You will have to
google for a Sapphire card mod as I doubt the powercolor one would work.
btw, I penciled the resistor instead of soldering one in where there wasn't one to
start with, these things are tiny, the pic is zoomed in heaps.
I also had to measure the resistance at that point (resistor) before pencil modding,
so I could work out what resistance to pencil mod it down to for 1.4v.
