der8auer GTX 980 Matrix Guide (Question: voltage reading via DMM)

[maCque]

Hi everyone,

 

my question reffers to a guide from der8auer, which can be found here:

ASUS GTX 980 Matrix - Overclocking.Guide

 

I would like to use hotwire solder points to measure the gpu core voltage (can be found here in the guide: http://overclocking.guide/wp-content/uploads/2015/03/IMG_6829.png).

It's clear which connection to use for gpu voltage tapping, but im not sure where to get a ground from.

 

 

I thought about to use the feedback connection point right next to the gpu voltage connection, but i assuming that would change the regulation circut already.

 

Would be great if somebody with more experience in hardmods could give me a little hint :ws:

GROUND from the big (coppered) hole just down in the picture

Wow

 

I rly not noticed that "hole" as a possible point for soldering.

So the connection would be as simple as shown in the picture I attached?

 

Thanks for your fast reply btw
