For the Pencil-Modders:

Attention!

You should measure the resistor value of the pencilled resistor (or GPU voltage) after a couple of weeks of use. We (german users) figured out, that it did DECREASE and thus, GPU voltage raise significantly!

On my card it was pencilled to 1.28V and now I it is 1.33V. Another user hat pencilled his card to 1.4V and now it was 1.6V!

Just validate your values again, as otherwise that will mean the end for the voltage ICs (and GPU of course).
