7900GT over voltage protection?

[illuminati-hwt]

I vmodded my XFX 7900GT to 1,4v

Stock cooler + two 8x8 fan @ 5v sitting under gfx..

Measured first: 1202mv
After vmod: 1401mv

Used conductive ink and tape. Tape was used to make the conductive ink go where I wanted it to go.. Put tape on pcb, apply ink, remove tape...

I used this image as reference:



This is the result. (picture is upside down...)

Core runs at 644mhz. Warm and stable.
The mod can be undone using alcohol or acetone.. the latter works for sure.
