vmod for zotac 980 extreme

[Guest Sinebrychof]

Does anyone have zotac 980 amp extreme edition that could help me to do a VR + OCP mod to this card since all this OC+ and firestorm features by zotac suck.

take high-resolution pictures of the controllers for Vgpu and Vmem and a large picture of both sides of the pcb without heatsinks

fPower limit mod is just shorting those four shunts I know. Im currently away so can you make anything from these? I will get you a picture of the vmem controller and back side of pcb later.
