Hello I have done a clean repair of the GPU with new chipset but I recently had kernal panic .
panic(cpu 0 caller 0xffffff7f88fe19e9): "GPU Panic: mux-regs 4 3 7f 0 0 0 severity 3 WS-ready 1 switch-state 0 IG FBs 1 EG FBs 0:0 power-state 3 3D busy HDA idle : AGC GPU REGISTER RESTORE FAILED : rdar://7254528, VendorID invalid\n"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/AppleGraphicsControl/AppleGraphicsControl-3.16.19/src/AppleMuxControl/kext/GPUPanic.cpp:162
