Hello. I bought a cheap damaged graphics card (GV-N66TOC-2GD) to be repaired. I think it's flooded. The PC does not recognize the card. After checking the voltage on the core is about 0.9 V and on Vram 0 V. The resistance on the Vram lines looks good (about 90 Ohm). I located and replaced the defective 0 Ohm resistor (R628) but nothing has changed. I also replaced the ncp5392p chip with a new one. The mosfets and drivers of the mosfets seem to be working . Maybe GPU flooding can lower the voltage on Vram to 0 V? Does anyone have schematic to this card? |

Hello! I got absolute identical situation, on same card. Voltage of memory do not appears, an VCORE is about 0.9v. This is my old broken videocard, Idk what happens with it, but I have no picture on screen and probably no voltage on VMEM could be a problem. I will try to follow recomendations and resolder controller or electrical key that recommended to resolder e.t.c. I still not found boardview for concretly this videocard, even in 2023. If anyone have boardview for GV-N66TOC 2 or 3GD, please, help. Thank you all for your help! |
