I this controller does not need flashing ...If there is red spot on controller should be flash done ..I have all phase I tested with oscilloscope ..Some memory bank is damage ,but I can't test because tserver does not support this model..I found on taobao new one tserver I think should do job ..https://item.taobao.com/item.htm?id=677015954184 I found that I dont have on 3.3 v on 12 pin EN2 ,maybe should be reason ..Logic smd I have on b 3.3 come from vrdy (4vand 11) ,vcc 3.3 but nothing on out..I change logic ,nothing change .. |

Did you check shapes of all transients on the phases? I mean all phases, core, memory and other rails? Are you sure that they work? |

Are you sure it is GPU? Maybe a capacitor or something on the 1.8V rail ? |
