Good day experts. i have bought a pcb RTX 3090 galax hall of fame, pcb has 12v, 5v, 3.3v and 1.8v present,. and Nvdd, msvdd, fbvdd and pex are missing., As per the seller the pcb is fully functional yet it is not, now he insist that it will not work untill i put a gpu chip on it,. i am confused as per other brands where the pcb is fully functional with all voltages without gpu chip and vram,. Does anyone know if this specific brand has anything different that it will not raise the voltages without gpu chip..? Thankls |

На некоторых платах без видеочипа напряжение повышается выше нормы, плату нельзя включать без видеочипа, иначе видеопамять сгорит. |

Ok, yes, i only see msvdd raises to 1.7v and then drops down to zero, but nvdd and fbvdd stays 0 and pex also at 0,. So..? is this behaviour normal..? |

Зачем так рисковать, видеочип нужно установить , если боитесь испортить рабочий видеочип, можно установить неисправный с подбитым каналом видеопамяти для проверки напряжений. |

ruzalit писал(а): Why take such a risk, the video chip needs to be installed, if you are afraid of damaging the working video chip, you can install a faulty one with a damaged video memory channel to check the voltages. Yes, i do not want to risk the chip, i dont have any other damaged chip,. there is no video memory on the board so that is not an issue, i just want to be sure if this behavior is normal then i can install the gpu chip on it.. |

Скорее всего без видеочипа на шим не приходит сигнал en для включения. Вам придется установить видеочип. |

Nope. Nothing. After planting chip nvvdd, fbvdd and pex did not came on. Only msvdd rises and goes back down to mv. |

Надо было проверить сначала порядок появления напряжений power sequence , 3.3v, 12v, 5v, 1,8v, nvvdd, pex_vdd, fbvdd Возможно, отвалились детали платы, неисправен DRMOS в цепи nvvdd. |

Thats correct. But as per the board did not started the seller did not agreed to test or repair further. He just took it back and i just gave it without asking if i need to measure anything. He replaced it with asus strix pcb which is functional and i guess the HOF pcb he returned further to someone. |
