I have a serious problem with my brother's gpu, the memories are gone. I switched to samsung. Something happens, she starts the pc but does not pass image on the monitor. using teamviewer it appears, samsung memory appears and neither bus nor bandwidth readings appear. what could it be? any resistance that remains to change in the controls? put in 0 0 0 1 0 0 |

PT-AH Measure the resistances across all main supplies (picture in attachment) Check the presence of voltages and the quality of the PWM converters with an oscilloscope. |

chip GP104-300-A1 but I have a line that has 0 ohms Link image: https://ibb.co/9cd4HWj |

I have been measuring and everything is ok. it seems to me something with a problem with the bios chip of these readings |

PT-AH Leave the bios alone, you can only aggravate the problems  It is possible you have a problem with PCI-E Swap PCI-Ex16 slot for PCI-Ex8 or test motherboard for AMD By running 30 test mods from under the integrated graphics (at least 4GB of RAM) mods will show if you have a problem with PCI-E. Instructions for using mats-mods here (in Russian but in pictures): viewtopic.php?p=897863#p897863 Check the presence of all voltages and their quality of operation of the PWM converters with an oscilloscope. |

I'm going to buy the oscilloscope to deal with it and until then the graph will stay leaning and follow your directions this repair will be paused... |

Good luck to the whole team. well I bring here a repair that everyone finds suspicious. her fault is that she had errors in all memory banks. I replaced it with new memories. they told me it was a controller defect, after all this time in analysis I found the error and removed the error. Because there is something that is defective on the PCB that causes this error. It doesn't give as burned, but it also doesn't give as impeccable in terms of values. also for fun I changed something else that left me the 1070TI with 1911 mhz always, whether playing or benchmarking. But for this I think that for it to be at 100% I will have to change the VRM, because the mosfets scream a little. in benchmark heaven it always gives above 118 fps while the rx 5600xt goes at its 87 fps. It seems that not even with raw air OC and with 190W no one has done this... Memory banks after repair: https://ibb.co/Bzgwd6S GPU-Z: https://ibb.co/3cKjxPW bench_fps_test: https://ibb.co/0ZFk3Hq knowledgeable in these matters, will it work? |
