Hello, Thanks for receiving me here ;) just discovered this forum 24h ago, hope you will be able to help me Card : MSI Armor RX 580 - 8GB - V341 - v1.3 Symptom : no display, fan are spinning, blue screen of death under windows (message is "forever loop in thread" or something like that) under linux, message "Gfx test failed" History is unknown, board is clean. I can access and flash the bios with amdvbflash REG1 is fine with 5.17 Volts output U2 voltages are 0.98V PIN8 , 12V pin 5 U701 voltage is 1.58V PIN 8 VGPU (sorry don't know the exact term) is 0.95V each GDDR Memory chip does have 1.58V under it. U900 (PGOOD) output mesuared on R900 is 2.15V => I think it is normal ? What can I check now ? Thanks for reading |

measure resistances on l900, l701, l500 and on pins 3 and 6 u300. |

About U300 in privat message. |

order by resistance. the patient is more likely alive than dead)) now there are two options - memory problems or a dying GPU. learn to test memory on amd cards. if the order is with memory, then change the GPU. topics for studying memory testing on amd cards - full theme viewtopic.php?f=48&t=100822 download link from this thread https://drive.google.com/file/d/111xZBU ... sp=sharing |

many thanks, I will read the links you provided to test the memory, hope the GPU is not dead. |

Hello, I'm here again. So I failed the diagnosys because the card is working on HDMI output (and maybe other output). we can see a "garbage screen" :  so the result under TServer is obviously "FAIL"  1) where can I see the logs ? 2) what is the difference between binaries 580 , 580a , 580g .... thanks again EDIT : ok I switched my brain on, now the results : 580 output Log details so bank D is failing ? I also read that : Failcase The connectivity between the board’s ASIC and DRAMs may have issues. The failure analysis personnel should also ensure there is acceptable noise in the power supplies. |
