https://www.igorslab.de/en/what-real-what-can-be-investigative-within-the-crashes-and-instabilities-of-the-force-rtx-3080-andrtx-3090/ There may be trouble with the reference PCB spec. |

I hope there won't be hiccups with the nvidia 3000 series drivers since I just ordered 1 for myself. |

It's suspected, though not confirmed that the spec allows for cheaper large caps to be used in place of an array of 8 MLCC caps. This is the backside of the board under the GPU core for decoupling and power stability. The founders cards have 4 blocks of cheaper caps and 2 blocks of MLCC. The 3rd party cards which have only one set of MLCCs or none at all are crashing at peak GPU Boost clocks. The issue has been blamed on NVidia keeping the drivers for the 3000 series secret, even from the 3rd party board manufacturers until after they had to start building the cards. It seems there may have been a miss match in the peak boost clocks the driver pushes and what the "corners cut" AIB cards can handle. If this is indeed the case, the affected first gen AIB cards will almost undoubted receive a BIOS/Driver upgrade to clock down their cores so the peak boost does not crash them. In the mean time people are being advised, if this is an issue for them to offset their core clocks to -100Mhz or drop their power limit below 100% to limit the peak boost clocks. The rework will take months in the factories but expect updated models with marketing about these caps plastered all over them, "Fully MLCC, Gaming Ready" and similar BS.... and more RGB |

I'm hoping der8auer invests in a tweezer iron, I was getting quite twitchy he was going to lift a trace, although he's probably been saved in this case by a multitude of vias. https://youtu.be/ud6NrbJllzk?t=372 |

Has all the money to buy shitloads of new hardware but no money for second soldering iron. |O 2 good Wellers/JBCs in each hand and you could probably just lift the cap out, with enough preheat on the board. |
