A disconcerting discovery for a northwestrepair technician. While finishing up upkeep on an RTX 4090, he found that the cardboard actually had a bug.
RTX 4090: a bug found between GPU and PCB!
The RTX 4090s are undoubtedly playing cards with all kinds of issues. So, after playing cards that burst into flames as a consequence of a problematic 12VHPWR connector, we’re now confronted with a mannequin presenting an issue of a totally totally different nature. In truth, throughout meeting of the cardboard, an insect crept in between the PCB and the GPU. The end result was a card that was H.S. regardless of being model new!
For the report, the cardboard was purchased second-hand and with out guarantee. After plugging it in, it turned out that the air flow was totally useful, however that no show was current.
After a number of measurements at numerous factors on the PCB, the technician deduced that the issue lay with the GPU. He proceeded to unsolder the GPU, solely to find that an insect had crept between the GPU and the PCB throughout meeting.
Once once more, it’s vital to remember that this sort of incident is very unlikely. The playing cards are produced in managed environments, equivalent to a clear room. However, an accident is at all times doable. What’s extra, given the house between the GPU and the printed circuit board, it’s inconceivable for the insect to have crept in after the actual fact. Probably an worker who forgot to shut the door behind him.
Anyway, after a little bit of voodoo magic and a few critical electronics expertise, the PCB was cleaned and the GPU re-soldered. After numerous exams, it turned out that the cardboard was working correctly. Now it’s able to burn like so many others, due to a temperamental energy connector. *sarcasm*
