A large number of Radeon RX 6800/6900 series graphics card damage seems to find the reason
After investigation, these graphics cards also have one thing in common, many of which are from the same seller. Since these cards all look very new, it’s likely that they were recycled and refurbished before being resold. What is even more unexpected is that crypto mining may not be the main reason, and long-term storage in a high-humidity environment has a greater impact, which also explains why GPU cracks occur. Presumably, these graphics cards have been stored in high humidity for weeks or even months. In addition to the storage environment, climate change during long-distance transportation is also worthy of attention.
These Radeon RX 6800/6900 series graphics cards are likely to still function normally after retirement, but the poor high humidity storage environment allows them to be “soaked” in water, and there is no proper dehumidification operation during this period.
