The hardware bug that's existed since launch and affects the whole 64CU die (including the 56) series, including your WX series as well as aftermarket cards.
In summary the hardware bug involves the fabric SoC being fed too little voltage by the idle state VRM phase when certain display combinations are used, and is particularly prone to a fabric collapse when the card is watercooled or otherwise exposed to moderately 'cold' temperatures, or below 50C die surface cooling. Said fabric collapse triggers a complete PCIe root complex failure of the entire system in use.
