Re: Any BTC Miner (Antminer or R4) Fires occur... ever? (w/ proper elect. wiring)??
Hi, all 3 pci-e connectors were plugged in and both hashboards were operational until recently. One interesting thing is the data socket and cable was also burnt although not as bad.. so what ever happened also happened to the data cable.
Earth failed on all 6 conductors of the other 2 PCIe sockets. The earths on the data connector then started passing current because 3 * "normal" remaining cables and connectors heated up (higher resistance).
Cheap PCIe cables, undersized PCIe cables, would highly doubt it's a board fault.
Don't use cheap PCIe cables!
