6 of my 16 bitfury v1.2 H-CARD died over the time. October 2013 batch. no overclocking and no overheating! did someone face the same experience??
EDIT: seems to me quality of the bitfury v1.2 H-CARD (October 2013 batch) is not good enough to work with it 24/7 for a half year. some component on the card died. cards did not work again if I changed the slot on the bitfury v2.3 M-CARD.
I have 10 v1.2 cards from October 2013. One died right from the beginning and Punin replaced it right away. Rest of them works fine to this day, hashing 24/7. The weak point is the wobbly ISA-style connector (which they changed in later versions). After each moving of the miner I had to fiddle with the cards to get a stable performance back. I suppose that poor connection with the cards may have accelerated the demise of your hardware.
What about the warranty? Did you contact Punin to replace failed cards?
in my case it is not the connector between M-CARD and H-CARD's because I did not move it arround and the cards are within a case. the H-CARD's start dying from the end of the M-CARD. slot F, E, D, C, B, A. in this order. I'm fear that this is not the end. my assumption it is connected somehow with the power supply component on the H-CARD's. the cards itself has no visual sign of damage.
will contact the support. they have now a ticket system. will give update about this here in the future.
