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.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.
What about the warranty? Did you contact Punin to replace failed cards?
It'll be coming out of my margin, but it's not my style to change policy..
