Correct, warranty is "full" 90 days except in locations where law defines the length of the warranty. Keep in mind the EU warranty is not what you think it is. I've read through it a little bit myself. I'm not a lawyer so take that into consideration.... Still, my understanding is that; After 6 months it's on the customer to prove manufacturer responsibility for a card failing. Before 6 months it's on the manufacturer to show there was no defect. So really what you're getting is a 6 month warranty -- but yes, we will follow the letter of the law in EU.
@senseless,Thank you, I think you are generally right regarding the 6 months period point. But after 6 months customer can still claim a replacement/repair service, he just has to prove the defect existed at the time of delivery. But still, even 6 months undisputable warranty it is better than just 3 months. I got used to think of it in the terms of GPU mining where the hardware is cheaper and the warranty is of normal length.
Anyway, can you tell us what Xilinx is saying about life expectancy of the FPGA board?
will there be any manufacuter service offered by Xilinx if something goes out of order after 3 months of use?
We do know what the defect rate is - but we're not going to publish that information. I can say we will be keeping a percentage of the cards in reserve for warranty replacement. It may not be possible for Xilinx to warranty the cards in a time frame that the community would be happy with. We are taking on that responsibility to fulfill the warranty obligations to make sure you get the best service.
As far as lifespan, there are people on here still mining using their spartan 6 boards. I know one person in china with like 2000 lx150s he's still mining on from the bitcoin days but with new bitstreams.
