Well, GTX580 cards are a bit cheaper than Teslas, I would say that price difference is very remarkable. In addition, floats are enough for my purposes.
>>> Other people/companies that build something similar.
Yes, I have contacted one company. They say they do exactly same things with exactly same OS and drivers with almost exactly similar hardware (they use FT77 instead of FT72 barebone) - and everything works just fine for them, no problems at all. I would have considered hardware problems - but this rig worked under XP64!
Very interesting. I would continue running 7 until you can figure it out.
Is it possible the 8th card is damaged/defective?
