Things are getting closer for KnCMiner, the Swedish mining firm that is preparing to ship 28nm boxes next month. The firm has taken delivery of the first boards to go into its ASIC miners, and is hinting that its design may allow for higher hash rates than it is publicising. Each of the boards will contain one ASIC chip, says the company. That would put each chip’s hash capacity at a theoretical 100Gh/sec. The firm says that it has overengineered the boards deliberately to cope with 320 W, even though an ASIC will only consume 250 W maximum. “Margins upon margins upon margins is what we do,” said Sam Cole, co-founder of KnCMiner, explaining his design philosophy. “There is wriggle room for lots of things.” The board has been overspecced by 30-40% for extra heat and power consumption, according to Cole. This could enable the chip to be overclocked, he adds. In a blog post, the company said that it has used a large package for its die, to ensure that it can cope with the power and heat requirements of the ASIC chips. The firm has added another mining box to its lineup in the last month. It is now selling the Mercury, a 100 GH/sec box, for $2,000 with a 250 W power consumption. Th...
