Blackarrow Prospero X-3 (2000Ghash/second)

Includes 20 Minion ASIC capable of calculating minimum of 2000 Ghash/secondNote: In theory the ASICs could be overclocked up to 128 Ghash/second but we cannot guarantee this until thorough testing. This would raise the speed up to 2560 Ghash/second but will increase the power dramatically which will not be supported by the supplied PSU. 2000 Ghash/second Easy to use Out of the box functionality Low power per Gigahash Compact design Ethernet connectivity Web interface for configuration and graphic reports of mining activity Supports Stratum protocol Built-in LCD to display statistics and diagnosticsAll pre-orders are guaranteed to be protected against any price decrease. If at any time, during the pre-order period, we drop the price under what you have already paid, you will be compensated by receiving more X-3 mining machines.Example: If you have purchased an X-3 with 25 Percent discount and we offer later 40 Percent discount, your order will be recalculated at 40 Percent discount and you will receive more X-3. Then, if we offer later only 10 Percent discount you will still get order as if youve ordered at 40 Percent discount.Speed: 2000 GHash/second @ TT corner (Typical - Typical)Preliminary specifications: Node process: 28nm High Performance Process Package: High Performance Flip Chip BGA Clock: 1.01 Ghz (Slow/Slow corner) Voltage: 0.85V Cores: 99 fully unrolled cores Efficiency (including leakage): 0.75 W/Ghash/secondThe integrated ASIC supports internal commands for over-clocking and under-clocking.It has been designed to be: Over-clocked with around 20 Percent. Increasing the voltage might be required. If voltage is increased, the efficiency will drop. Under-clocked to obtain better efficiency you can drop the voltage. If the voltage is dropped the clock frequency will have to be dropped resulting in slower hashing speeds.
