Black Arrow Prospero X-3 Asic Miner 2000Gh/s

Product Description
Includes 20 Minion ASIC capable of calculating minimum of 2000 Ghash/second
Note: 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 diagnostics
All 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% discount and we offer later 40% discount, your order will be recalculated at 40% discount and you will receive more X-3. Then, if we offer later only 10% discount you will still get order as if you've ordered at 40% 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/second
The integrated ASIC supports internal commands for over-clocking and under-clocking.
It has been designed to be:
Over-clocked with around 20%. 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.
