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.
