1. Hashing algorithm: CryptoNight

    Power consumption: 550W

    Hashrate: 220KH/s

    These are the most conservative estimates. We expect the miners to deliver higher performance and efficiency when they are ready to ship.

2. There are financial risks associated with mining cryptocurrencies. These risks can be related to changes in exchange rate of the cryptocurrency or to changes in the algorithm that is used to mine the cryptocurrency. Please deliberate well before making a purchase because we will not accept any requests for refund for orders of this batch.

3. One major cryptocurrency which is using CryptoNight hash function is about to change their PoW algothrim, and according to their public statement, it is purposely to brick ASIC mining rigs including X3. When you buying it, you are betting that they are wrong.

4. To ensure that more buyers around the world can purchase miners in this batch, we have set a limit of one miner per user and will not be shipping orders of this batch to an address in Hong Kong .

5. Please select the correct address for shipping before you submit your order because, for this batch, the shipping address cannot be changed after the order has been submitted.

6. The shipping cost has been updated by our logistics’ service provider recently. Therefore, the shipping cost for batches that are to be shipped after April 2018 will be slightly different (likely lower) than those that are to be shipped before April 2018.

7. The shipping for this batch will begin after all orders of B1 have shipped out . The latest shipping date would not be later than May 31. We advise you to research and prepare in advance for customs' clearance in your country to avoid delays or unexpected costs.

8. You will need an ATX PSU with at least 10 six-pin PCIe connectors. There are 3 six-pin PCIe connectors on each hashing board and all three need to be connected to the PSU for the hashing board to operate. Do not connect more than one PSU to the same hashing board. Bitmain recommends the APW3++ to power the X3

9. Separate power supply to control board: there is one additional six-pin PCIe connector on the IO board which must be connected to the PSU to get power. Be sure to power on the miner only after all the 10 PCIe connectors are connected to a power supply.

1. A 180-day warranty is provided starting from the shipping date. To avail this warranty a repair ticket must be generated by the customer on Bitmain's website. Overclocking the miner will void the warranty immediately.

2. The warranty only applies to the original purchaser who purchased the machine directly from Bitmain. Once the miner is resold warranty coverage becomes the responsibility of the re-seller.

3. All sales are final. No refunds will be granted. Defective miners can be repaired for free if they fall under the Bitmain warranty policy. After the warranty period, machines can be repaired at the cost of parts and labor.

4. The following events will void the warranty:

     a. Customer removes/replaces any components by himself without receiving permission from Bitmain first;

     b. Damage caused by poor power supply, lightning or voltage surges;

     c. Burnt parts on hash boards or chips;

     d. Miner/boards/components damage due to water immersion or corrosion due to wet environment.

5. For all repairs or RMA, within warranty or not, customer must return the defective parts at his/her own expense after opening a support ticket and troubleshooting with Bitmain's instructions.

6. Bitmain will cover shipping cost when shipping a replacement unit within the warranty period.

7. If you notice there are some loose heatsinks when you receive the miner, please inform us by email to info@bitmaintech.com within 3 days from the date the package is received according to UPS/DHL/FEDEX's website.

8. Bitmain does not take any responsibility for or compensate for any loss as result of downtime caused by delays in transportation as a result of custom formalities or other reasons.
