X11 is the name of a chained hashing algorithm. This algorithm uses 11 different algorithms that are chained together. The first coin to apply it was Darkcoin, which has since rebranded itself as ‘Dashcoin’. The X11 algorithm was claimed to be ASIC-resistant.

The PinIdea X11 ASIC miner  hits a high speed of 450MH @ only 335watt, which is times faster than CPU and GPU mining.

 

Intorduction

The PinIdea Dr2 450MH X11 ASIC miner is one of the most powerful dash miner on market currently. The hash speed is 450MH/s and the power consumption is only 335w.

Product Display

• This is how you will receive the order from EastShore.

• Open the box.

• The miner sits in the protection foam.

• The dimension: 28.5cm x 13.8cm x 17.6cm.

• Weight: 5KG and nearly 6KG after packed.
• The metal case is made of alloy material.

• Cables and the controller are not exposed. This makes the miner simple and elegant.

• There are two 12cm PWM fans(12V 1.6A) on the front end and back end of the miner.

• On one end of the miner, there are two status lights. This end of the miner is air input

• There are two 8pin ports and ethernet ports on the other end of the miner. This end is air output.

• A closer look at all the ports.

• Fans in both ends.

 

• Screws at the bottom are for fixating the hashing boards.

• There are four plastic non-slip feet on the bottom of the miner. A closer look:

• Remove the case, it reveals two blades.

• From the front end of the miner, we can see the structure of the miner inside.

• At the top of the miner are the IO board and the controller (and two power cables for the two fans).

Performance Test

• Test screenshot: when frequency set as 450.

• Test for power consumption and noise (Test result: The power consumption of the miner relates to the efficiency of the PSU, we use the 750w LITEON Mining PSU in the test. In our test, the power consumption is about 344w with the default frequency at 400.)

Conclusion

• The design of the miner is sophisticated, sturdy, practical and of relatively smaller size.
• In a successive 7 days of test, the performance of the miner is stable. The hashing rate is a bit higher than the official released data, it hits a speed around 460M when the frequency is set at 450.
• The miner is easy to use, and it supports remote control.
• Cooling is well controlled due to the high rotation speed of the fans (12V 1.6a), the temperature of the chips is only around 30℃. Yet the decibel of the miner could be perceived as a bit high, it can be improved by changing the fans with slower rotation speed as long as the temperature is well-maintained.
• The miner is cost efficient, with 1M@0.65watt, which is 50 times of the R9 GPU miner (1M@37w).
