X11 is the name of a chained hashing algorithm. This algorithm uses 11 different algorithms which are chained together. The first coin to use it was Darkcoin, which has since rebranded itself as ‘Dashcoin’.
The X11 algorithm was claimed to be ASIC-resistant. However, check out this hottie! The X11 ASIC miner, it hits a high speed of 450MH @ only 335watt, which is times faster than CPU and GPU mining.
Let’s say, it’s a revolution for x11 mining.
The PinIdea Dr2 450MH X11 ASIC miner is one of the most powerful dash miner. The hash speed is 450MH/s and the power consumption is only 335w.
|Hash Rate||450 MH/s ± 5%|
|Power Consumption||335W + 5%|
|Fan||2 x fan|
|PSU||NO integrated PSU, need a PSU > 400w with 6pin x 2 or 8pin x 2.|
- This is the miner you will receive.
- Opening the box.
- The miner is set in the foam, so there will be no damage risk during the delivery.
- The miner is a quite small, the size is about: 28.5cm x 13.8cm x 17.6cm.
- However, the miner is quite heavy. The weight of the miner is about 5KG, the weight will be up to 6KG with the package.
- The miner is designed as the short cuboid. The case of it is alloy material and black semi-matte paint. This lets the machine seems on quite the scale.
- There is no any other cables or blade or controller on the case of the miner. All the cables or controller are hidden inside the case of the miner. This makes the miner very concise and clear.
- 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 lamps. This end of the miner is where the cool wind get in.
- There are two 8pin ports and ethernet ports on the other end of the miner. The hot wind will be exhausted from this side.
- Let’s take a closer look at all the ports.
- And the fan-in-fan-out
- There are some screws at the bottom of the miner which used to fix the hashing boards.
- And also there are four rubber plastic non-slip mats on the bottom of the miner. Let’s take a closer look:
- When we put the miner on the ground, the non-slip mats will protect the miner against scratched by some other hard things.
- Opening the case, two blades are showing.
- From the front end of the miner, we can see the structure of the miner inside the case is quite clear too.
- At the top of the miner are the IO board and the controller (and two power cables for the two fans).

- 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(400) set.)
- Test video: https://youtu.be/e0E07tfSwSc
- The design of the miner is sophisticated, sturdy, practical and with relatively small size.
- After being tested for a week intermittently, the performance of the miner is stable. The hashing rate is a bit higher than the official released data, it hit a speed around 460M when the frequency set at 450.
- The miner is easy to use, and it supports remote control.
- Cooling is no issue 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 of environment well-maintained.
- The miner is cost efficient, with 1M@0.65watt, which is 50 times of the R9 GPU miner (1M@37w).
