Via last month X type RK-BOX,Xiao Qiang has newest type X3 miner here. The same Frycat's third generation chips, integration of the four boards,each has 12 chips,450g-480GH,Power 500W. What are the differents in the Miner X3?  Here is our evaluation.

1, Open picture

rockxie's integration miner has double bubble box packaging, a full range to ensure transportation safety.

With the machine packing accessories include: four the USB data line, raspberry pie and raspberry pie acrylic box, data line, power line. There is a USB-HUB box which fixed upside in inside of the miner box.

Here is two pieces of 45 degree angle picture, according to machine using classical design, can see, is it right someone which we like?

Next is the machine specifications:

One of 12cm high speed fan is in front of the miner box. The four line with temperature control.

There is an air outlet, the fins make the heat sink seems so threatening gestures.

Put raspberry pie into its acrylic box, then power line. Attention to the power plug in the most outside three sets of 26pin needles, each parallel has two needle, red line outward as shown

Put raspberry pie into its net line and power line

Connect the machine above USB-HUB, raspberry pie power interface, following on which I made signs, you can not miss it.

Debugging chapter

Power on, oh, let's has a whole picture, can you see all lights in raspberry pie board? It just begin work. ( quite pretty in night)

Go to the web service of the miner, which is default ip:192.168.1.254, the opening page is same as old PK-BOX.

Test

Measurement the power, temperature and noise, test room has 32 degrees, humidity 56, background noise 41 dBA, the miner with contorl has live power at 527 watt.

135457q6d33up3p2zpd6c2.jpg

The highest machine temperature is in the inside end of the miner box. Here you can see the heat sink temperature is 45 degrees.

135637ie5nyyloqfb4f5ez.jpg

Temperature in the outside end of the miner box is about 36 degrees.

Noise, it is 73.2 dBA on the box.

135753c6b3qq9qzobdhh6q.jpg

It is 76 dBA when zero-contact

135819wt3pcc3tp3nnxtt7.jpg

It is read 70 dBA where is distance of 20 cm to the miner.

The summary

Apparently, Xiao Qiang's new blade is in the X type new miner based on RK-BOX transformation, the same four Hash board and the same set interface, GH/s level is the same. This transformation of the advantage is that the machine heat could be move out more faster and more effectively so that the stability of miner improved. And the body design is more conducive to large-scale deployment of mining. The measured also reflects this conclusion: the highest heating temperature drop of 5 degrees than the original RK-BOX miner, and the miner has live speed in mining pool than the original Biao high above 20GH/s. In addition a raspberry pie distribution acrylic box is good, to avoid in the process of using the bottom conntact metal by short circuit, it is good for protect. Noise level test,  of 0 distance voice, I put home electric fan as one of comparison, at the strongest four wind lever, it is the same as the miner machine. So that if at distance of 3 meter, the noise lever is same as home electric fan.

Two problems are found in the testing process: 1, The USB-HUB data line has  pressure to machine frame (Figure), although does not affect the data, but also belong to a point defect. 2, The temperature of heat sink in the end of miner box has a little high since the lenth of whole machin. If the room temperature is high, a extra fan is suggest to add to the end of the miner.

Received the factory notice after our test: the newest machine, has 2.54 4Pin cable to the MSU, not the Mini USB interface. By one 2.54 , 4Pin cable ,it can make the data transmission more stable.
