Cyber Bitcoin
Harley-Cloud Information Technology company was established in early 2016, it headquarter in Shenzhen released its first production, panda miner.

Some of the rising stars in the field of digital currency which has equally matched with bitcoin,try to avoid hashrate monopoly of professional miner by modifying mining algorithm.Competitive coin developers modified the algorithm makes the existing professional miner can’t be compatible, and must use computer equipment such as computer cpu or graphics card miner  which makes more people involved, more widely distributed.

In most of the improved algorithm, graphics card mining has highest efficiency, programmer calls the core of graphics chip to develop mining program, and AMD core number is much higher than computer cpu and NVIDIA series graphics card, so the performance is much better, in theory, graphics cards can support new generation of digital currency and the new improved algorithm, and graphics miner is the only one can support the most kinds of algorithm currently.

The traditional graphics miner need to buy desktop computer accessories to do self-assembly, complex hardware and software installation makes it inconvenient, the hardware part also has some mining unrelated resources, waste of energy and equipment costs, in addition , compatibility is also uneven, in such a background, the Panda Miner came into being.

Panda Miner was developed from Feb 2016, and now the developer has perfected graphics parameters on the basic of regional mature industry chain and summary of the advantages of graphics card miner on existing market,panda miner is going to be leading miner among industries.

Panda adopt 8 pieces integrated professional AMD RX 480 graphics card, abandoned some of the mining hardware resources through a reasonable design,it not only saved the cost of investment, but also make the same performance of lower power consumption, its professional design make mining be more convenient.

Official parameters of Panda Miner:
Amount of graphics cards: AMD RX480 * 8
Hashrate/Power consumption: 230MH (ETH) / 1380W; 1160SH (Zcash) / 1100W

Here comes the latest evaluation from cybtc:

1. outward appearance

The Panda Miner we received this time is for mass production (with manufacturers customized professional power version)
Panda miner adopt inside and outside double-layer carton package, printed with manufacturers’ logo on box, two hard foam board on top and bottom of the miner which has the effective protection of transporting, carton size (length 93CM * width 36CM * height 22CM).

104421sa6lagw7l7a766tb.jpg

Graphics card equipped with supper thin metal heat sink, with a horizontal wind duct which has a better performance than common aluminum thick heat sink.

104422cgeg6010d67jo8jf.jpg

The other side of internal structure is the main control board, you can see the motherboard chip and CPU.

104424mm8mrhgrtytz3yom.jpg

Here is the physical parameters of the miner.

104425zgadag2gfuyfygad.jpg

Self-contained power supply is 1600w, with 7 pieces pci-e 6 pin power plug (standard cable is 16awg). Official customized professional power supply is the Grand. Grand power supply has a good performance and its own dragon series is widely used in various types of miner.

104428qisbuk2juq8bjumb.jpg

Following are physical parameters of the power supply.

104429htvucemdi7r7tr7u.jpg

The miner we received this time weight 7.7kg , power supply net weight is 2kg, packaging cartons net weight is 2.7kg, total weight is about 12.4kg. (The above physical parameters are manual measurements, with slight deviation.)

2.Assemble

Panda installation is very simple, make power supply interfaces be full.

Panda Miner offers three major popular competing mining options at present, ethereum, Zcash, Monroe.
  Miner operation environment and the mining process has been debugged already, you just need to finish some simple settings then you can start to mine. Settings about mining Ethereum is simple, click edit of eth.bat APP on desk and then modify wallet address to your own and save it, then double clicking document ,then just start to mine.

5.Summary

1). Panda miner has exquisite workmanship, easy to use, and support remote control operation.

2). Actual hashrate and power consumption close to the official one, has stable operation.

3).For temperature, due to the short air duct, the temperature difference is not obvious from begin to end.

4). Adopt 9 powerful fans, then the noise is a little high, equip high  speed fans to achieve high stability and adapt to multiple mine environment. The actual wind duct of miner is not long, if the room temperature is low, you can chose a lower speed fan. Noise has a certain optimization space depending on temperature of mine ground.

5).Operation system (win10) has many procedures in the background, which theoretically can affect the stability of miner, so it need to further optimization.

6). Graphics card miner can support a lot of algorithms, can download mining software and configuration software on competitive coin’s official website. Theoretically, graphics miner also can support future new algorithm, coupled with the support of official follow-up software, it does have a good performance.

7).In the field of competitive currency, the algorithm is upgraded all the time,at the situation of lacking miner of certain algorithm ,for miners who want to build graphic card miner, panda is a good choice which has the advantage of stability,cost ,sustainability.
