Topic: Ark customized version of the A1 Miner (1T 2T) evaluation (Read 2288 times)

Amazing how all these 'new' 1th/2th+ miners all turn up out of nowhere for sale just after they aren't worth the metal they are made of why don't they just say 'we are now selling our entire mine after we have mined the shit out of it, any idiots interested?'

wtf...

There is no guarantee!!!

My 1150w power is broken.

Answer from 被遗忘者 [email protected] is:

"You can go to buy a local 1150 w power for replacement ，Even more so that you save money"

 Shocked

Anyone purchase and receive these units?

Feedback would be helpful from customers.

Dragon Mining launched early 2014 's first T -class mining machine , the core chip is 28NM standard A1. Now six months later, the dominant T -class mining machine market is still the A1. A1 chip in the mining sector a good reputation , price sets straightly from high above 3.3W to now more than 6000 yuan. The evaluation of the mining machine for Ark customized version of the A1 mining machine , there are two sizes , namely 1T and 2T mining machine , the paper describes the parameters 2T machine-based custom machine . A1 Miner old miner who are familiar with some common arguments do not do a depth evaluation of different customized version of the Ark , we will detail the evaluation.Ark customized version of the A1 mining machine used superior grade A1 chip , overclocking ability, run over the next clocked 1000 cases , HW is very low, which is higher than the market some of the biggest advantages A1 mining machine. Due to the HW is very low, four modules in the mine pool has a sufficient amount of calculation power 1T , eight module 2T miner operators have sufficient force 2T . Some small mining machine manufacturers produce A1 mining machine due to excessive lead mining machine HW background display 1T enough to mine pool only 970G even lower.

1, the mining machine appearance and workmanship
Mining machine size slightly larger than A1. The different with A1 is the whole machine has 10 fans, thus ensuring that the machine's cooling machines , mining machines with a total weight of 24.5 kg packaging . Overall mining machine shown in Figure 1.

Figure 2 mining machine size comparison

Mining machine from Shenzhen,China renowned provider of industrial solutions , strength and understated by large OEM production, excellent workmanship . PCB board red light, mining machine running for the indicator is red light.

2, the software control system
Ark customized version of the T -stage mining machine, using raspberry send + Linux raspberrypi 3.6.11 operating system , you can use putty ssh to log into the software with raspberry linux system, or WinSCP FTP log on to the system to view or modify raspberry files. Background interface shown in Figure 3.

Ark customized version of the T -stage mining machine mining machine with the previous A1 backstage different places , there is the chip supply voltage regulation and mineral card ( module ) frequency adjustment , the miners can be fine-tuned for each module according to the chip 's physical . We basically did not move these parameters , because the next parameter manufacturers factory settings, mining machine HW low temperature at the South China 10 days of continuous operation , stable and efficient.

3, the data mining machine running
1), the average count force
Randomly collected twenty-four hours the two mining machine operator force curve , the mineral pools tested for G pool , shown in Figure 4 . The black curve is above 2T custom mining machine , below the blue curve is the 1T mining machine , it can be seen from the figure, the two machines are sufficient ore mining machine.

Figure 4 count force graph

2 ), the wall power
Mining machine with two 1100W power under the gold medal , adequate work force 2T count state machine measured power 2060W.

3) , the noise decibel
A total of 10 fans ( includes two in power supplies ), eight is violence fans to make mining machine cool. The sound of course is quite spectacular . Found 71.1 db noise figure , as shown in Figure 5. This is completely unsuitable for home or office miners. Mine is only suitable arrangement count force .

Figure 5 dB noise

4), mining machine temperature
When the ambient temperature of 30 degrees , measured with a thermometer outlet temperature of 38 degrees. As shown in Figure 6 .
http://www.fz49.com/data/attachment/forum/201408/03/114751gh40h6kkgmi82swn.jpg
Figure 6 outlet temperature

At ambient temperature reaches 38 degrees mine , the measured outlet temperature is 42 degrees. Chip highest temperature near 65 degrees , usually around 59 degrees. For stable operation of the mine has been ten days temperatures 2T mining machine background monitoring in Figure 7 . Now is the hottest weather in South China, mines more than ten units custom machine, stable operation for so long, this evaluation shows a custom machine can survive the hot summer months .

5) , mining machine error rate
In the case of long-running high temperature , maintaining a low HW, is to ensure that a sufficient amount of calculation power premise. Run ten days of the error rate shown in Figure 8 .
http://www.fz49.com/data/attachment/forum/201408/03/193204idqiddihzqkxlliz.jpg
Figure 8 hardware error rate

Error rate of eight modules are below 0.64% , the overall error rate at 0.54% , this parameter is quite other vendors A1 mining machine , it is commendable one .

After twelve days , in the mine environment for 12 units Ark customized A1 Miners ( six 2T and six 1T) field evaluation. During this days, there mine friends purchase two miners. Twelve machine, out of the box shelves run , all up and running. There is one 1T mining machine operator is not compliance , it is a module defective upon inspection , for unknown reasons , two days later put on a new module to work properly. We conclude that: mining machine can run at full capacity and stable Southern High temperature weather , the failure rate is very low , the biggest bright spot is the hardware error rate is low, the disadvantage is huge 2T machine noise.
