The Ark Customed 1.5T miner in large stock!

 2T bitcion miner in stock!

Welcome to contact us!

This is 6 module. 5 module can overclocking.
And our this miner can enough reach 1500G/HS. You can try to use 1.5T, it is not worse than 1T.

This is The Ark customed version, the light is red . the Power consumption is 1127w.

Under the current caculate power soaring, mining more and more difficult. Under the Bitcoin market deteriorating situation , Bitcoin mining machine not to the past, to fight at all costs to calculate the force , now have to fight price-performance , mainly shows on single G power consumption. End of life in the mining machine to dig out the difference between currency and electricity. When the difference is 0 , mining machines have shut down, so power consumption indirectly reflect the life of the mining machine . 1T machine such as a daily output of 0.018 coins, electricity 24 degree a day, a half- count force 1.5T, producing coins .027 , electricity 36 degrees one day , when the currency * 0.027 < 36 * electricity prices, the mining machine on there is no need to continue to go on a dig ;If the force is also considered a low -power 1.5T mining machine , the same yield 0.027 coins every day, but power is reduced to 1100W, electricity 26.4 degrees one day , saving 10 degrees , apparently low-power mining machine life to be longer , for under the mining machine for the buck in a down- state work , physical life is certainly longer , at the same time stability will be strengthened. The evaluation of the mining machine for Ark customized version of A1 Minerals 1.5T ( low power consumption ) , due to the limited testing time , the measured data will inevitably be one-sided , welcome ore Friends correction.

Put the funds to escow is good.

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.

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 .

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 .

Figure 7 eight module chip temperature

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 .

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.

Dragon ore mining machine (five modules T- class) overclocking IMG installation configuration instructions

1.There are some questions need to make sure before overclocking:
(1) Whether your T-class miner can overclocking?
This IMG is for the first few batch of dragon ore mining machine five- module, only five-module machine have a promotion effect.The method of making sure five-module is simple, from the case to inside the mill, if you have five pieces of circuit boards, each circuit board have the green light, it is five-module; Also can be in the mill console applications, click on the "real-time monitoring of mining machine" button, open the mime interface, view how many the modules are. As shown in figure 1, 0 1 2 3 4 ASC for five-module mill. If only 0 1 2 3 ,it is 4-module machine, the following article dont need to waste time to read.

(2) How many your miner overclocking to?
According to different module constitution, the overclocking figure in 1.08 T ~ 1.25 T (this data is the newest data after we ourselves overclocking 213 miners,less than 10 miners cant overclocking 1.1 T, most in 1.125 T;another batch of 98 sets of good constitution, directly on the 1.2 T, because of there is no power supply,it not top to 1.25 T).Although the same ore machine,there is bigger difference between each module constitution , so set respectively the frequency of each module in the overclocking package,to adapt to the different physical modules.
(3) How to determine your miner constitution?
Overclocking a period of time, in real-time monitoring interface, check the error rate of each module,that is to say DH or HW,if less than 6%, the constitution is good;if is 0% that is very good;if more than 10%,it is better to not overclocking.We adjust each module frequency according to the DH values, so that digging the potential of mining machine maximum. Normally we control within 8% of the DH.
(4) Do you charge the IMG?
IMG no charge, but need to register when using, registration requires a small fee. In the spirit of sharing,the IMG without registration provided in the appropriate time after a month. If you have sufficient funds,you can spend to register;if you don't want to spend money,you can use wait for period of time.
(5) What extension functions of the new IMG ?
In addition to the official automatic mining and difficulty setting function, we are making remote monitoring function module,it is free upgrade after completing.
(6) Whether manufacturers guarantee the wattanty after upgrade?
Because of no seal on the five-module miner,we guarantee the warranty after openning the box. But IMG update background interface changes, the official is not warranty.So it's better to purchased a high-speed 8G SD card (30M speed) to make a new system, the original SD card to save good, once mining machine is broken, install the old SD card back and returned to the factory warranty.

Upgrade IMG instructions:
(1) Download overclocking IMG and writing SD software tools.
Overclocking IMG download address: login Ark mining station network location (http://pan.baidu.com/s/1ntpxbBj), into the "dragon SD_IMG ore mining machine" folder can see overclocking IMG, as shown in figure 2.

There are two files in Network location:one is the writing tool package Win32DiskImager,the other is "fz49 overclocking. Rar" dragon SD card of ore mining machine overclocking IMG compressed package. To download the two files to a free space of more than 8G plate,decompression respectively.
(2) Burning SD card
Insert the SD card to card reader, insert the card reader to the computer (if it is right, then the computer should add a mobile disk, my machine is J, open Win32DiskImager.exe, as shown in figure 3.

① select the disk whith the card reader in  (if card reader connected properly, then open the program, the program  will automatically selected, without change)
② select the image to write to file
③ press the button "write" to write, when prompted to rewrite the entire content of the SD card, press OK.
Writing process need a period of time, depending on the image file size and speed of reading card.
(3) Install the SD card
Open the chassis (take the case on the surface of the top eight screws), remove the old SD card on raspberries, safekeeping, in case of warranty. Put on the new SD card. As shown in figure 4.

(4) Equipped with power supply
For the question of whether or not to need to add power supply, the experiment has proved that each module overclocking 900 frequency,no need to add power supply.If mining machine constitution is good ,after overclocking 900, DH still not high, friends of mine ready to hit the 1.25T , must add power supply. This site is to use the server blade power conversion, output for two 6 pin heads, mill power supply line is divided into two kinds, one kind is with tieline, this direct turn 6 pin electrical source on interfaces. As shown in figure 5.

Another kind of power supply interface is the power cord directly on the 8 pin mouth of module,the 6 pin head can't directly to the module,power supply is negative,cut the line of 6 pin head,exchange the yellow and black line. After that,pick up 6 pin head on the module 8 pin,empty two mouth.
The original power supply with four modules, extra plus power with one module, 3 + 2 is also possible, of course. Attention to boot, first open with extra power supply,then open the main power supply;when power off,first close the main power supply,then close extra plus power supply.

3.Registration and setup instructions:
The default IP for new SD card is 192.168.1.10, use this IP login to mill the console interface, software registration screen appears as shown in figure 6.

If the registered ID is 88888888, the system has not yet been read mill information, please open the console or refresh a few times. Until out of something similar to figure 6 registration ID, click on the "click here to get registration code" link, enter the registration screen, as shown in figure 7.

According to the customer service provided by the login account and password to register background interface. Click on the "software registration" - > "add registered",copy the registered ID on the mine. As shown in figure 8.

Finished, click "submit" button.
You can see the registration in the registered list. The registration code is copied into the mill background registration code box. Finished, click "submit registration code", can be set into the interface. As shown in figure 9.

Then according to official instruction to set mill,everyone knows,we will not say more here.

4.The renderings after overclocking
Three prototype, BTC1 blue line not overclocking, BTC2 super to the black line 850, BTC3 super to the green line 900. All without power supply. Specific overclocking evaluation, this website to open another post for detailed explanation.

dank u !

To expose fraud skpe account: nite hawk，email:<sickwitit101st@gmail.com>
I am webmaster of www.fz49.com, We are miners , we produce  mining machine and sale . Now we to expose a liar, I hope you be careful of this person.
1、Cause: one is called account (BBS) buyers to contact us, said there was a 150 mine machine business to talk about, He said to use $750,000 to buy  150 units 1T-class mine machine.
2、Con process: in the continually negotiate business, he asked us to gave him 200 BITCOINS as a mortgage first, or 150 machines to help him to dig for 14 days. Then he will send us those cash in the form of express mail. ( Does he think we like dogs that are easy to be cheated ? )
3、 In order to prove that we do have so many machines, I even took a picture to the mine to him.



4、Exposing process: in the communication I continue to find his various suspicious, so I decided to design a bait to him. I told him that I could show him the mine pool data of our 150 mills running . Then I told him about my 150 mill miners’  account and password (of course the wallet address can't be modified, because of need our email confirmation).as a result, after I told him, he immediately changed the address of my wallet.


5、Threatening me after being revealed:
Although his cheating not succeed, but I hope that man his threatened-email mentioned can be alert.

Dragon Mine machine (1T -class mining machine ) forget the IP or IP chaos solutions:
If you forget the IP of the mining machine , you can view the IP of mining machine LED screen on the display . If setup is complete, the system also did not write the disk , at this time the mining machine was shut and restart, which will lead mining machine IP lost. Then the mining machine LED screen displays a random IP. Because of don’t know what is the machines’ subnet, so can not ping the IP of mining machine , resulting cannot log in the background interface of mining machine .

Fix: Rewrite the SD card. To do the following:
Login in Ark mining station network disk
(http://pan.baidu.com/s/1ntpxbBj),
into the " Dragon Mine machine SD_IMG" folder. There are two documents in that folder, one is software package of write disk tools “Win32DiskImager” , the other is IMG archive of  Dragon Miner’s SD card . Download these two files to an empty closed space over 8G , decompress respectively .

Burn Writing SD card
Insert the SD card into the reader, the reader into PC computer ( if correct , the computer should be added to a removable disk , my machine is H ). Open up “Win32DiskImager.exe”, as show in the picture:

( 1 ) Select the disk reader resides ( if the reader is properly connected , then open the program, the program will automatically selected , no change ).
( 2 ) Select the image file to be written.
( 3 ) Press the button "write" writting , when prompted to rewrite the entire contents of the SD card , press OK.
Write process takes some time, depending on the image file size and speed reader.
