Four Blade Bitminer
[dropcap size=puny]I[/dropcap] wasgoed able to get a sample 1 th/s Bitmine SHA-256 Bitcoin miner to review. I got the miner from BitTech.hk. They are a fresh company on the Bitcoin mining toneel and active on BitcoinTalk.
The fresh CoinCraft A1 chips are powering the miner. They have bot popping up ter several different 1 th/s miners the last few months.
Thesis are the specs on the Bitmine:
CASE SIZE: 43.Five*44.1*16.2cm
POWER: 1300 watt PSU – 1TH off the wall 1080watt
QUANTITY: 32 CoinCraft Chips /Four Blade Modules
Typical: 25-26 GH/s
Controler Unit: Raspberry Pi Specimen B w/ 8gb SD Card
*This unit has a 1100 watt Gamezone PSU 80 Gold Rated. It had bot purchased before the upgrade to a 1300 watt PSU.
My unit arrived quick and shipped securely. DHL once again hit up the package, yet inwards it wasgoed te good condition. It has a excellent looking Blue case with slew of airflow.
Note: The unit shipped with a European power cable. You will need to get a intense duty ATX power cable if you live ter North America.
Due to the rough treating of the opbergruimte I opened the voorkant to check cables and connections. When I powered on the unit, it did not boot the OS. I dual checked all the connections and however it powered up, the OS did not boot. The Bitmine uses a Raspberry Pi to operate it. Knowing that the OS on the SD card may not have survived a customs’ “inspection”, I went looking for a replacement. I wasgoed able to find a generic CoinCraft miner picture with the help of HolyScott of BitcoinTalk, and this ended up working OK for mij.
I asked Ali of BitTech about photo availability, and he said
factory pictures will be available on the webstek very soon
Once I had the generic photo on a fresh SD card I plugged it into the Pi the system and the OS booted decently.
Your router or network setup needs to use the Gateway IP of 192.168.1.1 to access the Bitmine. My unit wasgoed on 192.168.1.111. If you do not find your miner use the AngryIP scanner or some other network scanner to find its address. The IP scanner will permit you to find it te case it has an IP te the higher registers that doesn’t always vertoning up on some routers.
Once you have your miner’s IP, just type it into your browser and the web interface opens up. I recommend using Chrome or Firefox spil you can have them automaat translate to English ter case your photo is te Chinese. Newer pictures that are coming out will be ter English.
The interface is elementary, you can waterput te your pool and worker informatie, switch the chip frequency and even the miners name. If you want to switch the IP address, you are also able to do so lightly.
Once you have added your pool information make sure the opbergruimte at the bottom says embark and kasstuk confirm.
Frequency and Title Console
Mining will begin on your pool now. It will take up to Ten minutes for the stats pagina to demonstrate current mining speed. It can take up to 1/Two to 45 minutes to fully showcase your speed at the pool. On BTCGuild, it took about 30.
With the chip frequency set to 1000 the miner shows 1.02 th/s on the unit stats screen and usually runs ter the 880 to 960 gh/s range at the pool. The HW error rate stays around 10% at that frequency. A frequency of 950 lowers the HW rate to less than 3% and the miner runs at 950 gh/s on the stats pagina and 840 to 870 gh/s at the pool.
Very first and foremost, this miner is noisy. The Antminer S2 at it’s loudest speed is not this noisy. The Avalon Gen 1 three module miner wasgoed not even this noisy at its highest speed.
80 dB at 8 feet away
The Bitmine at 67 to 83 dB 8 feet away is way too noisy. The ventilatoren just howl at high speed all the time. They are 100 CFM ventilatoren, I am going to switch them out with some fresh Cooler Master JetFlo 120 case ventilatoren. They budge 95cfm at 36 dB which will be a nice improvement noise wise.
The miner consistently uses 1020 watts at a chip frequency of 1000. With the ventilatoren at utter speed the entire time the unit stays a nice 56c cool at ambient temp of 68f. It does not have any major temp swings.
The miner is very effortless to setup and run. It does run below spec, but I suspect it is a PSU kwestie spil the supplied PSU is an 1100 watt unit. I think with a more powerful PSU the HW error rate will druppel, and the variance ter speed will close to a smaller range.
If I get a Corsair 1200 watt digital platinum PSU, I will test it with that. BitTech has already upgraded the recommendation to a 1300 watt PSU at the time of this article. You are able to add a 2nd PSU to the system. The controller houtvezelplaat and case support a 2nd PSU. Many of the very first 1 th/s miners that came out were dual PSU units. Doing this addition may help, you get more out if it at a consistent rate.
The case is very effortless to use and has lots of slagroom inwards. Cabling is effortless to route. The Rasberry Pi is a versatile controller for the Bitminer that can be programmed ter many ways. There are reports that you can even use MinePeon to run it. I may test this out te the future, and I will postbode an update if I do. I will also be attempting the factory picture spil soon spil BitTech gets it to mij.
Raspberry Pi Control Unit w/ 8 GB SD Card
The Bitmine is a solid Bitcoin miner. It under performs yet runs stable. With the improvements that BitTech has bot making to their vormgeving, the Bitmine miner will proceed to improve. Despite the noisy ventilatoren, the case is nice and the setup ordinary. Customer service is good and BitTech answers questions te a timely manner. You can get a hold of BitTech either on their webstek or their BitcoinTalk thread. I would feel comfy purchasing one from BitTech.
I spoke with Ali from BitTech he and his playmates are a diverse group and very focused on making mining equipment. They are already hard at work on making improvements to the Bitmine and working on other offerings from their fledgeling company. I will be interviewing him ter a few days spil he had a very interesting story that I want to share with you all.
