Hi everyone! And a happy new year:)
I bought this device and actually iam not really satisfied with its work. The problem is that it's hash rate on controller be and pool differs very much. This way iam loosing up to 30% of hash rate. For example be speed first week - 3-3,2th, pool speed 2,7-2,9. And last two days the device productivity dropped to 1,7-1,9 th - pool speed, Be - Device speed 2,4-2,6. All boards work and chips have no power downs. Environment is good temperature (about 15 Celsius degrees) and power is enough. What can be the solution for my problem? Thanks for your help

If someone wants to see unit by own eyes, welcome to Shenzhen.
Do you have a shop/outlet in Shenzhen or is this an invitation to visit the factory? I'd be interested in either one.

What pool are you on? Hi! Iam on btcguild. Contacted manufacturer representative in Russia and their worker Artem replied that thair device works perfectly))after he looked looked on screenshots from be controller and from my account on btcguild.. The difference of speed on screenshots is 1,7 th (pool) - 2,6 th (be); 2,4 th (pool) - 3,0th (be); 2,8 th(pool) - 3,2th (be) were not familiar to him. I also informed him that The rest of equipment (lkte - 1th(6pcs), rockminer t1 (3pieces), prism (3 pieces), s4 antminer (8 pieces)) works without such troubles and shows same correct gh on controller and pool. The answer I received from him was fast but useless : instructions for non-btcguild users Answer >>>>>>> How to run on pools other than ghash.io and btcguild with Raspberry PI and bfgminer 1.Modify /etc/apt/sources.list on your Raspberry PI deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ wheezy main non-free contrib deb-src http://mirrors.ustc.edu.cn/raspbian/raspbian/ wheezy main non-free contrib 2.Update the aptitude package on your Raspberry PI sudo apt-get update 3.Download bfgminer wget http://luke.dashjr.org/programs/bitcoin/files/bfgminer/4.7.0/bfgminer-4.7.0.zip 4.Uncompress unzip bfgminer-4.7.0.zip 5.Install dependencies sudo apt-get install autoconf libtool libncurses-dev yasm curl libcurl4-openssl-dev libjansson-dev pkg-config libudev-dev uthash-dev libusb-dev libevent-dev 6.Enter bfgminer directory cd bfgminer-4.7.0 7.Run configuration ./configure 8.Compile bfgminer make 9.Run bfgminer ./bfgminer -o stratum+tcp://stratum.f2pool.com:3333 -u <workername> -p 123 --stratum-port <port(3333 by default)> --set-device PXY:diff=<difficulty(16 or above recommended)> 10.Set static IP for Raspberry PI(modifying /etc/network/interfaces) Take the IP address 192.168.0.100 as an example. Replace iface eth0 inet dhcp as: iface eth0 inet static address 192.168.0.100 netmask 255.255.255.0 gateway 192.168.0.1 netmask and gateway are decided by your Raspberry PI's local network settings. 11.Configure ethernet controllers Same example as above. Modify the pool address on ethernet controller to 192.168.0.100 with port 3333. >>>>>> So the problem remains open for me and any experienced advice is highly welcomed:)

Plus look at that constant 2500 watt power load, you would be hard pressed to even run this thing on a home outlet.
Do remember that the US has unusually bad circuits. Dogie, an ignorant statement like that, makes me wonder the level of knowledge you are relaying through your numerous (paid via amazon associate tag) reviews. As an electrical engineer having lived in the U.K, Australia and the U.S, I can say the worst electrical circuits and standards are by far in the U.K. Australia follows close behind with some of the best located in the U.S. I'm not saying the U.S excels overall, and I can name many areas they could improve on, following international standards for example, yet when it comes to residential and commercial circuits, the U.S cabling has a higher over rating than others by far. Are you.... are you honestly trying to argue that the USA's 110V 20A (16A 24/7) = 1760W is better than the UK's 240V 32A (36A 24/7) = 8640W for bitcoin mining? and that equals a bad circuit? No just different designs. So basically because the USA uses 120 vs UK's 240 it has bad circuits? The more shit I read from you just confirms it's just shit. anyone competent or with a big enough wallet can easily rectify their electric situation in the USA.

Hi, At 260 MHz device has same real output as at 280 or 290 or 300MHz. Means When I make the frequency higher then 260mhz - the device doesn't go up in real performance - only the expected performance goes up. Now testing the device on ghash and will post here my experience after 24 hours. Also will clock the device up to 280mhz so can compare shots from be controller and pool.

Every house has a two single phase 120v drops from the grid, if both wired to a plug you get 240v from the 180 degree offset on the phase, if you only use one you get 120V and the other leg gets wired to ground/nuetral. I am sure you might be able to find a house that was built when Tesla and Edison were still alive and it might be 120v, but for 99% of the home grid upgrades have given everyone 240V in their homes. Very easy to change a 120v plug to 240v move the nuetral to the other hot leg with a 2 pole brealer and change the plug on the end to a 240V prong and presto 240V in the USA at your house.

I too debated this with dogie a while ago. He is based in the U.K so has little first hand knowledge. He argued that most have no idea and the standard was 110v. The best way to describe the layout in the U.S is split phase 220. ie. 110 each split phase. (source, electrical/electronics engineer in the U.K, Australia and the U.S). As long as we aren't talking about 3 phase (which is becoming more common around the world in domestic premises), most single phase power supplies will work happily at home. I say most as some still have the tendency to produce that magical smoke at near full loads.

This company is a scam. Its good that received my device back in Dec 2014. First of all the device isn't hashing as announced, its real hashrate is 2-2,8TH depending on conditions. I made a big examination of its work on different pools and on different clock speed but it only proved that it isn't hashing properly due to problems with soft. First they replied me they know about this problem and will sent me soft update but it never happened. But I thought it isn't the biggest issue and continued using the expensive device until in February 2015 troubles with one of it's two PSU's started. First I couldnt extract it from the miner body and it was really not fun. The guy that helped me to buy this miner and earned his 100$, had to buy me a new PSU from his earnings, bcs official support ignored his baggings to provide a warranty support for bad PSU. Next thing I Have to say about The engineers who constructed this massive thing are ass-handed "engineers" who didn't even made simple analysis of hot wind extraction. The vents from PSU's blow out the hot wind just in direction where the other vents take the outside air to cool the blades. I rotated the PSU vents to blow in one direction with others and it solved some overheat issues. After I sold this unit I am very happy and post my true review. The best thing in it was the cool logo of xbtec company on the upside of miner ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Pity it will newer ROI. Finally another friend of mine has the same device, and he is unable to buy the controller for his unit for several month bcs they don't respond any more to letters. So now he has a bricked unit that hashed not stable for 2-3 month and was bought for 1850 usd. Peeps don't fall for these new made companies and their super-duper solutions - most of them are very close to scammers. Trust only well known world class companies that pay real engineers to construct their mining equipment.

I stupidly bought 2 of these machines earlier this year.
Using Ghash.io pool.
THey will hash for a little while at 3th (ish) but after a random amount of time most of the boards will disappear from the status screen and the overall rate will be in the hundreds of ghs. Reboot and they work again for a while. I contacted them and they said the problem was the controllers and they sent me out two more.
The controllers are block eruptor controllers. BE200 Jet Stratum Miner V 5.47
So they sat in my garage powered down paper weights, Untill i decided to try again. I had thought perhaps its the PSU in the machines, so I have used an IBM bladecenter 2880W PSU. Same results.
Has anybody had any luck with these machines ?
Is it possible to run them from a Raspberry PI instead ? Im guessing this would need some kind of adapter.
I wish id never bought the damn machines and it will be a cold day in hell before I ever use them again.
changing frequency has no effect they will has just as (well?) at 240 or 280mhz.
I have read its possible to upgrade the firmware on the block eruptor controller units ? can anyone point me in the right direction please ?
The machines are a server room with proper aircon. Temp is not an issue.
thanks
