What size are those fans? 60mm?

why small fans? so loud

So how did you get to 3.2 TH/s from 2 Prismas? From your pic you have 16 boards, each Prisma shows up as 8. Right now people are only getting 1440 GH/s per device. So you guys must be overclocking these pretty high.

Cooling and psu it's very important, if you use psu with stable 12v line and heatsink with square around 4000 cm^2 chip works without problem on frequency 270 MHz it's not overclocking. We geting 3.5 thash with same power consumption on 290 MHz when outside was very cold. Maybe prisma couldn't work stable with computer PSU, because after losing on the cables voltage on conectors can be 11.4v - 11.5v it's not important when you use dc\dc, but then we talk about string design it's very important, because voltage separate between chip. Maximal what possible getting from 1 boards around 480 Ghash if use higher voltage.

That is right, when temperature in Shenzhen dropped down o 23 C degrees, we've got better hashrate.
It seems like causality, not just correlation.

We didn't try to use mine on 290Mhz, nice idea. We gonna try today. Thank you for advice ;)

If you went with two (maybe 3) large fans, the failure of ANY of those fans could cause catastrophic overheating as BE200 doesn't have temperature sensors. By having 6, a fan can fail without problem. tldr, redundancy.

quality fans dont crap out in my experience - and the AM Prisma only uses 1 fan itself anyways

I'm giving you the reason the manufacturer chose 6 smaller fans, you can argue it all you want.

And the source of your device is?
The answer is ....
no thanks ;)
but it is translated in English which is a good start
Good luck ...
I like the numbers about rejects expected and real performance  ;D
Are you using consts ;D ;D ;D
and 0 HW error rate also.
By the way what UTI means ;D ;D ;D ;D. something like Utility?

Just be ashamed....Make it open source so we can see what you are actually  using ;D ;D ;D and what constants are inside ;D ;D ;D

Dogie has a valid point with the fan logic. It's not about fan failure rates, its about redundancy and cooling in the event of failure.

Just to clarify, I meant the reason that XBTec told me they went with 6 smaller fans.

This miner is meant for datacenters, not for your room or home office. Same reason full servers are not a nice thing to have sitting in your office, efficiency and airflow is primary, audible noise isn't a concern. These are likely high RPM fans not unlike what you would find in a commercial server. If you are looking for a home miner, this isn't it.

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.

I would hardly say that the typical 15Amp 120v circuit in the USA is a bad circuit.  With the exception of bitcoin miners, I've found few items that trip a typical circuit. 

Items that typically draw a lot are often placed on their own circuit in new construction.  This of course can be a problem sometimes for those with older wired houses that weren't designed to have all the modern draw appliances.

If you know you need a 2500w draw, then you know you need either 2 circuits or 1 220v circuit.....

This just appears to be 4 asic tube miners put together in one box with 2 psu.  Nothing really is achieved other than a nicer form factor.
Remember the asicminer tube was .77 BTC for 1.  So this is four of them or 3.08 BTC + the PSU and the case.  Obviously based on the wiring setup of this, it's not like they created circuit boards or other stuff to handle the mess of PCI-e wires.

So i've racked up that this is worth 3.08 BTC + PSU. Which look oddly the same as the ones in the antminer s4 and the prospero x3 - ie a sunshine (apluspower) ap188.  Plus a metal 3u box. 

The nice form factor is cool and all, but by no means is worth the increase in price.  I doubt the efficiancy is what is claimed vs an asicminer tube - as both produce the same 215gh per board for 280 mhz clock.

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?

The standard residential circuit is 15Amp at 120v.  20Amp @ 120v are used normally when you know there will be higher drawing things.  Then it goes to 30amp 240v, 40, 50amp, 60amp etc.  You can have whatever you want setup.  Most kitchens with an electric stove have a 50amp circuit for it.

In the commercial space, the typical service is a 3phase 208v service.  So 1 leg is 120v and 2 combined is 208v. 

Saying that the USA "has unusually bad circuits" is just ignorant.  There are also plenty of standards in place in the USA that generally prevents single  plug machines from drawing more than 1500watts on a standard outlet. 

The Pacific V3 doesn't need 2500watts through one plug, it  has two power supplies... Plus since it's rack mountable, it's a setup to be placed in a rack with some 208v PDU's.

You're contradicting yourself, but we're also off topic so lets move it somewhere else.

I never argued over the voltages. The standard of cabling along with the design of the grid is sub par in the U.K and AU period!

http://www.emfs.info/sources/distribution/uk/

In the U.S, every household has a split phase 220V service. In older building, typically a 200A minimum. 400A has been the norm for decades. The capacity of not just the standard of cabling but the incoming capacity is far higher. Whilst single outlets (power points) of standard house appliances are 110V, 220V is also common for dryers, hot water heaters, stoves (ranges), welders (garage point), rv's etc etc. With split phase there is NO PME MEN (multiple earth neutral) system ie, floating EMF's affecting both equipment and people alike. Having had to sign safety books when working around equipment that produce stray fields, well, there is a health reason somewhere there.

Point being, a split phase or star phase system is far more efficient, safer and likely healthier than what the U.K and AU offers.

Once again, I'm not sure if you have first hand knowledge of what you've been attempting to educate people with or are simply regurgitating what you've read another misinformed individual post.

This is the hardware subforum of a forum called bitcointalk.org, not "you're all getting mind melded by EM radiation.org". I was referring specifically to BITCOIN MINING, as I said in my last post.

IMHO cables inside it could be arranged more neatly, for better cooling and better look.  ::)

I guess it's prototype on the photo? I don't think it's the same in mass-production...

Case is the same with case on photos.
Cables could be sheafed, but it doesn't necessary really, perhaps for aesthetically beauty only.

maybe good hardware... but this fan make asic miner do a crazy noise!!!

why not a 3 120mm fans???

hum...

with three fans available, i have never read of someone who has had a failure on all 3 simultaneously...

i think it is impossible like mine a btc block in solo!!!

 ;D ;D ;D ;D

thank goodness for ignore! Keep posting reviews for your employers doggie. You need some doggie bags with what you're leaving behind.

3 larger more reliable fans can be far better than 6 smaller less reliable.

first bath of miners has been sent to customers.
Awaiting for reviews

Are you also working for XBTec? You like chinese companies and they like you :)

Any news?

Miners in stock

What news were you looking for?

I also ordered in July and still have not received my asic. Money do not return. The Scam. If I am wrong, then deal with their representatives in Russia. The scam!

How many people have recieved working units from Xbtec?  Just wondering cause hey do seem legit, but only time will tell.

I have ordered and received PACIFIC V3 in Russia. My friend didn't want to wait and wrote a post letter to return his money and got them during a week.

Any pictures?

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

What pool are you on?

Do you have a shop/outlet in Shenzhen or is this an invitation to visit the factory? I'd be interested
in either one.

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:)

Can you provide a screenshot of the stats page and on pool please?

Sorry dude not imeediate answer due to busy days:)
Of course, here are some screenshots - 3 pairs of pics taken at different time

And also one detail: while surfing in this problem solution found on the overclock forum topic started by an employee of xbtec - Betty , announcing about their new product. I wrote in the topic about my troubles and was quite surprised when checked back in few days that the topic was erased and no answer for me.

Hmm ??? :-\

Sorry, nothing I can particularly see wrong to help with. You could try on a different pool [ghash] or with a lower difficulty to see if that smooths anything out.

XBTEC talked about a 280Mhz frequency. I see that yours is at 260 mhz. Coincidence ?

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.

to be sure you won't miss my reply because of a d*** :

XBTEC talked about a 280Mhz frequency and I see 280 Mhz on their screenshots. I see that yours is at 260 mhz. Coincidence ?

My original comment [2 months ago] was in reply to a user saying that 2500W was not possible to run at home. I replied, mentioning that the US isn't the only county in the world and not everyone in the world has 110V 20A [16A] circuits. Ie, plenty of people could still run 2500W at home. I'm also not seeing how you can argue that

110V 20A (16A 24/7) = 1760W isn't worse than
240V 32A (36A 24/7) = 8640W

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.

Just an FYI all homes in the USA are 240V.  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.

If you have a lot of extra time and money advice has addressed this company! ;) ;) ;) ;)

I guarantee you a lot of empty promises to send the goods paid tomorrow and again tomorrow and so 35 days :-\

My first purchase(3.2 th 1850 Usd)  I waited 30 days after payment ,second purchase waited 35 days
had no patience, asked to return money back ;D
And again the same song
Tomorrow we will have done everything tomorrow 45 days

Very unpleasant surprise was the first purchase ......miner that I bought from them was rejected, 1 of 8 cards did not work, I promised to indemnify and cheated......

Attention is scammers - http://www.xbtec.io/products http://www.xbtec.ru/

list of scam
http://ethereum.today/btccloud

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 ;D 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.

This company is a scam. +1

I also tried to contact them but they don't reply.

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

If I remember correctly, these are just Prisma 1.0 boards in a rack-mountable enclosure. If that's the case, you should be able to use a uart adapter and  mine off an rpi. See if there is a version number on the top right of your hashing boards. Should be 1.0,1.1,1.2 or something like that...

thanks for the info ill take a look tomorrow.

on the controller page if i click on test status i see the boards are v1.47 ?

ill look at the physical boards too see what i can see tomorrow.

could you link a uart adapter please ? would be very usefull.


thanks alot for your assistance.

Try google cp2102.

I don't think a standard cp2102 adapter works with prisma boards. I have a few ASICMINER adapters left over, and I think sidehack/novak still have some of their custom made adapters available.

i guess firstly i need to check the boards to see if they do have numbers written on the top right of them, are they any other identifying features i should be looking for ?

ill get the screwdriver out and take some pics of a board later today.

if ,and at this point its a big if,  they are prisma boards how much would you want for a correct adapter ?

thanks

anthony

Ok so here are the pictures,

https://i.imgur.com/itfRNSx.jpg

http://imgur.com/itfRNSx,CVpGvzO#0 (http://imgur.com/itfRNSx,CVpGvzO#0)

so do you guys think i could use an cp2102 adapter and a pi with them or will i need a special adapter ? if so how much and where can i buy one.

were these boards unstable ? having replaced the PSU with a decent one and having them run in an air conditioned room (17oc) they would be very unstable, and require a reboot every couple of hours.

thanks for all the help, would really like to make these damn things work properly. possibly going to look at some submersion cooling too.. IF i can get them running stable.

so have any of you guys got the correct adapters so i connect these boards to a Pi.

How reliable are these boards ? wasnt there a recall due to them not performing well or at my boards at v1.2 a good revision ?

cheers

Looks like a Prisma 1.0 board to me. Send me a PM if you are interested in an adapter.

pm sent ty sir :)
