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!!!

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.

why small fans? so loud


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

why not a 3 120mm fans???

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.

hum...

Hi community,

Newest bitcoin miner block erupter has been outputted these days.

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

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.

blah blah blah

Are you.... are you honestly trying to argue that the USA's for bitcoin mining?

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.

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?

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.

The standard residential circuit is 15Amp [12A 24/7] at 120v.  .... Saying that the USA "has unusually bad circuits" is just ignorant. 

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

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.

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.

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.....

why small fans? so loud

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.

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.

no thanks Wink
but it is translated in English which is a good start
Good luck ...
I like the numbers about rejects expected and real performance  Grin
Are you using consts Grin Grin Grin
and 0 HW error rate also.
By the way what UTI means Grin Grin Grin Grin. something like Utility?

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