Thanks Rich.  I should have took a look for myself at their website.  However, I really don't care for SPT anymore unless they change their ways.

There were rumor of them coming up with a smaller unit, but yeah this is insane. This is basically a small furnace. I guess its efficient in space management, but thats probably not what i would want to setup in a warehouse dedicated to ASIC mining either.
1842  Bitcoin / Hardware / Re: Bitmain S7 + 1300W Power Supply? on: December 18, 2015, 02:56:14 AM
So I know all the reasons why this isn't a recommended combo but what I'm curious is, has anyone done it?

Searched around and can't find anyone that indicates they have done it.

I'm not planning on doing it but this was curious if anyone had done it and posted or shared their results somewhere.



People do it and it work just fine, but it need to be a good PSU. Personally i'd go with the EVGA G2 1300w, it should handle all the way to 1440W at the wall for a 12/15A 120V breaker limit.

With a 10 years warranty, this one is a no brainer imo. Other high quality PSU like made by Seasonic OEM or SuperFlower works too. That include some of the corsairs.

Yeah that's what got me thinking, I have a brand new EVGA 1300w sitting around waiting for my S5's to show up and the S7 just showed up today but I don't have 208V at home to run it with the 2880W PS I have for it

You're fine then. Its rated and competent for 1300w DC thats fine for 1440W at the wall load. Just keep in mind you lose 1-2% efficiency when you do it, but thats pretty much the one downside.

You might need high quality splitter or good dual cables to plug the 10 pci-e tho.

Also a 1300w for a single S5 is pretty overkill, i'd run two overclocked ones on that. At 393hz that would be about 1280W at the wall, 1162W feed, so 90% load~.

Thanks for replying guys. I see there isnansection here where forum users offer services and tech for coin. I think I need to buy something or I will spend it all on papa johns Smiley)

Yes;
https://bitcointalk.org/index.php?board=5.0

The marketplace has the Computer Hardware subsection which is computer stuff AND ASIC. It also has digital goods sub board. And then there's the services, services announcement and services discussion right there as well.

Remember to use Escrow.


I guess it's my luck to blame, I just sealed the deal with this guy from this forum for an iMac. Sent him the money and now I saw everyone is talking about escrow. I'm feeling kind of lame:((

Well i hope its a very well established, active and trusted member, because people make new accounts just to scam people every minute of every hour of everyday. There's a board filled to the brim with scam accusation and thats just the one that get reported.

Hi guys, I'm new here and I just started reading the forum. I see a lot of advise like "invest Bitcoin", buy mining equipment etc. But I don't see anyone talk about daily life products. Food, computers, bills, Christmas shopping. The other day I was paid 4000 usd in btc and now don't know how to spend it wisely. But I ordered a pizza today and it tasted good.

I'd get some miners, because you gotta invest money to make money. Then it depend on what you want to buy, you can buy pretty much anything with Bitcoin. There are websites like Newegg and Overstock that sell tons of stuff, and between a BTC debit card and all the online retailers, you can get pretty much anything that is not cash only.

However, as I mentioned before, I will be doing a 'ckpool' restart shortly.
That will happen in 5 minutes.
Done.

Tubes aren't getting work since exactly that time where you said "Done".

Looking nice so far, trying to do the switch from M's Miner Monitor.

Is there a particular reason BitcoinCZ is not in the pool thing? Not sure what that feature even do, but i was wondering if they did not have the API or something!

They're also known as Slush pool. We'll rename it in a future update.

I'm aware of Slush's pool which is not in the list, which is why i am asking. Maybe i did not get the latest version branch when i downloaded from the website?

Oh, yes, very possible. Check to see if updates are available in Settings and change to Nightly or Beta (I think it was promoted to beta).

Beta indeed has it, i see there is also CKPool with support for its api. Does that include or will you add Support for Kano CKPool? I'm guessing its mostly the same backend/api, so adding it should be mostly copypaste if its not interchangeable already?
1849  Bitcoin / Mining speculation / Re: Setting up new diff thread Dec 6 to Dec 20 picks closed. on: December 17, 2015, 05:53:04 PM
with that diff, the s7 is losing 1/10 of its haspower
well, to be fair... *everything* is losing a relative share of the aggregate hashpower, not just the S7s.

(Over 2 months)

No real need to complain, so far the BTC price has more than kept up with the difficulty raise. After the next diff increase in 1~ day, the difficulty will have raised by 50% for a 35%~ loss in BTC income.

However the value of BTC has literally doubled (from 220$ usd~ to 440$~ usd), so anyone who were planning to ROI their miners when calculated at 220$ made bank by now.
1850  Bitcoin / Mining speculation / Re: Best Mining Hardware on: December 17, 2015, 09:35:45 AM
If I told you I could get pretty much  free electricity (works out like 2-3 usd per month for one of the miners), I would manually set up the machines would anyone be interested in bulk buying with me to save cost all around? I can host the farm, provide the electricity for set price of 3 usd per month. all you would have to do is buy the rigs (I will pay equally for them also) and provide technical support. As you can see I sell physical bitcoins so I guess that shows I am trustworthy. I can disclose my full identity and contact address naturally.

Anyway if anyone wants to get involved great. I can probably afford 2 S7 miners at full price so if we get a few more people we could do it that way pending how many we have to buy to get a group discount..

Or I will try 1 or 2 by myself and see how it goes Smiley


This can probably get you right to the point;
https://bitcointalk.org/index.php?board=137.0

Its the sub board for dealing specifically with group buys. Just be careful because if you aren't here to scam people, some others, however may very well be here to scam you. So be really, really careful.
1851  Bitcoin / Mining speculation / Re: Are we all going to power consumption hell? on: December 17, 2015, 07:11:30 AM
So yea... OMG we use a lot of energy for this funny math. Can I repent somewhere?

Some places have extra that is not being used... so you might be doing the power company a favor.  All depends on where you live.

Some commercial on here you see setting up close to electricity centers with extra (one was hydro).  It works out good for all. 

Its not too bad, certain type of gaz we emit, like the A/C gaz multiply the heating effect by thousands vs its watt consumption. So in term of mining heat generated, its pretty ecological in comparison.

If you use A/C for your stuff though, you're going to ecological hell xD
1852  Bitcoin / Mining speculation / Re: antminer s6 4500gh/s 1000watts on: December 17, 2015, 07:00:36 AM
We may very well see an S8 around February with 2 x 1600W PSU's at 10+ TH/s and the same size form factor as the S4 and S4+.  However, that may not be feasible by requiring a 240 Volt outlet.  It would be strictly for data centers or those with 240 volt outlets.

I think they have hit the 'average user' power usage wall. x2 1600W is like running an oven at 400 24/7! Look at the SP50, x10 1600w PSUs... jeez.



I'm not even sure thats convenient for a datacenter setup. What then? They're going to start expecting people to use 550volts? Can you even run any kind of PSU at 550Volts? Geez.

The S2/S4 format make much more sense for datacenter. And for home, the SP20/Avalon4&6 format make the most sense

No, it would run off of one 30A/240V outlet with PDU or whip.  One 20A/240V double pole outlet will suffice for one rig.

EDIT:  30A x 240V = 7,200 WATTS  or 20A x 240V = 4,800 WATTS

However, I'm not so sure of my thoughts anymore.  I could see them doing something TOTALLY NEW with the 1600W PSU but having larger blades with 50% more strings on each blade than what they have now on the batch 1 though 9 S7's.  I can see it smaller than the S2 and S4 form factor and about the same size as the S5+ form factor but inside of an enclosure with 4 x fans.

But the SP50 is 16,570 W, its not 4800watts. I think i/we confused which miners we were talking about.

So i meant, with the SP50 that you need 10 1600w PSU. I dont think that's convenient for anyone.
1853  Bitcoin / Mining speculation / Re: New startup with 250k, what should I invest in? on: December 17, 2015, 06:49:02 AM
Depends on your electricity rate, if you already have a datacenter-like setup to place the miners in, etc. Maybe give us more details on your situation?

You can't buy knowledge. Spend a few dozen hours educating yourself before you proceed with your venture.

I'd sell my knowledge Tongue Consultants and specialists get paid for it all the time. Of course, this is a lot of money to entrust into some dude on the internet.

Trust me it never works out.  I have had 3-4 of these start ups that come to me though PM and ask about a start-up and want info.  Almost all it is not cash they have but cash they are asking if they had.

The first one I thought what do I have to lose? Anwser is time... so many questions and in the end no pay as it stay's in planning.   The other ones I have gauged seriousness and they just were not even up to par.

I suggest anyone thinking this is a great idea to advise... skip it unless they are paying up front.   And honestly it's better they research it on their on as they will learn so much more then giving certain answers.  Being a knowledgeable investor is important

Fair enough, back to replying to forum to these questions as time allow. I do have people that PM me often and ask me tons of question. I do reply and i don't mind too much because of my free time but yeah. I don't really get anything tangible out of it.
1854  Bitcoin / Mining speculation / Re: Best Mining Hardware on: December 17, 2015, 06:46:15 AM
just a question the big mining farms are making millions. Why is that so when small farms struggle to break even?


Also bno body answered yet. Can I connect remotely from another country?

You could add a Rasberry pi to the mix and monitor it from anywhere, even power on and off I believe.

http://getminera.com

Also someone mentioned the noise. S7's are LOUD. I brought one home to test and I could hear it from anywhere in the
house.  Comparable to a hair dryer on high... constantly running. But more watts lol.


The big farms have big starting capital and they get good deal on electricity. Like electricity here is 0.06 residential, but big industrial setup gets 0.03$/kWh (+10$/month per kW)

They get prices on the miners in bulk, its much cheaper, they get better prices on everything, so they make better profit.

At home you can easily make money too, you just need good electricity price.

You really need to check out what user CHAOSiTEC did in this thread https://bitcointalk.org/index.php?topic=526060.400

That is a great link, thank you. I am going through it, a lot of posts. For one i tried a value for 200/60, and i get 12gh. Well still not quite there yet, but its better than 0, in the right direction.

The other thing is i'm not downvolted as much as them so i'm not sure how that affect the required configuration. But i'm working on it.

Also the turnpot resistor is dope.
Thought it would help Wink

Yeah, the resistor is pretty freaking cool.

Yeah it did, i did not find the solution there but it helped figure that the problem was the chip timeout, not the freq value. I did not find the freq values i wanted but i got 193hz which is close enough.

Doing 100GH ish for 110 watts ish. Close enough to what i needed.

Thanks.

I have s7 and s5 miners ...thanks
Pretty sure Kano will handle your hardware with stock firmware.
S7's working top notch.
Pool won't slam your rigs around.

This remind me. The AsicMiner tube don't work with most pools, they will crash and trash and complain. Honestly its a pain. I found out that they work fine on GHash.io, but i did not try on here.

Would anyone know if Kano.is handle AsicMiner Tube/Prisma as well as Ghash? (Without causing them to crash)


Take a look ath this post from Kano...

https://bitcointalk.org/index.php?topic=789369.msg13252062#msg13252062

Thank you, i dont read for a few days and boom. Funny this happened 2 days ago.

At first it did not work, when i put a Virosa.workername. It would submit share but they were not being credited to my account. Then i removed the .workername and it works.
I'll let these run and report if it works or if it still crashes.

Thanks Kano and thanks -ck for coding it in. Smiley
1857  Bitcoin / Mining support / Re: Mining Home Network security issues on: December 17, 2015, 04:54:25 AM
Thanks guys, starting my rig after Christmas! Btw, the S5 would go in my furnace room and no one sleeps in the basement so it shouldn't be a big deal. Appreciate the help guys.

I doubt 1 S5 will make a huge difference, they do run hot and loud.  It's just their nature.   But if you grow I'm not sure if furnace room is greatest of room's.

Depends on how well it's insulated  i guess.  But normally with gear you keep it far away from sources of heat.  But again since talking 1.. can get away with it most likely.

Guess it depend how much air the furnace room move. If its stale, it would be very bad for miners.

Just a handful of S4 is like having a couples of oven turned on 24/7 with their oven door opened.

Very true it would depend I'm just basing it off my furnace room.  (I have never ran miners in it).  But if his has bad isulation and get's hot... yes it is not good.

But hes also using only one miner so not thousands of watts.  A handful of S4's is a lot more watts then 1 S5.   So had to tell.  But my first choice would not be a furnace room either.

Ok so where would be the best place to put one. I live in S MN, so it gets pretty cold in the winter. Would a garage or shed with power and internet work?


Yes, depending on how much hardware you put in there. A miner or two, no problem. If you put more, it does not matter if its summer or winter, you will need airflow into and out of whatever room you put it in.

If you took the output of the miner and put it in your heating vents, you could heat your place with your miner's exhaust. In this case it would be okay to have them in the furnace room.

But if the heat is dumped in the same room as the miner, its not going to work for very long.
