Proof?

Because you said so I have to believe it?

More likely that the units got fried and these people are responsible and fixing the problem given the report from Toomin.

And you didn't answer the question why the 'retrofit'?

Obviously there were issues.

I'm not sure I can provide you with any proof that would suffice given I can't go back in time and take a picture posing in front of both machines with a time on a card. I never took any pictures while I was there out of respect. I can only show you a picture of the machines they hosted for me running at my 1MW facility still under construction. There are two electric services at my building so while the 1200A 480V service is being built and not currently energized, I have a wimpy 400A 240V service I'm tapping. The picture is a little old one rack has not been hooked up yet but it is now. The S1's in that picture were never hosted by ASICSPACE, that would have been a loss obviously.  It's worth noting my most temperature intolerant miner would be the cointerra, overheating if the room just goes over 80F, and I have logs showing a stable hashrate on it for months while at ASICSPACE.


Re the retrofit it should go without saying; it is not a tier I datacenter and should not be expected to be built as such. I don't think there is a bitcoin mine on the planet over 1MW that doesn't need modifications to airflow after the heat is there. You can use smoke bombs all you want, use some formulas that make you look like math Jesus, and try to predict what will happen before the heat but you never really know until you put it into place. I would be more concerned if they were not constantly looking for ways to improve their airflow.



Hi LordPaco...

Like what you have going on there.  It will be interesting to see what you do when it gets to the point of having to do something to deal with the heat.  Good luck to you, bro!!!

Is it just me, or is this thread shrinking? Could've sworn I saw it at 646 and 645 pages. Now it's at 644.

it is

Someone probably deleted some of their posts on here after the terrible news of SPT no longer selling rigs and mining for themselves.

Pisses me off actually!!!

I think getting a electrician to get you 200A will not be cheap.  And a setting up subpanel for miners adds to cost aswell.

I could be wrong but I just think it's going to be costly to move there and get it all set up.
No, you're definitely not wrong.  Even if we make the broad assumption that everything is already there and setup for you to just populate with the gear, you still need to get the gear there.  Moving across the country is a decent-sized expense on its own.

That's where an 8' x 18' enclosed trailer [sufficient for even hauling a car] comes in very handy if you have one.  I have one to haul my rigs, fans, racks, tools, furniture, etc...
1964  Bitcoin / Mining speculation / Re: antminer s6 4500gh/s 1000watts on: May 01, 2015, 02:13:53 AM
I wish someone would do the math with all costs involved.  To get 28,800 if you are thinking of running at your residence pretty much eliminates renting a house.  That is a lot of electricity and cooling gear to be installed, most landlords would not allow huge modifications for miners.

I would like to see electricity cost, cost of equipment, buying house/renting house, etc, etc.  Finding a place without electricity requirements making it hard.

I just think it will add up quick on costs but I could be wrong.
To get 28.8K you're already well above and beyond a typical home's capacity.  You're talking dedicated circuitry and wiring, upgraded service and new panels.  This is definitely in the realm of commercial at this point.  The data provided by dmwardjr just shows operating costs of a system already in place.

I already have 28,800 watts worth of equipment.  My equipment can easily hash at a 50 TH/s rate without over clocking.  I'm under clocked at the moment.  I'm wanting to invest into another 100 TH/s of S5's with switches, cords, racks, etc...  I'm not saying where this equipment is going.  I don't want anyone to get what I have my eyes on at the moment.  I'm not giving any more details about location or structure.

I've already done the math with several different scenarios.  Sorry, but I don't wish to get into the math on here in this thread.  I have already done a lot of research.  I'm not saying what research, emails and phone calls I have made, but it is definitely worth moving out there if you have enough capital in the beginning to start out with 160 TH/s minimum.  That includes capital for exhaust fan(s), switches, etc...
1966  Bitcoin / Mining speculation / Re: antminer s6 4500gh/s 1000watts on: May 01, 2015, 01:57:41 AM
Even if I were single, I seriously doubt that I would "chase Bitcoin across the USA". There are other ways to make money, and have an interesting life. Having a major part of your livelihood wrapped up in Bitcoin seems like an enormous risk, and not very interesting after 5-8 years, if that long. I can't see Bitcoin as a career at all. Sure there are variety of skills you would develop, none of which require Bitcoin to develop. I would much prefer to develop skills which aren't as likely to go POOF if Bitcoin just turns into a pile of meaningless bits.

I already have skills.  I train telephone technicians for a living for CenturyLink.  I'm a contractor they hire to come in and train their techs.  I have already trained approximately 75% of the techs on the East Coast.  It's time to move to the West Coast very soon to train technicians there.  CenturyLink has a lot of area on the West Coast in Washington State and Oregon.  I'm in Warren, Ohio this very moment in a hotel.  I'm here for four (4) weeks doing 4-Day courses for CenturyLink.  I teach their technicians how to use their meter to identify and locate troubles on wire-line service; not wireless.  The meter they use is the JDSU HST-3000 http://www.jdsu.com/en-us/test-and-measurement/products/a-z-product-list/pages/hst-3000.aspx#.VULeLs40qM4)



Don't assume someone is only mining bitcoin if they move to Washington State.
1967  Bitcoin / Mining speculation / Re: antminer s6 4500gh/s 1000watts on: April 25, 2015, 05:17:49 AM
i do apreciate you preserverance in mining with hardware i mean takes watts in europe i dont know in us but even ten teh investment takes like months to get back and by the btc soo low its can be even more time to get like 1000 dollars i mean a 40Ths might get you 20 dollars per day i dont know if its more but lets like 50 days for roi do say if im wrong

28,800 watts total going 24/7:  This includes exhaust fan, switch, router, 3 other box fans

At 10.6 cents per kWH during the summer:

Cost Per Hour:   $3.052800
Cost Per Day:   $73.267200
Cost Per Week:   $512.870
Cost Per Month:   $2,051.48
Cost Per Year:   $26,669.26

At 12.1 cents per kWH during the summer:

Cost Per Hour:   $3.484800
Cost Per Day:   $83.635200
Cost Per Week:   $585.446
Cost Per Month:   $2,341.79
Cost Per Year:   $30,443.21

I'm under clocked to approximately 40.2 TH/s average:

With difficulty at 47,610,564,513 and BTC price at $228.044:

BTC per hour:               0.01769      $      4.034
BTC per day:                0.4246        $     96.82
BTC per week:              2.972          $   677.70
BTC per month:           12.74           $ 2,905.00

So, [With present price of bitcoin @ $228.044] I would be fortunate to make $560.00 in a month during the summer and $900.00 in a month during the winter.

If I moved to Washington State to 3.4 cents per kWH after all taxes and fees:

Cost Per Hour:   $0.979200
Cost Per Day:   $23.500800
Cost Per Week:   $164.506
Cost Per Month:   $658.02
Cost Per Year:   $8,554.29

That would be approximately $2,250.00 profit in one month at present difficulty and price of BTC.  That's quite a big difference.  That is approximately a 420% increase in profit between there and my present location.
1968  Bitcoin / Mining speculation / Re: Do you think mining will be profitable again ? on: April 25, 2015, 04:52:46 AM
Mining at home is probably still profitable if you mine the right alts and then trade at the right time.

Mining bitcoin will probably never be profitable for most people in developed countries with expensive electricity.

If you live somewhere with ridiculously cheap electricity then maybe for a while yet if you have efficient hardware.

My power rates will go from 10.6 cents per kWH during winter and 12.1 cents per kWH during summer to 3.4 cents per kWH all year round when I move from Alabama to Washington State.  You will be surprised how long one can go with even older hardware in an area with this cheap of power costs.  If the price of bitcoin were to go down significantly, the difficulty would go down significantly.  Why?  Because those who do not have as cheap of electricity will cut off their rigs while those with less than 5 cents per kWH will continue mining.  If you move to an area with less than 5 cents per kWH, you are set!  Plain and simple!  You do need some capital to get started, though.  I recommend going big.  1,000 TH/s should be your minimum goal if you move to a location with less than 5 cents per kWH.

The data I provided above reveals one needed to increase their hash rate 6.08 times what it was a year ago to mine the same amount of coin they mined a year ago [if they actually started a year ago].  That means you needed to increase your hash rate by 608% to mine the same amount of coin you did a year prior.  I see that number going down to 1.5 or 1.2 times (50% to 20%) by November of December of this year.  

My first day of mining was September 22, 2014.  I expect the difficulty by that same time in 2015 to be approximately 54 billion to 58 billion.  Let us use the more conservative 58 billion number.  The difficulty on September 25, 2014 was 34,661,425,924.  If the difficulty on September 25, 2015 is 58 billion, that would be approximately a 1.67 times increase.  Meaning, I would have needed to increase my hash rate by 67% to mine the same amount of coin I mined a year prior when I started.  I started with 10 S3+'s or 4.7 TH/s (over clocked just a hair).  I now have 45 TH/s (under clocked).  I could wind them up to a little over 50 TH/s if I wanted to.  I've increased my hash rate by 1000% or a little over 10 times what I started with.
1969  Bitcoin / Mining speculation / Re: Antminer S6 speculation on: April 24, 2015, 04:46:19 PM
Looks like this thread need to do a 90 day vacation  maybe a 150 day vacation since s-6's will not show up sooner then summertime. Or early fall.

I would agree with it could be a while.  I still think btc being so low has something to do with it, companies have to do R+D smarter not faster.

I think for a little bit our options are S4+ or S5.  Which is a interesting mix.   I was surprised with the 220, I see this as good for future releases showing Bitmain is not scared to go up to 220.

I'm also happy to see Bitmain not being too concerned about telling those who are serious with mining to move to 205 to 240 range.  I do like the capability to still use rigs at 120 during the winter.  This means I can move a rig to a bedroom or living room that needs heat without concern of having a 205 to 240 volt receptacle.

yeah home miners will need to up their game by having 1 or more 240 volt  receptacles.

 I now have a 30 amp and a 20 amp circuit .  These were 120 volt dedicated receptacles for subwoofer amps that I installed in my home 17 years ago.  I now  did a very simple switchover and made them 240 volts.

Of course they are not in the best spots of my home but I will get around that in due time.  For now with the hot weather approaching I will keep mining low.

Sounds like a plan.

I did have six 20 amp/120 volt circuits at one time.  I switched everything over to five 30 amp/240 volt circuits with PDU's.  I doubled my available watts by doing this.  Everyone else should do it as well if possible.

I think I was the one who pointed you in the 240v/PDU direction. Smiley Looks like you took it and RAN LOL. Love your setup.

And I appreciate you doing so, Sir!!!  THUMBS UP!!!

Your assistance and knowledge played a large role in helping me get my setup to where it is at the moment.  Thank you for taking the time to provide mining knowledge!

Kind regards,

David

Glad I could help, especially seeing what your project has evolved into!  Cheesy

Thank you, Sir.

Although, it's kind of a shame it will all be torn down in a few months when I move to Washington State.  It has been quite a learning experience.  This also gave me an opportunity to learn about dealing with the heat, ventilation, networking, etc...  It has been a lot of fun thus far.  I still have a lot to learn.  Especially, when I take this to a much larger scale in Washington State.

I was thinking about moving out to Washington State in June.  I was approximately 80% sure I was moving out there in June due to this Jade Helm 15 thing.  Now, it has reduced to 20% chance of going in June and 80% chance of going between August and October.  I'm about 95% sure I'm moving to Washington State regardless.  It's just a matter of "when."

If you have not heard about "Jade Helm 15," this is the video I recommend you listen to in its entirety:  https://www.youtube.com/watch?v=j4kaNjvRxIw&feature=share
1970  Bitcoin / Mining speculation / Re: Do you think mining will be profitable again ? on: April 24, 2015, 04:20:27 PM
So, looking at both of these examples.  Can you see as each month passes, the amount our hash rate needs to increase from a year prior is decreasing significantly every difficulty change?  This reveals it is probably better to get in now more than any other time in mining PROVIDING one goes big in an area with power costs less than 5 cents per kWH.

Thank you for going into more details.  I was able to understand this version much better.

I agree that now is a interesting time for mining.  We have had low difficulty changes, and even negative changes.  I think it is a good time for miners long term.  It's not a get rich quick, or 90 day ROI anymore.  But still a good time to be a miner if conditions are right.

You are welcome...

You are right!  Providing only the data without much clarification could be seen as "too much" or just "rambling."

Of course, it's still a competition of sorts between us miners and the mining rig manufacturers have that competition as well.  We even have a couple new manufacturers coming into the fray to provide competition among manufacturers.  What the manufacturers create has a profound affect on those who will mine bitcoin.  I'm fairly certain the next generation rigs will create another substantial growth in difficulty.  However, this also depends on supply and demand.  The price of the 3rd generation rigs in relation to bitcoin price can affect demand as well.  I know I don't have to tell you any of this.  I'm only thinking out loud.

You're right; this is not a get rich quick profession.  Unfortunately, 90 days ROI is probably over.  The only ones who stand a chance with ROI in a time frame less than 6 months would be those who have less than 5 cents per kWH power costs.

I also think "new" alt coins [such as SLING] have played a roll with providing a reduction in bitcoin difficulty as of late.  How long this continues is unknown.  I don't mind new coins.  That's better for other miners who choose to continue in bitcoin while others mine alt coin that is also SHA-256.

And absolutely nothing in the photo proves it is your datacenter.  That could be anyones' building anywhere, not even related to bitcoin mining.

And I think your an ass for your assumptions.

I don't have to share any of my math with you. You can believe what you want. In fact it is a very good thing for me that you believe the way you do, so please keep thinking that way. I also hope you continue to spew your vomit because it helps me as well.
Here is a picture of a cropped screenshot of the ebay auction for the transformer on the left in that picture. Try to find a 500KVA 480/208 for that price. You wont.


Here is a picture of about 15% of the shelving we will ultimately need as we build to capacity. Also you can see in the back 3 400A panels uninstalled, a 600A breaker in enclosure.


Here is a older picture of just 150 3KW server power supplies, they sold originally from IBM for $1950 each. I paid on average ~35$ each for them. To the right you can see my crappy asicminer prismas that I bought from a group buy here. There is a reason they are sitting there. You can see a few of my 3 phase 60A IBM PDU's. They will monitor and record a dozen parameters on each outlet and can pull about 20KW each. I bought most of these for $40 each. Good luck finding them now I bought them all out of the market and they are only available for over $300 a piece now and I have 50. They came with 20feet of burly 6awg 4conductor cable hard wired so it saves quite a bit cable cost too. Oh, and it's the shitter on the other side of that wall.


I have good friends and family that help. I won't be putting all that shelving together. For example my brother in law, made this enclosure for my ammeters so I can see amperage on each phase. I will have one of these on each 400A panel, there will be 6 of them.


Sorry ASICSPACE guys for jackin your thread. I'll start my own when I think its time to show people how to build a mine junkyard wars style.

I've been to this facility at least a half dozen times. Not only does it exist but they are a legit operation. I'm sure BTC crashing to where it is now hurts because most of the installation came before this, when the math was better. They are hosting a number of machines for me until I get my own datacenter online which will be very soon now. As far as I know the recent issues was a network error that also propagated to all SP20's to require a reflash on them all. Not a job I would want, especially with an inbox piling up fast with legitimate complaints. I'm sure they could hire a customer service team to handle emergencies but then goes whats left of their profit margin. This is why I am planning on my mine as private, maybe a few larger clients that understand shit happens, especially when you are running the 'budget' type of datacenter. Not to say its 'budget', but face it, it ain't no Microsoft and they arn't charging those prices.

Wither or not you find it profitable to mine or see a possibility of a profit has no bearing on the topic at hand and only serves to troll.

And before I get accused as a shill or fake, here is a picture of my data center under construction. That is two 500KVA 480/208 transformers. Yes there is alot of work to be done.



Good for you, LordPaco!!!

I would personally like to see some more pictures as it progresses, please Sir.  I will be heading out your way from Alabama very soon.  I'm not saying when, but it is soon.  I decided not to spend money on doubling my power at the house since I was planning on moving to Washington State anyway.  My plans were to move there the 3rd or 4th quarter of this year.  I might be moving much sooner now.  I have my reasons that I don't care to mention here.  

I would be starting with only 100 TH/s that I will take there with me in an inclosed trailer.  I was very close to leasing a building in Moses Lake until I found out I would need a minimum of 200kW demand running 24/7 to enjoy a 1.8 cents per kWH + demand charges, taxes and fees.  If one has less than 200kW demand, they will pay double that rate at approximately 3.8 cents per kWH + demand charges, taxes and fees.

I would order another 175 TH/s shortly after I arrive there.  It will take a little time for them to arrive after I order them.  I'm not saying where I will be located yet.  It may be two locations in the beginning (house and a building) until I can earn more $ to increase the power in one of two buildings I'm looking at.  One building in Chelan County and the other in Douglas County.  I'm not giving the city yet.  I'm also familiar with Chelan county PUD's moratorium on more than 1 megawatt at one location as well.  I've been doing my research.

Anyway, back to your place:  I like what you have going there.  It looks like you are looking to get serious like myself.  I'm not doing any hosting.  I will only do private mining for myself as well.  The goal is to have 1,000 TH/s minimum by the time the blocks halve.  We will see how it goes.

Good luck to you in your venture.  Maybe we'll bump into each other some day in the future.  I wish you prosperity and a smooth start in your venture.  And please, keep me posted with some pictures, Sir.

--snip--

A lot of calculations, but keep in mind that the ASIC companies have the first dibs on the newer generation chips. They use them to mine, increase difficulty and then ship. After that huge mining farms, especially in China, mines at a lower cost than the individual.

In the end it doesnt matter what the price or transistor size is, mining will always be unprofitable for the small scale miner.

That post has been posted twice I still have not made it through it all the way.  It's almost unreadable at parts, just to much infomation not enough organization.  I'm sure it took a lot of time though.

And mining is a lot different at this point.  A year ago we were having lots of double digit difficulty changes.  Now it's rare for a double digit change.  There is just a heck of a lot of hash on the network.

I mainly wanted to post the data to prove this point:

The amount we need to increase our hash rate in a year's time to mine the same amount of bitcoin is reducing month after month.  For example:

If we started mining June 29, 2013, the difficulty was 21,335,329.  If we were still mining by Jun 29 2014, the difficulty had risen to 16,818,461,371.  That means the difficulty rose 788.3 times more than what it was a year prior.  [Your hash rate would have to be 788.3 times more than what it was this time last year to mine the same amount of coin.].  Example:  If you had 2 TH/s on June 29, 2013, multiply this by 788.3 to come up with how many TH/s you would need a year later (June 29, 2014) to mine the same amount of coin you mined a year prior = 1,576.6 TH/s.

Let us move forward to Apr. 17, 2014.  The difficulty then was 6,978,842,650.  A year later, on Apr 19, 2015 the difficulty increased to 47,610,564,513.  That means the difficulty rose 6.8 times more than what it was a year prior. [Your hash rate would have to be 6.8 times more than what it was this time a year prior to mine the same amount of coin.]  Example:

If you started out with 2 TH/s on April 17, 2014, your hash rate on April 19, 2015 would have to be 6.8 x 2 = 13.6 TH/s.

So, looking at both of these examples.  Can you see as each month passes, the amount our hash rate needs to increase from a year prior is decreasing significantly every difficulty change?  This reveals it is probably better to get in now more than any other time in mining PROVIDING one goes big in an area with power costs less than 5 cents per kWH.

I can see the difficulty being approximately 68 billion by the first week of December, 2015 with 3rd generation rigs on the market.  The difficulty on December 2, 2014 was 40,007,470,271.  That means the difficulty would have risen 1.699 (1.7) times of what it was a year prior.  This also means if you started with 2 TH/s on December 2, 2014, your hash rate would have to be 2 x 1.7 = 3.4 TH/s to mine the same amount of bitcoin you mined a year prior.

This data was posted to reveal how the race with difficulty to continue mining the same amount of bitcoin is looking better for us each difficulty change.  You do not have to add as many rigs to your present set up to mine the same amount of coin you mined a year prior as each difficulty change occurs every two weeks.  My estimation of the difficulty being 68,000,000,000 in the first week of December is only an educated guess.  I'm not for certain what it will be.  I only posted the data to reveal to miners we do not have to increase our hash rate as much as months prior to mine the same amount of coin we did a year ago.

Well nicehash and westhash are mining a shit coin.  close to 7ph   7ph/338ph = 2%

We need to see how long this event lasts.  3 days would be nice. 1 week would be outstanding.

Frankly this shit coin pulling rate from btc is going to happen again and again and again.

Oh bitmaintech announced a s4+ a very interesting price point and piece of gear. I wonder how long they will keep it around this machine represents the ending of the s-3 chip.  They managed to squeeze it down to .58 watts.  which for the s-3 chip is very good. but it is not as good as an s-5

Yes, I saw that several hours ago.

I worry for Bitmaintech when they come out with this rig several months after the S5.  It's just not good for THEIR business.  They should come out with both of them at the same time.  This way they have a better chance of selling the larger form factor with PSU included.  We may not see the 3rd generation until late August or September I'm afraid.  They will want to squeeze this out as long as possible to sell all of the S4+'s they can.  I believe they had a hard time selling all of batch two of the S4 before coming out with the S5 only a couple of months later.  At least they came out with the large form factor a little earlier than last year.  Maybe they will do better with it.

I have no need for the S4+.  I could use the boards to replace my boards in the older S4 Batch 2.  I would be willing to spend money to replace the boards in all five of my S4's.  They stand a better chance of making more money if they would do this.  I know plenty of miners with S4's who do this.  However, the PSU in the present S4 is the issue preventing them from doing this I'm sure.  Maybe they should sell the PSU with the boards as a possible upgrade kit.

bitmain should send fans of silent to all customers who have purchased s5 with infernal noise

but then again the Chinese by nature and very greedy for money, and with style are born, not made with money lords

No need for prejudice...

Whoa!!!


Just about time that a manufacture released a new product.


This miner is going to be BIG!

Since this uses the same chips as the S3. Can the S3 be downclocked to run at a similar efficiency? 0.58J/GH ?


Also I think this should be put in bold

1. The included PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage.


Pretty much has no market in North America then.


Whaaaaaaaat?  Do you know what a TWO POLL BREAKER IS?  220 to 240 volts, depending on your configuration.
