I got .039 btc for nice hash...now the expected payout says .046 lol i hope i get that  Yeah it moves around a bit. Multipool seems to struggle. A while back Multipool and bitminter thread were arguing that multipool's software under preforms. Multipool left in a huff. I gave multipool 1 day here and they did badly. I am not dissing multipool, but for my scrypt I will use nicehash. https://www.nicehash.com/they predict .9723 -1.1795 btc for a gh of scrypt right now that is about a 1.075 btc payout for 1000 mh. I have 31 mh so 31/1000 x 1.075 = .033325 btc for me for you 52/1000 x 1.075 = .0559 btc but that is now if they slow on blocks it drops. So far they are having a good day today. Ya I think I'll stay on nice hash...might even move over my other 80mh/s too yeah I have 14 in house gridseeds I may move them from wemineltc.com to nicehash |

rates are drifting up. more s-3's are shipping. maybe some sp30's https://bitcoinwisdom.com/bitcoin/difficulty ----------- 19,670 http://bitcoincharts.com/ --------------------------------- 19,101 total ---------------------------------------------------------- 38,771 Avg ------------------------------------------------------------ 19,385.5 current rate ------------------------------------------------- 18,736 so 18,736 to 19,385.5 = 3.46 percent jump with about 1311 blocks to go |

since there are so many miners here and I want to buy ANTMINER S3 I'll post my question here. Is there a chart of multipool mining profitability in fiat over a long period of time (6-12months)? If not maybe you can tell me from your experience.. I want to know whether the current $1.6/100GH/day is somewhat stable and can be expected to stay that way the coming 6 months. (I'm a newbie regarding mining, so with this miner I can use it for multipools right?  ) I'd take some serious time learning more about bitcoin before you invest a cent. The difficulty changes after every 2016 blocks. Here is a list of the historical increases. https://bitcoinwisdom.com/bitcoin/difficultyIn the last 6 months it has gone from ~3 million to ~19 million. SO NO WAY you will be making anything close to $1.6/100GH/day in 6 months. thanks! I know about bitcoin difficulty and got burned already I'm asking about the other coins since multipools mine the most profitable, which ever coin it happens to be. But there is no "profitability" chart of multipools over such a period of time. clock www.nicehash.comyou can study them and may be able to figure out if they are better for you then straight btc. |

Lee have you billed for the july 20th host fees?
I have not seen an email or read that the bill was sent.
This 30 day period had no down time. I have 1 dragon miner. So it would be 180? or 185?
Thanks phil

My miner has passed the export scan. Yessssssssss....
I know someone mentioned about the FANS, question: What is the RPM of this fan in the unit? From researching this before, they do sell higher RPM fans, like 2000+ RPM vs. 1200 RPM fans of the same size and the same voltage. Do these fans have the typical 2-3 pin plug, or would there be soldering involved? If its not obvious, the higher RPM we can make through that tunnel, the faster the chips would cool.
I have some very fast delta fans loud as fuck 3 pin but they move 35cfm more then these fans move. My 2 pieces are coming soon as they are marked shipped. I will run 1 s-3 with the faster fans for 1 day then flip flop it to the other s-3. See what happens. BTW these are 4 pin plugs. My deltas are 3 pin but I have a killer fan speed controller so it is not an issue. |

Does anyone have an idea what can lead to this hashrate?  All chips seem to be fine. It is powered by a 1600W PSU (all 4 PCIe Cables connected), but it is only ~half of the promised hashrate. Latest firmware is also installed... Kind regards what does your pool say you are mining at? I have had bizzare reading in the gui that do not match my pool's numbers. In the end the pool pays you not the gui . is cex.io reading 250gh? |

Assuming $0.06 KW/h for electricity and free cooling, what would be considered the best investment in mining hardware?
New ASICs, or older less efficient hardware that might be able to be found cheaper (considering that it would still be profitable with overhead costs this low)?
I have been doing some math and it almost seems like a large quantities of Antminer S1's might be the best total hashrate / $ choice?
What are everyone's thoughts?
Depends just how much of the above you have. Probably always 1 step behind what is considered viable as the $/GH will be so low. S1s are slightly too early for that, but will be perfect in about 6 weeks and perfect to buy today. I have a lot of power. A 3-phase 200 amp panel, so potentially up to about 44 30-amp 240V circuits or over a hundred 20-amp 120V ones. The cooling uses passive environmental cooling, so I need to decide on the hardware and get it ordered as it will likely only be able to operate from September -> May, then possibly be turned off for the summer. I would like to buy up as much older equipment that other people cannot run profitably and run with it for the entire period and then likely shut it all off come spring. I'm sorry, what did you mean that it's slightly too early for S1's (but perfect to buy today? - and what would be a good price for a larger quantity of S1's? (say, 100-200 of them if I can find someone selling that many)? threads for prices: https://bitcointalk.org/index.php?topic=715682.msg8084229#msg8084229https://bitcointalk.org/index.php?topic=716458.0https://bitcointalk.org/index.php?topic=675598.0 |

Thanks for the thread. I bought a Falcon today during the sale. Wanted the War Machine and had it in my cart but when I went to complete it, they were sold out.  Sold my 2 Blades on Ebay which actually paid for the Falcon, so definitely happy with going from 11mh to 27mh and not costing me anything. Just posted new numbers https://bitcointalk.org/index.php?topic=698679.msg7923839#msg7923839I earned .0352 btc for all 3 pieces of gear last night |

my chance of solving a block with 15gh is one in 62000 if I mine an entire day .
I do not believe I will ever win a block. with 15gh.
my cost for that 1/62000 chance is .0004026 btc . this is what those 15gh earn when they mine in a pool.
that is .23 cents so for .23 cents I can win about 14000 dollars.
now I mine in a pool the other 6 days. I earn 6 x .23 cents = 1.38 in the week or 5.25 a week
power cost to mine is 3.30 a month. so right now this setup is making 2 dollars a month profit.
the sticks have roi'd. so that cost is 0. I run the router and switches for other mining .
I use a mac mini to do this and that runs 24/7/365 for other work. So my results are 2 dollar a month profit and 4 or 5 days where I can win a block outright.
solo mining works for every one if they are making a profit with pool mining. just need to figure how often to solo mine
this is why no major pool wants the secret to get out as it will hurt them. Most people just don't get the math of this and mine in pools.
you need to solo mine with gear that turns a profit for a small part of the time.
deciding what percent is important.

I wanted to post my thanks for this. I have 2xS1 that I may have gone a little heavy on the pencil, as they wouldn't mine stably @275mhz. I even checked the voltage and they were all spot on .84v to .86v. However, I clocked them on down to 250Mhz and they hash great @130GH. And on a gold rated PSU the two combined are only pulling 303W @ the wall. So, I'm considering 1.16 W/GH a success!
Thanks again!
heck that is better then my freq 275 hash 140gh and 187 watts |

variance!! do I win a prize? Ah... regarding this hearsay about a large hasher withholding blocks, I was not aware of that but as I said at the beginning of this thread I was starting to wonder if it was something like that going on. Don't get me wrong, I love the pool's site, best interface around and very clear, plus the operators at least appear to be very transparent. It was just that terrible luck they had a few days ago that left me thinking WTF?? Well the pool was running close to 105.9% luck if I recall for their 3 month average before the sh*t hit the fan in May (when the withholding attack started supposedly). At that time nobody complained that the pool might be cheating, although people did allege that in the past back in 2011. So when it's up almost 7% (106-99) nobody complains. When it's down 7% something is wrong. The withholding attack is not hearsay BTW, the person was identified. But he states his custom version of CGMiner was at fault. The thing is it could have happened at any pool, and some pools don't even bother with the nice stats. Too bad the withholding didn't go on at ghash.io lol. The same "attack" also occurred on Eligius and the guy is asking for payment which Eligius held once they discovered the problem. You can check the pools subforum for this info. Eleuthria might not be eligible for sainthood but he's one of the best pool ops around. The problem with the withholding event is very simple it now is true it can be done. If anyone with a copy of that custom cgminer wants to attack any pool and make it hard to detect they can. Since cex.io is so big they have the ability to toss 2ph to 4ph in the shitter on any pool they want. the only defense for a with holding attack is solo mining. |

A £5 note is worthless if there is no gold behind it for example.
With no guarantees it collapsed, as people realised the IOU's ( the sub-prime mortgages ) were not worth a penny; wiping out several banks and stock exchanges.
The equation controls the amount of coin out there. That's clever I have to say. No need for a central authority if it's all built in.
The general concept is right, but when the govt repealed the gold standard, its no longer backed by gold (implicitly). What it is backed by is its ability to pay taxes, and the government's subsequent ability to enforce the law. guys with guns. that say they are the law. now some countries are worse then others but it boils down to the ability to hurt you if you don't pay the tax man. |

so 4500gh at 3000 watts
okay that is .666 watts a hash .
my s-3's do 430 gh at 328 watts that is .763 watts a hash.
lets see some paid 4500 usd some paid 5000 usd.
for 4570 usd I get 7.8 btc that is 12 s-3's .
I need 4 psu's to run 12 s-3's
4 evga's 1300 = 680
so I need 5250 usd for 12 x 440 gh = 5280 gh and 3936 watts - s-3's
5000 usd for 1x 4.5th and and 3000 watts = s-3
while it is sad that the sp30 is short. it is close to equal to buying s-3.s .
maybe just a bit better if you paid 4500 and get the sp30 before the 2nd of aug.

For those of us that are wanting to reuse CX-750M's - You can run easily run 3 _blades_ per CX-750m.
Batch 3 running for 24 hours stable with 4 S3's on three cx-750m. Reading 190watts per blade at the PDU.
Measured at the pool, ambient is 85* F.
428 @ 42C
441 @ 42C
440 @ 42C
453 @ 43C (oc'd to 225)
Bitmain says "Don’t parallel connected different DC input from different PSU into the same Hashing board." Do you read that to mean only use one PSU per blade or one PSU per miner? easy 1 psu per blade. = good 2 psu on the same blade = poof magic smoke. Here is why: a blade does allow pcie power to pass . Pcie plug-----Blade----PCie plug so 2 pcie plugs on one blade fully mix. they must be from the same psuTHE controller does not allow full current of 12 volts 30 amps to pass from blade to blade BLADE-------Controller -------BLADE So 2 psus are kept apart from each other by the controller. |

remember to trust no one. do not send money first. use escrow.
yeah his advice is important. make sure you will get the gear. and if the psu is good the price works. |
|
|
|
|
with free power they could be okay. I have seen lower prices. if you have a decent psu (at no cost)
they would earn back close to 1 btc that is about 590 usd. at the current price take off the 350 you paid you could make about 200-250 bucks by the end of winter.

Why is everyone still beating this dead horse.? It's been pretty well established that "HEAT" is NOT the cause of the S3 problems, it poor design and possible sub-par components.
We've already read that some users have put their S3's in front of A/C units and experienced no improvement.
Now we have pages of people trying to put heatsinks on chips that dont need them.
Lets face it , Bitmains first performance figures were "optimistic" and probably thrown out there in a hurry to get the machine to market, and after further testing they realized that they made a mistake.
That's why they gave us money back, not enough but a good gesture, not many companies these days would do that.
If we are into Batch 4 and possibly batch 5 with no hardware changes then I think you can safely assume that it is what it is and probably cannot be fixed.
If there was a fix to be made, I think Bitmain would have done it .
This is not a problem that firmware up grades will fix either.
JMHO

I tend to agree with you. I believe the stock setting should be 212.5 with 430gh and 328 watts on a gold psu. They now sell them at 218 with 441gh and 340 watts on a gold psu. >>>>>>>>> I feel this is not stock but a small overclock. The real mystery is the s-3's that do 480gh or 500gh and freq 237 or freq 250. |

Ok first let me say I got my refund yesterday when the last units I purchased arrived at my home.
For a bitcoin hardware company bitmain seems to be exceptional in sending equipment when they said they would ship it and at a fair price. Kudos.
Currently the hardware is performing as shown below as per the accepted shares at ELIGIUS:
All are economode 218mhz and only one (ant3 has one x and one -)
all 7 have a 12 hour average of 411GH
ant1
12 Hours 440.52 Gh/s 4430848
3 Hours 446.52 Gh/s 1122816
22.5 Minutes 427.59 Gh/s 134400
ant2
12 Hours 394.45 Gh/s 3967488
3 Hours 386.10 Gh/s 970880
22.5 Minutes 399.08 Gh/s 125440
ant4
12 Hours 434.04 Gh/s 4365696
3 Hours 425.86 Gh/s 1070848
22.5 Minutes 417.00 Gh/s 131072
ant3 (asics have one x and one -)
12 Hours 383.19 Gh/s 3854208
3 Hours 386.20 Gh/s 971136
22.5 Minutes 364.06 Gh/s 114432
ant5
12 Hours 376.09 Gh/s 3782784
3 Hours 371.80 Gh/s 934912
22.5 Minutes 378.31 Gh/s 118912
ant6
12 Hours 409.90 Gh/s 4122880
3 Hours 408.14 Gh/s 1026304
22.5 Minutes 406.41 Gh/s 127744
ant7
12 Hours 444.21 Gh/s 4467968
3 Hours 457.21 Gh/s 1149696
22.5 Minutes 482.97 Gh/s 151808
set the low ones to 212.5 that would be number 3 and number 5 |
