Thank you for that!

if we put in a dryer outlet, what cord would we need to convert from a dryer outlet to connect to the unit?



Tell him to put in an L6-30R

^This results in needing a $25-40 specialty outlet, in addition to a $50-200 PDU, plus the PSU cables. good if you want a big clean setup, not for a budget or if you only need 1-2 power cables.

if you want to go on a budget there are cheaper options for delivering 220V, such as a common 220V european outlet ($5-10) and a matching PSU cable ($5-10). might require shipping from overseas though, but youll save at least $100

Had anyone troubles with mining with s7 on f2 pool.?
Looks like their hash rate is not stable and gives out 2-3 TH on 80% of observed units (b7).
Only few from 10 work as promised.
But When working on antpool they all hash 4,8 TH.

I guess the question is why would you be mining on F2 and Ant? Supporting the Chinese that don't care about the future of BTC and already own more then 70% of the world hash. So many better pools to pick from.

 Most big pool miners do not want the variance risk.  On smaller pools.  Sad as they cause the problem and do not realize it.
I support a lot of small pools and  when I look at the math of :

https://bitcointalksearch.org/topic/kanopool-kanois-lowest-09-fee-since-2014-worldwide-2432-blocks-789369 just up to 12ph
https://www.kano.is/

stratum+tcp://mmpool.org:3333


https://bitcointalksearch.org/topic/150th-pplns-05-jonnys-mining-emporium-bravo-miningcom-1330452  stays under 1ph most of the time
http://www.bravo-mining.com/
stratum.bravo-mining.com:3333


all pay better then antpool or f2pool.  but not enough people mine  at them.

They simply do not understand math .

Sounds hard core but it is true.

Now I have 1 s-7  it mines at f2pool inside of my friends old bank.  He still leases 1 floor and I am teaching the game to him in case he decides to   go large in Washington state with a few investors.  Maybe 10ph in gear.  I know they won't want to go to a smaller pool as they do not want variance. So I am showing him why I would use a pool like Kano's  for now we are pointing where he wants which is f2pool.

   I hope to get him to move it to kano.is this thursday.


Very true and sad, on a daily basis yes the variance is higher but over 15-30 days not so much, if you are running 10PH or more, then every point matters and getting PPS less 4% sucks, just to get the same payout daily? Over 30 days you would be 101% or more on Kano. If these big guys were on Kano for the last 70 weeks, they would be at 103.9%. For every 10+PH miner that moves to Kano or other small pool, the variance reduces. F2 and Ant can't come close to block change times and thats an advantage Kano and Solo have over all others.

with all due respect, it is nothing that it s a guarantee of some sort that you will score above or even 100% at that pool going forward.
In fact, if it was above 100% for a while, one would think that at some point it will be below 100% for a while as well.
Of course, with a higher hashing in the pool, variance will decrease.

Here, have a read of this:
https://en.wikipedia.org/wiki/Gambler's_fallacy#An_example:_coin-tossing
BUT most importantly, look at the image on the right and the description.

Luck DOES NOT correct itself.

Expectation is always 100%

... not 50% coz we got a 150%, not 3 reds in a row coz we got 3 greens, not any other random thing someone thinks up.
That is all Gamber's Fallacy, it's not "some better theory", it's Gambler's Fallacy.

The reason why luck tends towards 100% is not a correction on what happened before, it's that you always expect 100%

If you have have 200% luck since a pool started for 100 blocks (yeah that'd be pretty lucky) you still expect to get 100% for future blocks.
So, since maths goes on forever and an eternity, the average of 100 x 200% + 1,000,000 x expected 100% moves closer to 100%
That expectation is to approach 100%, in this case from above, but it's not correcting history, it's simply expecting to average closer to 100%

let me also add, Kano's fee is .9% and yes Ant says zero fee but they DO NOT PAY transactions and Kano does. Most blocks now include .25 to .50 in fees and after Kano's .9 most of the time 25+ BTC get distributed to miners unlike Ant which is alway 25.

Where exactly did I say that there is a guarantee that it will happen IMMEDIATELY-this is gamblers fallacy.
The expectation that over long time periods luck shall not exceed 100% is reasonable and has nothing to do with such fallacy.
To give you an equally simple example: In ideal situation toss the coin 5 times and all five come as heads does not mean that I have higher chances to have tails next time, but if I toss the coin 1 billion times, it should be close to 1:1. In addition, it is possible to calculate the chance of tossing 30 heads in a row, which would be ~1 chance in a billion. Similarly, it is possible to calculate how likely is 103% pool luck to continue for a year, or ten. Check with organofcorti for exact numbers.
On the other hand, over a long period of time, luck is likely not to exceed 100%, and in fact slightly lower due to orphan blocks (analogy with many coin tosses result in 1:1), therefore there will be periods with less than 100% luck simply due to variance. When-unknown.


That is 100% correct, did not mean to imply that your comment is based on Gamblers Fallacy, I was just posting a few comments that Kano pointed out and agree that long term it will always be 100%, but Kano has 2 orphans in last year compared to the big pools that have a much higher percentage and I was also stating that a large pool with zero fee is not any better then .9 fee but pays transactions to miners.

Sorry for any confusion.

Here are the stats:

clip stats

Here are the stats.  Bitminter comes in close, but the fees will get you there.

Thanks for the past stats, it is interesting, but what exactly it says going forward-absolutely NOTHING.

Not really my business, but why all this buying and selling on a hardware forum?
btctalk has Marketplace.

Amen - Between the buying, selling, and pushing everyone's favorite pools this thread is covered in junk.

Back on topic!







Maybe we can hire a mod to stop in here for a week and clean up the last 100 pages or so. I'd wager only 10-12 of them are relevant or worth keeping.

Let me know how this works out as I've been getting a lot of message offering to sell me S7 but for whatever reasons, they're not willing to use escrow thru Ognasty or Phillip and insist on using ltc as escrow which I'm not familiar or comfortable with.  Glad Phillip is able to help on this transaction.

Yea, no response since I insisted on escrow. I think the account is hacked and @luckypyrate does not know about it. The below is what I sent him via PM after a few PM exchanges. I also chatted with him on Skype little and he sent over the below pictures of the miner, looks like images off the net.

http://prntscr.com/9ryvpy
http://prntscr.com/9ryx5s

"Sorry, will have to wait for some verification that you are really luckypyrate. You profile shows local time is 5 hours ahead of EST, your profile also shows password recently changed and you mentioned the miner was was 15km away. You would be stating miles, not km and how can your local time be 5 hours ahead of EST if your in New Orleans? Things don't add up here, so I will reach out to other who have done transactions with you to see if they have your email address or contact info. Also, your profile does not show a BTC address and your email is hidden. To may things are off here for me to blindly send coin without some due diligence. I'll be in touch tomorrow."

Electrical engineer. Mining since 2014.
I have an electrician here right now who has come to wire a 220v line for me. I am intending to use the PSU from Bitmain.

Can anyone tell us if the PSU comes with a power cord to plug into the outlet?

I am in the US and we don't know what sort of socket to install. Is it like for a US dryer?
PSU comes with no cable.
PSU has C13 female connector. https://en.wikipedia.org/wiki/IEC_60320#C13


NEMA outlet socket depends on what kind of total setup you are having, what size of breaker, wiring etc. Your electrician should know more about these things.

Yeah he says anything over $2500 requires this and I can just reference my PWDBW # going forward.  I did ask him if they used my HST code and that there's no Custom tax.  He said no custom tax.  Hopefully no fees as well.  Getting ready to go to the bank to pay for 6 more right now.

Evil beware: We have waffles!
Got a call from FEDEX asking for my email as the order is over $2500 so they will be sending some invoice for IRS purpose.  I asked them if there's any custom fees as I have the HST code and it shouldn't be taxed, he said no custom fee but it's more for IRS reporting.

CBP Form 5106

Have anyone seen this before?  It even ask for my Social Security #.
Yes. For my last order of 3x s7's UPS called and required a Tax ID# which for me is my SSN and also required $34.68 for brokerage fee before releasing the shipment for delivery. Out of dozens of orders in the past (all for less than $2500) this is the only shipment where that happened.
