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.

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?

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.

"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."

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.

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://bitcointalk.org/index.php?topic=789369.0 just up to 12ph
https://www.kano.is/
stratum+tcp://stratum.kano.is:3333

https://bitcointalk.org/index.php?topic=559011.0  lucky to get 100th
http://mmpool.org/
stratum+tcp://mmpool.org:3333


https://bitcointalk.org/index.php?topic=1330452.0  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:

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.

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

Stock picks based on past performance have nothing to do with random chance. In stocks there are Humans 'with a Plan' guiding performance vs random events. That Human influence throws a huge bias in a stocks performance. Yes random outside events will have an effect on performance but nowhere as near as much as the Human guidance does which will deliberately work to offset serious random disturbances..

If anyone is looking to sell a 162 chip S7, I'm buying. Transaction will be escrowed with OgNasty, PM if interested.

[charles2k]

After confirmation order this red written message appears (if shipping by Fedex):

"Generally, shipping with Fedex will take 3-5 days.But if it's spot checked by customs before exporting, there will be around 2 weeks DELAY.You only have 5 days to process customs clearance, if no action or failed, miners will be returned to sender by customs. You'll have to cover extra cost. "

Why? I never heard about it.

With UPS shipping option there is not such message.

Lots of scams lately.  People been randomly asking me if I wanted a S7 for sell but once I asked about escrowed, they would say they don't trust those people and reference previous escrow scams and request to go LTC escrow route.  Buyers beware.  I know some of you are complaining that this is off topic but it isn't as it's still S7 related and they're trying to feed off the audience of this thread.  I think it's the same person as I would get random message saying they saw me asking to buy S7 but I never did say that.  If they don't agree to Escrow, you know it's fishy. 

@ Charles2K  - There's always been that message for FEDEX.  My brother in law paid extra to go with UPS after he saw that message and he end up having more headache then I did and pay $32 fees for 2 S7 vs none for me via FedEx.

Thank you for that!

Are you running the Bitmain 1600w PSU directly to the wall? or using a pdu or some other sort of surge protection?? That will determine what plug to get.

I picked up some used APC AP7911 switched PDU's which work awesome and can be controlled remotely. If you go this route you will need c14 to c13 cable to run the Bitmain PSU to the AP7911 PDU and then you would need a NEMA L6 30R outlet. The APC Ap7911 has an AC power cable already.

[Romanko]

Yeah I can get him to do it this thursday.

  We mined at f2pool since dec 29th

I will do a chart show him what it netted and then get him to to mine with kano.

Good stuff! I'm confident more will be earned using kano over the same length of time.

Got your point fellas)) will examine the info and direct my miners to keno or some other pool, maybe eligius.
There was time when me and my fellas mined at btcguild but almost all of us fall for the daily payouts from f2pool.
And according to my example everybody moved to f2pool so can I do it to some other pool.
Of course I want the best for myself and the fellas, but we do care about the the enviroment)) 
Not so long ago when my buddy purchased a node and was minig solo his server was constantly attacked (we think from china), and he stopped the solo and continued with f2.
But what wanted to say - even if we have payouts less then now -3-5% it will not effect our willingness to care about the btc ecosystem. we do care

[mavericklm]

Kano is the best!

Anyone identify the place of the thermal sensor on the s7? Maybe this time they didn't put it at the middle of the blade as in s5!

[rockyforever]

I have a couple 162 chip miners and can hash them well above 5200 smoothly without hardware errors. I will receive my batch 9 tomorrow, not sure how much I can push these to. I usually wait until Philip reviews the higher frequencies lol

Can you power an antminer s7 off an evga 1300 and a corsair 500 watt psu? I'm thinking the 1300 for the blades and the 500 for the controller. Would this setup work?

[notlist3d]

Can you power an antminer s7 off an evga 1300 and a corsair 500 watt psu? I'm thinking the 1300 for the blades and the 500 for the controller. Would this setup work?

Assuming B8 or B9 unless underclocked I don't see running 3 blades off 1300 watt's.  Also I don't think it comes with 9 PCIe cables (could be wrong been a while since I have opened a box to one).

It would be the evga 1600 to run all 3 blades if you want to do it off 1 psu on evga series.  I would look at 220/240 if at all possible and there are some great server PSU's.  They have really taken over S7 market on PSU's being used.
