ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

[Prelude]

So I started to notice a big difference of temperature between my two S7 batch 6 units. One is running at 58 C and the other 66 C. 8 degrees lower than the other, with the same PSU, in the same room in the same conditions!? So I looked at the front fans and also notice they are different!



The fan on the right miner runs faster and obviously cools down better the miner overall. I've set both to 24% fan speed.

Right miner: @ avg 58 C
Speed (r/min)    2,400    0    2,400

Left miner: @ avg 66 C
Speed (r/min)    2,520    0    1,920

I've seen the post from Prelude and looks like his fans are the slower one. Anyone else got a miner with the better fans? I thinking about changing the slower fan for the same model as the fast one in the other unit.

Hmm, that's really weird. Looks like the old fan they used on the S1 and S3. Are you sure the one on the right isn't the 1920RPM one? The 3 running 24-2500RPM are like the one pictured on the left, no? The fan on the left is the standard bitmain fan since S4.

Yeah, very weird. I wonder what Bitmain has to say about that.

I'm sure because although I received both miners at the same time, I had only the left one turned on until I get my 2nd PSU for the right one, and it has been always running with these RPM.

First there is a pool section. => https://bitcointalk.org/index.php?board=41.0

Second, current luck doesn't represent the future

Third, thanks but no thanks

I understand there is a "pool section."

I'll take it down in a few.

As for luck...  They had only 1.1 PH/s a few days ago.  Now they are over 4.6 PH/s.  They've recently had a couple of decent size farms add some hash in the last couple of days to make it where the variance is more manageable.  Hence, the rise in luck with better variance.

Trust me on that : current luck doesn't represent the future whatever variable/formula you want to put into your reflection

I'm aware of that.  I'm mainly referring to "variance."  The variance is more manageable with a higher hash rate on a pool operated by top notch staff when "luck" is low.

Totally opposite on Slush Pool.  They have a hell of a lot of hash but staff that doesn't know what they are doing.  Look at the orphans they have...

I would be willing to bet if you saw all of the hash rate you see at Slush on CK/Kano Pool, you would not see all of those orphans.

Pointed my 4 S7s and Avalon 6 to Kano right after your post, hopefully, you are right. 21 hrs no block yet, missed 2 payments ~$65 each from antpool already. I will continue to run at Kano a few more days to see if I get comparable payment.

You have to mine at kano for a little over 5 days to start getting full payouts.  Look at your shifts page.  When your shifts get to the red line then you are getting the full payout.  So your first payouts will be less than later ones assuming there are blocks found in the next 5 days (which there definitely should be).

Also, S7's under 4 BTC now on bitmain's website.

So what you are saying is if my file system version on an B3 is 9/15/2015, i should not upgrade to the 10/23 version on their website.  Its working just fine with very minimal hardware errors

exactly  if it ain't broke don't fix it.

use manual fan settings of 50%

  to achieve fan speeds of 3600 rpm to 3600 rpm

this will prevent unit over heating  if you drop internet.

Of course if  you want you can go to 60% or 70%

once you set  fans  at 70%      you are basically the same as 100%.  


most of us have found that manual and auto tops out at 4400 rpm.   And the high settings of 70 to 100  are all just about the same.

Here is my batch 2 ------------- I leave it alone as I don't except to do better then this: 

60% fan setting




50% fan setting

So, first 5 days or so payouts will be significantly less than other PPLNS pool. I received a payout of .00333 today from Kano. How about after 5 days, will payouts be about the same as other PPLNS pool such as Antpool or better? If it is the same, I don't see any benefit in mining at Kano, other than supporting lesser hash rate pools.

You can expect a little bit more per day than other pools as long as kano.is continues to find an average of 1 block each day at present hash rate.  According to wisdom, the present hash rate of kano.is (4,717 TH/s) should mine 28.08 BTC per day.  That's a little over 1 block each day.  If kano.is can maintain that one block per day average, you should see nicer payouts than what you would normally receive on other PPLNS pools.  If kano.is maintains 1 block average per day and adds another block on top of that one block or even two blocks over that one block average during one particular day, you will absolutely LOVE the payout for that one day.

As the hash rate increases on kano.is, the number of hours it takes to reach 500N should get less and the number of blocks should increase of course.  The advantage during times of good luck on a small pool like kano.is is at present is the day 2 or more blocks are found after maintaining the average blocks found for overall pool hash rate.

The dates you see a significant number of days between blocks are days in which the pool had well under 2,500 GH/s most of the time.  At that hash rate, it would be normal for the pool to find one block every 1.5 days.  The payout would still be a little better than other pools each day on average as long as the pool found at least one block every 1.5 days at that 2,500 GH/s hash rate.  The days in which kano.is finds more than the average estimated blocks [While maintaining average blocks found] are the days you find it worth staying there.

EDIT:  Yes, you will continue to receive payouts after you left kano.is IF you decided to leave. If kano.is was to maintain 4,700 GH/s at present while you were gone, you would continue to receive diminishing payouts over the next 5 days as blocks are found.

What's important to understand is that your 5 days of building up shares isn't lost. When you stop mining there, you'll continue receiving full payments on each block for the next 5 days, even though your miners aren't mining at kano.is anymore.

Give it time, you'll love it. You'll make more than at antpool.

Got it, that's what I wanted to confirm. I will stick with Kano, probably point 2 more S7s too.

I think a reason for it growing is some like to support ckpool which is not a bad thing at all.  The pool forum has been kinda interesting to say the least.

You can read kano on SPV Mining: https://bitcointalk.org/index.php?topic=1274066.0   Normally the pool forum is not nearly this interesting.  To see him care about bitcoin I think is gaining him support as far as more pointing machines there.

does Batch 8 have shipping included this time ?
When I click shipping with DHL it shows me 0 BTC for shipping.
Is it possible ?

Nevermind, shipping price got updated
(it was a nice dream tho)

back to the topic of s7.

did you guys noticed that s7 produces quite a bit of rejected shares ? especially if you are oc'ed ! it's quite alot mining even at antpool the creator of antminers. you DO NOT get paid for reject shares even if you are at a high hashrate ! so that means lower hashrate will earn you more btc compared to highers hashrate *ie oc'ing the s7 too much* & also saves you power & probably other costs or wear & tear of running the miner.

if you can, please try with stock clock & overclocked mining at the same pool same s7 miner for couple of hours & compare the results. i can be very wrong but i don't think that i am.

i moved my miners roughly 80ths +/- 5% to K's pool & the miner stats page is accurate not like ant going all over the place for the past week. yes the payout sucks initially for couple of days but it will ramp up. be PATIENT ! if you do the math & *IF* K pool does perform on the avg, yes you will be paid more than other pool atm. just a little like p2pool, u need time to ramp up the hashrates & payouts. so far the s7 stats on miner side & K pool is very close & lesser rejected shares compared mining at antpool.

miners should support smaller pools which are doing the right thing especially with good support & community. do NOT support larger pools which are NOT doing the right thing for the bitcoin community.

[fr4nkthetank]

Since we are on the topic of where to point the s7 to hash (still relevant...) - does anyone have an informed opinion on antpool PPS vs F2pool pps.  I'm sure Kano pool is better though, over the course of 6 months lets say.  what is it 0.9% fees vs 2.5 or 4 with pps.  On another note, Can the S7 do load sharing ?  And if so, has anyone tried it ?

I suspect it can but via ssh not the gui.

As for pps I use F2pool never tried antpool pps

Amen Brother!. I've tried them all, and been at Kano since early June. Fantastic results and awesome support, Kano answers every inquiry on the form, does the right thing for BTC and has the best back-end mining code on the network. Just last week, people are finally starting to see that and we are at almost 5PH. Keep spreading the word and be at 20PH soon. Very happy here and payouts are the best once you hit 5N, which is getting shorter with higher hash rates.

[dmwardjr]

Well said, gents!

S7's [And most any other rigs for that matter] will have more stable hash rates at Kano.is than any other pool.  I let the pool determine the diff for my rigs rather than manually setting the diff.  You have that choice as a miner; which is great.

We found two more blocks [When the present hash rate requires only 1 block per day to maintain average or very close to 100% daily].  Which see:

I'll take down the screenshot in a few:
