[4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool

Looks like the "0% luck for a day" has finally come to a close at 27+ hours. That was BRUTAL!!!!

I don't think it's luck. There's a pretty consistent pattern there where we have bad luck for that block if the pool hashrate is (10 + n*0.23-n)PH/s, where n is any positive integer. The block at 10.23PH/s was 20.5 hours, and the one at 10.45PH/s was over a full day. Lord knows what would happen if we actually hit 10.67PH/s, it could be a couple day long block.

I hope slush looks into this and can find the error in his code. These long blocks need to stop.

I get the feeling people took your comment seriously

I know MrTeal's been around on the block for a while.  I trusted it was "tongue-in-cheek".  Doesn't change the fact that I'm a sucker for talking about formulas and numbers  

But I honestly am quite curious about the recent jump in pool hashrate.  10% in roughly a day?  That's a pretty good jump for Slush, which has been bouncing between 9.5 and 10.5 PH for weeks now.  Yet according to blockchain's distribution chart, Slush has dropped to only 2% of the network hashrate.  Just looking at those two numbers, you would think total net hashrate (and difficulty) were shooting up again, but we appear to be due for another semi-marginal difficulty increase.  Just my observations.

CEX is down, and antpool dropped 15 PH at the same time... My miners are not going to their backup pool (slush), something is fishy. I will go out to the remote location and switch back slush to primary, I'd rather have 24 hour blocks than 8 hours full blast lost mining.

If your miner is not mining, does it still consume power? Surely there is some code there to stop power consumption on idle...

Yes, they should go idle.  All mine do.  Some of them beep as well to tell me they're not mining.

No they still use too much power when idle

The devil made him do it.

That guy's always whispering in my ear.

My Kill A Watt meter was defective when determining power consumption of my rigs.  In fact, it has burned out completely now and will not work.  I got information from another buddy who has a working watt meter and came up with the following results:

I HAVE DRAWN THE CONCLUSION IT IS NOT WORTH UNDER-CLOCKING THE S3 or S3+ [At least at present price of bitcoin].  I don't know that it would ever be worth under clocking it?  I can see under-clocking to make more power available to add more rigs with a higher hash rate and better power efficiency to your present set up.  That's about the only advantage.  As well as having a faster interface with the new firmware upgrade.

I have tuned my S3's back to .725 volts and default frequency instead of slightly over clocked frequency of 237.5 MHz.


S3 @ 270 watts [under-clocked at 175 MHz @ 0.68 volts (0680) and 340 to 360 GH/s (I chose 350 GH/s for the math)]

$0.106 (10.6 cents) per kWH power costs for 270 watts:

Cost Per Hour:   $0.028620
Cost Per Day:   $0.686880
Cost Per Week:   $4.808
Cost Per Month:   $19.23
Cost Per Year:   $250.02

Power costs at $0.106 (10.6 cents) per kWH for 380 watts:

Cost Per Hour:   $0.040280
Cost Per Day:   $0.966720
Cost Per Week:   $6.767
Cost Per Month:   $27.07
Cost Per Year:   $351.89

With BTC @ $273.471 & Difficulty at 46,684,376,316 and S3 tuned to 175 MHz @ 0.68 volts for 350 GH/s @ 270 watts:

Mined Per Hour:    0.0001571  BTC   $0.04296  USD - $0.028620 pwr. costs = $0.01434 per hour
Mined Per Day:     0.00377  BTC       $1.031  USD - $0.686880 pwr. costs = $0.34412 per day
Mined Per Week:   0.02639  BTC       $7.217  USD - $4.808 pwr. costs = $2.409 per week
Mined Per Month:  0.1131  BTC         $30.93  USD - $19.23 pwr. costs = $11.70 per month

With BTC @ $273.471 & Difficulty at 46,684,376,316 and S3 tuned to 237.5MHz @ 0.725 volts for 480 GH/s @ 380 watts:

Mined Per Hour:    0.0002155  BTC   $0.05893   USD - $0.040280 pwr. costs = $0.01865 per hour
Mined Per Day:     0.005171  BTC     $1.414       USD - $0.966720 pwr. costs = $0.44728 per day
Mined Per Week:   0.03619  BTC      $9.897       USD - $6.767 pwr. costs = $3.13 per week
Mined Per Month:  0.1551  BTC       $42.42       USD - $27.07 pwr. costs = $15.35 per month

When I get a miner I just plug it in and leave it alone.  Works out well that way.

When you set back to default settings on the S3 is that by putting 0725 in the voltage?

I'm assuming it is the default.  I really don't know for certain on the older S3's before the S3+ came out.  I do know that is the default on the S3+ models.  I know this because I got two S3's of the last batch (batch 11) with the January, 2015 firmware and they were default at 0725.  I went ahead and put my old S3's at 0725 volts.  Then shut it down and turn it back on.

EDIT:  I've been up all night doing taxes.  It is 10:20am and I have not had sleep since 2:30pm yesterday.  It's night night for me (bed time).

@kkurtmann Well, it's just simpler to have everything synchronize over on port, now you need two solutions: 1 webserver and then 1 socketserver with memory leaks, file descriptor leaks, thread management, etc. Basically it's the way we should all go; microservices HTTP-only is a good standard so firewalls and scaling works the same way everywhere, language agnostic, so we can focus on the product with different tools; because developers want them, not because some guy with a suit & tie had a bad morning and needed complexity to keep his job.

Also if you wan't mining to work on port 80 you need it to be HTTP.

Bloody hell.....1 day, 4:50:16 again and again.....?!

And Poolluck at 0%!!

Whats up? Too much pooljumpers?

This sucks all the time!

HUGE block for 11PH. Where did this pool BW.COM come from? They appeared over night and have some big power. Oh and its a Chinese pool and google translate doesn't translate the page.

They are located in the same physical structures as AntPool: https://bitcointalk.org/index.php?topic=969823.0

That thread doesn't mention them being located with AntPool. Is there another post you meant that does?

I still don't fully understand mining, so pardon my ignorance if this has been answered or addressed already, or if this is in the wrong thread. Thanks for any insight into the issue. I use Slush pool as my primary BTC mining pool, and I currently run 2 underclocked Antminer S1's on the pool at 130 GH/s. As far as I know, Slush pool DOES NOT merge mine any alt coin of sorts, so this is where my problem arises... I know that the Bitcoin network difficulty is at 47427554950 and I would need a "BestShare" greater than that number to find a block. One of my Antminer S1's report a "FoundBlock" and this isn't the first time this has happened at Slush pool for me, however my "BestShare" is only 66,379,851... My main questions are: Why does this happen? Does Slush actually merge mine and just not tell the users? Is my Antminer S1 just being glitchy? Does the "1" under "Stale" explain this? I did a little bit of research and the only altcoin that I found that can be merge mined with BTC AND has a difficulty below 66,379,851 is i0coin... Did my miner find an i0coin block, because it is possible to "merge mine" with Bitcoin? Here is an image for reference:

Hi, Haven't a clue personally.  Hopefully someone will provide an answer but this forum is like a ghost town lately.  Sounds like most home miners have gone into hiding or retirement.

Looking at your image, you may have slush as your main pool, but your S1 has also been mining elsewhere during the session it reports a block as having been found (i.e your second pool). If indeed one of your secondary pools is an altcoin one, then that is where you found the block (as clearly your best share is not big enough to be a BTC block).
Additionally, I do not believe that a stale share can also be flaged as a found block, so that is that with that.

[bigbitmine]

Yep, that should solve that.  Good to see there's still life out there is Slushland
