many people don't understand the many pluses of home mining, but as time goes on and the network grows we will get squeezed out due to power limits.

still looking for the db meter.  getting too much gear in the house.

I am running 10 s-3's  and 1 sp20e  

I have 9 s-3's in the garage near the work bench and I have the sp20e


Figures I set the gear all up and temps jumped to 74f .  making the attached garage 92f and making the house 85f had to shut gear off over night to be able to sleep.

Today is cooler around 62 f house and garage are both better.

 I will photo setup.

@ sbogovac    raskul was helpful in selling it to me.

@ raskul    thanks.  and I am send some more hash at mmpool

3 s-3's and 1  sp20

they stack well and air is feeding out my garage's back door 2 quality psu's the egva 1300 g2 and a seasonic 1200 watt plat.

my garage can safely do 5k watts I have 5 20 amp 120 volt  circuits  into it.  when i am running all 10 s-3's and the  1 sp20 I am at 4.kwatts

for now the issue is heat since it is about 57f the garage is warm but my entire home is also warm.  So realistically  I am close to max. my hashrate is 5.5th .

 I could fit 2 more s-3's or try to arrange a few more sp20's .  my 10 s-3  to 1 sp20  =  5.4th 4kwatts

should be  5 s-3's  to 3 sp20's  = 6.5th same 4 kwatts.




3 more s-3s'  they are above the fist photo

better yet 6 confirms

now to all those happy ones.  I will mention a pool a while back had  .99 and .99 cdf back to back. 

So our .98 while brutal  could be followed by a few .91's in a row.  Or we can rip 3   0.11's

Anyone that has trouble grasping this  get a pair of dice.  Toss them over and over for 360 tosses.   mark only snake eyes.   you will find interesting patterns .  you should get 10 sets of snake eyes in 360 tosses.   1 set around every 36 tosses.  you will find you may vary far from that.

  this round of shit luck would be like tossing 150 times before snake eyes turns up

yeah looks like east meets west is a match in heaven.  the newest s-3+ has volts and freq control the sp20e has the same. pairing them on the evga 1300 g2 has me fairly happy about extending the mining time with the gear.

My goal is to continue to tweak the two.  I know evga 1300 will put out 1200 watts day in and day out.

I am hoping to see if the settings of the two will give me 1900gh on 1150 watts.

the only worth while cloud is renting and point it were you want.  nicehash + westhash  and a few other companies come to mind.  standard cloud mining is meh at best.

it is way better then the prisma .  

  the best i got my prisma to do on under clock was 1000 watts and 1300gh  

 so far the  sp20 has done 747 watts and 1353gh on under clock  

if you do the underclock and set fan to 40 it is not as noisy as the prisma.

nice one I am on board with this!

okay I add an s-3+ newest version it also arrived today.

the sp20 = 1323 gh  1)fan set to 40 2)volts to .62 3) watts to 175   = all low settings

the s-3+ =   430 gh 1) freq set to 212.5   and  2) new option volts I set to 0.68  also lower then stock.

total gh     = 1753
total watts = 1035 to 1055    That is well under the evga 1300 g2's limits   it comes to  .59 watts to .60 watts combining both pieces

you get max value on the evga  .  my guess is I can go higher but with the unusual warm weather I will have to wait until weds to try over clocks.

VERY HAPPY WITH THESE RESULTS.


 size is close the sp20 is longer leaner.



both units under-clocked it starts at about 1035 watts on this meter and 1055 on my other meter




pretty small foot print and you can also stack

do you mean this set of numbers?


Temp Front / Back T,B
38 °C / [b/74,71 °C[/b]

if so what is low enough?

right now my room temps are very high due to 74f temps in Howell NJ USA

I have now set 1 sp20 and 1 antminer s-3  one 1 evga 1300 g2

pulling 1043 watts for the two units 426 gh for the s-3 and 1322 for the sp20   so 1043 watts gives me 1748 gh .

I was thinking 1152 watts and 1650-1700 gh using an evga 1600 p2

this is much better.

I would and I will but with my sp20 using 746 watts from an evga 1300g2 if I add an antminer s-3 clocked to freq 243 or 250 it will do  490-500gh

 and burn 380 -390 watts.


thus the evga 1300 g2 will do 746+ 390 = 1136 watts and give me 1350 + 490 = 1840 gh

grand totals of 1136 /1840 = .61 watts a gh.   and only 1 psu  and I can manage sound levels

to do max hash for both units. I need a second psu .

 I could come close to 2150 gh vs 1840 gh  but the extra 300 gh would cost 1 more psu and close to 450 more watts.

with current prices for power and btc I am better off with underclocking.

don't have a smart phone I am stubborn about it.  still looking for the metere.

at fan setting of 40 the gear is about = to an s-3

at fan setting of 80 the gear is about = to the asicminer prisma.

frankly for me I have to do settings of 40 or 50.  as an aside it got to 74f in New Jersey today.  My wife and I went to walk on the boardwalk at the Jersey shore which is nice.   But my house is hot really hot right now 84 F

I expect my numbers to improve on the sp20 once it cools back off on weds.

nice numbers for the btcguild  over 1400  for now it will be under clock maybe on black friday I will see if  over clock works well

 not under clocked see my settings above

after much testing and firmware down to fan speed of 20 the machine is 67 db.

with super underclock to 1025 gh and 477 watts.  fan can be set to 10 or 15 vis ssh.  It is still not a quiet miner.




I spend 746 watts and I am getting  1350 gh  or 0.55 watts per gh this allows the lowest fan setting  40..   give me an hour to find my db meter.

  right now I love this piece of gear……….. 746 watts for 1350gh   out fucking standing.

one more space
current settings

these are all low settings
my fan 40 stock fan 80   still loud but can be tolerated
voltage on all four boards .062   stock .068

GENERAL BACKGROUND BS

 Who am I a miner been mining since 2012.
 Why this thread I like the sp20.
  Disclosure I have 6 of these.  
  First one sold to me by raskul  it was 795 he gave me a coupon it was 715 +119 shipping = 834 Raskul links to spondoolies-tech

  I got a deal from an ebay seller on the second one I paid about 700 after an ebay coupon.  ebay is always hit or miss this was a triple with 2 men on.

  3,4,5 black friday/cyber monday  sale 3  different orders  each was 695 + 119 shipping or 814  raskul sig link for these 3

 6th  Spondoolies contacted me about a t-shirt offered on for free.  I said cool but since you gave out 10 machines to legends for free how about selling me the sixth one cheaper. So the sixth one cost me   814-150 = 664 and I got a free t-shirt.   and used  raskul  link again.



That is my full disclosure. I do not get paid for this and if you look at my signature I do not get any referral money for sales of this item.


The good stuff starts here

  Below are the links I have found that I think are good for buyers and or miners to look at.

Right off the bat   the machine's 1700gh rating is like saying my Kia Forte is rated to drive at 120 mph or 190 KPH. yeah on a slight downhill road with the pedal to the floor. On a cold 5C but not too cold day -10C.

Think 1600gh for your max.  with fan on 80 or 90 , cold air and a good psu.


FAN is loud. even at setting of 20%

In my opinion this is the best miner I have ever owned.   Why is that?  it  downclocks really really really well

 I am debating if I should go from 6 to 10 of them. ----- note I ordered more for  a total of 10

1 more to come Note please let me know when you post I will put your link in.

Mr. Teal did I miss your review?  I think all other ones are listed above.  Mr Teal is in the House! nice tear down of the sp20e

I believe this is a full house.

Below is the original start of thread.

Okay I purchased one last week it arrived today. I will show lots of photos .  I will test it on various settings with different psu's.

I self mod for a few reason's I don't want to hear it won't roi or it will roi.  I don't want to read nasty insults.  

This is for gear head tweaking dudes and dudettes.

Many photos to come.


box is about the same size as an antminer s-3



bottom open not top



cardboard packing my  guess is rough handling and these would struggle- so far 8 have arrived safely



the money maker is revealed

after seeing my results try under clock and under volt

I am using 747 watts to get 1380gh

I think you could run 2 units on that psu

I will test mmpool on tues.


the sp20e works fine.  but right now a lot of my gear has rolled over and off mmpool  is there an issue with the pool?

I am getting really good numbers  with lower :
watts 180
fan 40
volts .062
max volts .068

.55 watt per gh damn good
