Unofficial Spondoolies SP20 thread

[philipma1957]

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

Is it really 60+ db?

[notlist3d]

I'm loving mine great machine.  And nice pics of it.

It is a small form factor.  I kinda like it.   Long and slim.  And the under clocking is impressive.

philipma deserves some credit for amazing underclock settings.  This chip is amazing.

[philipma1957]

Is it really 60+ db?

 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.

[Biodom]

Is it really 60+ db?

yes, what is db reading when at various watts, including default?
In addition, please post about what kind of pitch it is (low, high, etc.) and, if you can, compare the noise of S3, S4 and Sp-20
if you don't find the db meter, just use iphone or android phone-there are free or almost free apps that do it
Thanks

Yes it is, but it actually matters most at the "final stretch" of the miner lifecycle.
Unless it is a hobby, which it IS admittedly for most of us at current BTC prices, then don't you want to try to produce as much as possible as soon as possible?

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

[philipma1957]

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

[pak13]

fantastic independent review and comparison! Kudos!

[Prelude]

Thanks for posting all of this.

If I can make a suggestion: Plug the 2 extra PCI-e connectors on the S3. I know that they are undervolted + underclocked, and that they don't need them, but you will be delivering current to 24 pins instead of 12. Won't change anything for the PSU wires, but you'll reduce the stress on the 2 plugged PCI-e connectors by half.

BTW, that PSU is a total beast. You can run it all out 24/7 in 50c ambient without it breaking a sweat.

Cool report please if you can post the photos on the picture of your rigs thread as well
many will apreciate them.
Also nice to see the low power this means longer presence in the shack..

yeah my sp20 mines at 1750 TH using 1200 or so watts.

[raskul]

excellent post Mr Ph.
I have 2 S3's and 1 SP20 on it's way, I may just go with getting another SP20 (if mmpool ever finds this block!) and do the same as you have done. I've got 1 x AX1200i and 1 x EVGA 1600 80+ so it looks as though I should be able to replicate your setup.

looks like SP-Tech have delivered on their expectations once again

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.

[sbogovac]

Where did you buy the SP20?
