Unofficial Spondoolies SP20 thread

[Guy Corem]

Phil is this your listing?

Yes it is.  I have 7 running and 2 on the way. = 9 units  I have 1 s-5 coming it total of 10 pieces and just about 12th in hash.

I want to keep all of them but it is just a little over my power envelope.

Here in New Jersey it reached 62F on tues and the house got really warm 80f .

 This is with 7 x 600 = 4200 watts.

 Even though I can provide the 6000 watts to run 10 pieces I am thinking it is just a little more then I should shoot for.

 So I offered 1 sp20 for sale on ebay.

 I am hoping to run 7 sp20's and 2 s-5's = 9 pieces

\
When I look on Spondoolies website for the latest offer it says that if these are reshipped or resold the warranty will be void. Is the warranty nontransferable on this unit as well?

Only the mini farm can't be reshipped.

I don't blame you on selling the value of these things is dropping like a rock considering they can be had for $500 free shipping if you buy 2.

well if you look at my ebay link you will see I have been in business for 11 years and my reviews actually amaze me.  I have 7 in my house and 2 on the way.  that is 9 I can not run 9 in my home.

So don't you think I would make good to the buyer on ebay?  (yes I would )  I would do an exchange from one of my remaining units.  Then I would talk with spondoolies tech and hope they would help me out.  I now see that they say they would.

Please tell me where I can by 2 sp20 for 1k shipped

Thank you sir.

[Dr Charles]

please excuse my laziness here... I read the first couple pages but didn't see the answer.

Can anyone compare the sound of the SP20 to that of the Antminer S4? I currently have an S4 running and a couple SP20's coming in and want to know if they will be louder than the S4, about the same, or if the S4 will drown them out. For example purposes the S4 will be running on default clock and voltage and so will the SP20.

thank you.

Sorry I don't have an s-4 .  if you run these at 1200gh and 40 fan speed  or 1000gh and 15 fan speed via ssh they are okay.  if you run at 1400gh and above with 60 fan speed and above they are loud.

My meter reads 65db at fan speed 15.  the pitch is not a whine it is bearable in an un-used room.

 I would not run it watching a tv in the same room.

 But if I run an s-3 with a slight down clock to  freq 212  and this fan

I am good to go db under 48

At stock speeds, I would say they're close to the same noise.  That's just based on my hearing, no sound measurements.

I did a fan mod for 1 sp20.

I pulled the fan out completely and added a silverstone to the external end of the miner.  this is the fan


http://www.amazon.com/gp/product/B00A460TK6/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

it allows sound to drop to 60db and run about 1150 vs 1000

I can hash at 1158gh

all temps are good

I tried that fan too, a lot of air gets lost in the gaps, thought maybe using tape to black out the gaps where it overhangs the side of the case.

Thing is, what I have been trying to do is find a fan that lets me run at max TH, as good cooling but with a lot less noise than the stock fan. Its proving difficult to do

yeah this has it quieter and at 1158.

 the gap issue can be fixed by a piece of felt.

I think if I find a correct push fan maybe this one

I could do 1400 pretty quiet. this is not a big issue for me  but I love to tinker around.

I had these in the house----------after I put that felt on temps dropped on the 2 high ones from 115 to 110



closed two gaps one on each side


db is 60 but there is a lot of ambient noise the room is 52db due to all the fans in the garage.

Are you sticking with a Pull configuration? Have you tried switching to Push, or Push+Pull?

Looks like prices will be dropping considerably on newer rigs come new year's.

pull and while it is quiet it is not quite correct. 

 next will be push- pull

[philipma1957]

Outside temp is now -2 deg.  I put a drilled metal plate to stop insects or small particles to be sucked from asics.

My record till now is that. Just like is advertised

yes the key is proper cold.    not too cold  -5 to +5c     or 23f to 40f   good psu  high fan and boom 1700gh is yours.

So who keeps their home that cold?  This is suppose to be a 'home' miner.  I'm looking forward to receiving mine in the next couple of days.  I knew about the loudness of the fan, but didn't realize it doesn't reach the stated speed under 'normal' conditions.  We don't even keep our server rooms lower than 65f.

Oh well, live and learn.  I'll compare them to the S5s when they arrive and decide from there based on $/gh & j/gh what my end of year purchases will be.  Right now, the S5 is leading on the 'expected' $/gh for home mining.

well many of us have said it is not really a 1700 gh miner

[bgibso01]

well many of us have said it is not really a 1700 watt gh/s miner

I do agree and appreciate the reviews I have seen.  I just did not see many discussing the actual 1700 issue until after deciding on the GB.  Most reviews have been talking about the undervolting rather than actual performance to spec.  Again, for just a couple of units it's not really an issue.  Now if I want to spend $10k for year end, then it would add up.

actually I am going to run my sp20 at   1185gh  @ 625watts.  which is as efficient as an S5 and much more flexable visavi configuring voltages.

we knew it before de GB that is hardly reaching 1.7gh/s!
