I once saw 1680GH on one of my four SP20s (set at 0.75v and 12c intake), but it isn't typical.  It also does 1640s at 23c.  It hardly breaks a sweat doing it (very little thermal limiting) so there is probably plenty of room to overclock that one, but I'm not interested due to the efficiency loss.  That said, that same "overachieving" SP20 doesn't underclock anywhere near as efficiently as the others. 

On two others I see closer to 1600-1620GH at 0.75v which I consider typical for a SP20.  The last one I have is an "underachiever" which struggles to get 1550GH at 0.75v (with four different ASICs hitting thermal limits in the 630-640s).  Although an underachiever at top speed, that one for some reason can underclock far better than the others (at 0.62v I see 0.48w/GH at the wall on that one-- something the others don't even come close to).

Lately I've been running them all at max 0.72v as the optimum profit point for my power rate.  This morning's readings (low to high) were 1461-1500-1530-1546.

they are very much like gpus in that respect.  3 indentical gpu's will all have different sweet spots.

and all of they power a shit load of extra power when pushed to the max.

that said I have 9 sp20's.

 I never expected them to do 1700 or 1600 I wanted them to do exactly what they do downclock  to 1100gh and use .5 watts per gh.  I hoped to use 2 per evga 1300 g2 psu as I have quite a few of them from my s-1's then s-3's.

I am happy with them .

That's exactly what I do with mine phillip, i have 8 of them running off of 4 evga 1300g2s and I get 1.2xx from each without a problem.

Same here, the one running with the fan at 30% perform a bit better then the other one running at 40%. (around 20gh/s)

Any official release of firmware 2.6.14 ?

2.6.14 was available today for download for the SP35.  Just got my units and powered them on yesterday, they shipped with 2.5.something.

With the shipped FW version the units were barely doing 3TH/s.  With 2.6.14 so far they're running about 5.4 TH/s after an hour.

Without needing to flip through all 500 pages of the thread, is there any good summary on tuning the SP35 for max performance?  I'm in a datacenter setting with 240V power and am looking for best hashrate, not the best power usage.

[VeritasSapere]

No, not bad at all.
You guys have been responsive to the squeaky wheels, especially the ones with valid points and issues.
People sit up and pay attention when they see someone treated well by a company selling products they use.

I need a bit better BTC price, another drop in SP price, or a group buy to pickup a few more units, and I am not complaining about the price you are at, but I would order today if SP20 was at $370.00 EA or 3 for $1050.00.

Of course the business model changing to straight industrial co-op concerns me as a home miner. I hoped to cut my teeth through home mining and open a side business this summer strictly dealing with crypto in the community, help other home miners get started, and a few other ideas. If I have a hard time getting product from the best miner manufacturer it will be kinda hard to recommend them to others.

That is what I understood from Guy in a recent post, and I've heard about it and talked about it with other members.
Is that the true intent? In the future primarily dealing with Industrial accounts, or will you sell whatever unit you are building to anyone, but your focus is listening to the feedback from the big miners? I should probably ask Guy, hope I'm not putting you on the spot, and if you do not know the answer, what is your opinion, thoughts, how will it affect the future of Bitcoin mining, and how does it specifically effect decentralization?

I would like to know the answer to this question as well. I can be more specific though. Will i be able to purchase the next generation of units of you as a small “home miner”, and will i be able to fit them inside of my soundproof server rack at home? This information is relevant to me so that I know whether to wait for your next generation of miners or to purchase one off another company. I already have two SP31's and they are running great, had some problems in the beginning but spondoolies support sent me a new unit without delay, hands down the best mining manufacturer in the world right now IMHO. It would be a shame if I would have to take my business elsewhere.

I think 5.4th is pretty close to max.

In case it's not obvious to folks, it looks to me like Spondoolies has gone ahead and made firmware version 2.6.14 the "now most current" firmware for the SP20, without choosing it as a test version via a "Manual Update".

you will have room to spare

these are lower then you need


you will pull 565 + 565 watts = 1130 watts . after it runs at this  for a day or 2 you can bump up just a bit

That's almost the exact same setup I run on 5 of my SP20s.  Three are powered by two 1300G2s and two by a single.

I am glad to see i am not the only one having a miner going down without any reason, however in my case my psu switches off and only starts after i have let the psu without power for some time.
I will try the sd card option as well
Also noticed since zvisha set it very low speed it seems to run a bit longer now, really hoping it not again to stop
I does not matter which psu i use all the heavy ones or even a 1000watt and a 1200 watt connected with the weird sp20 it can run for a few hours or a few weeks and then all of a sudden poof its no longer running.
However i am not sure if its the same problem, this machine does need much more power than the earlier bought one.

Oh, man, I hope they send me a good one as I'm hoping to buy more if this one works out good.

It seems to me, you're having some kind of electrical issue. PSU will shut down itself to protect it when faced a catastrophic event, such as overloading. Your miner may be drawing more power than the PSU can give. What settings are you configuring it with?

Sorry missed the post
No the psu's i own can probably run 2 of the sp20 most are 1600 watt 220v and have over 130 amp each.
The other used psu's are enermax quattro 1200 which are known to be able to deliver 1200 watt continue and they baffled me.
The older 1600 watt psu actually runs handwarm on the casing and the cables, while the older quattro's stay cold as ice on case and cable.
However when the sp20 went down was when it was actually running at start 0.64 and max 0.71 (watt at 288 )
The issue i noticed was that the first sp20 i received actually allways ran fine, bu the new one needed between 0.15 and 0.25 more volts to run same speed.
To avoid power being any issue i tried lower the machine to 0.61 start and 0.66 then all of a sudden the machine was off.
So i tried to power it back on but the lepa 1600 psu refused, so i was thinking of a problem with the psu.
Pulled the reserve 1600 watt recom psu from the rack and put the same machine on that and poof back on running.
Time goes by came back from a job and again machine off, and again psu did not switch back on.
Ofcourse lots of bad language ..... , stupid psu ..... now comes the idiot part i put the lepa 1600 back on this machine poof running again (WTH yes it ran again)
6 hours later i check the miner guess what off again, tested the psu on any other miner i have in the house no go not start.
Let it rest for an hour poof miner runs again on the lepa, so i pulled the quattro 1200 from the antminer c1 and put that on the failing sp20.
Running well for about 3 days poof off, (again alot of bad language) again took another approach pulled my 1000 watt nzxt and the other s3 ant quattro psu (1200watt as well)
So both connected to the sp20 so 2200 watts total can never be a power issue. 5 days later poof off again. and since that it random went off switched between all psu's in the house and once in between a few hours to almost a week it went down again.
Sp support lowered the settings because i had set it to factory default to see if that solved it. and weird enough this far no sudden stop yet.
Still the newer sp20 was needing more voltage to run same speed as the somewhat older one.
Yesterday i  noticed the newer firmware so i installed it instant and since that i also lowered the settings for the miner to alsmot the same as philipma1957 is running his.
My setttings are now 0.616 start and max 0.626 i left the max power at 230 it seems not to matter. The sp1 is still running on the 1200 watt quattro and the sp2 has again his evga 1600g2.
So if i look at the power on the wall both should be able to run on even 1 antec 1200 watt quattro because both pull 565 watt max now
What strikes me is that with the new firmware the machine do about 1000 Gh, but it probably will go up in time.


Before you ask the same psu's have been running other machines for instance 2x ant s3 or c1 or some scrypt rigs and never fail, not even went down a minute in months.
If i switch them between sp1 and sp2 they run perfect on the sp1 but the second ... yes the weird power downs. the quottra pro i pulled from my gpu rig runs months in a row never went down at all. 1 hour on the sp2 poof off and refused to start for at least 30 minutes

Lets hope the weird one will keep running it keeps running now , time will tell

[takagari]

What screws fit the holes on the top and bottom of the SP20, I was wanting to secure them on install.

Thank You

[bronan]

During the night the numbers changed
They did run and seemed to use only 518 and 526 watt
But 3 out of the 8  shows blue and on the sp2 showed really odd numbers
I saw 35 hw errors and weird numbers in the sp2 like 343 gh and 42414 asics.
So decided to turn up the voltage a bit.

Hmm i guess i spoke too soon about that they appeared to run exact same now, during this short time with a bit higher volt it changed the sp2 is again slower than the sp1
with new setting applied min volt 0.62 max 0.63,

sp1 : 1055 Gh
sp2 : 997

Am not sure if these numbers are accurate at all, because both seem to have run at 990 Gh during the max 0.626 volt, but if i looked at the asic stats its a mess
numbers of asics and gh being anything at certain moments. I think the sp1 probably does run very well on the quattro 1200 and shows at killawatt 520 watt used
The fan was set at 20 because its -8 C here so pretty cold weather for miners.
This reflects also at the asic stats which showed temps between 32 c and 42 c on the cores, kinda cold enough and maybe even a tad bit too low.

I have changed the fan speed to auto and funny enough it pumped up the fan to 60% and slowly is going down over time.
Will see when i am at the job i am at, by remote what they are at later if i got time.

1600w Lepa is a multi rail PSU. Check your 6pin connectors that go to the SP20 and make sure each 6pin pci-e connector is on a separate rail.

1600w Lepa is a multi rail PSU. Check your 6pin connectors that go to the SP20 and make sure each 6pin pci-e connector is on a separate rail.

I know i am a geek so i am sure as hell know that you can not use 2 rails from 6 because they are only 20 amp
And you can not use any of the second cables and connectors on the same rail on the psu

But i gotta be honest i do not like the lepa psu's, yes they are best priced but to be honest i regret i ever bought it.
The plugs are weak and break off easily and in every way its an obvious cheap build.
If you try to use an 8 pin on the 20 amp rails it often does not even start. ( tried to power 7970 amd non oc'd which has 2 pci-e pin in case you want to oc )

Anyway its besides the point it is connected at the EVGA 1600G2 with its massive 1600 watt 1 rail
After it arrived i was pleased to see the fat cables and insane 9 pci-e connectors
They cost a small fortune but its really rock solid

However if one wants to have a super strong psu for cheap which often does as good as a gold psu, find the antec quattro 1200 (pro) second hand and you have a very good psu.
It even is as good as the platinum corsair 1200 in most cases, both ran with several miners and gpu rigs and give almost exact same readings on the wall.
The funny thing is the quattro is only rated 80+ silver and in my situation beats a lepa gold rated but showed same as 80+ plat in efficiency

Maybe i been lucky with these 2 but i like them a lot, very good miner psu's ( the 1200 means i can constant deliver 1200 watt)
I have not been able to findout what these psu's actually maximum power is.
 
But they have limited pci-e plugs, so you need to hunt down some really nice pci-e splitters on ebay which do not have the scary thin cables
  

[opper]

I have around 9 Corsairs AX1200i . That is the best PSU I have seen and used by far. Although recently I started to use IBM BladeCenter DPS-2000BB server PSU. I am modding them myself with 4 6 pin pci-e connectors and using each of those to power one sp20. They are a single raid 91+ gold psus and are relatively cheap compared to the ATX ones.

Looks like that is the nail in my SP10's coffin. My neighbors should be happy with the reduced noise. Now time to sit on the BTC and hope it goes up.
