Unofficial Spondoolies SP20 thread

[DevonMiner]

to me if i built it and sold it I would call it a 1500 gh miner.

Sponds do play the game of claiming the absolute highest hash rate for their kit (in ideal environments), and as we have seen it has fallen short sometimes when released.

I say this having bought SP10s, SP30s a SP31 and now 2 SP20s ... many have been under 'spec' when powered and running (yes 240v). The SP10s have been the most consistent solid miners I have ever purchased ... flat line at 1.4Ths with no deviation for months.

The SP20s clocked at full rate are also -10%, but to get best value you have to underclock (as this thread knows), and such easy clocking control is to their advantage in the GUI against others.

Sponds have compensated when machines came in under spec, and their customer service is second to none.

As ever, do your research, buy wisely and hash away.

i'm actually quite happy with the settings on SP20 at 1.7TH/s - it is slightly overclocked, bit of extra voltage and a bit more of a power draw but it is very capable of 1.7TH/s. When I set it to basic settings on the middle option, it sits at 1648GH/s.. doesn't take an awful lot to get it up... but it's right, they are exceptionally efficient when underclocked.

when I purchased I had 0, zip, nada, no, none, nil interest in running these at 1700 or 1600 or even 1500 gh.

 I had  hoped  to run 1400 at 900 watts  which would be .64 watt per gh.   


    I am running these at 1380-1400gh getting   800 watts which is about .57 watt per gh  temps and sound are manageable.

 So I don't complain personally. I only say for the builders sake listing them as a 1500gh machine that may overclock to 1700 would have been a better choice of advertisement.

I have 4 and may get 1 to 3 more by next week.

Balls to the wall with a monster 2000 watts PSU on 240V I can get 1600 GH/S. I might get more when the temp drops down to 0 here in Colorado.

oh i totally agree, don't get me wrong, as said, to get 1.7TH/s i've upped the voltage and overclocked it slightly.
In the SP20, I guess lots of people had been expecting something akin to the SP10 - which was an astounding miner in all senses and if it were a movie, would win all the oscars. I will be reverting my SP20 back to downclock today as i want to give it as much life as possible - and it's going to be going south to my free leccy unit sometime over the holiday period. The unit is not mine so I have to share some hashrate with the guy who owns it and when the SP31 arrives, i'll probably just set the SP20 to mine for him.
It is, depending on how you set it, probably the most efficient miner money can buy. Anyone know anything more efficient? looking forwards to seeing what my SP31 can do.

I am running 2 SP20's at 600W each at the wall and getting approximately 1.120 TH/s. That is equal to 0.53 J/Gh. I am using Corsair AX760i PSUs - one per SP20.

I intended to run these underclocked to use up "spare Amps". I have flat-rate power circuits with individual alarms which trigger once a certain amount of Amps are exceeded, and the fine grain control of the SP20 helps me fine tune my power consumption to be just under the limit.

[raskul]

downclocked again.

where I was running at 1.73TH/s using full power (drawing ~1200w), i have now limited to ~700w and getting 1.35TH/s
doing the calculations which matter... i'm now saving in excess of £41 per month in electric and only losing ~390GH/s.

1 x SP20
2 x S3+
total--psu--draw
1410w

@ 11.4p/kWh

=

£115 per month

And at current BTC price, at full power i'd be mining £31 worth of BTC more, so a saving in real terms of £10 per month and also, most likely, giving more life to the miner.

so you are getting under .53 watts

this is very interesting it would allow for me to run 9 sp20's


2 on each of my 3 evga's 1300 g2 = 6 x 600 3600 watts  and 6 x 1.12th  = 6.72th

2                 on my evga 1600 p2 = 2 x 600 1200 watts and 2 x 1.12th  = 2.24th

1            on my seasonic  1200 p  =  1 x 800 800 watts and 1 x 1.40 th =  1.4th

                                                           5600 watts               10.36th   rate of 0.54 watts a gh

going to look into this idea  raskul I may order some more soon

When it says +\- always expect the - value! I wonder what the SP35 is actually going to come in at, hopefully 3rd time is a charm and customers get the advertised 5.5 Thash. Hopefully no "slow corner" problems this time.

[cdjbolton]

Just a quick question, I was wondering if there was a guide anywere on how to overclock/underclock these machines, I cant seem to find a how to anywere but from reading through the threads everyones seems to know how to do it.

okay it is pretty easy if you are an old school miner and you did gpu's

this is a heavy duty under clock copy the settings and see if you do about 1210gh

[philipma1957]

Today I am taking under clock to the bottom for one reason> to see if 2 sp20's run solid and easy on a stud psu.

The psu is the evga 1600 p2.  the answer is piece of fucking cake.

two sp20s'  running connected to the stud evga 1600 p2  

seeing these numbers makes me want to see if I can do 1150 watts and 2300 gh.  with 2 on the evga 1600.

  If  I can this means  the evga 1300 may be able to run 2 sp20s'  !!!!!!




the psu evga 1600 p2


five sp20's and 2 s-3's under the moving blanket. note 3 s-3's to the far left using 1 evga 1300 g2




THE MONEY SHOT

1351 watts on the meter 2 sp20's pushing 2470gh !!!    1351 watts is a safe load for a 15 amp usa circuit !!  and a safe load for the 1600 watt evga p2

[judypug1956]

 Phil did you try for a lower number? I have a few evga 1300 g2 psu's   .  If you can run two sp20's on the 1300 I may buy 2.

I have 3 s-3 on my evga 1300 G2 they do 1470 gh at 1215 watts. Set to freq 243.75

If I can do 2 sp20's and get 2300 gh for 1215 watts that would be a huge improvement.

Yes I have gone a bit lower I am now doing 1266 watts and 2400gh on the evga 1600 p2

I have an issue these super low settings have made warning lights on my asic's.  It means I may have reached the lowest they can go.  I am waiting for the tech on the main thread to answer my question on this issue.

[daddyfatsax]

Whoa... Phil, I thought judypug was your second account.

[philipma1957]

Whoa... Phil, I thought judypug was your second account.

It is but I did not want to  do multiple posts .

 I am kind of excited as I think I may be able to run 2 of these on an evga 1300 g2 safely .  this really makes these a great upgrade.

For now two are stable at 1266 watts and about 2400gh

I will run this over night due to the warning on the asics  low freq .

I am a bit afraid to go lower until the sp tech says it is okay

No worries buddy. Just making sure I was not losing what is left of my mind.

I would like to get a few of these to replace some of my aging gear. It is just hard to justify the cost and shipping because I am going to be done mining before the summer hits. This summer was a bitch in Alabama and I am not sweating it out again. 

[DevonMiner]

Is this when the ASICS show yellow in color? A few of mine are, but the units are stable.

yes if you go too high for temps you get yellow

if you go too low for freq you get yellow.

now i really hope this is not a problem as two sp20's are on the one evga 1600 p2  at 1266 watts.  It is an easy fix to go up to 1350 watts as the evga 1600 p2 and my 15 amp usa power circuit can do 1440 watts 24/7/365

but if it is a problem my hope to run 2 on an evga 1300 g2 will be done.  I am going to proceed slowly with the next test.
