Topic: Unofficial Spondoolies SP20 thread - page 65. (Read 126204 times)

may i ask where in the world?

Ordered Sunday and shipped Tuesday! Thx SP-T. Looking forward to Thursday, building 14awg harness now!

I think the settings I have shown above should be OK for you as long as you are running off a 220v supply - you can see in the screen grab the specific settings, they are all customisable.

Thanks for the report. Huh, don't know about tweaking (I have no experiences with Spondoolies miners) ... are you trying to say that there are any individual settings that can be tweaked in accordance with configured asic wattage cap? Any other tweaks that an "undewolter" has to be aware of?

^done. if you find it useful, please order via my affiliate link, in my sig. thanks.

let me do that for you.

SETTING ASIC WATTAGE CAP to 245 x 4 = 980W capped.

...screenshots to follow

... initiated at 1.459TH/s and ramping up the way...
... passed 1.5TH/s in under 1 minute.

settling down to 1.53TH/s.. then up to 1.56TH/s

seems to settle at 1.56TH/s+
would you like me to tweek any individual settings?

philipma1957, could you please test what kind of hash rate delivers a single SP20 when is configured to consume just below 1kw, say approx. 990W at wall?

the question you need to ask yourself Phil.

which is more efficient?

Fill up on SP20's 

third one has arrived and is mining.

fourth to arrive on Thurs.

I have reached  A funny problem.  do I sell every s-3 and go for 6 sp20's

rather then running  4 sp20's and   6 s-3's
 

you have a choice of watt settings.  70 to 288

288 is max and will do more then 1700 maybe 1750

problem with  this 288 x 4 = or 1152 watts

very few pcie wires run well at that setting


evga 1300 and evga 1600 can do 250 all day all night for months.  I have done it with them.

I have no other psu that will do that with stock wires.

So if you want max setting of 288 to get your 1750 you are really pushing the machine

Like I said it is their marketing decision.  

I would  say this is a 1600gh machine and with  a carefull overclock it does 1725.

Since I set my machine at 180 watts x 4 = 720 draw or 750 at kwatt meter  vs 288 x 4 = 1152 draw or 1300 at kwatt meter.

  I don't care a single bit about the difficulty to reach max gh.

I found this to be very true with gpus back in the day:

  you may get .5gh with a hd7970 and use 170 watts

crank it to the max you get .66gh and use 300 watts.

Hard on the gear hard on your ears . ( < That reads  like porn not meant to)

So I underclock and I am happy.  Those looking to squeeze everything out of this machine will need really good pcie wires really good psu's and will be maxed under 1800gh for sure.

no, underclocked it runs at 1.4TH/s

@ ~< 750w

so stock it is only working at 1.4 TH/S not 1.7 TH/S as they listed ?

second one in. third one comes today.

yeah the only thing I see wrong with this gear is the marketing should list it as a 1600gh miner with possible overclock to 1700

I got mine to 1710 with fan on 100 and an evga 1600 p2 psu  it sucks a lot of power doing this.

Ran pretty hot. my watts per gh drop from .55-56 to .71-72  At that point for power the s-3's are competitive .

For me I knew I was going to clock it lower and did not care that it struggles to go to 1710.  my watt settings are at 181 vs 288 and the gear runs really well.

note temps this with garage door closed





all numbers are good  safe etc

with the fan at 90, you wouldn't want it in your home -  it would be OK for an outhouse, or garage.
with fans at 40, I have mine in the room next to my living room and although i can hear it, it is quieter than the traffic going past outside, and the tv drowns it out easily.

IMHO, not too bad and cheaper than running my 800w oil heater

is it noisy?

I think the limit is on the pcie power connectors, they can only handle so much in the socket and cable

it'd be good to see instructions to overclock too... perhaps there is a modification, whether in software or in the unit that we can do, to raise the wattage cap from 288w?

Maybe the OP should rename this thread to "Underclocking the SP20 for fun and profit". Then it would be more obvious for the tl;dr crowd

What is cheap? (PM-ed you...)

hi
i ordered sp20 at friday
it was picked up by dhl at monday
it has arrived today

i have set 0.63 0.63 0.65 0.65   0.67 max 175 175 175 175
it hashes at 1300GH/sec and consumes 720W

only one figure is yellow
should i tweak settings a little bit or i got max btc-power cost now ? (0.18c/kwH)
