To reach anywhere near max performance (1.7TH +/- 10%) they need to be somewhere very cool (sub 10°C) and have the fans running at min 80 speed, just make sure you can keep them somewhere where noise isn't an issue

You can run them at 1.5TH with 40-50% fans at 20-25°C ambient and they are tolerable in say a separate room.

Or you can replace the fans and underclock them and keep them under your bed

That is okay if power and cooling are free run them in  the 1500gh to 1600gh hash rate.

Use fan  speed 80 to 100. 

  please understand that above 1600 gh needs a very cold room that is 50f or 10c  fans at 80 to 100

and a good psu the evga 1300g2 .

Thanks for this great reply.  I'm luckily in a place where power and cooling are being provided for free for the next year, so I'm not sure I'm going to underclock this first batch.

you can do 3 sp20's with 2 evga 1300 g2's  

you need to run the sp20's in the 1200gh area.  

if you are willing to run in the 1150-1250 speed.
other decent psu is a 750 watt corsair rm

sidehack has some hp 2000 watt servers  they can do 2 at 1350 gh

or 3 at 1025gh


Biffa is correct about the superflower leadex gold 1300w

If you host at our datacenter, we can supply customized PSUs suitable for the SP20.

We mod server power supplies by soldering PCIE cables onto their 12V rails. The server PSUs, are over 90% efficient, and are designed for continuous use. We can supply one PSU suitable for an SP20 for $100.

See our website here: http://www.asicspace.com/

SuperFlower Leadex GOLD 1300W is the same PSU as the EVGA

I've read some good things about the EVGA 1300G2 PSUs for these.  I'm stepping up from putz around mining to some(5) of these jackson s20 boxes.  Any other good PSU options? 

Your draw will depend on your power supply, it's efficiency and a little bit on your specific unit.

YMMV but here are my settings:

Start Voltage = 0.665
Max Voltage: 0.67
Max Watts = 200
Fan Speed = 50%

There is some variance per unit but these are the settings I start with and adjust in 5mV increments from there until I get in the neighborhood of 1.3TH/s plus or minus a little bit. For my units, these settings I start with usually put me in the neighborhood of 1.3TH/s.

Once I do that, I adjust fan speed down from 80% until I get to an area where a majority of the ASIC temps can still stay around 85C. Two or three will usually be a little bit higher, say around 100C.

Can you post your settings;  I'm drawing just over 900w

I used the GB price of $500 although it's MOQ of 2. One should be able to find a buddy somewhere around to co-order one of these packs and get the nice price.
If you do have to order something, why don't you order it for somebody else and get some BTC instead. How much do you have to spend?

Underclock the units. I get 1.3TH/s with an at the wall draw of 800 watts on my bronze power supplies.

Couple that with 0.06 cents per KWh winter power costs and the fact that I already have power supplies laying around and purchasing these units makes total sense in my situation.

Besides, this is just a hobby for me. My goal is to provide hash power and just not lose my shirt doing it.

was gonna say your price was to low my figures were 544 usd (to usa) on the above...but just looked the xmas price page seems to be gone it is
back at $659.00 w/o shipping again it seems

www.spondoolies-tech.com

what makes it even worse is your power consumption is not 500 watts as your calc shows but but 1200 watts  according to their spec sheet

and you have to buy a PSU (1250w?) I think to run this (unless you have one)

http://www.spondoolies-tech.com/products/holiday-special-sp20-jackson-shipping-from-stock

it is too bad I owe these folks a purchase of some kiind for a refund they gave me (they did not need to ...offered I accepted) but man at 15c kwh
around here and on top of that a 100 amp service (have 1350w Titan) could not probably swing the dual electric at this time
even it if did make sense (estimate is 2.5K to upgrade to 200 amp service) so still fence sitting

still waiting maybe after the first of the year....but dang tough to buy equip from anyone vs buyng BTC these days ..even
thou imho www.spondoolies-tech.com is going way beyond the call of duty on price etc imho...but everyone in BTC land is trapped
it seems by $320 BTC price and such ..and heck it may even go lower...(probably not what they expected when they farmed in their price per unit costs when the
sp20 was designed around first of the year or whatever) so anyway they can only go so low imho

tough climate out there in the BTC universe


edit: additional

well for those interested Roadstress's Group Buy link on the spondoolies page for 1000 usd for two sp20's still seems to be valid
for those in better circumstances elec/$$$ and such then myself at this time

Here is mine:

https://tradeblock.com/mining/a/gN3YBAsfXd7vNF9trZdjZK

SP20 bought now is $500 inc. shipping. some might pay VAT and some might now.
Downclock it a bit to get better power and then find a place with cheaper power.

Your costings are wrong.

SP20 - $659
1.7TH/s
Shipping - $119
Power Supply $200 (decent one)
Total $978

I just want to know how its done. Even lowering the price to $500 doesn't give you your return. I'm just trying to be more green. And my girlfriend has me on this kick of powering off everything. The more miners sold, the more electricity and larger electric foot print the mining community will have. Maybe I will go green one day, try to do my part in making our only planet livable for our grandchildren. But trying to plug in some numbers, seeing how nothing gives you anything back for what you pay for, why do it? Please tell me I've made an error somewhere. And not some $20 error. I want to justify in my head on the electricity use, so maybe I can bring that back to my girlfriend and she'll start to agree. All she sees is a bunch of electricity sucking hardware all over and a high electric bill. And of course a tripped breaker when she wants to dry her hair or vacuum. What is wrong with the below screen grab? Is it really all about free electricity?

https://tradeblock.com/mining/a/f56Tst2NSu7ARxAcen6VCS

That's all your gonna get out of it. Lucky you got 1.9 btc.

Even with free electricity its almost impossible to break even on new hardware, hence selling from stock. If it could make you a little money on the side they would be out of stock already. Manufacturer's have a real hard time lowering prices to a drop bottom price because they've had it so good lately and are use to the premium prices. Doesn't matter if it is 10TH/s rig or 10GH/s rig. Then on some of the home products you still need to buy additional hardware like a power supply. And for the users that bought hardware anyway, they may have purchased on coin they made with their current setup and think they'll still make more after BTC rises. Unlikely though. I bought a couple of the "cheaper" brands that are cooled by water with my dad basically for fun, and sometimes they work great and sometimes they don't. The only rig that has been solid as a rock is my SP10, which will be turning off very soon since I can't run it at my house and it isn't making enough to pay for co-location costs. I'll have 2 SP10's for sale probably pretty soon. I need my garage for my cars and I really can't run that at home because of the noise.

Happy New Year!

This is a joke? Hes ..... opposite of Christian. I hate it when ppl keep forcing their religion shit on others without knowing shit.

I witness ppl say merry Christmas to a clearly Muslim couple. Fcking grind my gear.
