Topic: [Guide] Dogie's Comprehensive SpondooliesTech SP35 Setup [HD] (Read 16153 times)

how do you get wifi working on these ... I found links saying the Edimax EW-7711USn and EW-7718Un work .  So I bought the 7711 model and cannot get it to work ... plugged it in ... waited 2 minutes ... rebooted ... waited a few minutes ... shut down ... powered on ... nothing on the Wifi link shows up.

thoughts?

I don't know if I've ever seen an SP35 one or if it uses the generic SP3X. Someone else might know.

Hi all,
i have a SP35 and i need the sd recovery image file to reset it, the official site is down does someone know where to download it ?
thanks !

I'm not sure if it will actually let you run a half SP35.


Comparability will be based off the gold finger pin interface; you'll have to find one with the same otherwise there's no way around it. The original PSU should be readily available at a cost for new, and possible used for cheaper.

Good day I need your help, my spondoolies sp35 has a psu damaged, I need to know how to configure it to work with one psu, as is showing me the stats asic and constantly reset:

12/08 11: 24: 17: Hash rate too low !!!!

The other solution I need is to replace the damaged psu with a one generic, in my country (Venezuela) I have access to buy a model psu HP DPS-1200FB server power supply, I need to know if it is compatible with my yukon sp35 or if you can somehow adapt.

could you tell me if there is another psu compatible with my yukon sp35?

thanks and sorry for the trouble.

We wish you all the best in your new venture and will help with any data or experience that we have.

thank you SO much. this is DEFINITELY some good pointers. i will be looking into this. my electric rates are 4¢ kWh during the summer and 3¢ kWh during the winter. so my profits will be a little better than your estimate we also have a roof for our rates. no more than 3000.00 a month

b1naryn1ghtmar3, Welcome to the Forum.

When we were first planning our farm we did a lot of research on power distribution and Heat / Cooling and our happy to share our findings with you.

Power Distribution:
22 units @ 3,600watts = approx 79,200 (+/- 10% to 12% leakage) watts just for SP-35's (H-$7.92, D-$190.08, W-$1,330.56, M-$5,702.40, A-$69,379.20 US @ .10 ($/kWh)
(Cooling not including in this calculation)

The "Heavy Power" standard for the United States is 3-phase voltages of 208, 220, 230, 440, 460 480
79 Kw Line to Line voltage for 220 with power factor of 1 is approx. 207.321 Amps
79 Kw Line to Line voltage for 480 with power factor of 1 is approx. 95.0222 Amps
 (Note: Calculation assistance http://www.rapidtables.com/calc/electric/KW_to_Amp_Calculator.htm)


PDU RESEARCH: We narrowed it down to 3 companies Raritan.com, Tripplite.com and APC.com (now a Schneider Electric Company).  We went with Raritan PX family of intelligent iPDUs for the individual outlet switching, monitoring and high amperage per unit. They are a little expensive but we have found that they more than paid for themselves with the expanded flexibility.

HUBS: as for your question on Hubs; I would not use a "HUB" it is a broadcast device all communication to all ports.  A "Switch" allows communication to be directed on a port-by-port basis.  The Sp-35's use 10/100mbs Ethernet so make sure so make sure your switch can handle 10/100/1000.  We went with http://www.BROCADE.com switches and routers (note: we had them already and they are very expensive but I would buy them again if we were starting this project from scratch). 

COOLING: We have found setting COLD/HOT isle worked best for us.  Cold Isle is referencing "Conditioned Air" in the front of SP-35 (estimate approx. 93dB) and Hot Isle is the exhaust heat out of the back of the unit (estimate approx 82 dB).  We Opted for Air & Evap. Cooling in Louisville, Ky. (Mid-West of the US).  Another option working into the Fall/Winter is to Evacuate the Hot Side back into the office (People Conditioned Air) or just Out-Side to the environment).  We opted for "Containment or Container" based Cold/Hot instead of Data Center philosophy of cool the hot air and blow it up (Loop or Circle or Air).

INTERNET BANDWIDTH: We have a 100/100mb Fiber Internet Connection and the "Server Farm" is only a small fraction of the UP/Down Load connection, most internet traffic is "East/West" (Server to Server), "North" is Internet or Crypto Authentication and "South" is to the secure servers.  With 22 Sp-35's a Low bandwidth connection ranging of 10/1, 15/2, 35/5 or 50/5 connect will be more than plenty.  I never scrimp on "Bandwidth up or down", I can always use more.  [/li][/list]

NOTE: There are a number of Tools out in the Free or Open Source pool that will help you SSH, Monitor, Control or Adjust the Sp-35's in your stable.

NOTE 2: Our next generation is/will be Containerized @ 1.2Mw - 1.4Mw each and placed approx 80'-100' underground for cooling.  Heat evacuation is one of our biggest issues/concerns.

thats what im asking for... i need help! i have hid a small mining op for a while now and i KNOW how much heat that thing puts off... its ridiculous. so im asking for some help and some pointers to set this up.

I don't think you realize how much electricity were talking about.    You really should get an electrician. 

No one 36 inch unit will not be enough.   How did you get these 22 units?    I think you underestimate how much heat they put out and how much electricity you need.

ok but i need some specifics, i can get the racks pretty easy, that isnt a problem but the PDU and wiring and all of that i would need some help with. like i said, if you are willing to point me in the right direction i would be willing to kick you some coin. currently i have a small mining op (20 TH/s) that doesnt require much and for me up upgrade like this, i want to do it right as to not have too much of an issue

the room that all of this will be in, is a 3000 square foot room. i currently have 1 36" Evaporative Cooler Direct Drive 3 Speed, would you think this would be enough? if not, i can get 1 or 2 more. i am currently looking for good PDUs but cannot find any. help please?

~115KW for 22 SP35s, so need either a good dump to ambient or decent evaporative. Racks / tables don't matter, get whatever is cheap but isn't going to fall apart. I'm sure you could find some good Steel and MDF racks for like $50 and spray treat the wood.

Internet requirements for mining are minimal, both bandwidth and speed requirements.

Cooling kinda depends on what they are in as far as placement I'm unsure what ambiant conditions, place, if evap cooling is possible etc. 

On "towers" if you mean a server rack I would save the money and use something else, unless you find a good deal used.  Just can save a lot of money there.  On internet as long as it is constant yes they do not take much internet speed just needs to be reliable (IE no dropping packets, no downtime, etc).

Hubs again I would see what you can get used if your talking 22 miners that is quite a hub.  If you can find used again save good amount of money.

One thing you don't mention is wiring and PDU's.   Make sure to save money for this.  Also make sure you have enough power 22 sp35's is a LOT of power.

ok, i have a VERY serious question here... i have 22 SP35s and i would like to know how much heat would they all give off so i can figure out what kind of cooling i would need. also, anyone know of any good towers? i would like to set like 3 or 4 of these per tower at minimum. also would 1GBPS fiber lines work for this amount of miners? if so, know of any good hubs? i want to be able to set these up soon and have 20k left to spend on everything to get these running... im making a price shopping list

please reply to this or message me if you can help

Can anyone provide a table or graph of how 'ASIC Voltage Limit' affects power draw and hashrate of the SP35 (the SP31 numbers will do as well)? Spondoolies, do you have that data available?

That would help owners determine the best settings to maximize profit. Those with high electricity costs may find that undervolting provides the highest net profit in today's mining environment.

For example, here are some values I measured for an SP20:

1315GH/s
maximum voltage limit: 0.67V
power: 765W

1250GH
max: 0.66
power: 695W

1200GH
max: 0.65
power: 640W

1137GH
max: 0.64
power: 577W

1085GH
max: 0.63
power: 534W

Excellent, thank you.

No problem powering the SP35 at 120VAC.
No problem hashing at that voltage as well but performance will be low due to the 800W limitation.

This was tested (for example, FCC tests were done on 120VAC and 800W).

When not hashing power consumption is very low. the management board consumes less than 10W and the fans can consume up to 65W if running @100%. Fans will only run at this speed until SW is loaded. At this point SW will reduce fan speed and fans consumption will drop to few watts.

I've poked him, should be along shortly.

Any update on this?

Yes, we'll check power draw on Sunday.
