I'm going to order the 3 x SP20 bundle for $1200. One question is how do you set one up to run at 1.6 TH? I have cheap electricity, no worries there. I would like step-by-step guide, please no link to Dogie's guide for noobs, his guides are a waste my time.
It seems I have to fiddle with voltage and watts and what not, very confusing. How do you set it up for 1.6 TH each unit? I have a bunch of 750 W Corsair modular PSUs. TIA.
2x 750 watt psu's cold room 50f or colder or 10c go to settings page Fan Speed--------------------------------------------- 80, 90,100 test each speed as 80 or 90 can work better then 100 , Set your starting voltage no more then 10 mv under your stable working voltage (from ASIC stats page) Start Volts Unit 1(0.58-0.80)-------------------------0.69 Start Volts Unit 2(0.58-0.80)-------------------------0.69 Start Volts Unit 3(0.58-0.80)-------------------------0.69 Start Volts Unit 4(0.58-0.80)-------------------------0.69 Set your Maximum voltage limit to 0.790 for unlimited or less for under-voltage Voltage Limit (0.580-0.790)------------------------------------------------------------------0.79 Set PSU power. Max PSU Power Unit 1 (70W - 288W)-------------------250 watts Max PSU Power Unit 2 (70W - 288W)-------------------250 watts if it works well leave it alone or crank it up to 288 after a 1 hour test. Max PSU Power Unit 3 (70W - 288W)-------------------250 watts Max PSU Power Unit 4 (70W - 288W)-------------------250 watts Restart miner if rate below------------------------------------1200 FPGA serial speed (0=10MB, 1=5MB, 2=2.5MB) ExtraFlag: add numbers: 1:no-scaling 2:extranonce.subscribe 4:no-debug 8:alt-bistword Hostname, empty for default (needs reboot) Save Thanks for the comprehensive information! That's what I was looking for! Dogie can learn a thing or two from Phillipma. |

Is it possible to change to PSU efficiency in the formula that calculates "wall watts" ?
I know the preset one is 0.90, but mine are 0.93
If I can update that number in the firmware, I'd have more correct readouts.

0.93 is based on the official test of one unit, but of course can vary a little in reality and with PSU age. Do an interesting experiment: Using a KillaWatt meter test the actual draw. Compare that to SP20 software reported value. If we know the reference preset is .9 it would mean I would hope your KillaWatt draw would be less than the number advertised. |

I do these tests constantly and depending on the PSU and(!) the actual percentage of it's maximum power draw it is very close to it.
depending on the PSU the efficiency can drop a lot if utilized under 25%.
e.g. with a 2000W PSU it's always smarter to run 2 SP20 (up to 1600 GH)

I did all that for my PSUs, that's how I came up with the 0.93 value. Now all I need is to be able to update it in the the firmware, so its' calculations are correct. |

I am wondering if it would be possible to run an SP-20 with a single CX-750 with lowered voltage settings any thoughts what the settings would be or if it's feasible?

yes I run one on a 750 watt seasonic try FAN auto -------- you need newer firmware like 2.6.7 or higher if you have older firmware use 20 for the fan. 0.61 volts 0.61 0.61 0.61 0.615 max volts 130 watts 130 watts 130 watts 130 watts should get 1025 gh at 540 watts if it works for a few hours you can do a bump to 0.615 0.615 0.615 0.615 0.619 135 watts 135 watt 135 watts 135 watts if it works for a few hours you can bump again 0.621 0.621 0.621 0.621 0.626 140 watts 140 watts 140 watts 140 watts if it works for a few hours you can bump again 0.626 0.626 0.626 0.626 0.631 145 watts 145 145 145 maybe one more bump 0.631 0.631 0.631 0.631 0.636 150 watts 150 watts 150 watts 150 watts this is 600 / .87 = 690 watts I consider this to be iffy on a 750 watt psu. here is my sp20 on a seasonic 750 watt plat psu watts at wall are 606  settings watts are 140  the bigger images are here http://imageshack.com/a/img538/2984/ba05YN.pnghttp://imageshack.com/a/img913/5220/U0XXpy.png |

most of my sp20's are on 750's or 850's.. depending on how nice the chips are, you will get between 1150 and 1280 at ~650w |

they look much better then mine do. I will switch the one using the seasonic. is your tmp the celsius reading 9c to 14 c? |

yes temps are C. as you can see, some of the sp20 perform much better then others as I let the software find the best hash for the voltage allowed in. |

Thanks Phil that's exactly what i was looking for should be able to run three off a single 20 amp dedicated circuit. I know it's pushing it but i'll fiddle with it and the kill-a-watt. You really have been doing great work on the SP-20's and S-5's and I greatly appreciate all you efforts on behalf of the community.
