But if you want to test the SP20 with the new extronance bug fix by all means go ahead, you would be doing us all a favour by testing it. Just post the results so we can have a look and be very careful. Backup the old flash build and the cgminer twice. Once on the machine and once locally. If you're unsure of what you're doing stop...I've seen alot of stuff break over the years from bad flashing and other screwups without the tech guy making a backup to re-flash. It's an $800 mistake if it goes wrong.
By only replacing cgminer binary you can not brick or damage your miner. It is now a firmware update, only the cgminer binary (one executable file) with a newer one. Nevertheless it is true that one should be careful when doing manual modifications on miners. This binary was provided by ckolivas (thanks again, Con) and is working flawlessly: https://www.nicehash.com/index.jsp?p=miners&a=1&addr=1JFUoyUSnLcrMjfq3hEBFsNLhLk5QY3vQR+1 i've been waiting to see if Zvi would implement the extranonce.sub but I can't consider it for my SP-Tech miners from a nicehash branch that hasn't been fully tested.
We've already asked Zvi to include our very small patch into their firmware, hopefully they'll include it soon. no just point your miners at nicehash and enjoy the 3x to 7x rental rate while it lasts. I got .67 btc in 25 hours. my miners (7th) should earn about .1btc in that time frame.
True, extranonce.subscribe is not absolutely required to mine on NiceHash/WestHash, you can just point your miners to our stratum servers. However, if you have a fast miner (anything > 1TH) mining with extranonce.subscribe patched cgminer gives you a bit better payouts since your hashrate is completely stable - it doesn't fluctuate when orders changes on nicehash/westhash - no disconnects from the stratum. It's only a matter of a few percents in terms of profitability, but sometimes every percent counts. I am curious as to what kind of game you are playing? What is a basis for much higher payouts? Explain, otherwise I will consider it a long con or a simple pyramid scheme.  They aren't doing anything, all they are doing is leasing their rigs out. The people who are leasing the rigs, choose what to pay to lease the rigs and what coin to mine. All the hardware person has to do is pick a reasonable fee to charge and make sure their miner stays online for the duration of the hire period. The coin being mined may be a long con, or a simple pyramid scheme or just a POS coin, but thats the choice/risk of the person leasing the rig. This has been going on for a long time in the alt-coin world. |

Do you need the extranonce thing for betarigs or just for nicehash?

Phil - Thanks for this thread! My SP20 arrives on Monday and I am trying to decide how I should power it. My goal is the most GH I can squeeze out of a single PSU (I am almost out of space is my issue). My options for the single PSU are: Corsair 1200AXi, LEPA 1600, and Silverstone 1500. These are all PSU I have left over from my GPU farming days. I am assuming since the Silverstone only has 25 AMP rails it is out. The LEPA has 4 x 30 AMP rails, and the Corsair is a single rail. I am leaning towards the Corsair, but will it provide more than the LEPA? If anyone has some thoughts on this let me know!
Edit: I do not care about power consumption - just GH!
use the corsair. run thesp in the 1400gh range (yeah I know not 1700) and add a s-3 to the corsair run that at freq 237-243 you get 1400gh + 475 gh = 1875gh I have the 5 of them and to run it to the max is like taking my little Kia Forte and driving down to Atlanic City to play some craps. It is a 60 mile ride Almost all highway. Now my Kia Can go 120mph on the speedometer. When I go down to AC I just drive at 75mph it is an easy drive. I don't try to run the car at 120 or even 110 mph. Even if I have free gas. These machines run really well at the 1350-1410gh mark. The amount of extra power to go higher could be spent on an s-3 on the same psu. It is easy to get just about 1800gh with 1 sp20 and 1 s-3 on your corsair. It will be hard to get 1700 alone with the sp20 and your corsair. I figure you can do 100 to 200gh more blending the 2 on the corsair rather then maxing the 1 sp20 ( both setups will use same power in watts around 1200-1300) Isn't the Corsair multi-rail but you can select some virtual “single rail” or “multi-rail” software modes? I remember people had trouble with them on KnC gear. I'd stick with the LEPA |

Half of my 10x SP30s dont work very well.
I dont believe they can work for many months.
How can you ROI in such investment?
Can you be a bit more specific? Also some insight into the environment they are in? |

Somehow, my backyard view seems nicer  No doubt about it But raskul has some of the most quiet neighbors one can find  spiccioli Yeah and people are dying to move into that neighbourhood .... |

so under-clocking just a little lower then 1266 watts for 2 sp20's would allow me to run all those evga's with 2sp20 each.
so I know the sp30/31 can do lower freq then 750 can these sp20's go as low ? Is this under clock safe?
I have a couple of 1300W EVGA PSUs too. If you can manage to run 2 SP20s on one PSU I would consider getting 2 so keep us updated. yeah it is a piece of cake on the more costly 1600 p2 I am going to run the 1600 p2 at the 1266 watt 2400gh and low asic freq overnight. if I am good to go I will test the 1600 p2 at a lower setting from 7am to 7pm tomorrow. if it still works I will then do the 1300 g2 with 2 sp20's My EVGA 1300 just died after 4 days with a SP20. Luckily the SP20 made it ok. Was it an older model? There was a recall on the 1300G2 when they first came out. http://www.evga.com/articles/00803/ |

Can someone do a sound meter check on their SP20 in their home? Not in a garage or warehouse? I'm trying to figure out the acoustic situation they will bring down on me and figuring ways to avoid that if I bite. Here's one of my AntMiner C1's hashing 1005TH/s. I actually have two in the same room and don't notice they are there, but of course rather have Spondoolie's if the prices are right. Thanks. I was about a foot away or less when doing this measurement.   Thats at 80% fan. |

I don't need to do a temp test from the window, I can SEE it lol:
You live in a graveyard?  Those miners can be loud... careful they don't raise the dead. *Careful they don't mask the sound of the dead being raised. I'll be overclocking it with two CX750's as long as it's not too noisy. Judging from the snowfall out there, the holiday season should be perfect for some mining to heat up everything. My old friend, I am sorry in advance  A minor underclock and you should be okay to lower the 80% fan down.  Not even if I point it at the frigid air outside? It's been some time since I mined after the days of FPGA's and GPU's, so I'm not too sure what to expect here. Its a 30W fan at 100%, compared to your usual fan of ~2W. This is big boy mining now I am not an engineer, but I would venture to say that some of the noise would be shape and placement of the holes the air is moving thru. The fan sounds pretty much like that outside of the case as well  |

Going to ask this one is giving me hard time, yellow number + i see the hz gets blue, anyone know why it is ? and were its located in the box?
i'm going to put this out there now: if it's hashing at a good rate, don't look too deeply into the ASIC stats. the SP31 i received today has a bunch of low volt ASICS, but it's still performing at 4.7TH/s... if i wanted to, I could gradually up the voltages and get them to sit green but as far as i'm concerned, there is no need - it's performing 200TH/s above advertised spec. i'm presuming it's probably just the ambient temperature in which i'm running it. i wouldn't be overly concerned if I were you, however, I know Phil likes to go in depth, so he may be able to assist if you really want to get deep into the rabbit hole. yes mines at 4.741TH so I'm not even going to look at it for a while  have you estimated when we'll need to downclock? (i clearly have nothing better to do on a thursday night after watch some crap football) Mines not in the UK so will be a different date to yours |

BTW got a couple of new fans to test |

aw thanks dude.
i got the best b'day present ever too... more later.
free electricity? better than that.  and it'll turn out to be rather expensive. Mail order bride? |

I think the overheating issues rumour is based on the farm fire in Thailand. Very convenient for competitors and their shills to use. I even saw one thread where the guy went off on one saying it was SP's datacenter where all the customer rigs are located. |

Does anyone have any stats on how loud a SP31 is at high, medium, and low settings?
I'm considering getting a SP35, but SP10s were a bit too loud for my taste, so I'm hoping a SP31 / SP35 will be easier on the ears due to the larger fans.
I don't even mind running it at a lower speed if the sound is more bearable.
SP30/31/35s are not as loud as the SP10, but they're not quiet by any means. If you're using 120V, the power supply fans will have to run at higher RPMs which makes them louder. On 220V, they may be more bearable. Due to the small size and high speed of the SP10 fans, the noise the SP10 makes is relatively high-pitched and annoying; the SP30s' noise is lower in frequency and more bearable in tone. You can run these on 110/120v? I remember reading that they required 220/240v... Can somebody please confirm? Thank you SP31 can run on 110/120V but SP35 is a 208V or above only |

Yes but whats interesting here is the requirement is more of a case fan than of a heatsink fan or radiator fan, because the fan isn't facing a lot of restriction its just pulling air through the case and out the end. They use a YS Tech FD1238UB Waterproof fan.  CFM is only 212 but its got a very mechanical noise to it. I've been trying other fans with less noise but have yet to beat it for cooling. Got a few more fans coming in the next few days to test though. You probably have a lot more sitting on shelves |

No one complains when we get back to back blocks...

That would just be silly So is complaining about bad luck. M No that's just human nature, complaining about good luck would be psychopathic |

I hope that whatever he paid for the account, gusti the second feels that he has had a good ROI All it takes is one sucker to buy a unit  |

so a shout out to the legends testing please try the killer delta fan and over clock the unit. I would love to see the user's show the over clock potential. maybe a better fan for the under clock guy like my self. for that matter maybe someone would use the super powerful monster delta fan for over clock . it moves 25 percent more air then the stock fan. mr teal is really handy with gear. this is the fastest fan around. would be the best for over clocking maybe?? http://www.newegg.com/Product/Product.aspx?Item=N82E16835213001&cm_re=delta_fan_120mm-_-35-213-001-_-ProductDepending the application, the 210CFM QFR1212GHE will actually move more air than the 240CFM AFB1212GHE. Like a lot of fans tailored to moving air without restriction they have a shelf on their pressure-airflow curve, and once you get to around 0.5"H20 they quickly lose any advantage they have over a fan designed to really push air. The downside is the QFR is louder, spins faster and uses more power. No what you want is the PFC1212DE-PWM or PFB1212UHE-F00 (if you want non PWM without a connector) Dimensions: 120 x 120 x 38 mm Power Leads Length: 300 mm Rated Voltage: 12 V DC Operating Voltage: 8.0 to 13.2 V DC Input Current: 4.00 A Input Power: 48.00 W Speed: 7160 RPM Max. Airflow: 252.85 CFM 7.160 m^3/min Max. Air Pressure: 1.412 IN H2O 35.877 mmH2O Noise: 66.5 dBA Problem with the SP20 is it uses a custom header plug onto the controller card. Shouldn't be a problem for you chaps handy with a soldering iron though. |
