2 SP20s @ $1000 + shipping heading my way using OGNasty as escrow. Thanks, teeGUMES!

Thanks emdje, much appreciated. Sent you some beer money!  Have you got your replacement chip back on the board? |

Sweet, thanks for the updated cgminer emdje. Are you planning on releasing a new image with the latest updates? I suck at linux command line.

My S4 Is running at 0.760V 256.25Mhz here is a test run I did. 2 chips cant handle the frequency but they work fine when running stock frequency and voltage. 0.760V might be a bit high for that frequency but it gets them chips stable. Also don' t mind the difficulty, I am renting it out at the moment and the renter has a crazy pool. Also running one of the fans on my own controller, testing my controller. Want to run all the fans on my own controller. Don' t like the noise. The temps are steady and will hardly ever change more than a few degrees. I figure this is okay?  Your temps are great considering the overclock. What power supply are you using? Also, which combination of smit's firmware are you using? |

What I'd like to see added to the SP20's firmware is the ability to adjust the PSU efficiency multiplier. Using a Titanium rated PSU, I'm about 50-60w below the reported "wall watts" when measured with a kill-a-watt. No biggie, but it would be nice.

This thread is actually in the wrong forum actually.
I'm not talking out of my ass dummy , if you have your 30Amp breakers properly wired to a modern panel you can run them close to 90% load with no problems
some people even run then 100% load. You would expect the breakers to be slightly warm with continous load but
if you are not sure on your wiring get an inspector or run them below max better safe than sorry.
If my wires were warm to touch I would definitely not run that much load your setup is a disaster waiting to happen.
and read my post again I never said i run at 100% load , thats stupid
 Yes, you're right and everyone else is wrong. Carry on, and please post pictures when the weakest link in your circuit fails. says the guy running his circuits at 100% load What's your point? I've run them at 100% in the past, and would still do it temporarily in a pinch. Now they're all running at 80%, no more, no less. I wouldn't advise others to do it, unless they knew what they were doing and had built the circuits themselves. Again, only temporarily. The bullshit you're spouting is dangerous advice for someone who doesn't understand electricity. Are you so pig headed that you can't admit your advise is bad? No one should run their circuits full load continuously. |

Time to abandon ship, folks. p2pool and kano's pool will happily accept you with open (honest) arms!

I do not want to review this item. Let some one newer do a review.
I'd be happy to do a review with lots of info, pics, vids and statistics. I know you would do a good job. Thank you Sir. I aslo will be more than happy to do a review if needed.  Prelude if you get one I can also help!  That could be cool, since you live close we could each do a review of it. Get 2 opinions out of 1 rig. You bring the beer I'll bring the electricity! Yeah a tag-team from north of the border eh! Both of these guys would do a good job. We do not get a lot of Canadian reviewers. I have my hands full this spring as the winter cold seems to have done damage to my home and I will be dealing with a contractor or two. Always fun (not) Damn, that sucks.  What happened to your house? |

One circuit is breaker is marked "mill" and the other "lathe". I have always just kept the breakers turned off.
Both mill and lathe have double 20A breakers, so how many watts does that give me on each circuit? 9600?
Since I am not use to working with 240v and have appreciation for the danger, I will have an electrician hook
it all up for me.
Thanks,
Tom
240*20*0.8 = 3,840. So you can safely run 3,840W of gear 24/7 on your 20A@240V circuit assuming that the wiring in the walls is of the required gauge. F that I max out my 30 amp breakers at 6800 watts or so , the cables are not even warm that's 80% rule is really meant for 20 to 15 amp wiring that is far far inferior to 30 amp wiring. 30 amp cables are almost a half inch thing you can max them out at 90% load pretty safely Please don't talk out of your ass. The 80% rule applies to all wiring. It's a safety code, and it shouldn't be ignored. That being said, I have run 30A 240V circuits at 100% load for months at a time. Why? Because I wired everything myself and I know I used quality hardware everywhere with everything installed properly. While the wire gets warm during the hotter summer days, it's not an issue. The real issue is with the breaker, going over 24A on it for extended periods will cause premature wear from the stress. They heat up significantly at 100% continuous load, and eventually start arcing and fail. You DO NOT want a bad breaker, and that's why I advise following the 80% rule in general. |

If you can run 240v, do it. Any serious miner will run his hardware on 240v, nothing but advantages.

Please NO OVER-CLOCKING S4, PSU is not made for that. It is a 1400W PSU inside. @ 2TH with 0.69W for continuos draw
Reading this makes me believe bitmain intentionally killed voltage control in the latest firmware because of PSU RMAs. If that's the case, well, that sucks. At the very least, lowering the voltage needs to be allowed, and ideally increasing it also with a nice big warning that increasing it while using the stock PSU will cause said PSU to fail. |

Is ckpool even compatible with LTC?
No. That's what I figured. Hope this pool doesn't come back up as a BTC only pool, I enjoyed pointing my scrypt ASICs here when they weren't rented. |

I just have a quick question , hopefully someone can give me some advice .
I have and Antminer S1 and a gawminer Bitfury , , now here is the catch , my internet has a data cap of 300gb a month , How much of that 300gb would my 2 little miners use ?
I cannot say exact amount. But miners are normally pretty small on data usage. Which miner do you mean with gawminer bitfury? I have the bitfury , its like 1.2-1.4 mgh . And thanks for all the replies on the help . I had forgot I posted this to see if anyone had any ideal on what they would use . Our cap is flying though the roof for some reason and i had to stop my mining for the moment . We cant figure out why or what it is . My son and me didnt thik it would be the miners since I use minerspool , supernova , coinminers and manhattenminer as my pools . i just didnt believe it was using that much to begin with . I'll bet you're leaving your bitcoin wallet open. If so, that's where your bandwidth is going. The wallet can easily take a few GB per day, while mining is measured in KB or MB. Turn your wallet off, and your miners back on. |

@Prelude,
Requests were in to the programmers and engineers. Unfortunately, we wrench monkeys can't write the firmware. Please be patient!
Thank you
Great to hear! All I (and many others I'm sure) wanted was word from Bitmain that they acknowledge the issue and plan on fixing it. Communication is key! Thank you. BitmainWarranty, There is also an issue with p2pool in the latest firmware which didn't exist in the Oct. 16th firmware. Do you know if that's being looked into also? Any ETA on a new firmware version? |

Is there a test port up for LTC?

I guess now is the perfect time to short LTC/BTC and LTC/USD
When looking at the hashing power on the LTC network, that down trend will continue.. it all started after they announced the're stopping development... Where did they announce they had quit on development? I only saw the quote saying that LTC doesn't need more development right now, it needs more acceptance. If that's what you're talking about, that doesn't mean there won't be more development in the future. I saw some posts saying they stop development, maybe it was taken out of context.. I think so, I haven't seen anything stating that they had stopped development. Only that lack of development wasn't LTC's main issue. |

Received my hot air soldering gun So I gave it a try to remove my burned A2 chip. At least I think it is burned and broken I don't know, looks like that might buff right out?  Good luck!! |
