Pool shows 4.6ph/sec rollin, but none of my miners can connect, they all rolled over to their backups.

Thanks. Did it help? I am not sure what % of the sound (72db at fan 20 for the stock fan) is caused by the fan itself and how much is caused by moving the air through the metallic grille/sieve. The stock fan is supposed to be just 61dB, but SP20 produces way more than that (up to 72dB close by).
I'm seriously considering dremeling that out and taking a new measurement. |

Kano what is going on with the pool, my miners are running hot, they block, hash rate not showing correctly on you web page, i restart them all the time.
Not having anything like you're talking about here personally. Miners run hot, that's what they do, do you think kano's pool is somehow making your miners run hotter? |

Just switched to Armory after hearing some good things about it, but after a week of use, I seem to have two issues;
1) All of my incoming transactions are still at 0 confirms, even two transfers from cex and coinbase. According to the transactions from coinbase and cex, they're complete and confirmed
2) I've restarted Armory once after a reboot and it went through a 6 hour process of building the databases again, is this something it does every time?
Ultimately I'd like to know how to fix these issues so I can see if I want to use Armory or just get my coins out :p
TIA

My SP30's hosted at SPTech is reported by slush to have a 24-hr hashrate of 3.007 Th/s.
This seems totally wrong seems the advertised speed is at 4.5 Th/s for SP30's.
I have SP31's running somewhere else but that's being reported at 4.7 Th/s (advertized speed 4.8 Th/s)
Is anyone else's SP30's running a 24-hr hashrate of 3.0 Th/s?
It's been a long time since I've heard anyone say anything good about slush's pool. Everything I heard recently is you want to avoid it, because it has a flawed payout mechanism. Maybe try Kano's ckpool? https://bitcointalk.org/index.php?topic=789369.0;topicseenM I switched from slush to kano myself |

And another!  Turning into a good day. This was nice to wake up to ... looks like you put a lot of work in Kano, hope you were able to take a break And another one this morning too |

As I'm relatively new to mining, sorry if this is a silly question that just everyone knows.
Looking at the worker page on kano.is it says my total is 7th/sec, but looking at each miner individually they show a total of 11.4th/sec, where does that discrepancy come from?

Pool seems to have lost almost 2 Petahash/sec.
|
|
|

... and in case anyone didn't notice We just found another one at 58.37% of expected (network diff)  Yay, I felt a little silly joining right as the pool hit a +210% block, I felt like a bad luck charm. |

That's kind of interesting. |

Pool went down unexpectedly for 95s so most people will have failed over.
It's back up of course.
I'll be working on moving the shift changes live later today which may help with the cause of the above short outage.
I'll post here when those changes are happening.
Is that why 7 of my 8 workers show inactive? Must have failed over to my backups. |

What are your settings?
start volts: 1: .62 2: .62 3: .62 4: .62 Max Volts .661 max power: 1: 150 2: 175 3: 150 4: 175 Mining rates: 1229.41GH/s and 1237.13GH/s fans are both set at 20%, I had them a bit lower but temps got a little higher in my mining area recently. I've seen a few people utilizing different voltages now... I'll have to give it a try. Thanks! Temps okay at fan speed 20? No problems, but with all these boards and asics, YMMV so test it for yourself |

After a week of mining with ghash.io and seeing an awful return on my 12TH/sec, I'm moving over to kano.is for the next month or so to see how the pool fares.

It depends on a lot of things.
If you're looking to mine bitcoin, your electrical costs and if you have space to deal with mining is important. Right now with the low bitcoin value its very hard to turn enough profit to see ROI on your miners if you bought them today. Lets do a little math to show you what I mean.
Lets say you have normal kw/h energy costs of $.10
Lets say you buy two Spondoolies SP20 boxes for $500/ea
Then you need a PSU for them, $180
So you're $1180 out of pocket, you get your 2 miners running and you start making bitcoins. From those miners, you'll generate around .8 BTC a month or roughly $160.00 in BTC. Those miners will cost you around 1.1kw/h to run, or $.11 per hour or around $80/month. At this point you're making $80.00 a month, it'd take more than a year to just recover the cost of your miners. A lot of this is variable month to month depending on bitcoin costs and the difficulty in generating bitcoin, as the global mining pool gets bigger, it gets harder to mine btc.
If you have really cheap electricity and/or you're interested in being a part of the technology for the long haul, then go for it, just don't expect to make a bunch of money on this. You have a better shot at making money of waiting for bitcoin to bottom in the low $100s like a lot of people think it will and then hold it for a couple of years looking for it to go back up.

some SP20 pr0n for you: >snip image< got an EVGA 1600w PSU sitting at home waiting to plug in - I think I'll need another PSU of not massive wattage to get all 4 going It has 14 PCIe plugs, right? So, you need just another PSU with at least two plugs, but i would just get EVGA 1300; this way you can downclock to ~700W/1250-1270Gh. However, if you want to downclock, the trick would be how to downclock them with just one or two PSU. You would have to do it one by one, bring to stable hash, then switch off and do another. what is to the left of them-it looks interesting. I have an EVGA 1300w plugged into 1 and a half SP20s. that pulls about 1100w. The 1600w is plugged into the 2 remaining PCI-E sockets on the 2nd one, the 4 on the 3rd and again 2 on the 4th. That pulls about 1400w from the wall. There are only 9 PCI-E sockets on the 1600w PSU I think I'll swap out the 1300w and get another 1600w, then I can power all 4 across 2 PSUs leaving about 2-300w spare The unit on the left is a tumble dryer !! What speeds are you seeing? I'm running two SP20s off of a single EVGA 1300G2 and getting 2.4TH/s between them without issue |

....
And 2 sp20 cost 3.7 btc
No. 3 SP20 cost 5.55 BTC 2xSP20 cost still $595.00+$595.00+shipping = Ugh, I do not want to know this number I got in on the GB for those, so $1000 with no shipping charges, fortunately I already had an evga 1300 G2 from a computer build, so that's a cost I didn't have to eat. Like I said, I'm not going to get rich doing this, I'll generate some BTC to hold and I like being a part of it. |

Man, I love these things.
Running 2 SP20s off of a single EVGA 1300G2, fans at 10%, getting 1.18TH/sec from each for 1100 watts at the wall.
That's about $120, give or take %20 for electricity for each one. Are you paying for that or stealing it from your neighbor? Anyone buying miners now, how are you going to break even? Please tell me the secret!!!!!? Based all on risk and "hoping" what will happen? I don't think you read that correctly. I'm getting 2.4TH/s combined by running them off of a single PSU, electricity costs where I am are about $72/month for that draw. I'll generate about .9BTC at current difficulty this month, as difficulty changes I'll get a bit less but unless BTC crashes badly or the difficulty gets much worse these boxes should ROI this year. Personally I'm pretty bullish on the entire bitcoin infrastructure long term. I probably could have done 'better' by just buying BTC and holding them, but this is more enjoyable for me. I'm not in this to get rich, if the boxes are still producing at a profitable margin a year from now, or even break even I'll be pretty happy. |

Kano, I'm unable to register for some reason
edit: nevermind, my username must have been too long, picked a different one.
