According to hno (engineer from KNC) we should not go above 50A per VRM/die and 200A per board. According to Bitcoinorama (KNC Tech Communications) it is safe to go up to the firmware built-in limits, which are 64A per VRM/die. There is no 209 or 210. Check the topic for available values. |

Hi,
so after the recent difficulty changes, I thought of past times when 3 of my November Jupiters could do easily 1,5 BTC a day, then 1,1 then... right now it's 0.9 BTC for all 3 give or take some pool luck. So I would like to test safe limits - some 10% increase of hashrate would be great.
As far as I understand this thread, it's mainly about October Jupiters. While I could rise frequency, I will have trouble raising voltage, as I do not have the 0.99-tune FW.
While I do have significant Linux experience (and feel on the BBB like home), I'm quite a chicken when it comes to potential toasting of not inexpensive hardware. Is someone here who has tried the OC on a November Jupiter with or without changes to DC/DC voltage?
Or the other way round: How do you adjust voltage on November Jupiters? I have no "Advanced" Tab in my FW.
Rico
I don't think you can overclock November Jupiters. They are already maxed out.
All this seems quite kludgy to me. You are copying a file just to delete all its contents and then paste something from somewhere.
Because I am no Linux guru and do things as I can, helped by Google  |

Yeah that is awesome, it's great to see an entrepreneur who started several years ago getting the return on his investment. He has put in all that time and carried the risk, this is capitalism and a free market at it's best. People can mine wherever they want based off their needs for compensation. Whatever they feel is fair. If you're worried about how much he makes, you're not looking at the big picture. It takes a lot to run a pool, it's a business, it has expenses, taxes, legal retainers, all kinds of things you don't get to see behind the scenes. Plus you need to plan and save for growth, emergencies, contingencies, security. It all adds up, does he make a lot, sure, but I'm sure it's well deserved. At the end of the day I'll bet a good portion is going back into keeping things running. You want him to have a large reserve, it means he can weather the storm.
And his calculation was on one of the luckier days. If he did the same calculation today he'd see I've *lost* money since last night. My calculation is very rough and only based on the total hash rate of the pool, which is again a rough figure. I used a general income calculator, which assumes 100% luck. I guess I am not very far off from the actual income, which in anyone's eyes look amazing, so congrats on that May I ask again about the orphaned blocks. How is BTCGuild defining these in comparison to Bitminter? Do you have 2 categories or just 1? And you pay for all of them? Thank you. |

I applied sed sBD1BC1B </etc/init.d/cgminer.sh >/config/zzz.sh ; /config/zzz.sh restart And bumped up a bit of hashing rate, My Oct Jup never had any die issues and seems to run great.. I see people mention 211 and 231.. is their a single line sed command for these? No. Here is my current zzz.sh file.. http://pastie.org/private/f5ywbvozimw4ritvdamzgI don't see any overclocking values in this file. You seem to have installed Bertmod, which replaces the original cgminer.sh file with a new one, that does not have the 0x86 value needed for overclocking. And then using the sed command you have created a copy of the new cgminer.sh file. |

And in regards to pool income as of today:
90% PPLNS = ~32BTC a day
10% PPS = ~9BTC a day
minus orphaned blocks
= ~40btc a day
And your point is what exactly? To answer opentoe a few posts back, who was interested on how much the pool owner makes. |

6 blocks each hour is for the whole network. For the pool only just calculate 3% out of the total pool speed = 3% * 2700TH/s = 80TH/s So 80TH/s is around 28 btc per day at current difficulty. But because there are people using PPS, it is more than 30btc a day. Now imagine what it was 2 difficulty retargets ago. Probably around 50btc a day Subtract 1% from the 3% fee for orphaned blocks, which are roughly 1 in 100 blocks. And PPS is barely over 10% of the pool now. And don't "imagine what it was 2 difficulty retargets ago", because BTC Guild was not 2700 TH/s 2 retargets ago. Why so many orphaned? I can only compare to Bitminter, but they have only 3 for the past 1600+ blocks. Having an orphaned block is pure luck and not related to hashing speed, right? What was BTCGuild speed 2 retargets ago? BitMinter has had way more than 3 in the last 1600. I'm curious now what they use to differentiate between "stale" and "orphan" considering those mean the same thing when it comes to blocks. They've had 3 stale+orphan in the last 100, 5 in the last 200, 7 in the last 300. Smaller pools will have more orphans than larger ones purely because they're less likely to be able to confirm their own orphaned block than a large pool. It's also very common to see random events (1 in 100) show up in clusters, meaning a small sample size can show a much larger (like the 3/100, 5/200, 7/300), or smaller (0/300) occurrence just due to the distribution of random events. UPDATE: Guild has had 4 orphans in its last 600 blocks, 7 in the last 850. That's not far off from the approximation of 1%, which is what has been estimated by most pools for years. Bitminter differentiates and pays out Orphaned blocks only. They only 3 for the last 1600 blocks. They never pay for Stale blocks. According to http://bitcoin.stackexchange.com/ this is the difference: http://bitcoin.stackexchange.com/questions/5859/what-are-orphaned-and-stale-blocksSo does BTCGuild pay for Stale + Orphaned? And in regards to pool income as of today: 90% PPLNS = ~32BTC a day 10% PPS = ~9BTC a day minus orphaned blocks = ~40btc a day |

Can someone show me the math on how to calculate the fee's I'm paying here? I know it is %3, but I want to know how much I've actually given to The Guild over the amount of time I have been here. Of course it isn't one of our charts.
Total Earnings / 0.97 = Amount you've made before fees. Difference is the fee. I was looking for that difference I guess. When I see 1 bitcoin in my dashboard does that mean you already have .3 of it? Ok, that's easy enough. And the pool operator gets %3 of every block we find which is 25 BTC at the moment. That is approx $18k USD. Operator brings in about $540 for every block and how many blocks does the pool solve in a day? Trust me, not good at math at all, am I correct in trying to figure out how much the pool owner makes? Let's say it takes 10 minutes to solve each block, (usually is 4 minutes) but giving a big buffer here. So 6 blocks solved each hour, 6*24 = 144 blocks solved each day. 144 * $540 = $77k. I must be doing something wrong. Can a math genius help on this? I'm just curious to know how much a pool operator makes if %3 is the cut. I'm only asking here cause I mine on this pool and there is a fee. I probably fumbled the math big time, so I do apologize if it is not correct. I do expect it to be wrong, cause $77k seems way too high. Thank you 6 blocks each hour is for the whole network. For the pool only just calculate 3% out of the total pool speed = 3% * 2700TH/s = 80TH/s So 80TH/s is around 28 btc per day at current difficulty.

I can't imagine what Cyphers house is like right now.
You would probably not believe me, but you would feel cold in the room where the miners are if you wear only a t-shirt. Ambent temp is around 20C, but because the miners are in between 2 open windows on the opposite sides of the block of flats the air draft is quite noticable and it is not even very windy outside. If it is, then it can get really cold  I actually enjoy the miners as they are somewhat quiet, yet they warm the whole flat very nicely - I can open/close those 2 windows and regulate the temperature as I wish. Usually they are barely open during the day and fully open during the night as the miners are in the living room, which is only used during the day. |

The whole talk about 8 Neptunes was just to say that mains power would not limit a house to only 1 Neptune.
This I agree. But 8 is a bit optimistic Most people don't have 200A service and a shed I could probably run 2, but would need a very powerful aircon to cool the air 24/7, which would be impractical as I don't have a spare room for them. I could rent a separate flat just for the miners, but paying rent + electricity would be much more expensive than just hosting them in Sweden/UK. Then again we know nothing about the final design/specs, so I would not jump to any decisions yet. Plenty of time to make adequate arrangements |

24000 Watts during the summer.
I hope you live in the Arctic region or you will have serious cooling problems.
Actually I have a purpose-built "miner shed" with two open ends, with air filters and an array of fans on the intake end. That's where the miners live during the summer months. I don't think you understand the thermal dynamics of a 24Kw heater lol. The fans might melt, or catch fire, depending on what they're made of. Unless you already run similar equipment, in which case ignore my comment lol. Well, the fans are all on the intake end, so they don't handle the hot exhaust air. So far I've only put maybe 5kW in the shed at a time. Which country are you in?
US. Don't know which part of USA you are in, but if you happen to get 25-30C temperatures in the summer I can tell you with 100% certainty that 24kW would not survive in a closed non-air conditioned shed. Well it's not closed. It's built wind-tunnel style with the front and rear walls missing. The front wall is replaced with fans. No I haven't tested 24kW in it, but 5kW seemed OK. 5kW during the winter vs 24kW during the summer? |

There is a limit to the amount of hardware households can sustain. Neptune in theory is currently the ceiling until another full step down in process node to sub 14nm, as it's power consumption may limit one device per household mains.
I don't know what kind of mains your house has, but mine has 240V coming into a 200A panel. If I were to commit only half of my house's electric capacity to miners, and if I assume that a Neptune will consume 3kW, I could still run 8 Neptunes at home. Or are you trying to subtly tell us something we don't know about Neptune's power requirements? 24000 Watts during the summer.

So we small miners might be mining bitcoins looking like toy sales in the small neighborhood candy store while a Toy-R-Us and a Walmart are under construction on the same block.
This is what myself and a handful of others have been saying for quite awhile now. Are you just now seeing the writing on the wall? There is a limit to the amount of hardware households can sustain. Neptune in theory is currently the ceiling until another full step down in process node to sub 14nm, as it's power consumption may limit one device per household mains.

For what its worth: I submitted a feature request to cex.io requesting GHS/IXC feature, just as they did a while back with GHS/NMC.
Thanks for your interest. Even if I do not know about this feature. Does it tell you the global mining on IXC by Cex.io service? Would you mind clarifying what a GHS/IXC feature is? Thanks. Selling cex.io/ghash.io GH/s (hashing speed) for IXC. |

Dude it's New Year's Day. We spoke about this just before Christmas. I'm not in Sweden and I haven't had anymore of a conversation on this subject then when we last spoke. Just making sure my question hasn't fallen on deaf ears We've seen a few ASIC related fires, so don't blame a guy for enforcing safety  Judging by the time they took to agree upon releasing it. I doubt they would have done so unsure as to the consequences of using the 64 A option. I personally know for a fact there is still a margin on top of that figure before it Max's out. It's not a great deal more, but if they were happy with the release and made it an official one, than i'm confident it is fine as it's not redlining at 64.
That sounds awesome, so if you can verify it with the engineers I know a lot of people would be gratuful I have spoken with a few fellow miners on irc about this and their comment was that until an official answer is provided they would go with hno conservative, but safe limits. |

Bitcoinorama, any news in regards to the max safe current for 24/7 use?
I assume the 64A option will be removed if it is deemed dangerous?
