Hello, I am considering a setup for a 3x Radeon R9 280x rig, could You suggest me which other parts I should use? To minimize the cost, and be optimal aswell (so the GPU is the bottleneck)? Assistance from anyone who has similar setup would be even more helpfull  Afaik scrypt mining doesn't require much cpu or ram power so I would just go to newegg and find the cheapest motherboard with 3 pci-e slots (probably 1 pci-e x16 and 2 pci-e x1 would be cheapest). PSU would probably need to be 1000W to be safe. I thought I do need 3x x16 PCI slots, since this card has PCI x16? Has to be pci-express not pci. Can be x1 with powered risers or x16 with risers. |

Did I miss something? 1. Dividends are going lower because of Difficulty increase (-> Cointerra launch soon etc.) 2. No new statement from Friedcat 3. BTC price goes up 4. AM Share price goes up too ? (0.28 to 0.38@ Havelock] wtf?  Gen3 tapeout in ~17 days |

Has this hit a tipping point yet? For the average person is it just cheaper to invest than to mine? If not, how much BTC can you mine per day on let's say a 5000-10000 dollar "rig".
Best bet would be to go with knc or whatever asicminer offers next. |

Right now as the asic arms race is in full swing we are seeing exponential growth from 20%-40% per difficulty change. My question is will the difficulty rise eventually slow down? To the point of linear growth?
My prediction is that once we see fully optimized 20/28nm asics we will stop seeing such dramatic increases in difficulty because there will not be much room for improvement.
Also eventually electricity efficiency will become a limiting factor and only the most efficient mining operations would be able to continuously add hashing power.

Seems like a lot of people are assuming that the Gen 3 will be a success.
It is still too early to make such a call considering that the Gen 2 had to be cancelled due to the under performing chip design.
Even if the Gen 3 chip does perform, there are still 3-4 months before they are implemented in functional miners, and that is a very long time in the Bitcoin world.
Could be 2 months till a working product after tape-out. Also I thought gen2 was skipped because gen3 looked so much more promising. Knc is probably the biggest competitor and they will probably ship at the end of q2. Gen 2 was skipped/cancelled due to the poor performance. Have a look back at friedcat's posts. Source? I found this: so Gen2 is skipped?
I'd also be very interested to hear the answer to this. It's frustrating seeing responses which indicate that all the questions in this thread are being read, yet ignored. Yes, it was skipped. FC mentioned this in the past. Apparently the performance wasn't as good as they hoped and they just decided to move on... probably a good move. According to friedcat Gen2 is not worthwhile for 2 reasons: 1) Gen2 would come out relatively late due to some factors outside of AM's control 2) Gen3 shows promising results and the roll-out seems to be better/more reliably organized Thus funds are better to be spent on Gen3 hardware. The production schedule will depend on a risk/reward ratio determined by friedcat. Deviations from the schedule need to be anticipated when rolling out a new product technology, so hedge accordingly when speculating on AM. I'm surprised you are asking as not too long ago you said this: The reason we are seeing such a price dip is because gen2 chips from AM were skipped which lead to a long gap between new hardware. The reason it was skipped was due to unsatisfactory performance and FC believes gen3 is more promising. Also by skipping gen2, gen3 will arrive sooner.
Exactly. Gen2 was skipped because gen3 looked more promising. The only reason it was deemed unsatisfactory performance was because it was compared to gen3. It is not like somewhere along the design process gen2 completely failed. I believe delays are what made gen2 impractical and it is much more likely that delays happen with gen3 than design failure. |

does anyone have a solution?
Have you tried using amd overdrive? Comes installed with any ati card with catalyst. |

Years? If AM pulls through with <0.2W per G and <0.2$ per G on wafer cost in the next few months (and if that is competitive with other companies, which I think it will be) then share price will be over 0.5 BTC in months, not years.
What maths lead you to believe that? You seem to be viewing AM as a pure mining dividend play, which it isn't. AM != cex.io.
No, I just understand that AM cannot compete against everyone else combined. The overall result of that is a declining network share, regardless of the fact that the hash rate might actually be increasing. Why do you come to this thread so often with bullshit math and false assumptions attempting to create fud? I can understand now why you have a yellow ignore button. For anyone who is interested in a serious evaluation ignore mabsark and do your own calculations. Mine led me to believe that if AM can achieve 10%, as was the previous goal, each share would be worth at least 1btc a piece at 30% apr. I've shown my maths, why won't you show yours? If you think my maths is bullshit and my assumptions are false, then show them to be so. Anyone can claim any old rubbish. Because every time your bullshit math has been disproven you create more bullshit calculations next week. A week ago you were telling us that am would have 100th/s by april so we should all base our evaluations off that.. I was assuming the current hash rate to be 100 Th/s and that new chips would arrive in April in order to show what mining income will drop to before the new chips come online. As others have said 5% = 0.5/share
AM has the ability to maintain the hashrate because its chips (according to software estimations) will compete with everything else being sold in 2014. No amount of calculations will "prove" AM's ability to maintain the network either way. Nobody knows the future difficulty/hardware sales/competition but out of all the competition AM and KNC are looking like the most probable asic arms race winners.
If AM have 20 Ph/s, they do not have the ability to maintain a 5% network share if the network hash rate is 250 Ph/s. That is easy to prove mathematically and I have done so. Perhaps you should pay more attention to the words you are actually reading. 20ph of a 250ph network is more than 5%. Increasing hashrate to match difficulty change means AM can maintain more than 5%. I now know that you aren't interested in having a discussion and instead just bashing AM so ill do what apparently a large portion of other users have done which is click the yellow ignore button next to your name. |

Do I agree that AM can maintain 5% for several months? As I've said several times now, I do NOT care about AM hash share. I care about how much of the BTC mining profit share AM has. Do I think they will have 5% of that? No, based on the specs of their gen3 and past track record of actually getting hardware to market, I think they will have more than 5%. I've no idea what you tried to say with those first 2 sentences. I've shown you mathematical proof that if the network hashrate was 250 Ph/s and AM had 5% of it, then they could not possibly maintain that 5% network share for several months if they only had 20 Ph/s (batch 1 is supposed to be between 2 Ph/s and 20 Ph/s. You are saying that as difficulty increases and hashrate stays constant that dividends from mining will decrease. We all know this. The part that is debatable is how AM will expand. Maybe AM will increase solomining hashrate every week to match difficulty increases. Or maybe AM decides to just sell a shitload of hardware. If AM sells 20ph and decides to do literally nothing after that then you are right and AM is not worth more than 0.5btc/share |

Do I agree that AM can maintain 5% for several months? Based on the available information and the maths it produces nonsense I just made up, no I don't. Do you?
FTFY And yes we do believe AM can maintain 5+% global hashrate or we wouldn't be investing. Seriously your calculations are garbage and unrealistic. |

I am also interested in this question. Not sure the best mobo/cpu/psu but for 1000kh/s I would go wi5h 2 x 7950s

Should be ok now.
Can confirm its fixed on android browser now. |

Untrusted security certificate. Might want to get that fixed or removed. |

0.00081605 BTC per share for today
Happy New Year
May I ask how you can check if divs have been paid? Does asicminer always transfer from the same bitcoin address? I'm asking because I'd like to check if my newly (first) bought shares are now coming from AM or still from the seller passing through divs |

Hey Everyone,
HAPPY NEW YEAR!!
So i bought three used Gigabyte 7970's... for cheap! So far, one of the three actually posts and is able to get into windows. The previous owner swears they ran months ago... but they were water cooled. He since put the stock coolers back on.... using thermal compound on the VRM's instead of thermal pads. I've taken the one operating card, cleaned it up... put some proper thermal compound on the GPU and Pads on the VRMS.
The card posts and gets into windows. I load MSI Afterburner and GuiMiner. As soon as i start to mine... the card INSTANTLY goes to 98+^C and core clock Rapidily fluctuates between 501 & 1050. The card does hash, but it's low. After about a minute... It doesnt feel like the card is putting out 98+^C.... so something isn't right! I've installed fresh drivers, i've tried both BIOS switch positions on the card and i'm thinking about reflashing. Any suggestions?
Thanks
Definitely sounds like a heating issue. The card is probably underclocking automatically to avoid overheating. Have you checked to make sure the fans are fully working and you have a solid connection between the heatsink and gpu? |
