What is being auctioned? Why?Its recently been brought to my attention that the 'pool information' section within my setup guides may have been unfair as only a small number of pools were arbitrarily chosen and displayed. In order to fix this, I will be holding monthly public auction between the major pools in order to decide which pools are displayed and in what order.
Ad Format- There are 3 pool slots for sale.
- Final bidding order matters - the top bid will receive the first slot, the middle bid the second slot and the lowest bid the third slot.
- The ads are to last from the 1st January to the 31st January, during which impressions are projected to be 500,000 per slot.
- This traffic is as targeted as can be - to those who have just bought miners and are looking to set them up and direct them towards a pool.
- Pool slots feature a direct registration link and quick startup information.
Auction Format- Auction will run for approximately 15 days, to end at midnight London time / 3PM PDT / 6PM EDT on Wednesday 31st December.
- Post your bid in this thread stated in BTC. If two people bid at the same price, the person who bid first will have his slot filled first.
- Bidding starts at BTC 1.0. All bids must be evenly divisible by BTC 0.2.
- Only pre-approved pools on the below list are accepted, if your pool is not on the list please contact me.
- You must pay for your slots within 48 hours of receiving the payment address. Otherwise your slots may be sold to someone else. I will send you the payment information via forum PM from this account ("dogie", user ID 87869). You might receive false payment information from scammers pretending to be me. They might even have somewhat similar usernames. Be careful.
I reserve the right to reject bids, even days after the bid is made. You must pay for your slots within 24 hours of receiving the payment address otherwise your slots may be sold to someone else. I will send you the payment information via forum PM from this account ("dogie", user ID 87869). You might receive false payment information from scammers pretending to be me. They might even have somewhat similar usernames. Be careful.
TaxesThere is only tax due to UK bidders, and there is no additional cost to anyone (apart from me). Just clarifying to making sure its a level playing field and collecting any legally required taxes. US and rest of world - bid as normal, no VAT.VAT registered UK businesses - will be invoiced an additional 20% VAT on bid prices [which they can later reclaim at no cost] VAT registered EU businesses - bid as normal, please let me know your VAT registration number. Non VAT registered UK - bid as normal, I will pay 20% tax and take the hit. Non VAT registered EU - bid as normal

I can definitely understand the points both you and kano made and agree with you that the addition of empty blocks to the chain is a necessary evil in the current state of things.
The issue wasn't whether it's okay to generate empty blocks or not. The issue is a pool creating empty blocks when there are transactions pending due to a pool's poor optimisation choices. P2pool by itself does not do anything to limit transactions as an optimisation, it just uses whatever it is given by the bitcoin daemon. That points the finger at the custom antpool implementation as being responsible. Again, please remember there are two sides to the pool - a typical non p2pool pool and a p2pool pool. The activity your discussing is done on the non p2pool pool, so there is no 'custom implementation' of p2pool going on there because its not p2pool. Engineers have been notified to look at it. |

What is being auctioned? Why?Non intrusive ad space in my setup guides is being publicly auctioned. I work for the community full time and am not funded by the community. Donations have not exceeded $100 in total this year and so I have to find a way to keep the guides sustainable and FREE for the average consumer. Selling ad space is one such trial.
Ad Format- Leaderboard style (728x90px), static images (jpg, gif, png), non annoying colors.
- Ads may not misrepresent, lie, be inappropriate, be (or link to) NSFW content. I reserve the right to reject ads for other reasons or remove ads even after they have been accepted.
- There are 5 ad slots for sale. One slot will be placed after sections 2, 4 and 6 in all the guides listed at the bottom of the post.
- I will randomise which ad is placed in which slot on each guide so each slot receives the same impressions.
- The ads last at least 10 days starting from when they are put up. Traffic is expected to be 15,000 impressions per slot over the period.
- This traffic is exceptionally targeted to the hardware subforum, and more specifically to those who have either bought or are looking to buy miners.
Auction Format- Auction will run for approximately 8 days, to end at midnight London time / 3PM PDT / 6PM EDT on Wednesday 24th December.
- Post your bids in this thread. Prices must be stated in BTC per slot. You must state the max number of slots you want.
- The notation "2 @ 0.30" means 2 slots for BTC 0.30 each. Not 2 slots for 0.30 BTC total.
- If two people bid at the same price, the person who bid first will have his slots filled first.
- Bidding starts at BTC 0.30. All bid prices must be evenly divisible by BTC 0.05.
I reserve the right to reject bids, even days after the bid is made. In particular, bids from people with less than 15 activity points are likely to be rejected. I recommend not getting into a bidding war with someone who has less than 15 activity points, as their bids might not be accepted, but your latest bids will still stand. If you need to know right away whether someone's bids will be accepted, PM me. You must pay for your slots within 24 hours of receiving the payment address otherwise your slots may be sold to someone else. I will send you the payment information via forum PM from this account ("dogie", user ID 87869). You might receive false payment information from scammers pretending to be me. They might even have somewhat similar usernames. Be careful.

Dogie's Miner Setup Guides:.Dogie's USB Setup Guides:.Dogie's General Guides:
tldr for getting started:- Starting bid is BTC 0.30 per slot, bid increment is BTC 0.05.
- 5 slots being sold
- Bid using "slots @ price each" notation (3 @ 0.30 means 3 slots @ BTC 0.30 each)

We did business back in March so not worried about anything other then shipping. I have a deal with Fedex. Are you willing to work with me on sending you shipping labels for pick up I would like to buy up a few units. Can you let me know the dimensions for shipping I can get a quote.

My Sp 20 is disconnecting/ stopping mining for no reason. I have 1300PSU platinum going and it keeps knocking itself offline. The fan is still running so the only way I can tell is when I log into it, which I can't do at that point. I log into my stats page on eligius and I can see I am zero hashing. If I reboot PSU then it comes back on. Seems to be happening between every 4 and 24 hours. Is anyone else having this issue?
I have reset to factory and now trying to run. we will see how this goes.
Exactly what I was having for a few times today. Is it running hot? I moved it to somewhere cold, and it hasn't crashed yet. *touches wood* In garage. 30 degrees in there. Its not hot to the touch at all. psu wires not hot. I just reset to factory. maybe this will do it. time will tell. What is the temperature shown in the Asic stat page? i had it in somewhere around 27*C, and it crashed afterwards. It's at somewhere 5*C now, still going with the stats in my last post above. here's what I have. Why are some in yellow? The max temps are 125*C for each of them. Once it hits 120*C I think they start to throttle themselves. According to what I've read, try keeping them at < 115*C for them to run more stably. I'm suspecting that the high temps in there might've caused the controller board to freeze somehow. Max spec temps are 125C, max 'mining' temps are 120C, anything below that it considers there's more headroom and will try to push up clocks + voltages within the voltage and power ranges set. Temperatures in ST gear look hotter than the competition due to the location of the temp sensor, but max temps are all in the same ballpark (100-130C). |

Hi, Please advice if this is alright in terms of temperature? I don't want to stress my C1 http://puu.sh/dwCPP/5fced7a60b.png (the one on the left, the AC is pointing at it while the second one is about a meter away from the AC) my 2x C1 miners are hashing 800GH/s consistently........... Thanks!  .... You do have watercooling on right? Those temperatures are not right, stop mining. |

New version of cgminer I just posted, version 4.9.0, has full avalon4 support. These are nice quiet devices and the power claims are consistent with my testing. I run them a little undervolted and am getting ~950GH with 2 modules: 0: AV4 20141122: 200Mhz 43C 35% 0.637V | 984.8G / 943.0Gh/s WU:110.0/m
43C @ 35% fan, would probably be silent within my farm  |

just a thought, an update to RockMiner? dropping the communication score? rockxie seems to have gone AWOL
Everything is being considered in the next round |

Hmmm...I've had this C1 running for a few weeks now and had no problems until last night. When I look at the status page I get this...
I've emailed support but thought I would post here as well. Any help would be greatly appreciated. Thanks.
Hello: You can configure user and selecting freqency throught web. What he means to say is try changing the frequency, doing a power cycle and see what that does. Yep done that...and everything else that anyone has already suggested...including the guys at bitmain. They've been responding to my emails on a daily basis as they give me new things to try, so I will say that they are certainly trying to help me. In the end they gave me an address in the US (I'm in the UK) to send the control board to. Which means I'm already down a week and it looks like this miner will be down for at least another, although it's more likely to be several, weeks. As you might have guessed, I'm not a happy bunny. However, I'm not going to flame Bitmain or be an ass. This is the second issue I've had with Bitmain in the last month, after almost a year of buying equipment, using hashnest and mining on antpool with nary a problem. So the end result is that my other C1's are being sold off and I'm going to let my wallet do the talking with future purchases. Thanks for all the advice... They have a UK address you can use which will lower the cost drastically. |

I know.
These are the most recent figures I can find for London (base tariff)
British Gas: 15.1 pence per kWh
EDF Energy: 16.0 pence per kWh
nPower: 16.2 pence per kWh
E.ON Energy: 14.8 pence per kWh (2012 increase not included)
ScottishPower: 16.8 pence per kWh
SSE: 15.5 pence per kWh
That's because those are base tariffs - they're designed to be expensive so they make money off you if you don't switch. |

Mining isn't my thing but judging by the stack of S3+ and S4 units that a friend has asked me to sell for him I assumed that the S5 was not too far off...
Most likely your mate wants to sell because profit is not worth the noises after cost of electricity at current BTC price. I'm using my S1s, S3s and S4 as space heaters and make little profit. My flat is so hot that I have to keep my windows open. Either your electric cost per kwh is high or your pool is not paying enough because I am making profit using S3's and S4's. $.12 a kwh electric and Slush pool. Winning combination. Power prices are about $0.24 KWh in London for a standard domestic electricity tariff but my friend uses a power broker to negotiate much lower rates than that because his farm is in his industrial printing plant and his farm uses a small percentage of his overall consumption. As to why he is backing out of mining I'm not sure but I suspect he doesn't have the time to dedicate to mining to justify the slimmer profit margins. I'll try to have a proper discussion with him about it before he pulls the plug . He's a canny businessman so I'm sure his reasons are sound and personal to his own circumstances. I'm not sure on numbers but I think he has a lot of hardware. I remember him saying something about 30 S4s at some point. When he finds out how much I'll charge him in commission to sell them maybe he'll change his mind  Thats rubbish pricing, I have $0.13 in standard residential in the UK. |

I don't know about a sea of tiny chips, but I'd much rather see a multi-chip high-hashrate design than a single- or few-chip high-hashrate design. Increased surface area decreases cooling requirements, distributed power decreases PCB requirements, and increased modularity increases reliability and repairability. From an owner/hardware-maintainer standpoint, the most problematic machines I've run were the ones with hot single-die setups.
i had always thought it the other way around.. the larger the surface area, the more cooling required... you are not spreading that heat from the centre to the edges of a large chip, you are seeing equal heat across the chip - so a bigger chip = increased cooling requirements. You're both saying the same thing, distributing hashing power over multiple smaller chips increases the surface area / GH = 'easier' to cool. That being said, its not difficult to cool large chips at all, it just means more cost and weight. [First step up is copper base, then copper heatpipes]. |

Second, you devalued your own name when you went from being a seemingly legit manufacturer of hardware based on other people's boards, to just making up impossible specs and faking "proof" of them.
Third, I did get an official response from your company before I posted negative feedback. That official response was handwaving about a magic board and a faked cgminer screenshot.
Allegedly falsified. What would you do to make it right if its not faked? There's two things there. Not only do the WU values not match the hash rate, but the reported hash rate is literally a physical impossibility at the reported frequency. And yes, I am using literally correctly. Honestly I tried to give them every chance to say that they just made a mistake, but they're just sticking with it. 860GH/s is a physical impossibility at 950MHz. Even outside of the extremely dubious claims on the power efficiency, there are several things wrong with what was posted. Is it possible that they ran that on an original pentium and the fdiv bug made the frequency and has hate much higher than they should be? Well, no. But even if it were, you rerun the tests and update with the real values. Not that it matters, but if hit 900GH/s and 0.65J/GH at the wall, I would remove the negative trust, add positive, buy a Zeus, and hire them any time I need a board design done on top of a big public apology. Sounds good, lets see how it goes. |

I have 2 U3's it running on my PC, getting 60+ with a PC PSU, want to move it to a Pi so I can run it 24/7.
Occasional zombie's, but it seems to happen on my slow ION system, but not on my i7 system, probably some USB timing problem.
What RaspberryPi OS-all-in-one-miner-monitor would you recommend for the U3?
Any of them, MinePeon, Minera etc. |
