Lapped PII 960T + lapped Zalman 12x
Why 100W processor such monstro-cooler? Its unlocked AND overclocked 27%, the TDP will be much higher than 100 watts. |

Started bench testing a Peltier cooler purchased off of Amazon and a temperature controller. Should have went with a PID loop control - maybe will change if I work up to multiple Peltier coolers. Anyway, I did do some testing with one of my OC'd BE's running the same at ~450MH. I can get the temp down to around 15C without any condensation problems. The only problem is that with this temp controller, there is a 1 minute compressor delay built in, so when I hit 15C, it cuts off, waits one minute, and then applies power. When it is off, the temperature is around 30C on the BE right before the Peltier kicks in again. When I upgrade my one BE to over 20Mhz Xtal and bypass the voltage regulator, I am sure I will need all the cooling I can get! Will keep things posted.  Holy crap, that is a lot of solid state relays and other gear just to control one pelitier. There are peltier controllers on eBay for quite cheap ($<20), or you could wire up the internal relay (1 amp max @ mains voltage usually) of any standard model Eurotherm controller to a ATX PSU & peltier. These controllers go cheap on eBay as well (check part / model number against spec sheet to check what installed options you are buying though). |

i think this is ded a bit sad that the community's 10 grand went to nothing.  It died long ago man, you gotta let it go. |

Another classic jusr came up in another thread:

Looks like switches at the bottom... in 2010 there were no stupidly powerful ASIC miners  (they're still working is what suprises me!) Waiiit what is this, water? O.o The source of this image is possibly: http://www.reddit.com/r/techsupportgore/comments/13z049/would_not_want_to_go_to_work_and_find_this/Which is also much larger in size, posted 10 months ago. From the look of the water color it's flood water or sewerage. As long as the PSU in that networking equipment (they look like fiber switches) is sitting above the water level then it will likely keep running. DC electronics at 12v or less will work for longer than you think underwater. Hope they had applicable insurance. |

I have no idea why Imgr keeps flipping my photos.
Have a TAV redhash, and 1 jupiter, plus some singles and USB miners.
Need to get more power run... again.

Thanks for the heads up. I'm not using this miner, but that's not very honest. ("I installed a trojan to extract part of your BTC to support me!") Out of curiosity: what is this miner and why would anyone use it? How does it differ from the -HP series? It was not a 'trojan'. Some of the profits were siphoned off automatically to the creator as it mined. The software was supposedly not meant for public release or use. More or less everyone agrees: You should not use this software. Move along |

My experience with beeeeer is that it mines more or less what I would get on average from solo mining.
If you have lower end machines that probably wont find a block anytime soon I would probably recommend beeeeer, admittedly I haven't tried ypool.
The only problem with beeeeer is I worry about miners disconnecting. I am not sure if this has been fixed in latest versions or not.

Xolominer now supports pool fees option via command line to be as low as 1% (see the OP). If anyone thinks that is too high, well you should probably just go and solo mine with Sunny Kings original client or mikaelh's HP. |

well, if someone has 3million$, he could buy PrimeCoins at stock for half of this money, and start to work at ASIC for other half. If ASIC start the reward will drop to 1-2XPM/block and Prime should appreciation to Bitcoin a lot. The guy earn a lot by mining (90% of blocks) also.
I think it could be a good investment, or it wont?
People have struggled to get GPU mining working, let alone ASIC. Why the hell would anyone sink $3m onto ASIC design - or even $1m - for a coin that has a market capital of less than $2m dollars in total. http://coinmarketcap.com/  |

I'd be more concerned about the potential fire hazard. An old mobo running on a painted box could go anytime.
It's OK, there is nothing else flammable in the vicinity.  |

P.S More powerful processors have much better CPD/power ratios. One 2CPD machine is way better than 2 1CPD ones.
Yes I have a pile of old servers next to me with P4 and core 2 duo equivalent Xeons in them (about 20 CPUs in total) which use about 3 kW in power and they have about as much combined computational power as a i7 4770k... |

I dont think people in this thread are doing this for sick profits. They are doing it to prove it can be done, or for the fun of it, or because they like electronics.
BE cost less than $10 USD now so of course it is more economical to just buy more units than to spend money and time overclocking them (if you really wanted to get a 30% overclock, you could have just paid more and got a blade, which is more economical than an equivalent number of block erupter USBs and more or less 'supports' overclocking with the turn of a screwdriver or two and a few settings changes. (Although, of course, yes, there are better options than blades now, your money could be better spent, etc etc).

$4 (2 blocks) at 0.55 chainsperday (HP11).
2 blocks are worth more than 4$ those past days ! I know, I also don't have a crystal ball to know future market prices. I made my comment 9 days ago. $4 (2 blocks) at 0.55 chainsperday (HP11).
2 blocks are worth more than 4$ those past days ! I am split testing between HP11 and HP10 So far, I seem to be getting better results with HP10 in terms of ChainsPerDay and coins I've mined. However, I've mined 5 blocks in 24 hours... not bad  So in summary: - Poor statistical assessment with very low values of n - Unusually high luck or extremely high performance multi-CPU server is what you are mining on - Confusion about how HP versions work and not really following mikaelh's announcements A+ effort. |

My toshiba tecra with i5 begs to differ, running at 100% for the last 3 months 24/7.
 What did you earn so far? $4 (2 blocks) at 0.55 chainsperday (HP11). |

I fail to see how people make a profit on this coin now, even with carefully managed VPS. I have ceased mining at home on 9 machines now because I can't even reach 1/3rd of break even against electricity (Australia: $0.30/kWh).
Basically the way I now see it is you can only make a profit if:
- You have electricity that is free or almost too cheap to meter
- You are 'stealing' power and/or computer resources from work/college etc
- You have a botnet
