All of my official sapphire plugs have all 3 yellow wires there. And of course are dual molex.
Well, thats kind of my point. With dual molex you should be fine, its the single molex to PCIE cable that is a fire hazard. Not sure if there are 3 wire variants for single molex, but since the limitation is the connector rather than the wires (and the pastic connector has brown burn marks), I dont think it would improve much. Not going to touch single molex to PCIe anymore even if there are a dozen wires  . |

Bad ass pool hoppers that have since hopped away again. Still, was nice to break 100 . As for stats, Im quite happy with what we have now (particularly the none popup stats page), and DrHaribo has plenty on his plate, but if he is still taking requests, it would be nice to see a guestimate of pool blocks / day at the current hashrate (or 24h average) and likewise, an estimate for btc/day (or month) for the miners. I know there are a million calculators where I can get that info too, but would be nice to see it based on actual hashrate and without effort . The bitminter client already has that IIRC. |

You can. Check my sig, bitminter is a high performance java webstart based miner. I know DrHaribo is working on making it easier to integrate it on other websites, please contact him

Bitcoin / Mining software (miners) / Re: Can someone help me install cgminer on linuxcoin?

There is no need to run cgminer as sudo. He needs to install those missing libraries. Try this: sudo apt-get install libcurl4-openssl-dev Hope thats the correct one, not on my linux box here. If it cant find it, then type part of it, like libcurl and hit TAB twice for a list of possibile matches. |

Does not make sense, its an isolated case with a bad connector.
I'm using several connectors like this (provided with Sapphire 5850) and all works flawless.
Id have a good look at them, particularly if you are overclocking (I was testing at 900 MHz but only since a few hours and at stock voltage). 5850 cant draw that much power. Your calculation shows more than what it needs. Well, I would have more faith in a brown melting wire than my "calculations" . As it turns out, these cards usually only draw ~25-30W from the motherboard. That leaves ~120W for those 2 connectors at stock speed. Assuming the card pulls from each plug equally, thats the limit of the 4 pin molex spec at stock speed. Edit: i notice something odd with your connector. The 6pin misses the middle 12v wires? Do you have 3 yellow wires on your plug? To be clear, this is a SINGLE molex to PCI-E adapter. Most (all?) new cards come with dual molex to PCI-E. |

Weird. I have no problems running 300 MHz memory with cgminer, with either windows or linux, 2.0.7 or 2.0.8; but I only have 5850s and 5870s. I even think it does it by default.
Can you post your config file and/or startup parameters? (feel free to comment out passwords and stuff)

Small tip if you are new to linux, to get the tarbal, from the command line you can type (or copy paste): wget http://ck.kolivas.org/apps/cgminer/cgminer-2.0.7-x86_64-built.tar.bz2 then follow ckolivas' instructions: tar xf cgminer-2.0.7-x86_64-built.tar.bz2
cd cgminer-2.0.7
./cgminer
Once that works, you will want to do this over SSH, using "screen" so you can log in and out of the session from any pc in the network. |

Mostly agreed with your points. A few thoughts however; why would it be bitcoin that succeeds and not some other crypto currency? Particularly one backed by a large company (think apple, MS, amazon,..) , or god forbid, a government (Greece anyone?  ). Bitcoin could end up being the next netscape/altavista/icq. Another issue that debated to death here, is the volatility. I feel bitcoin is caught in a catch 22; rampant speculation determines its price and that limits its growth. Every sign of bitcoin taking off will cause a new bubble and that bubble and the subsequent crash will make it tough to gain acceptance. As for porn, drugs etc. Yes, its a vouch of confidence and should be a good sign. But it also gives it bad reputation and it might attract regulation. |

@p4man: Looks like your experienced with cgminer. May sound silly but somehow cgminer does not recognize my configuration file. Is there some special trick or am i just dumb ? I created a configuration file via setings, w, with all information in it but i have to type in all information manually if i restart or close the program.  Oh oops, I thought DT asked me for my config file. Anyway, I noticed if you let cgminer write a config file, it will add zero values for things you didnt configure, notably Vcore. then it will refuse to launch with that config file unless you fill out those number correctly, or remove the lines. but the command to use is ./cgminer -c yourconfigfile |
