27A at 5V? Good luck finding a PSU to run that...  |

too large a fuse and there is no sense in having a fuse. Fuses are protection against bad things happening. Being conservative 49 BE's will pull around 27 Amps so I doubt a 10 Amp auto fuse will hold. Plus modern P/S's have over current protection as well. I guess I'll wait for Eleuthria to chime in before loading the thing full. 27A at 5V. 10A fuse at 12V power supply might just about run it OK, assuming near 100% power conversion efficiency. 15A on the 12V would certainly work. But the 49 Port USB Hub's pull from the 5 Volt line not the 12. Still think the 10-15 Amp is the correct way to go? Thanks, Sam Guys this is a safety thing be careful. You don't choose a fuse based on consumption, you choose it based on how much current the wire can carry. Can someone post a photo of this hub? I gotta see 49 ports to believe it. I guess it has an ATX power connector on the side, I can't see how else you'd get this kind of current into it. A single conductor would need to be about 10 gauge to carry 27A. |

27A at 5V? Good luck finding a PSU to run that... My 350 W Power Supplies are rated for 30 Amps on the 5 Volts Red. Strangely my 600 W Power Supplies only supply 25 Amps on the 5 Volts Red. |

A previous post have you figured out a price for just the hub? Will be listing them tomorrow. I'm waiting on one response from friedcat RE: which rail this pulls off of the PSU from. If it's pulling off 5v, I'm a bit concerned about how few PSUs can actually power all 49 ports at once since very few ATX PSUs will give more than 15 or 20A to the 5v rail. Come to think about it. I am sure that the creation of it that was already in the thought process. So I am sure that all is good. Well after browsing around it is using the 24 pin from a power supply so i think it should be fine. Although will need to know how big of a power supply is needed.   |

You sure about that? The wires on Power Supplies are no where near that size? Doesn't house wiring use 12 Gauge? Edit: OK 5 Volt Red is on 4 Wires on the ATX Plug. So I guess that's how they use smaller wire. |

eleuthria,
I'm happily mining away on BTCguild, but I'm not generating any NMC's, just BTC. I'm connected to stratum.btcguild.com:3333 and based in the US. I want to mine both at the same time. I assigned my NMC address in the settings area, but that didn't help. What am I doing wrong?
Thanks in advance!

NMC's payout on PPLNS only. Turn on "Show" for NMC's in your settings page to see the stat's. |

I really hate this part of it, because I have little/no knowledge of electrical stuff, only the basics (Amps * Volts = Watts, and the permutations of that). Does Friedcat have a thread for these hubs/BE's? |

Thats because most modern motherboards don't use 5v. They use the 12v and drop it to 1.8v or whatever the cpu/ram etc needs. |

I started mining just a few weeks ago with my new KNC Saturn. It hashes steady around 275-285Gh/s. I've noticed my 24 hour earnings just dropping like a dead horse. Is this because of the added hardware that is being introduced to the network and the difficulty rising so fast?
Would I benefit from a pool with no fees to get the most out of while I can?

Difficulty did change a few days ago, you will mine 40% less now. Pool choice is your own. If it is not 0% PPS you will have a high variance. BTC Guild being as big as it is smooths out variance a lot in it's PPLNS format, plus you get free namecoins. |

Is there such a thing as 0% PPS? I think the closest you have is eligius's CPPSRB pool. Which of course isn't PPS. A few things to remember about BTC Guild IMHO. BTC Guild shares the transaction fees unlike many other pools. PPLNS only has a 3% fee. You get the NMC with it (1% ish bonus maybe) Pool has been lucky  103% average since difficulty change. That wipes out any fee. Of course, luck is subject to change. https://en.bitcoin.it/wiki/Comparison_of_mining_pools |

But it does pay orphaned blocks, which is something you don't get from most other pools (without paying above their stated fee). And the 103% is not since the difficulty change. For the last 5 weeks roughly, the Pool Luck chart has displayed the average luck since the chart was implemented. So we're ~3% positive for the last 5 weeks. |

PPLNS is *3%*, not 2%. My bad. Typo. But my point being, is it is less than the 5% PPS. Use PPLNS if you are with BTC Guild. |

Is this because of the added hardware that is being introduced to the network and the difficulty rising so fast? In addition to the things noted above, short term luck ( i.e. yesterday) took a dive, too. Even with a pool as large as this one, variance still happens. 103% for the last five weeks is pretty rockin'. |
