That's the first time I've ever seen heatpipes blow out. I work as a computer tech and see lots of nasty problems, but I've never seen anything like this.
Normal heatpipes can't really expand the way a vapor-chamber can, they usually just crack at either end when pressure gets to high and whatever medium was inside them leaks out. so the medium leaks out on your motherboard, nasty  |

you forgot riser cable , at least 1 powered for 4 cards.
you won't cool 4 cards in a case.

you do not talk about the powersupply in your quote.  IT's important and you need at least a 1000W high quality to be safe. 3 * 250W + 100W + margin |

Some questions: 1. I think I finally understand how these >4 GPU systems work. I didn't know what a riser cable was, but basically it allows you to run a GPU off a x1 port? Correct me if I'm wrong. It needs to be powered though because the x1 port doesnt provide as much power as the x16. I'll also probably end up buying x16 to x16 powered risers. some of the power for the card comes from the pcie slot and 3 is the max the motherboard can give so you need an external source of power ie the molex plug 2. What does it mean when you have a powered riser with Molex? What's Molex? the molex plud is the 4 pins D shaped CD-ROM and PATA harddisk power plug3. Is the 7950 better than the 7970? I've heard here that it is. Not completely sure though, and it doesnt make since due to it being lower in the series. Won't go 7990 because of the price gap. The 7970 does better than the 7950 in hashpower, but can I overclock 5 (or even 6) 7950s to 7970 speed? to mine 7950 is almost as good as 7970 and cheaper4. Does the PCIe 3.0 increase hashpower at all over the PCIe 2.0 slots? no advantage |

you just built 3 machines like that cost effective  |

NO CPU mining is out on BTC and not profitable IMO in LTC. |

Cette carte là est parfaite selon moi, mais on la critique car elle a le voltage locked.
Tu veux rouler avec un boitier ouvert ou avec une carte de pintes de laits ?
Pour 1 ou 2 cartes tu peux vivre avec un boitier ouvert mais pour plus il te faut des risers (câbles qui permet de mettre ta carte graphique sépatré de ta carte maîtresse pour une meilleur ventilation.
une carte maitresse AMD avec un petit CPU AMD, plus de prises PCIe possible
RAM 2 GIG ou 4 GIG pour LTC
très bon powersupply, calcul 250W par carte 7950 + 100W pour le reste de la machine + 15% de réserve
lit le thread sur le case crate à 10 $

run open case, no side on it, and yes undervolt if unlocked
|
|
|

il y a un thread pour modifier toi même un RISER 1*16 en ajoutant un molex, masi je n'ai pas le lien |

quelle zone rouge et quelle lupiote une image du client aiderait tu pourrais monitorer la température et le voltage avec afterburner de MSI, si tout est ok alors pas de problème tant que tu soumets des "proof of work" et non pas des erreurs. |

one miner is GPU and the other CPU that's why , but cpu mining is not cost effective if you pay for electricity

1 BTC a day ? a few ASICS |

I don't know where you live but those prices are expensive for old technologies, look for a 7790 if you want inexpensive cards. |
|
|
|
yes less, since your graphic card can only do so much work, it will split the work between your 2 coins. It's not like nmc that are free from your pool. |
|
|
|
|
On the pcie slots side YES, on the chance of making 7 cards work it's something else.
What I read is that 3 or 4 cards is easy more is difficult

of course you realise that the number of BTC TODAY has nothing to do with how much you will receive when you do get the BFL If you order now then in september when you receive your machine you will produce much less BTC  |

I have an 6970 HIS stock cooler on it and it's warmer and louder then my 2 Gigabyte 3 fans 6970 even if the HIS is unlocked and undervolted.  go with the 3 fans Gigabyte and open case or lots of fans over a stock cooler even if undervoled. but that's not with 7950 |

get an other riser, powered if possible and an other small power supply and look how to join it to your existing 24 powerplug so that it will turn on and off like your regular powersuppply
