Build two DIY1 boards in a cool Bitfury S-HASH case. Used a Sunon Fan for some cooling, this fan is rather noisy but don't have another one that fits right now. The boards a getting a bit hotter than outside a case. With 13.1V they went over 48 degrees Celcius, tuned back the Voltage to 12.5V, temp is stable at 46 degrees C and the hash at 32 to 35 GH/s, I think this is a nice temp-performance-ratio.   |

Nice! What supply voltage? 4 x DIY2 on a stock PSU 12 to 12.05 V 4 x DIY1 on a dealextreme 120W psu 13.1 V |

Unfortunately my old psu is off. It has problem and i though i can make it work but i cant. For that i must buy a new one. I see that each board needs 25w to work. What is your opinion to choose a cheap 550-600w psu or a good 400-500w. I think in the next months to buy more boards. Thank you for any advice
Don't buy a BeQuiet Pure Power L8 600W. It only supplies 11.5V on the PCI-E connectors. It's realy weird but I measured it with a Fluke Voltmeter 11.5V is the max. Then I took a SeaSonice S12G and this PSU works just fine at 12 V. I think you should best use am adjustable PSU. For example one like Intron suggested: http://www.ebay.com/itm/30-Amp-12-Volt-DC-13-8V-Regulated-Power-Supply-for-Ham-Radio-CB-US-SELLER-/360874766820On these type of PSU you canadjsut the output voltage, sometimes even up to 13.5V or higher. I use this one http://dx.com/p/12v-10a-iron-case-power-supply-silver-ac-110-220v-124302 on 4 boards @ 13.1V and it works just fine. They hash at 33 to 35GHs with thermalpasta+heatsink+fan(s). Take notice that if you overclock/volt them warranty voids. |

marto74 from technobit ask 185€ for 60Ghash Rev.2 bitfury with the chips board, you don't need buy chips
That's what I was afraid of... price for production SHASH is relatively high..  |

Offerte van leverancier/assembleur is binnen, check het (internationaal) topic.
Kort voorbeeld, als we 50 boards maken zijn kosten per board ± 183 euro (excl BTW)

Did we talk about Rev2 chips ? why not 32 chip board it will save the components and make more affordable + push 120Ghas per board make more interest in project
I only have the design and (Gerber/BOM/etc)files for the S-HASH. Don't know if other designs are available for free/opensource? That's why I choose for the S-HASH. |

any update?
Today (or tomorrow at the latest) I will get a quote for 25 - 50 pieces |

I will test this with 1 board is 13,1V the max for the boards/chips? I use thermal paste and fan for cooling. What is the max temp? around 60 degrees Celcius? |

that's why these boards "only" hash at 26 to 29 GH/s. I will try another PSU tomorrow.
