If you are that bothered about cooling, why stack the individual units upon eachother?! Surely the ones sandwiched in the middle retain more heat than if they were standing separate to eachother...  AFAIR Avalon said that they are designed to be stackable upon eachother. Didn't know that, but w.r.t. throwing air con at them, surely it's has a negligible effect to those units sandwiched between?? |
Make my day! Say thanks if you found me helpful  BTC Address ---> 1487ThaKjezGA6SiE8fvGcxbgJJu6XWtZp |

Stacking them like that, you lose the surface of each top/bottom. Just look at the Avalons as if they were individual fins of a single heatsink. You want this fins apart, not touching each other. |

If this is the same idea as spacing on a server rack... wouldn't devices that have front-to-back cooling negatively effect cooling by spacing them apart? EDIT: I assume, in this setup, you would also lose airflow to the top units by adding spacing... I'd leave them stacked. |

The 4 module pictures, it looks as if the modules are in groups of 2 now? Why did they do this? Doesnt this make expand-ability more difficult and forced to buy 2x modules now? =(

I was thinking about this too. The pic below clearly shows it. The modules are "siamese twins"  How would they do it for the 3-module units that we ordered ?  |

I just got 2 4-module Avalons with power supplies. the units are smaller. I set them at 350 and they are doing 110MH/s each. Not sure if I should change firmware as it is 20130723
Any idea how much power each Avalon is using now? Seems like overclocking to 350 would exceed the capacity of the installed 850W PSUs, unless you've thought of that already and upgraded to PSUs with higher wattage? |

You are correct about the total number of cables.
My point was that the black PCBs on top, the ones that the flat and power cables connect to, used to be 1 per module.
Now they seem to be conjoined, thus you have 2 modules sharing one PCB, as on the pic.

Does this look like a lot of rejected shares?  Could it just be the pool? (slush) |

There's nothing wrong. DiffA/Time reveals you're getting 1533.3199 shares/min accepted. This is equivalent to 1149.9899/min on a 3 module Avalon. You're fine. Be glad you weren't silly enough to listen to Yifu's advice to forgo the included PSU. Order#54xx "processing".  |

I believe the twin PCB can be broken in two. There's a breakage line in the PCB, and all traces seems to be separated. |

It's possible those are users who just took delivery of their units, and haven't set the correct pool settings. |
