I don't think a Raspberry Pi USB does well with an unpowered hub. The power that a Raspberry Pi USB port can supply is very limited. While it may have worked with 1 device, and the hub itself, adding devices will just drag down the +5V that the Raspberry Pi tries to supply to the hub. Maybe the Avalon is REALLY low current and it will all work just fine. I just know things get unreliable real quick when the +5V on a Raspberry Pi isn't nice and well regulated at 5.0 (or a smidge higher). I had a variety of reliability problems with a Raspberry Pi setup and a hub, and they all just disappeared when I supplied the hub and the Pi from an ATX +5v line. Fighting power problems is REALLY frustrating in my experience.
That might be a issue if it was a USB stick miner and getting power from it. But it seems to work fine with a unpowered with one perfect. Hopefully in a week or two I have the more units and can confirm it works fine with regular non-powered usb hub. But if needed I have a few from the ASIC Miner stick miner days in my parts I can use.

They promote these miners with "Avalon4.1 4.2T Suite". Okay, 4.2 Th.... They also write: "Mining speed can reach 1.3THs". So 3*1.3=3.9 Where are the missing 0.3 th/s?
So in the best of all cases, you get 3.9 Th/s for 6 BTC. But still have to buy PSUs. Has anybody ever reached 3.9?

Okay these miners are all about quiet not hashrate. I can get as high as 1.2th but like spondoolies sp20's higher clocks burn more power per gh. So if you have free power and want to overclock them tell me I will do a 2 unit 6 hour overclock test for you. I am at 1637 and 880 watts for 2 units as sound is my absolute most important issue. next is power I am at 0.5375 watts a gh here I am on a freq 20.94 2 unit under clock ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fimagizer.imageshack.us%2Fv2%2F1024x768q90%2F911%2FWriH9G.png&t=665&c=ro0qLLxqvdIMZw)

But never mind, the main issue is that the house has four doors.

So just like the sp20 power use jumps faster then the hash rate. I was 1600 gh and 860 watts = .5375 watts per gh I am not sure I want to push past the present settings. note I cranked the volts to 8625. gear is still pretty quiet Now 2308 gh and 1600 watts = .69 watts per gh ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fimagizer.imageshack.us%2Fv2%2F1024x768q90%2F538%2FSeb2Ix.png&t=665&c=Ghj47nj257JXdA)

Quick shipping from Ehash. Now I am up to a set of three. It is working good it appears by just plugging them in usb hub. Have some testing to do so I can add more info ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

It's a non-powered hub. So far it seems to work great with the 3 of them.

So far the 2 new miners are working great with the first one. Below is a image of the three running a little underclock.

yeah that is a good speed mid 900's > I am doing a speed test on my 2. these start pulling a lot of power on the higher clocks. note the volts are set at 8750 that is 9.375 percent over stock of 8000 I just wired 1 socket for 240 volts about time. I am using an evga 1600 p2 for 1 unit and an Intel server psu 1200 watts at 240 volts along with 94% efficiency. It is still not too bad for sound, I think I could squeeze out 2650 or 2700gh for 2 units ,but the power cost makes it a dumb thing for me. I know some people want to max gear due to free power. look at my errors and my temps these can do more then 1260 each like they are doing here. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fimagizer.imageshack.us%2Fv2%2F1024x768q90%2F908%2F2h4Wyz.png&t=665&c=e5C3FcWu8KzWLQ) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fimagizer.imageshack.us%2Fv2%2F1024x768q90%2F661%2FkyH5dT.png&t=665&c=bWd2jQqNQVHMDw)

That is a nice speed on 2 units. I to can't make it work out with price of electricity. I was able to get all 3 of mine on a single 110 circuit with underclock.
I'm using gold power supplies, but still very happy to get it all on 1 110 circuit. I am looking into changing a lot with my summer mining area. Still working to add airflow, I want to run this summer without using AC on miners.

Yeah I am losing money or breaking even, but I will do it for a day to help people get an idea of the top end limits.

Nice findings. Looking forward to your results on the 1.2TH area. findings....Could the Avalon be the one that should be standing next to my SP20 `s ?

Been testing 3 for a little less then 24 hours. So far running great as far as stability. Again I am using a Raspberry Pi to control them, it is working out great.
More to come I have been documenting this from unpacking till now.

Three Avalon 4.1's so far happily mining together. I would consider very stable at this point. Need to add some lighting I appolgize it's darker then I originally thought.
