DVB allready started to build up the team for GPL AVALON Watercooling elements production. I see heat as a major problem for ASIC devices in general, this heat probably causes the errors, more noise and higher power consumption, aswell the need for the restart. We will investigate, with a thermo camera, as soon the AVALON trade-in harware arrives here in Switzerland. https://bitcointalk.org/index.php?topic=101559.msg1493823#msg1493823( DVB is a DEVCOIN (DEVELOPERS COIN) based and we guys use for development devcoins in between us. Jeff or BitSyncom: can you make heat pictures from your AVALON? It will show us the heat distribution among the device. BitSyncom: i guess your shop system will be fixed soon, and we gonna be able to make the trade-in order today  Thanks Icoin I can do thermal imaging of my units when they arrive. I'm in the first batch expecting them soon. That would be great. |

There is an onboard DC/DC module that converts the 12V to 1.2V or whatever core voltage the chips are running at, along with whatever they're using for IO.
Yes, but what I meant was that it does not effect the "expected at the wall = 72W" number. Like the usage of the fan, the AC/DC power adapter loss, it is included already in the "at the wall numer". |

Still having some amount of reliability problems. Moving the miner in the office helped a great deal. However, still seeing machine restarts for unknown reasons (note: must ping support, inquire about reboot logging).
[...]
Hi Jeff, I have noticed on you blog that "The miner is currently running on an already loaded residential house power circuit, while sharing a Back UPS ES 550 with another desktop machine. " You probably know that your UPS can supply only 330W of load on its "battery backup" four outputs (the upper four ones). So maybe you connected Avalon on one of the four lower, "surge only protection" outputs. These outputs do NOT protect against transient-faults/brown-outs/sags events, so if you experience these in your home, then although unlikely, there is a slight chance that your Avalon unit becomes confused. I'm also curious about the USB hub between controller and ASIC modules, what's its quality/reliability and how it's powered. Good luck! |

He did originally, but not now: After 30 minutes or so of mining, the lights in my room flickered, UPS's beeped and complained. Because of some stupidity (plugged into 'surge-only' side of UPS), the miner restarted as well. After some reconfiguration, this problem was solved.

Id suggest either ditching the ups, getting a proper one that's 1400-2000VA or getting a line-r to filter the power.

since a an APC BackUPS ES-550 can only supply 330 watts (I have 2 and can can confirm that spec, its also posted online), plugging a 620 watt Avalon into the "surge only" outlet is correct - ie, use the unit only for surge suppression. if its plugged into the "battery backup" outlets the unit will likely just shut down when presented with that kind of load. Aseras is right, get something more substantial. at the kind of coin that thing is cranking out right now its almost certainly worth it. needs 1100 VAC (650 watts) at least, so 1400 VAC (820 watt) unit is reasonable. |

And right now, the miner is in a strange state where the controller (running Linux) and cgminer are alive, but fans are not running, and no work is occurring: When they finally release sources, this should be pretty easy to fix. |

Continuing to see restarts. Restarts result in resumed mining, in all but one case. In the "one case", the miner was accessible via web and cgminer was alive, but no work was being performed.
Yifu does not think heat is a factor, but speculates that other software components may be at fault.
Switched from slush to BTC Guild for the "vardiff" feature, to reduce network overhead. Eligius also just deployed the "vardiff" feature. This feature will be crucial for ASIC miners.

In my post I wanted to say something like "you probably connected into surge because backup output is not able to power it when power fails". If it's plugged into "battery backup" it will work fine until there's an outage or sag. In that moment the APC will shutdown its "backup" outputs and start to beep. As you said, more substantial UPS is required. |

BFL's single uses 72W at the wall, there is no ATX psu or DC/DC or extra for fans etc, just the host usage to be added. All speculating of course coz it ain't alive yet, but it is definitely no 620W, or 108W.
Yes it's all speculation. At the moment BFL is paperware which uses no power at all and produces not a single hash. Let's wait if they manage to release an ASIC product at all and after that, let's see what their power and hashing values are. At the moment Josh started with his pre-delay anouncements so don't expect a release soon. Back to Avalon, will they open the source code or at least provide the sources to their customers? |

Good news. Mining on BTC Guild with vardiff seems to have dramatically reduced the restarts.

Have any other Avalon user's checked in yet? Network has rate is up 1.5Ths/s, yes I know that's an estimation. |
A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?

Which cgminer version are you using? For stratum Im using the latest xiangfu openwrt solution with cgminer 2.10.4 running 27 icarus and my rig is constantly restarting, before update was using cgminer 2.7.5(non stratum) and the 703n was more stable. edit: Im read the review and confirmed it is the *same* version! What changes did you make to reduce the restarts? |
