I've been asked to make a water cooling block for these, not sure how it will work out with the via's but it should give much more even cooling. With the way the boards are laid out it should also be fairly straightforward to cool both sides of the chips. Waiting on dimensions atm, should have it together fairly soon.
It would be interesting to know if the blank space behind the chip has traces or if it could be drilled out. If you could make direct contact with the pad underneath you could cool them far better. |

What I would at least like to see in the next batches are better use of forcing air in the fins of the heatsinks especially when adding more modules.I bet it would decrease temps by 5 to 10 degrees which would allow better overclocking.It should also be a more push pull fan design since the module heatsink is so long.
I actually agree, They should have probably have gone with a large 280mm+ fan assembly. (IMO only) Edit: Push/pull would have been better than what they did. I have to agree. I wonder how it will fare in summer to be honest. Jeffs machine is having issues. Some say it is heat related and other say it isn't. I wish the guy with the thermal imager (Aseras I think it was) would get his machine soon. Yep, that's me, and I am waiting. I can't wait to get mine and tear it open and look around. I can't help it, that's the scientist in me. ( I work for a very large university ) |

So how many people pre-ordered a batch #2 and probably loses their money?
Well you mean because of difficulty increasing enough to make the machines never break even or turn a profit long term? It's not a scam. The fact that 2 or 3 exist is proof enough, if they can build a few they can build hundreds, or thousands. The chinese are masters of reproduction. The real question is, is Avalon team financially sound enough to make it happen and turn a profit somehow to keep the investors and customers happy? If they wanted to run a full scam they wouldn't make batches, it would be open season and they'd just take orders they couldn't fullfill for months like BFL has done. Right now they have a goose than can lay golden eggs, they just need to get them out the door faster. And they need to talk more. If it's one thing BFL does better its communication, even if its trolling and blowing smoke up peoples asses. |

Unknown on blockchain.info is not botnets, it's mostly other pools that were relayed differently. This has been known for a long time.
Botnets will stop bothering bitcoin when the profit goes away, or they find something more profitable to do with them.

If you want to know how the package from jgarzik traveled, then it's as simple as asking him the tracking number that was on the box and tracking that on the DHL tracking site.
I asked him, he didnt answer it. By the way, I thought there was way too much DHL tape on the packages that were pictured,
That's packing tape. Customs tape is white and red and says customs all over it. If you shipped a LARGE box from China to US by DHL Express and customs tore into it, it would look like this.  |

The problem is you can't cash out. If you cash out much more than 5,000 coins the market takes a dive.

Maybe it's just normal restart variance  Couldn't resist. |

Except if they shipped DHL or EMS as they said, it should take no more than 10-14 days MAX. Usually it's about a week.
I order stuff from india, china and all over the pacific regularly. Heavier and more complex than this. Customs usually takes 2-3 days max unless they are sending you a nasty-gram.
China and Hong Kong have shipping down. Western Russia, not so much.

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

I can do thermal imaging of my units when they arrive. I'm in the first batch expecting them soon.
where do you live ? (just curious about expecting time...) SE USA, Florida. |

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. |

So, it does not work with p2pool. right?
Just mined all night on p2pool. It looks like fixing the air flow/physical configuration solved the issues. No miner or machine restarts while I was sleeping, and while it was mining p2pool. (no p2pool blocks either, alas) Are you using getwork or stratum on p2pool? Did you try both? Any difference between the two? |

I ordered several units ( on my birthday ), patiently waiting their arrival. Did you ever try it in p2pool or with a high diff share? |

Just for the record, I was not paid anything to write a review. The 25 BTC was a donation-refund, and a review was not mentioned at all at that time. Months later, I was bumped to the front of the line -- again, without asking -- and they asked me to do a review. I was free to say "no" or ignore them at any time. I assumed the community would prefer that I write about the machine, rather than keep silent and mine. Maybe I was wrong? There are people here who wouldn't settle even if you dissected the machine. There's even some who would have you dissolve the packaging in acid to look at the die. On another note, with the package, did you get the tracking info off of it and look it up to see when and how it was shipped? What did the declare on the customs forms? How pissed off was the Dhl guy who gave it to your wife? |

Since they are taking only BTC:
- Do you first buy and than make the transfer in 1-2 days?
- How is the BTC needed calculated? Especially since it is fluctuating a lot nowadays...
Last time you had a order and had to send a wire or btc quickly. If not the order was considered canceled. Last time the agreement was at the time of purchase you are selling your btc for the current market rate at the time you do the transfer. If you needed a refund or whatever, they paid you cash back. |

Of course as usual someone had to mention luck and kill it.

@MrTeal
what is on pic. #4? is this facility WC? or this is ASIC?
It's a contracted fab, its whatever was running when they got a tour probably. |

I agree, my problems started with v10 also, and got worse with v11 - which also matches up with the beginning of the bad luck streak. It's just too coincidental me thinks........everything before v10 was grand.......but hey, I'm a noob, and I'm not kidding when I say I still have a lot to learn about this. But just look at that chart - something's wrong.
PatMan, still so sure something is wrong?  peace. spiccioli One does not even infer mentioning the L word. Even indirectly. Silence. |
