I had one suddenly drop 16-18V out the pci-e power rails and cook a 5970. Otherwise it was fine.

dich 12.3 and go back to 12.1.

Even batch one never updated past payment completed. This order will probably never say anything other than processing. If you see that you are good to go. The next update you'll probably get is a visit from the yellow or white truck of happiness or a delivery slip in a month or so.

The best thing would be to add fans at the back and do push/pull and just put in a simple diverter for the air. Of course filling the 4th slot with another module would be ideal.

You need fast memory and a fast cpu, there's a magic ratio. You can get ~800Khash. FWIW most of my 5970 puke running LTC mining.

so, seriously, what IS that in there for? To force air through heatsink. |

It won't have the memory to hold the blockchain. You'd have to mine with a pc ( getwork to solo bitcoin is going to kill it, need stratum or gbt )or something like p2pool or with a pool that mines shares/earnings to your address.

It's a PC power supply the 5v and 3v rails can't carry much of a load. The 12v rails are where the power and efficiency is. From what nzhang has said they re using the 12v rails and dropping it to 1.2v with dc to dc conversion. It's more efficient at 220v than 120v.
It was stated that they were using antec 650w? power supply. The 4 pcb version had an enemax revolution 1000w unit.

I placed, an order and it said I don't have to pay through walletbit. Is there an address on the Avalon store I am supposed to send payment to?
When I click on Pay for order on Avalon Store it takes me to walletbit.
Below the wallet bit login there's a pay without a walletbit account link. That gives you a bitcoin address to pay to with your bitcoin wallet. |

No government is going to publicize they have broken an encryption algorithm. Remember the Enigma machines? They broke that and relied on it for quite a while and went at all lengths to keep it a secret.

I find it amusing how everyone is bitching about efficiency when everyone here is still mining on GPU. I'm still running 20GH of GPU and it pulls a good 10 KW at least, not counting cooling. 10KW of ASIC, even a inefficient "first gen prototype" like what we have right now would be greater than the whole bitcoin network as it was pre asic ~13.5 TH.

BitSyncom, I recall reading where you paid $400 to get Jeff's unit to him.
Can I pay for the same service? I have $400 in BTC ready to send.
Seriously, mine with my machines for a few days to pay for shipping, hell if they had been mining since the announcement, you could have paid for a private charter jet for them all and bribed customs on both sides. |

Still if they can build one it seems to be they should be able to make as many as they want as the real costs for ASIC are development, not manufacturing. You are thinking this the wrong way. Yes, the cost for ASIC is in development, but the cost to put the stuff in the box sent to customers is in the manufacturing. Think it in this way. Lets invent some number from my hairy ass. Lets guess the development of ASIC costs in 100kUSD in internal wages for some competent design people and 200kUSD in NRE for the foundry. Lets also guess to buy and assemble the stuff put to inside each box sent to customers costs 1kUSD. You sell 300 boxes for 1.3kUSD giving you 390kUSD cash in hand. Now what you are going to do: If you manufacture 300 boxes it costs you 300kUSD. Your total costs are 100+200+300=600kUSD and your revenue is 390kUSD. Net loss of 210kUSD. If you only manufacture 2 boxes it costs you you 2kUSD. Your total costs are 100+200+2=302kUSD and when your revenue was 390kUSD you get net profit of 88kUSD. if you do not manufacture anything 2nd batch money is pure profit of 600*1.5kUSD = 900kUSD and with the 88kUSD from batch1 it goes near a cool million. If you start manufacturing 300+600 boxes your total profit from batches 1 and 2 combined is 90kUSD grand total. The only way somebody could net a million dollars is not to manufacture more than 2 boxes. Also there is a fact that very few people enjoy doing the manufacturing. Designing ASICS could be fun for some. Collecting incoming money could be fun. Being arrogant on forums could be fun. Manufacturing a huge number of boxes not so much. So why not do it BFL style and take as many orders as they can get? |

It would be nice if Batch1 got some communication too. When batch one had ordering snafus it was much more responsive. I knows it's a small group and that the effort is on making and shipping but I'm sure someone could spend a few minutes keeping the customers updated rather than feeding the trolls here and taunting Kano or Inaba. I'm sure you'd get volunteers to help if you needed it.

Right now, buy bitcoins. Unless you already have ASIC on order.

Still if they can build one it seems to be they should be able to make as many as they want as the real costs for ASIC are development, not manufacturing. Manufacturing is just logistics and china has that crap down, there's hundreds of companies there they could farm it out to if they wanted.
The only other option is they faked the ASIC and its a bulky front end to a Fpga farm somewhere on the net.

These are all first generation "prototypes" they are not super tested rugged bulletproof designs. they are all made by hobbyists and fly by night companies. The first gen machines are going to have issues. It happens. BFL has issues with their first FPGA singles overheating and causing problems. However the early adopters get to make a larger profit by taking the risk.

For this chip, at 100nm I don't think a QFN and vias is a problem. That's how they were all made back when the process was started. It's when you shrink the process and you start having chips with astronomical heat densities that you need better thermal conduction and BGA and heatspreaders come into play. Some of the current chips like the VRM on a 5000+ AMD or quad core chip are higher thermal densities than nuclear reactors per sq cm under full load. It's ridiculous. No we have exotic cooling and heatpipes and vapor phase cooling, along with water and other ideas.

This would not be proper airflow in a rack (and Avalon is designed to be racked). Strange, I have seen Server racks online with those kinds of configurations. (mostly 120mm fans) These fans you guys are looking at are crap. Server, rackmounts fans are substantial and HUGE. 120mm, but 2-3 inches thick with crazy high power motors. |
