Sorry, guys. I've decided to cancel this auction as of now. I'm probably just as nervous about this auction as the bidders are since there is a lot of BTC involved. I think I'll just go back to tinkering with the jalapeno.
My apologies to the bidders, interested parties, and John K.
Auction cancelled. Do not bid.
Noooooooooo! just kidding. btw where did you buy the AVR dragon from, and how much did it cost? |

Can those purchasing chips go Taiwan Semiconductor Manufacturing Company Limited and pick them up directly?
Even if you manage to pick up the chips from TSMC, I guess you will get a huge wafer  Need someone (fujitsu?) to cut and package the chips though. TSMC packages. I think Bitsyncom mentioned that Fujitsu was packaging Avalons. |

From your website: 0.18 um (micrometers) /180nm (nanometers) die size custom design.  Maybe you meant feature size. Sorry, some typos here and there, will be fixed shortly. Thanks for the head-up. I clearly meant feature size. I'm not one of the engineers but i'm in charge of creating the text contents you are reading, so you may encounter some small quirks like that, the text will be fixed properly anyways in due time. EDIT : Fixed all instances of the typo. Cheers Awesome cheers |

850 W sounds like a lot for 3 hashing modules @ 350 MHz. This is at 120 V? I am at 230 V and my default Batch #2 units with the 850 W power supply (enermax) pulls 765 W and the units I converted to a SilverStone Technology Strider Gold ST1200-G run at 735 W (92% power factor) yes, 120V. There is a chance that my P3killawatt is off. I will verify with my FLUKE DMM. |

can anyone recommend replacement fans for batch one?
I am interested as well. These look like they can reach 4000rpm max. Will buy a couple in case one fails. |

So how hot is too hot?
I'm running my batch 1 and batch 2 units at 350MHz now. B1 seems to have settled on 47c for temp3, where B2 is at 52c now. Ambient temperature here is somewhat high (28c).
I have to place my unit right at the mouth of AC vent to make sure temp3 < 50C. In SW USA, top floor |

From ASIC README:
34:375
36:350
39:325
43:300
45:282 (default)
47:270
50:256
Okay so the timeout at 350MHz is 36. Updated that as well. Thanks. |
