was wondering how long it'd take people to notice ( and more importantly share the constant that we've released on github.) the number you are all aiming for is 450  of course, that's not really possible on just air cooling. |

You mean is possible to hit 450gh/s no kidding? not possible just on air cooling, you need heat sink plus liquid cooling? |

Do you think that the batch 1 design power distribution can manage the increased power draw at those speeds? |

As I recall, I remember telling you to try 90+ gh/s this morning.  Congrats man. And yes I believe 100 to 120Ghash/sec is attainable. Just make sure your A/C does not auto shutoff because it sense's your "Room" hits X ammount of degrees target. Mine did. :/ All is well. |

What is the chip capable of 350 Mh/s or more?

My quick math (could be wrong) estimates the Avalon should be able to hit 105-115 Gigahash/second at ~450mhz clock.

originally at 282mh/s overclock to 450mh/s is 62.6% increase?

I've got a feeling we're going to see some interesting K16 cooling solutions being created to get more than 4.5GHs out of each unit...

Psst... ask Zefir... he has a design I believe that will be shared open source for a water block. Given that the Avalon seems to be right as rain with some great numbers should be great for Klondikes. |

Has anybody got to know yet how the 300 Mhz boundary limits of the Avalon work and how to trick it ?

So if anybody would be interested, tell me. I'm sure there will be lots of interest. I just e-mailed the plans for a water block posted here to a machinist I know to see if he can build them locally but I would pay good money if there are any other options out there. |

What I find bizarre is that Avalon chips are able to hit 450Mhz with liquid cooling on plastic packaging. What then would these chips hit in terms of clock if they were packaged like BFL's? I can't help but wonder... And gen 2....will be....worth watching.... |

Have anyone tried to completely submerge Avalon into mineral oil? That works very well for desktop computers.
Fluid would be too viscous for the fanz...  I've got a system that's submerged in mineral oil (quad E5-4650). Transformer oil to be specific (lower viscosity, higher flash temps, mostly synthetic, no PBAs). Fans don't really care, although that's not the primary circulation method (pump). might try putting my upcoming BFL units in mineral oil too.  |

You are a clever, clever man. What is the limit when we approach these speeds, the chips, the boards, the power delivery (ignore PSU) or the cooling? |

How did you overclock it in the first place?
Thanks,...

Good idea, transformer oil must be better for sure. I want to setup some cooling solution for miner while its not delivered yet. Do you use some sort of a radiator to cool the oil itself? I would not be comfortable with tank full of overheated oil in my room  |
