Hi Dave,
I know this is an old post, but just needed to confirm something: the image at the link you included above shows 6 mounting holes on the PCB whereas the PCB in the picture in this link https://bitcointalk.org/index.php?topic=251966.msg2676985#msg2676985  seems to have none.

Which is accurate? I assume that the photograph is of a prototype PCB which predated the mounting holes, but I'd like to know for sure. Thanks.

Yes, that was the very first prototype board, only a very few
were made. Later H-CARDs have mounting holes.

In fact, only the very first two cards were ordered without mounting holes.

Thanks for the clarification.

  Please leave BF boat alone and go back to your Avalon boat please.

Wow thats kind of dissapointing, I was hoping to chuck them outside for the winter. Does the default hardware and/or software allow any overclocking to compensate ?

Keep in mind that putting them out in -5C weather doesn't make the chips run at -5C.  They're still generating heat...

[dben428]

For those of you planning a cooling/fan/enclosure system - BitFury reports that the chips have an optimal operating temperature range of 45C - 50C measured on the package.  Cool them too much and they actually don't perform as well.

Do you think we need an enclosure of some kind for heat management or will we get by just fine without one? I was planning on just sitting a fan next to it, should it be needed.

Stick the test unit in one of these so we can see what it looks like...

I'm already on both boats, and I don't jump ship unless it's on fire. I've done and jumped from BFL's ship long ago.

This is all Tytus is doing and its working fine, but yes you will want a bit of air movement.

If you clock it up a bit in software, you'll definitely need fans...

Wha?!  I let something slip?!

I really hope someone constructs a little cheap Bitfury powered ASIC, c'mon let us "less fortunate" people get some proper stuff! Im sick of running my screaming gpus for ~1gh

I see what you did there ....

Before anybody mortgages their house on more boards or cancels their super secret OC board project...you can only tweak clock rate in software by about 3% and it costs you a lot of wattage...

Intron is designing a two-chip USB miner - he posted on Bitfury's thread: https://bitcointalk.org/index.php?topic=228677.0

Surely someone will make these when the design is done...

any chance of component tweaks between the august/october kits that might improve the situation? you know, lessons learned, etc..
