check out Hboard out of production https://bitcointalk.org/index.php?topic=250249.420

There's something different about those chips...a clue perhaps to a question I asked on the OP [EDIT] Err. second post?

    Asic chip same inside but only package not same.

is it a tree instead of a flower? money tree!

Hi Dave,

Please put me down for a couple of "bad boards" too!

If they even partially hash they're still better than nothing. I used to be a Sr. E-tech & I have access to a full lab that we could hook it up to an o-scope & other fun tools.

[DyslexicZombei]

Hmm, of course I'd need an M-board to host it or it'll sit until the October shipment.

Any "naughty" M-boards not up to spec in that batch that just need a little TLC like capacitor swaps or something minor? Had to ask while we're on the subject. <Promise not to forget to discharge it first.    > I'll be more than happy to take that naughty board & give it a good e-spank.

Silently following, just want to throw down that I too would be interested in partially faulty boards.

[goxed]

Please count me in for some of the Bad Boards.

[arorts]

We all want faulty boards so to save the length of this thread it might be easier if only those who don't want faulty boards say so. :-)

Hmm.., so Dave is on a new venture?

www.davessemiworkingboards.com should still be available.

(if he hurries)

lol

So Dave... This response to bad boards was what I meant when I joked about there being a market for the boards if they only "added" rather than hashed.  Though obviously they would have to hash a little for most people to really want them.  Zero hashing boards I think would need a STEEP discount (and an EE degree ).

If you are looking for PSU to power up the Full Kit, you should consider using Server PSU's. They are dirt cheap and rock solid :-)

Here is good guide how to use them as an 12V power source: http://www.rcgroups.com/forums/showthread.php?t=1292514

It is the path I will take for my 400GH kits.

[P_Shep]

Hmmmm... thinking about this. The chips seem amazing!

[-Redacted-]

I think the moral of the story regarding bad boards is - you are probably able sell boards - H-boards - as fast as you can make them and as many of them as you can make.   Even just 10 Gh/s boards....

$500 for a pack of 3 naughty boards? (because everything naughty happens in 3's)

I'd hit pay that

Gosh, why did we work so hard to get them fully working?  We could have been selling non-functional boards ages ago!

Hey, I was only requesting halfassfunctional boards

That would still beat the competition in terms of delivery....

I'd buy halffast boards today over full-fast boards next month

[jspielberg]

The key is the discount..  No one would pay full price for the broken boards, but if you were going to junk them... Well, for a reasonable average GH/$, they would find happy homes.

The proto rig is rock-solid after 24 hours of running at the new chip.conf.  

These asics are curious critters - if you have a bad chip on a board, software will disable the chip in config.  This causes adjacent chips to see a little more power and therefore get a slight overclock.  For example most chips are producing around 1.5 - 1.6 GH/s actual nonces.  But some chips are at 2.1 GH/s.  In this way, even with some duds the full rig is producing 410 - 415GH/s actual accepted shares.  Even Slush stats have caught up and show average hashrate over 400G at the pool.

I think this is unique - it seems most mining hardware is rated at a certain hashpower, but true output is typically less than promised.

Aha, so desolder a chip per board sell it for profit.., and still have your full hashing power. Got it. hehehe
