I see nothing.
No miner.
No hashing.
Let us see what BFL customers are posting shall we?
Imperial Monarch overclocked to 1.6TH/s = 1100W -1200W draw
(or about 100A @ 12Vdc).
Feed through 12 (6+ and 6 grnd) 18-20ga wires to two PCIe connectors
(550W-600W per connector).
Sounds like a recipe for disaster to me.
Or at best, yet another circuit card re-design/shipping delay.
Adding copper to the power supply plane on the card fixes the
power plane overheating issue, but one is left with the issue of getting the power into the card.
Not to mention the heat dissipation of ~3600 Btu (per card) each.
Enough to heat a small well insulated house in a Minnesota winter.
Assuming an 80% efficient supply, current draw "at the wall" will be
~1500W or 12.5A @ 120VAC (one supply per 15A circuit).
Pretty much condemns this card to one per 4u rackmount case.
Industry standard for 45u-48u racks is a power supply of 4Kw-4.5Kw per rack
(thermal dissipation into/out of the rack is designed to match this).
This means 3 overclocked Imperials per rack. Pretty low rack density
(4.8TH/s per rack).

Could you please stop ignoring completly your customers and answer the
question? Will we ALL get a compensation after 6 month of waiting or it's
just for the first batch of customers and F*** the rest?
Answer the question or I'll have to ask for a refund. I don't want to receive
my miner at 50bil difficulty without any compensation. Because if you don't
realize that already, it will go up like crazy (especially when KnC starts shipping)
and let's be honest they will probably do it before BFL since all shipping info from
BFL is completly unreliable.

Adding more copper to the power plane is a trivial change.
The new boards will be in KC on Thursday (I guess that's tomorrow...
I don't even know what day it is anymore.) last I heard... I will have
to verify that when I get back.
As a side note, if you are planning on doing any overclocking or running an
Imperial, please be sure your PSU has 16ga wire for the PCIe connectors.
If you have a cheap PSU that has 18ga wiring, you are going to be a very
sad panda at some point I would imagine. The warranty will not cover melted
connectors due to incorrect wire sizing. Most quality PSUs should have 16ga
wires for their PCIe connectors.
And it continues on and on...
I am so deeply sorrowed I had to req. a refund because my 20k order has
become so worthless after delay by delay, its like someone whom I loved ,
took of without a reason. I know it sounds disturbed/sick. But it's true
and on...
I don't think there is any debate as to who the market leader is.
KNC released their 28nm device in october. They are now racing to complete
their 20nm chip.
Yes BFL shipped a crap load of 65nm devices, maybe more than anyone
else but they won't publish numbers to verify one way or the other.
As far as shipping this month goes, I wouldn't hold my breath. They might
get a few boards out to media people and developers by the end of the
month, but realistically they won't be into full production before mid next
month if all goes perfectly from this point on.
Here's the math: next revision end of this week (or early next)
At least a week of testing before you can commit to a design
At least two weeks before you can have any volume of boards in your hands
Then they need to get their assembly line going which will take some time (figure another two weeks.)
This puts us in the middle of July, and that's if thins go perfectly from this point forward.
I'd love to be proven wrong, but I cant see how its possible to get any volume before mid July.
and on...
The very best case is July. The realistic best case is mid July. If even
one single thing doesn't go perfectly we are looking at August before you see any volume.
and on...
I purchased my order in March of 2013 and I know we have been compensated
once already because of the initial delay (As I initially bought 6 Monarchs, $28K total,
which then turned into getting 6 Imperial Monarchs and 6 additional 600GH Monarchs)
but now because of this delay is BFL still looking at another compensation? I know Josh
stated they were thinking about MBGH but he wasn't sure if that route would be taken.
Is there another route that BFL may go Josh?
Feel bad for these people.
