Well Avalon charges $9 per chip (AFAIK someone correct me if I am wrong) and that is obviously inflated 1000% or more over silicon cost and that cost will sink like a stone.  So you could remove $2400 from the system by assumming the price of chips in bulk drops from $9 to $1 to remain competitive.  However my point was that even doing that looking at an Avalon, the balance of the system cost (PCB, heatsinks, assembly, DC to DC power supply, power distribution board, controller board, even mundane things like fans, power supply, and cases) isn't being marked up 1000%.  Excluding the cost of the chips you couldn't drop the cost on the rest of the system 90%.   So while the value (and price) of older chips will indeed fall like a stone the BOM (balance of materials) cost will subdue the price drops.

On a related topic this is why I believe those that think $1/GH complete miners are reasonable are just silly.  Still in full disclosure I own miners, shares, and pre-orders with multiple companies but not Avalon so I may just be biased.

I updated the post.  The product in question is the one available from the person I was responding to.

I am comparing the product they have available for order.  If they have a bitfury based product I would have used that.

Still maybe I wasn't clear.  A 4 board avalon uses 300 chips correct?  They are currently excessively marked up ~$9 ea so lets pretend the price was dropped to ~$1 per chip.  That would remove $2400 from the cost of the system.  It is easy to see that either the seller has massive profit margin (I doubt it since given the Avalon uncertainty they would prefer to see out of pre-orders) or the BOM (balance of material) on that "huge number of low powered chips" contributes significantly to the overall costs.

Lets look at GPUs.  With crossfire (some software magic) 2 GPU can split workload.  A 7990 is essentially two downclocked 7970s internally crossfired.  AMD doesn't try to make a monster single chip 7990 because rightly so there is point where you get diminishing returns on larger and hotter chips.  However cross fire isn't limited to two chips.  Why not make a single chip of reasonable middle range computing power.  Then you could put one chip on a board and call it a 7950, two chips on a board and call it a 7970 and 4 chips on board and call it a 7990.  One inventory part, 3 products.  There was some research into that (and I am sure AMD/NVidia still are) but having a single unified chip reduces the post-fab assembly production/yeild issues.

All I am saying (now in an excessively verbose way) is there are pros and cons to each approach.

Take KNC for an example they use 4 chips on their top of the line model.  Aha! See even KNC is taking the "more less powerful chips aproach" leaving only HF taking the path less traveled.  Except not quite.  KNC chip uses roughly the same power as HF.  The need to use 4 chips is simply due to a less efficient architecture*. KNC isn't using 3, or 2, or 1 chips because at 250W they (and HF) are reaching the limit of what can be cooled realistically.


*Before the KNC warriors attack me this isn't an insult.  Just comparing reported specs.  It may be that KNC is overly cautious on power projections and HF is overly optimistic.  It may be that KNC decided they could make a more efficient chip but time to market was more important and 2.5W per GH was "sufficient".  Whatever the reason my point is that KNC needs 4 chips to acheive the same hashing power not because they are taking a "more and cooler" aproach but because that is where they maxed out at.  If they were 4x as efficient they would be using a 400 GH/s chip as well.

Not for most PSU.  The quick and easy check is to look at the PCIe power cable.  Does it have two connectors one one "string"?  If so then using a splitter doesn't really do anything


The connector can handle more current than is needed so it is just a question of "can the PSU push enough current to the connector".

You could use a splitter to connect the connector 1 & 2 in diagram above but the same amount of current is flowing through the cable regardless.  If a board pulls 20A then at the point marked * it will have 20A of current regardless of if you are using a splitter or not.

So for four connections it would be something like this


Each set of wires is carrying no more than 1/4th of the total load. So 1000W / 4 =  250W / 12V = 20.83A / 3 conductors = 6.94A per conductor which is below the limit for both the wire and the connector. 

$6250   700W       85GH/s      8.23W per GH   $73 per GH
$5600   350W      400GH/s      0.88W per GH   $14 per GH

Yes unless what he means is a dedicated offline machine used for nothing but generating the authentication codes.

@glon Well depending on the site you may have options.
If the site still shows the authenticator code you can print it after the fact.
If the site allows you to change the authenticator code you could change it and in doing so completing the steps above.
If the site allows you to disable the authenticator code then do so and then enable it completing steps above.
If the sties doesn't allow you to change, disable, or show you the authenticator code you probably will need to request the admin remove authenticator from your account.

Which isn't a premine.  The topic wasn't "is it ok for developers to mine their own coin after launch"  if it was then Satoshi post launch activities might be relevent.  Still you knew it wasn't a premine yet included the (pre) anyways.  It is false anyway you try to spin it.

Good company.  Had some problems with the local delivery contractors and they made sure everything was done right.  I only wish they accepted Bitcoins.

Still false even though I liked how you try to spin it as good thing. 

I doubt it.  The order page and details provided by BFL have consistently said PCIe.  The photoshoped product photo is a reference GPU fprm factor with a PCIe connector (although it is x16 not x1).  What would be the advantage of PCI?  You got a motherboard from 1999 you want to bring back to life?

Insurance (optional):
$5 per shipment plus $5 per bar. (i.e. $10 for 1, $30 for 5)
For more than 3 bars Registered Mail is required (our non-registered insurance contract has a maximum claim of $5,000).


Terms:
Payment is in BTC only based on Bitstamp exchange rate at the time of payment.  Insurance is offered, if you opt for delivery without insurance you assume all liability for lost/stolen mail.  Insured packages will require signature for delivery.  Uninsured packages will be sent with no signature requirement (let me know if you would prefer signature required).   Shipment will be in padded envelope inside flat rate envelope securely double taped (all seams).  I have only lost 2 of 500 mailings using flat rate envelopes so the risk is low but I leave the choice of insurance up to the buyer for shipments up to $4,999.  For shipments $5,000 or more registered mail with insurance is required.  If paid (6 confirmations) by 2PM it will ship same day, otherwise will ship the following business day.  Tracking number will be provided.


Escrow:
Honestly I don't think you need escrow given my trading history both (personally and running TC, LLC) but then again I guess that is what a scammer would say.  If you check out my history and still want insurance my terms are: sale price is 1% higher due to my risk, you cover all escrow fees, escrow agent is someone I trust, and shipment will only be sent insured.  I would recommend John K for escrow.


Other:
Please no low balls offers.  I am not desperate to sell.

I would put that in the upper 50% of "analysis" done on this sub forum.  

I have an appointment to sell a kidney so I can buy more bitcoins.  I figure when they go up 1000% I can just buy a replacement one.  Pretty much a no brainer at this point.  My only regret is the blackmarket doctor refuses to pay in Bitcoin otherwise I would be helping the Bitcoin economy too.

0.  The genesis block has the quote proving the date and the dates of public code release and blockchain timestamps support that.  In the first year Bitcoin wasn't very popular.  More people "could" have mined it most simply didn't.  Satoshi got a lot of flak about his system being unworkable in the early days.  Many who knew likely didn't mine because it seemed stupid.  BTW Hal Finney IIRC reports mining one of the very early blocks (like #200? correction it was around block 70 seem below).


Say I launch an alt-coin today. Full source code, compiled binaries, no premine (even genesis block unspendable), high starting difficulty so early blocks take LONGER (about 20-30 minutes per block due to low hashing power).   Now say most people ignore it because they think the idea is stupid and can't work. If it became popular a year later would you accuse me of "premining" it because others couldn't be bothered to download the client and try it?

The claims of a pre-mine are never supported.  They are just slander to provide moral equivalence for those that do.

Use pywallet and extract the private keys.  You can then import them into another wallet.  You don't need to import all the keys just the ones you get regular payments on.   I would save a copy of the encrypted wallet.dat and an encrypted copy of the pywallet dump offline just to be safe.

The power of limit orders.

I would say it is next to useless. Watercooling isn't a magical fix.  

For watercooling to make sense it should be economical, improve cooling, and be used on a device which can significantly expand its power consumption.
What is the computing power per waterblock?  You want those lowest waterblock cost in terms of $/GH and that means larger hash power chips will be better choice.
Is air cooling acting as a limitation?  Chip temp, size of heatsink, noise of fans.  If the device is only warm to the touch with no air flow then water cooling isn't going to improve anything.
Do you have extra power to overclock?  Can you supply more power to raise the clock to benefit from the increased cooling. Increased hashing power out of the device offsets the increased costs.

USB miners fail hard on all three.


Better choices for exploring watercooling (from most benefit to least benefit):
Hashfast (uses watercooling. I wonder why?  See above)
KNC (100GH/s 250W ASIC and board can supply up to 320W)
BFL (not jalpeno)

No significant benefit IMHO:
ASICMiner Block Eruptor blades (will need very large heatsinks)
Avalon (will need very large heatsinks)
Bitfury (stock board has no spare current)
USB Miners (see above)

The above is a fan fiction.  It should not be confused with reality.
