You might be able to get 5% more out of them using glasswalker's flash.

Might not, also. And you should consider ROI on that for the down time required to perform the flash.

And, one of mine once failed to flash successfully. I had to buy a JTAG cable to resurrect it.

Since that, I've been merrily hashing on them since last September.

As with all things, YMMV.

cgminer does not support glasswalker's dynamic clock firmware. AFAIK.

I have a couple of CM1s and also have found that MPBM works better with dynamic clocking control than BFG.

Currently running both the CM1s and a BFL single clocked at 800mh/s using MPBM on a Raspberry Pi.

Once had an uptime of over a month. A week at at time is common place - and that's merely because I've been mucking about in the server room for the last couple months. (New UPS, re-arranging equipment, etc.)

Actually, yes, I can.

You have those five as payment for doing the group buy. Which includes distributing the goods.

You have not completed the work for which you're receiving those five.

Work before play.

Say wut!?

Minimum buy qty is 300 but they ship in lots of 200?

I'm so confused.

You do realize that difficulty is likely to be at least 5x what it is now by late this year don't you?

So far there has been no delay.

Perhaps you did not do your homework before making your commitment?

egads!

The plaque which ends our society (see "The Stand" or "The Andromeda Strain") begins due to BitCoin hardware shipments.

 

Well, it is still another six to ten days before friedcat is expecting to receive these things from manufacturing himself.

Everything I've seen so far is that ASICMiner has only accepted payment when they have goods ready to ship.

A refreshing change of pace from some other companies in this market space.

<sigh> Much as it pains me to say it, I agree with this because it gets the mostest out the fastest.

I fully agree with this. However, nothing was stated in the OP, 'the deal', about shipping priorities. And I hate any changing of the rules mid-game. Therefore, IMO, arklan is free to ship these in any order which floats his boat.

BTW, ASICMiner just sold 140 more blades. So that's about another 1.7th coming on line, about 2% addition to total network hash rate, just from that sale within the next one to two weeks.

Interesting requirement to provide the shipping address via a PM.

That effectively gives bitcointalk.org your full identity rather than just the email address which was required at registration.

I will attach the heatsink, if they come separate, to mine.

Cooler electronics tends to be happier / longer lived electronics.

My vote is that arklan does not test.

Actually, a half dozen of those.  

On two discrete USB buses / chains. (Since the USB limit is 255 devices per chain.)

And each of those panels would have to be able to supply 200 watts.

For approximately 1.1 kilowatts in total.

I think that would have to be called Uber Serial Bus.


-- edit

Although, that would be about 132gh. (Discounting any USB communication overhead / losses.)

Roughly equivalent to 10 ASICMiner blades.

Which, coincidentally enough, would use pretty much the same amount of electricity.

(I just used 440 as a convenient round number for those calcs.)

That would be a *lot* of wall warts powering those hubs.  


-- edit

And just thinking about that a bit. That would also be a lot of USB communication. Pretty sure it wouldn't exceed the USB bandwidth specification. Not so sure about how much little back and forth traffic USB can realistically handle.

Well, $100k USD equivalent in BTC is liquid. I.e., easy and worth walking off with.

Four hundred odd little devices which can't be readily fenced on 'the street', not so much so.


arklan, not saying anything here about your trustworthiness, just pointing out the significant difference to Blockhead.

Won't be an issue to me. If you come out nicely ahead, I approve of the entrepreneurship.

My initial thought was that for payment of three devices, about 6btc, you were committing to a lot
of work which would on an hourly basis probably come out to a lot less than minimum wage.

However, if the above numbers hold you will have done ... 'OK'.   

And there are two big assumptions in the above. The assumed 0.05 per device for final shipping
and that no assessment is made at the import / customs point.

My 'back of the envelope' calculation below is based on the Google Spreadsheet. And, of course, assumes that everyone with an order pays. If not, then the numbers just scale down some.

Taken when Google Spreadsheet was at Total: 434


 2.1013   Price Paid ea.
 431      Num paid (arklan doesn't pay for his three)

 905.6603      Total BTC paid
-18.113206   Escrow 2%
-846.3      Pay to ASICMiner for 434 units (431 buyers + 3 for arklan's fee)
-21.7         aggregate shipping to buyers at 0.05 each * 434
         ("something like .05 btc per usb stick maybe")

19.547094   BTC collected beyond itemized / known expenses

-- edit - Removed an opinion and left only the calculation.

Possible, of course. But IMO unlikely.

At the current price there really isn't a pure fiscal justification.

Resale at viable mark-up makes it even less worth buying.

Anyone buying a batch of these for resale is making quite a bet.

Accounting nightmares.

John K. is doing escrow. For a fee.

Dealing with that kind of accounting, refunds hither and yon, is not part of his commitment.
