True. In theory.

It depends on luck.

If you're unlucky before a major increase in difficulty and then equally lucky afterwards, you will have a net loss.

And difficulty will be increasing rapidly over the next several adjustments. IMO.

I would welcome oganofcorti to weigh in on that thought.

-- edit

Of course, if you are lucky before instead of after, then "the force" is on your side.

Oh. An "exchange". "already" you say.

And where is this exchange where I can buy/sell, please?

--

Actually, my question is rhetorical since I've already transferred all my shares to BitFunder and sold out.

IMO, 0.8+ BTC per share is about twice the 'proper' price.

And I recognize that is fairly open to debate. I made my assumptions and estimates for the next twelve months and made my decision.

Well, other thoughts. Not necessarily in the order to try them, just a set of more ideas.

a) Ensure the problem board is the only one connected by USB cable and the up/down cable is disconnected.
Also, as always, don't have any mining software running on the machine being used to run the flashing software.

b) Again referring to "Enterpoint board notes - DIP switches", page 8:
Switches:
1 - on - Not in Reset
3 - off - Programming Enabled
4 - on - Master
6 - off - Controller SPI Programming Enable
8 - on - Inbuilt Programmer - (only relevant when flashing the array/four FPGAs)

c) Toggle each of the switches back forth a couple of times. - Sometimes these switch blocks can get somewhat unreliable. I've got a switch on one of my CM1's which sometimes doesn't detect the 'correct' setting. And there has been at least one other person reporting this issue. Ideally, use an ohm meter to prove that each switch position is truly on or off.

d) 1) CM1 powered off. 2) usb cable disconnected. 3) Set the switches as needed. 4) power CM1 on. 5) wait two minutes - until it is *known* the device has 'settled down'. 6) connect usb cable. 7) try spiprog.

d) Prove that there isn't some other yet to be noticed problem inhibiting spiprog usage by flashing the known good board. If you can't flash the good board, you'll not be able to flash the 'bad' one either.

e) Get a compatible JTAG cable and use the xilinx ISE software to directly examine / flash the Controller and four Array FPGAs.

Option (e) is arguably not a sound financial decision. At *today's* mining difficulty level it would take two to three weeks of mining time for the 'restored' CM1 board to recoup the ~ $50 cost of the cable. At this point you might never hit break-even on the cable cost if difficulty rises fast enough. And that's assuming a reflash 'fixes' it. You have every reason to believe the board is mortally wounded.

Has cgminer, or anything else, 'touched' the ports before you tried spiprog?

Try:
1) reboot the computer
2) don't start any other programs
3) run spiprog again

Another thought. How old / what generation is the board?

If you got it after mid-September, it is probably 1.5. Older than that things / versions get iffy.

Find this doc: "Enterpoint board notes - DIP switches"

The switch definitions are not the same on all versions.

Regardless, turn switch 3 of 8 off and try again.
I.e., 1-on, 3-off, 6-off, rest-<don't care>

-- edit 1

NOTE: That is 3 of 8 of the two switch blocks which are mounted adjacent to each other. With the power and USB connections on your left those switches are 1 through 8 starting with the one closest to you being #1.

This is all in the doc I referenced above.

-- edit 2

Yep, I think page 23 of "Cairnsmore1 Manual – Issue 1.0 20/09/2012" is wrong.
Or at least not universally 'right'. 

Try this pattern on the switches next to the molex power connector:

x
x
    x
x
------
x
    x
x
x

Yes, something along that line.

But I'm pretty sure that one will not work with these boards.

If you search through my postings you'll find where I found one which works for me. (I'm sure you can find one cheaper than I did if you go through eBay.)

However, I do suggest you just try flashing the firmware using your existing USB connection before you go through the hassle and expense of gearing up to use JTAG. (I'm a developer, so I had additional justifications for the tool / toy.)

Enterpoint has given complete instructions on how to update / flash the firmware on the CM1's. Search and ye shall find.

Can only be done with a JTAG cable connection.

-- edit

But you might as well just try re-flashing it anyway, without bothering to check if the current image is corrupted.

Yep.

Charity is voluntary.

Coerced 'contributions' is theft.

This is Bitcoin. Not the Democratic Party of the USA.

I do sympathize with eleuthria.

However, he has no right to, nor has he asked for, 'taxation' on the overall community to cover his mistake.

It was a somewhat costly mistake. Been there, done that. Learn from it.

I don't think that is the case.

There are 200k shares in the ASICMiner, 'preferred', pool.

Just because they weren't sold doesn't mean they don't exist.

AFAIK, BitFountain owns those unsold ASICMiner shares - I think around 30k. As well as their own 200k.

The email below is ambiguous, at best.

Based on the "newlc", I'm assuming it refers only to Litecoin mining.

Hello Ozcoin miners,
The time has come to close this pool and move to the new DGM/PPS Pool at newlc.ozco.in

Thanks to everyone that has mined with Ozcoin

Yep. Just now showed up.

Now, along with everyone else, I'll watch to see how long before it hits six confirmations.

I have not received a dividend payment this week. (Got last week's.)

Yep.

I think it is the first time I've hit the ignore button on someone with such a low post count. 

Yes.

The original agreement needs to be adhered to or explicitly changed.
Via the originally stated mechanisms for such changes.

No, it does not "[have] to be physical work".

Here's two other possibilities.

1) For whatever reason, the software or firmware just isn't cutting it. E.g., one or more sets of hardware keeps dropping offline or getting 'hung'.

2) The chips / boards are failing nearly as fast as they are being deployed. Resulting in only about half or less of the first batch remaining operational.

Either of those hypothesis can explain why we're now seeing between 4 and 5th per hour rather than the 12 expected by now. In case one, they just can't keep them all cranking. In the second case, the magic smoke just keeps escaping.

I am not advancing either of these ideas as probable. However, with what we know, either is just as plausible as your contention of what "has to be".

-- edit

Just went to take a look at current status. Now at "4,221.70 GH/s". Down from the about 5 TH/s we were at for a while. That is more than just mining variance. Clearly shows that not all the hashing power stays up once deployed.

Yep.

We've all seen management demand that baby be produced in one month instead of nine.

"Just add more workers, I don't care what you're claiming the bottleneck is."

I'm on the ASICMiner team.     

It would be easy to run rampant with speculations.

Let's see what information Thursday's update, coming on Friday this week , hopefully, will provide.

That you do your homework.

1) What is your break-even point for power cost at BTC price and difficulty level?

2) How long, under what assumptions, until ROI is achieved?

IMO, the game is now over for GPU mining as it was for CPU mining before.

Unless your calculations show you mining at a profit with that hardware at difficulty level well past 60 million in two or three months, currently around 4 million, then make the sale, pocket the cash and consider you had fun while it lasted.

It is a sucker's bet to be buying new GPU hardware just for mining at this point.

Continuing to use existing GPU's, you might do OK for another couple of months. At current BTC exchange levels.

Yes, please.

This seems important enough that it should appear at the top of the web page(s) as an announcement.

I'm frequently checking my status.

I rarely read this thread. (And that announcement is now buried several pages back.)

My stratum proxy is now pointed as per your above request.

Regarding the "new_ui". Nice enough.

However, I don't see "Performance Charts", yet. (I assume they will be coming.)

I look at those. Often. Would hate if they were left out of the new design.
