Wait 'till BTC hits forex.....  and people get to invest in BTC via IRA.... oooh boy..

I hear the figure 30PH/s tossed around for this coming January.  Then to stay current we need to buy 10x the hashing power we have now.  Ouch.

more likely is BTC going to 2000usd!

If the powers that be go to adversely effect BTC, aside from having Washington DC make it outright illegal, they'll target BTC stability, pump and dump punishing investors again.

BTC value ≠ difficulty, although that seems to be the trend.  Anyhow, I digress.  We need to wait till the market stabilizes, it's too risky to buy/pre-order any ASIC right now.  I am almost certain any ASIC bought today, will see very little to no ROI by the time the device gets to your door and/or after you mine back the initial investment cost.

Forget about BFL's Monarch, given their track record.. it won't be released till Q3/Q4 of 2014.  By then, it's like having a Jalapeno of today... or worst.

ITs that kind of twisted reasoning that may lead to 30PH in January. And will then cause people like you to go out and buy 10x more yet again, ignoring the fact mining is a zero sum game. When will people understand buying mining gear simply isnt going to be profitable for the next 6 months at least, and if/when it ever becomes profitable again, it will be with razor thin margins for those with the cheapest electricity.

That said, 30PH in January is likely exaggerated, unless Im underestimating the number of HF preorders and their manufacturing capability.

most likely they will manipulate it for a rinse & repeat cycle like they do with silver

I look at the size of the thing and the projected hashrate and think it's going to get too hot.

I pray for that day.. lol..

I also pray for some of my altcoins to go up in value.. even if they hit .25c/usd rate.. I would be debt free haha!

to stay current, you need to double the amount of your miners with every difficulty rise

Starting bfgminer as described (of course I "q"uit the original cgminer first) results in a Segmentation fault and the TTY settings broken and a cleared screen.

Code:

opkg install gdb
gdb --args ./bfgminer -S knc:auto -c /config/cgminer.conf -T -D
run

... wait for the crash ...

Code:

I had been in direct contact with Luke-Jr (thanks for your time!) and it looks like he could find the problem and
fix it. I think re-installing bfgminer from the GIT repository will fix the problem (if anyone else did experience it).

I made some tests (using a binary compiled with debug symbols - I must re-compile it) and it did work for 1 hour.

As some questions did pop up using bfgminer, I switched back to cgminer.

Luke-Jr: Can you give us some more ideas about how your software works with a KnC miner?
The old cgminer (or is it some other task running in background?) is disabling (and enabling) cores with too many HW errors.
This can be visualized using that BertMod utility.
bfgmiger is now doing this task by its own. You can see the number of active cores (2*4*48=384 for a Saturn) in the status
line. It looks like you can manually "enable" disabled cores. Will they also be enabled over time automatically again?
Is it possible that the BertMod statistics don't match the status of bfgminer?

My DIE 0 is the one that always had been warmer and the one that starts to disable cores (without very good cooling).
Using bfgminer you can see very good that this DIE has 7% HW errors compared to 2% of the other DIE 3.

The effect of a fushwork is still a big impact on the hashrate. I can not really confirm that it's better than how
cgminer is doing this.

Luke-Jr: Is this a general problem that can not be fixed due to the nature of those multi hundred cores?
From your programmers point of view, what advantage do you think bfgminer will have on those flushworks?

Alas, we're competing against technical investors with big bucks who likely held off, and perhaps a LOT of them.

Some bridges are better burnt because of where they lead.

I note your mention of good cooling.  I mentioned in a post how having fans on the sides of the module when removed found the voltage and current going up on the cores and the few iffy cores came back and apparently stayed back.  I forgot to mention one other thing.  With the fans away I could reach in and test the temp with my finger.  Thinking I had forgotten to try and remove a cover of a VRM when I was putting tantalum caps on the 12v rail, I considered that if they are snap on tops, heatsinks, then taking them off and putting heatsink compound might be possible but then maybe one just wasn't down far enough and since I could reach the VRMs I pressed down on each.  The die with the iffy cores still runs more current than the others but is 100%.  Maybe it wasn't the fan removal but the pressing down on the VRMs' tops.

Edit: I made sure not to press down too hard as flexing the board could break solder joints at the Ball Grid Array points of the ASIC.

I think one possibility is that in time we will all see that buying ASICs won't be anything more than a money pit, much worse than now.
The prices will drop, to a point...then there may come a day when ASIC manufacturers may see  that returns mining those rigs beat selling them ...since they aren't paying RRP but cost price. They won't need to earn 7k to balance a Jupiter for example...just more than it cost to produce which will be a lot less.

Who can compete with that?

They need us now to fund the dev period, but maybe once they have the funds or speed stalls for a while that won't be important.

Yep, if I ever bought from them again I expect the outcome would much the same as Lucy holding the football to be kicked by, who is it, Linus? who ends up flat on his back.
