As I have said before, I believe that the only possible real solution is distributed pooled mining like P2pool.  I believe that some distributed pool will eventually emerge that will be good enough and attract enough users that it becomes the 'best' pool (however that is defined), and then the integrity of the bitcoin network will be safe for good.

In the short term, trying to pretend that some miners making a conscious choice to 'save' the network by choosing smaller pools arbitrarily is just self-delusional, contradictory, and will result in pools that are less responsive to the needs of miners.

If you really, really want to 'save' the network right now then design the perfect distributed pool.  Otherwise, make what money you can until someone else does.

The problem with p2pool is that for most its barrier to entry technical level is too steep.

I mean this is the instructions for setting it up in Windows: https://bitcointalk.org/index.php?topic=18313.msg712967#msg712967

And this in Linux: https://bitcointalk.org/index.php?topic=62842.msg734371#msg734371

Vs,

Change one line in your miner to point to elgius or two to point to most other pools.

I agree.  That is just one of many challenges for P2pool as it now exists.

If I have a crack at it will it work ok with my KNC miner?

Firmware 0.97 and up worked pretty well the last time I tried it.

The point of me sharing this is simply to show my excitement and proof that even a noob like me can make this work!

Officially, I cannot condone what you have done! you have voided your warranty.

No worries, I completely understood that I was voiding my warranty.

[2013-11-21 18:02:14] KnC: core 4-166 was disabled due to 10 HW errors in a row


On my upgrade board. Not sure how to handle.

Did you let it run for a while and heat up a little?

Dude....cores enabling & disabling is totally normal.....relax
Happens to about 5 of the 9 boards I have.....  
and some of those are faster than the others with all cores running....
I actually noticed that some of the miners with cores disabling have a lower error rate than those that keep all cores running too..
again... totally normal....

Even like this so rapidly?

oh WOW, no...sorry....
First, try wiggle the pci cords, then if no workie...proceed to enablecores, and back to the firmware you want...I have best luck with the beta 0.98.1 still....
hope it comes to life for ya..
you should use bertmod to watch until you find the problem, apply fix, then reboot without it....
Good luck...

P.S....You did take the sticker off the bottom of the arctic cooler, right?
How many boards?   figure about 140 per board is what your average should be....

How many modules do you have installed?
What PSU?
Which firmware are you on?
How long have you left it? Mine settles down after a while
Whats the GH/s at the pool?

What I see with mine is a flurry of activity every now and then if I watch cgminer for a long time.

Remember that 5 of those messages are cores being turned back on, and two being turned off.

If you don't want to see them at all then you could try something like firmware 0.96 which doesn't turn the cores on and off.

But the most important thing is what your output averages out to at the pool over 24-48 hours.

I purchased 2 of the recent fire-sale modules for my 4-port Jupiter, but needed to add a couple of pin headers to support all six modules.

I've never really soldered anything before and had no idea what I was doing, but I managed to get everything working! It took a few tries though. I made the assumption that the two blank spaces were simply solder filled holes, but no matter how hot I heated them, I couldn't melt them. I ended up just soldering to the surface.

I'm currently running my existing 4 modules on ports 2-5 so that I can simply attach the new ones onto the side of my open-case Jupiter using ports 1 and 6.

The point of me sharing this is simply to show my excitement and proof that even a noob like me can make this work!

Is there any way the empty ports can be used without soldering and risk voiding the warranty? I thought I had 4 extra ports in my Saturn, but really only have 2 and debating whether or not its worth the risk to add the 3rd. I have some soldering experience, but not on anything this nice.  

Are these controller boards available from KnC in case of a failure? Will the new controller boards be compatible with the current upgrade modules, or vice versa?

[Phoenix1969]

no, the november boards will not be compatible with october controllers....

[Scoobypup]

Still suffering the same Die 0 DC/DC low current issue.

0.99 F/W made no noticeable positive difference.

Someone mentioned shoddy soldering/grounding recently, has that been confirmed at all?

I am pretty sure it has nothing to do with the soldering. My Die 0 DC/DC low board becomes a perfectly working board when I simply unplug the other 3 boards in the system. KnC support suggested I try rearranging the ribbon cables on the controller board to see if the problem follows. I have not tried yet, but will attempt this tonight. Both KnC and Bitcoinorama have confirmed that these dead die issues are almost all not physical hardware issues and more about power distribution and firmware.

Okay, let me help.  Next time you try this first have a soldering iron hot enough; second have solder wick and a small needle nose to hold the solder wick that can get hot; third have some liquid flux, fourth have a soldering iron HOT enough to melt the solder.  For the last I suggest you might try the hobby section of Walmart for a wood etching iron and use the large angle-pointed tip with flats.  These irons are cheap so if flux destroys the tip, throw the whole thing away and get another.  Fifth, get a solder sucker.  Practice on something.  Grab an old mother board, find some solder filled holes, put some liquid flux on the holes and on the solder wick; hold the solder wick about an inch from the end so the needle nose won't sink all the heat; put the solder wick down on the solder filled  holes, press on the solder wick with the flat side of the iron's tip, when you see the wick fill with solder clip off the end of the solder wick and start fresh.  Try the solder sucker on a few old motherboard components.  Practice.

[Phoenix1969]

Now that I've got a steady power feed, I'm going to give 0.99 another try....
Just flashed it....

*edit...   one didn't seem to jump up like the others, even tho bertmod showed all is ok...
rebooted & reflashed it, and it then reacted like the others... jumped right up to speed....
so far, so good...  We'll see what Long term does...

I'm in Michigan, US. I just found received notice that one of my two modules was delivered to my home (I'm at work). The other went from a city about 20 minutes from me all the way back to Pennsylvania and it will be delivered tomorrow. UPS, how does this happen!?

Oh wow.  Be real careful with that.  I could see lifting traces real easily if you put too much force on those.

When I did mine I used a solder sucker and a 25W iron to clear the holes before installing the new pinheaders.  They're now mounted flush with the board just like the factory connectors.

Still, kudos for making it work.  That's the hacker spirit.

Or an SD image ready to run on a Pi...if a Pi can handle running it.

[bronan]

I was thinking the same and will look at the hashrate on the pool
As for the advise on the psu ... some here talk a lot of bs.
I bought a  1200 watt - one rail psu and guess what it turns of the asic boards power
After this fiasco i took my old trusted 1200 watt 6 rail antec and poof running like a charm
power drain according to bertmod internal 676 watt  on the wall i have 832 watt with 0.98.1 showing 696 Gh/s
If i put on the 0.99 firmware it drops to around 650 Gh/s

So 0.99 is much slower

I'm in the same boat, no black connectors attached to my board so I could never add 6 modules to controller board BUT I doubt I'll ever be able to buy anymore module anyway, so the point is moot.

[Biomech]

I don't disagree with anything in this post.  But it seems to me that educating people about pool choices is one thing, and advising miners to arbitrarily leave any pool that exceeds some arbitrary percentage of network hashrate is something completely differeent.

Only if you take Bar as some authority figure (in the logical fallacy sense, not discounting his knowledge).

Otherwise it's a strong opinion from an informed man. It's one I tend to disagree with, because if a pool operator starts pulling shenanigans, given how (possibly rightly) paranoid miners are, it's a matter of SECONDS to pull your rigs to another pool or even to solo mining. I cannot see a pool operator successfully attacking the network for more than a minute or two. I personally see this as somewhere between a bogeyman and a cause for monitoring, not a critical issue to bitcoin. When pools were new and the network small, perhaps. Not so muich now, and not due to the honesty of pool operators (which from my observations has been pretty good).

I would be far more worried about somebody with a lot of money developing their own equipment and hitting the net all at once. Someone with the resources of Bill Gates or Sir Richard Branson could do this easily if they were so inclined. Both men I mentioned are unlikely to, as they both have good reasons not to, but the level of wealth is the point. Given that, I don't think that pool operators are a large threat. I see the above and excessive regulatory horseshit as the more likely threats to the success of bitcoin.

Which brings me to why this is on topic. Those of you wanting the asic manufacturers to hold off have a good point, but in light of the above, for the long term success of bitcoin, they should actually ramp it up somewhat to make such a proposition exceedingly difficult and expensive.
