The error seems to have been thrown by /etc/init.d/cgminer.sh
I can't seem to reproduce it right now.  Instead I am getting "-sh: etc/init.d/cgminer: not found"  however "less /etc/init.d/cgminer.sh" gives:

It seems you've missed the leading slash before etc, no?

just execute the command:

Code:

/etc/init.d/cgminer.sh restart 

It seems you've missed the leading slash before etc, YES?  Stupid error

bless u biffa. i KNOW when im being a dick, and its usually intentional...

i agree phoenix HAS made some great contributions, but hes also made some absolutely shit ones and seems to not know the difference nor appreciate constructive criticism.

anyway, now hes given it a rest the thread can continue to provide much needed & appreciated support.

thx again and ill try & tone it down a touch.

i considered removing the blue extensions but so far im leaving it at 529Gh - i'll maybe have another fiddle when he Nov shipment arrives.

Dont wanna make it worse until i have some backup hashing power

strange.

since there're a lot of things going on when you issue a cgminer.sh start and a lot of those are related with the initialization of the asic boards I'm afraid that there's something wrong going on in this phase.
this are all the tasks performed:

Code:

root@lucas:~# fgrep \# /etc/init.d/cgminer.sh 
#!/bin/sh
        # Stop SPI poller
        # CLear faults in megadlynx's
                        # Re-enable PLL
                        # re-enable all cores
                        # Disable PLL
                        # disable all cores
        # Disable direct SPI
        # Enable SPI poller

all of them involved some sort of i2cset command executions.

If I were you I would join #kncminer channel on freenode and try to ask hno (an OrSoC eng) if he have an idea of what's going on.

i am testing right now cgminer-tune with my jupiter that has got some problems at the beginning and is mining at 520GH with 3.8.1. i can report that the jupiter is hashing now at 480GH . and i am not sure but it takes some time till the working diff has changed usually i think it got changed faster. i am mining on eligius btw.

i will update you in 2-3h.

edit:
after one hour it is working at 511GH/s

I have been trying to figure out why two of my boards (one new, one old) from upgrading my Saturn now are reporting dead dies 0-3 with no output wattage for the two boards. Running enablecores hasn't changed anything, and firmware 0.98.1 didnt work and neither did the older firmwares. They both don't hash on any port now and I'm running a XFX Black Edition 1050W with a Seasonic 1250W Gold coming in later today. My bertmod output with the two dead boards are below:

Heads-up for tomo BTW - incoming...

is this kind of post considered useful?


why not be a tad less 'cryptic' and you(r inbox) might not get abused so much...


Also want to add, my ambient temps are 30C - 86F.

 so statements regarding VRMs needing heating and/or not liking cooling is NOT a fact covering ALL rigs/VRMs and even when they are hot(ter) they dont ALL fall back into line....

im sure ive mentioned this...

As for 'wiggling' the heatsink aka 'cooling tower' - i think ill give that a miss.

i personally dont want to hear 'warranty' is void due to negligence/abuse/possibly insane advice (though it might just work)

Nobody said the temp issue covered "All rigs", and you still don't get what sharing info is about helping others in need, who ARE having problems.... and if you cared to read just a few posts more, before bashing O'rama, you would have seen that he spelled it out for those who can't "Read between the lines", but you still even missed it.
What is your problem? Someone piss in your Cornflakes?
I also stated clocking the heat-sink was a desperation move on my part, and that the temp thing was NOT a recommendation.
It was a question!!!
But.. it has helped others.
There are two options when you have a board that isn't performing up to spec as I see it..... RMA it, or try to get it going yourself.
Which one you try, is up to the owner...
I'm an "Open book" in here, which is something I'm not used to...  but if I can help someone, by golly..I'll do it....and share every conventional AND unconventional solutions I find. It is then up to you as the fellow KNC miner owner to make a decision based on how you feel about it.
You would rather see everyone with a simple glitch on board do an RMA when they could possibly be fixed so simply?
Not me... 

The temp issue is confusing.  ASICs will have increased errors as heat increases since impurities will cause triggering of gates at random causing illogical conditions which themselves can cause more heat.  If VRMs are running better hot than cool then I would think something is wrong, e.g. some open that closes with expansion due to heat, otherwise I don't see how heat can improve operation.

I am not sure this is the right place for this but this seems to be a catch all thread so here goes.

I have 2 late October Jupiters.  One I was able to get to 550 with all cores running under 98.1 beta.  The other has 2 cores on one board that will not work until 73C or 74C and as soon as they start the whole board shuts down (I assume thermal shutdown) so it only works at around 480.

I was living with that (not economically feasible to give up 480 hashes for 2 weeks to rma the thing just to maybe get another 60 or so).

Now the problem.  I shut the full speed unit down for a few minutes to change locations and when I restarted it cgminer fails to start.  The bone boots and I can tty into it.  I can try to manually start cgminer and I get a "cgminer failed to start: Write Error".

I tried changing firmware.  Cgminer will run on 98 but not on anything after and on 98 I have all die 0s dead.

Anyone have any clues?

Put a voltmeter on your power supplys and check you have ~5v and ~12v.  Also, I found my 4 pin molex could have been a little loose on the pins and closed the "tubes" a bit to fit more snugly on the board mounted 4 pin molex pins.

[soy]

Ok the Noob , (thats me) got it working....

So i upgraded the modules and my saturn is hashing at a jupiter speed ...only one prob ...the front fans on casing have stopped working ...any idea why and solution ?

12v to the 4 pin molex is missing or needs a common ground.

Some good news ;p

http://forum.kncminer.com/forum/off-topic/miners-cafe/18830-good-news

[AFox]

I just saw that the controller as two 4 pin fan connectors for the box fans.
But the box fans have only 3 pin connectors.

On a computer motherboard, a 4 pin connector allows the computer to control the fan speed to reach a targeted temperature.
Could it be the same on a Jupiter/Saturn ?
If yes, what is the target temperature ?

I would'nt be a competitor of KNC right now....
Don't wanna think also how many people wasted money in vanishing pre-orders.

KnC:   core 3-0 was disabled due to 3 HW errors in a row

         core 3-77
         core 3-40
         core 3-58

This is with cgminer-3.8.2 tuned.  It makes no difference between stable and tuned.
        
My die 3 is the problem one.

I get an occasional errors from die 4 and 0 with one bad thread

KnC:  core 4-0 was disabled due to 3 HW errors in a row
KnC:  core 4-130 was disabled due to 3 HW errors in a row
KnC:  core 4-118 was disabled due to 3 HW errors in a row
KnC:  core 4-64 was disabled due to 3 HW errors in a row
KnC:  core 4-113 was disabled due to 3 HW errors in a row
KnC:  core 0-33 was disabled due to 3 HW errors in a row

But my die 3 is the troublemaker.

[/quote]

felix is it 15 bad cores or 5?

You know that with the tuning cgminer it turns cores on and off to try and find a stable medium.

What are your HW error %'s?

I've given up on the firmwares that pump the voltage up (>0.97) and tune the cores, I'm sticking with 0.96 and the non tuning 3.8.2 cgminer and my HW errors are down from 4.5% to 1.3% and dropping.
