Ah, I assumed the 4th pin was for speed feedback so as to allow a notification if the fan failed.

Wow!  20nm AND early 2014!

That MUST be the "incoming news" announcement from 'orama.

KnC:   core 3-0 was disabled due to 3 HW errors in a row
         core 3-82
         core 3-162
         core 3-52
         core 3-87
         core 3-50
         core 3-179
         core 3-177
         core 3-45
         core 3-27
         core 3-188
         core 3-35
         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.

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.

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

Aaaah. What dows coming soon mean? How soon is soon???

Hmmmm, BTC Guild and GHash.IO 28% Hashrate respectively.

this is big

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 ?

Some good news ;p

Day is almost over, what ya got?

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

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.

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 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:

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

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:


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.

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
