just now...
Just as a little test... I gently just pressed on the vrm's on the slo sat, and rocked them side to side a tad with the tip of my finger. One of the vrm's gave a little "Click".
within 30 seconds, a couple cores were re-enabled in cgminer... and it has gained about 20 WU's in about 5 minutes, and 2-3 gh/s   Will keep updated...

I think that soy mentioned that a few dozen pages ago. Things get lost in here though Smiley

But I don't understand why if the warm BBB backs up Merc's why it wouldn't back up a Jupiter 4x as much.

I agree... It just doesn't make any sense... I think it's the VRM's getting cooled by playing with the cardboard, etc...  as mentioned earlier..

No, in fact my arrangement probably warms the VRMs a little as I've now got a kind of wind tunnel to the ASIC module and that first passes over the BBB - note the small 120vac 3 watt at the wall fan pushing in from the far left and the two front fans.  So, the ½ fan width cardboard down over the BBB might be better buy I ain't fooling with mine.  ...trying to get on the dreadmill..

not sure but I may have seen a 136GH/s avg earlier.  That first figure cycles up and down.

damn, my mercury is topping out at 119 ghs and that with me doing a lot of reboots. i went back to .95 firmware and so far its the best. havent tried .90 though. the pool shows 103ghs unfortunately tho....i might have to try this .90 like you are using

soy are these temps and current outputs ok?

are they similar to your stats?

how long have you been on .90?

I don't have an answer for your first question, as for the rest it's posted a few pages ago.

Perhaps the warm BBB is changing data and the pool is communicating back the work is wrong.

The increased temps is increased hashing.  The warm BBB is overloaded and backing up I suppose which makes work just sit blocking new work from getting done is a possibility.

I go with (HW*100)/A

HW error % = HW/A+R+HW

where

HW = number of hw errors
A    = number of accepted
R    = number of rejected

with 0.97 I got something like 10-11% after almost 20 hours, whereas before the same miner running with 0.95 I used to have 5-7%

Thanks.  That changes mine from ~4.4% down to ~4.1%.  Although it doesn't agree with BertMod:

Device Hardware%=4.9875
Device Rejected%=4.1048
Pool Rejected%=4.3372
Pool Stale%=0.0000

thanks, that means I am still at 21%, spinning my wheels it feels

Did you try firmware 0.90 then enablecores.bin?  Are you forcing air onto the BBB?  A warmish BBB will drop your hashrate.
SOY, I THINK YOU MIGHT BE A GENIUS....although I am alittle concerned about temps.... here are the numbers for my saturn that was currently underperforming....

new stats

at server
miner_knc   258.17 GH/s   30,875k (99.82%)   52608 / 525k / 2176   noticed immediate change

cgminer stats
KnC 0:                | 305.2G/268.6Gh/s | A:73728 R:3840 HW:5897 WU: 4240.8/m

yay HW ERROR ARE FIXED
BUT

temps went from 40c,45c to now  45c and 52c (alittle worried, should I be?)
watts went from 231w to 381w per bertmod

0.97 also shows a continuous drop of hashrate for me from 500 to 470 (3 hour average eligius).




Actually.. it doesn't seem to be coming back in any previous firmware. Last value was 450 and that's where it stayed. I read compatible reports on KNC's forum. I fear 0.97 might damage bad Jupiters... Careful upgrading yours.


.96 does seem to be better than .97 on good jupiters.   I haven't tried it on a bad jupiter yet..  so far bad jupiters hash better on .94 'overclocked' running bfgminer but the VRMs/chips do have to take a beating..  perhaps heatsinks?

to 'cure' modules, remove the asic_test file and install .96, run enable cores and few times and reboot.   It should do its 1-2 min asic tests and then reboot itself.  you should have more enabled cores again



How do I remove that asic_test file??
+1

Please some help on this.  I can't seem to find the answer.

I'm not sure why you need to remove this file - I would think it would just overwrite it, but if you really want to remove it:

SSH into the machine, then:

# cd /config
# rm asic_test

The '#' is the command line prompt - don't type that.

Well, I read to try it here.  And I read about it on the knc forum.  Seems like someone wants a guinea pig.  Any success with this?  Anyone?

If you are concerned about breaking sth, just rename this file ?
Then you can revert it anytime.

#mv /config/asic_test  /config/asic_test.bak

Is it me or does anyone think KNC not showing up here or in their own forums a bit odd? I mean literally missing in action here through-out this whole process with us. All we have had is very limited support through email and that's it. This really puts a sting on me and would really make me think about ordering anything from them again in the future. Granted, we have had some firmware updates but I don't believe cgminer is even fully %100 compatible with their miners. I bought 2 Saturn's from them. One for me and one for my Dad. My Dad contributed a little money into it and I feel horrible that he may not get his money back, because two months ago I kept telling him KNC will deliver on time for us. I guess I can't blame KNC %100 on that, since the difficulty is rising so fast who would of expecting going from $200/day to less then $25/day in 2 months.

Not sure why I'm even writing this, I guess I'm just venting a little and sorry about that.

A) They have their own and B) what's the point in showing up in this thread? they are responsive to email, if you have a question you can email them.  Unless you have a Day 1/day 2, all they promised you was they would deliver "In October".

Everyone who either had a brain or used the genesis block mining calculator?

They promised Oct 15 and repeated over and over said they were on track for that. It was in huge lettering on their website.

They don't answer on their own fucking forum either. It's all customers helping other customers.
Go back a few posts and see the response given to a hosted customer about his non working hosted rig...a canned response saying we'll get back to you in 2-3 WORKING days. Don't you think that maybe given the fact that they took in tens of thousands (conservatively) for hosting they might consider having some fucker to ring at the data centre or at least someone with decent knowledge on the phone at CS?

Also consider exactly how informed we'd have been if Orama hadn't been here. Not very. Without his inside observation and answering questions we'd be mushrooms. When did you last see an email newsletter? When they were still taking in money? I know one man band companies who deal with customers far better.

and yes, DPos, wouldn't the asic_test get overwritten one you load the new firmware??

So my Jupiter won't break 495GH.. all temps below 45C, I've tried .95 96 961 and on 97 with no luck. Fan mod, case of etc. Any other last ideas?

Have a look into file '/config/asic_test'.

What does it say ?

Good ASIC looks like this:

Code:
ASIC board #4 has 4 DC/DC
Found a KnC miner with 192 cores
KnC ASICs: good cores: 190 from 192
KnC ASICs: good cores after re-test: 192 from 192
Good cores map:

Agree with you, they are great at PR in their own heads, even offering to help other companies to sort out problems when the reality is they are about the worst I've come across for communication. Too busy with that bloody film and promoting themselves to realise that in the end it's OUR experience that makes or breaks them.

The hosting situation is pure robbery, people not having early ordered hosted units running and rigs up and down like a brides nightie ..totally unsupported except for some customer support person who is  clueless. Rigs should never be down for even an hour when hoisted ..that's why people pay the ransom for it. Hardly cheap was it?  

ORSOC are the pros in this, KNC I'll never deal with again, not only because they were late and didn't care...but because they still don't give a shit about the poor buggers still waiting and still aren't communication. One person spending 30 minutes a day on customers...what a difference that would make. We'd know where we were, where they planned on going, we'd be a lot happier. A few lines update every 3 days that is mainly bullshit..that's a joke.

Remember, they are all caught up today with Oct orders. They said so in a news update. Must be true. Wink

more fans.

asic temps are not very important as they are cooled very well with those giant heatsinks.
