KnCMiner Jupiter Miner First Impressions

[il_minatore]

Hi guys, I just got my first Jupiter up and running. Before I turned it on, of course I had to open the case, fix the fans (they been flying everywhere in the case). Now I am happily mining at ~522 GH/s. Firmware was already updated to 0.95.
But what is my concern is that 2 14mm Arctic fans are not working. They should be working all time? Or they temperature controlled? What should I do about it?

4 or 8 VRM? Power consumtpion?

thanks

They've been just jammed... I just started them by pushing finger and working fine now.

im having a bit of trouble, if anyone could help me out.
cgminer doesnt seem to want to start when i try to connect to my eligius account. but starts up fine with other pools.
it has worked fine for a week now, but all of a sudden after i tried slushs pool for an hour, cgminer just hangs when i try to connect back to eligius. tried 50btc and thats working too. back at slush again for now.

any ideas, could it be some pool config file that got messed up somehow?
ive tried hard reset, and reinstalling firmware. nothing helps.
im not experienced with linux, but know enough to ssh in with putty and execute screen -r.
all i get when trying to connect to eligius is the cgminer startup screen with " starting cgminer 3.4.0"
and then nothing.

any help would be appreciated.

Whats happening is CGminer is putting http in front of the stratum address this is fixed by either

cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u yourbitcoinaddy -p x

or add pool and use stratum+tcp://stratum.mining.eligius.st:3334

Just stratum.mining.eligius.st:3334 in Web GUI.

an you direct me how to unpack or mount the u-boot rootfs.cpio file? I believe I have found a method, but I'm out during the day so I ask if you have a quick solution to that. Then I will enable to explain A LOT! (Can't wait to get inside, knock! knock!)

did you already solve this problem or do you still need help?

I was away, so, no I didn't mount the image yet.
can you send me a PM with the method you used?

No need to PM i think anbody will benefit from sharing knowledge
assuming you're using a linux version of some sort.

0) download knc firmware (let say kncminer-0.95.bin)
1) tar xfz kncminer-0.95.bin
2) dd if=Angstrom-0.95.u-boot of=Angstrom-0.95.zip  bs=64 skip=1
3) gunzip Angstrom-0.95.zip
4)  cpio -i -F  Angstrom-0.95

if you run 4) as normal user you'll get a bunch of errors due to mknode trying to create a few devices.

2) dd if=Angstrom-0.95.u-boot of=Angstrom-0.95.gz  bs=64 skip=1
3) gunzip Angstrom-0.95.gz

you're lucky man

at the pool mine mint at ~490

since your case is open do you mind to check if your PCB boards have a sticker with a number on top of them?

yes there is a sticker on each board with number 1, what does it mean?

[Bagpipe]

The stickers 1, 2, 3 are from the assembly lines 1, 2, 3...
Yes, there are 3 assembly lines doing this.

[jelin1984]

sticker 1 mean that you have the best chip
that the reason you have that speed

So it is just number or really shows the hash speed of particular chip? Anyone knows for sure... ?

I'm gathering info about that and till now the evidence confirms that the lower the number the higher the quality.

I've measured number of enabled cores to evaluate chip quality.

I've already posted on this forum instructions on how to it, anyway it boils to download bertmod firmware, the file despite the bin extension is a tar.gz file. Untar it. There u'll find among others a file named asic_status.pl, copy it into your mainers (scp), log into ur miner using ssh and execute

perl ./asic_status.pl > statud.html

Copy status.html somewhere and use a browser torender it. It will tell you what u need to know.

E.g. my asic stamped with a #3 have 3 out 4 die full functioning whereas the last one has all cores disabled. The very same asic run a lot cooler (10 Celsius) than the others and consume a lot less energy.

As soon as i will be able to use a proper device with a proper internet  connection i'll post here the link to the step  by step instructions.

edit1: it come to my mind that yesterday on kncminer irc channel (freenode) someone told me his miner has #5 on all boards and in fact is jup hash @340

0.96 is out now

[jelin1984]

check it and let me know asap if core off
make it core on

[sickpig]

check it and let me know asap if core off
make it core on

as soon as possible

anyway pZombie on kncminer irc channel @ freenode said that .96 resurect a completely dead ASIC slot

[DPoS]

I'll give .96 a try on my troubled miner.. I have to keep bringing back VRMs from the dead (once a VRM shows < 1 amp output, the whole die is not used even though bertmod won't show them 'off')

I can get it back but usually turns back off in 6-8 hours of hashing

you mean

the core come on and then come off again?
after some hours?

jelly not the cores but the VRMs, they are  the DC/DC converters you can see in your PCB

what these mean??

I am at work and can't really get on IRC.  What sticker number did he have on his dead board?  Mine was "1" while the rest were "2".
