There are various text editor, i prefer nano or pico but they usually not installed. So you can use vi which is always installed. Google vi for more information.

I don't think this was ever proven.  I think it was FUD spread from those who did not like LKETC.  (They made a few enemy's when they did not release ssh password on newer firmware).

But again no proof this has ever happened fro lketc to my knowledge.

definitely lketc, have software in their sd cards to steal hashes

so bad..

You will need to use a text editor through SSH.  I do not remember which one it has on system.  Type "nano" or try "gedit" and see if they bring up options for a txt editor.  I would think it has nano.

how can i use that? i dont have experience..
could you explain please?

Have you tried a txt editor when using ssh? Gedit, etc.

winscp ss: http://prntscr.com/77r1fu -- when i trying to open /usr directory, i have no access to it

putty ss: http://prntscr.com/77r22v

when i put cd /usr/boot - path not find
but when i seperate it, guess what? it works cd /usr - cd/boot - after it "ls"

how can i download or change premissions?
 im tired of this.

At the moment I don't have access to a dragon.  I believe cgminer folder MIGHT have it.  And if not I think there was a settings file or something that showed pools and lots of info in one of the folders having to deal with the GUI.   But I cannot remember the name it's been a LONG time since i sshed into one.

My dragon 1.5T I have not had to touch for over a month.  

Ok,

i will check. thanks.

whats wrong with first paragraf? what did i type?
----



where is located file with Ghz info? Can you give me exactly lcoation of it? In this thread https://bitcointalksearch.org/topic/dragon-miner-overclocking-552946 is only overclock installation, there is not path to the directory?!?

Re-read what you said:


That was what I was answering to

I posted a link to thread on overclock information.  With that and the SSH access you have you should be able to log in, check freq.    Don't do the overclock just look at freq.

I already saw that topic... thats why i am asking for difference between those chips.

can explain me please?

Look over here - https://bitcointalksearch.org/topic/dragon-miner-overclocking-552946

And be careful the 1T's with 4 blades are really pushed very very hard from start.  So I don't suggest overclocking them.

I have do to some pics and post here to see.

But, anyway is there any method to see is it overclocked or not? Im sure, that must be...

Do you have the 4 blade version?  By default it is cranked up on frequency.   It's not really advised to go higher.

What model/brand psu is in your miner? 

Where did you buy it from?  A lot of hosted ones were ran very hot a defective blade would not be surprising.

hi,
thanks for replay.

firstly, i want to ask you this.
How can I know which chip my Asic using, I never checked this.

Secondly, I have root access now. How can i check is my asic overclocked or not?

Thirdly, i changed some cables in miner, and i got same results in hashing for all boards(i think so).

For sure i will pay shipping costs. Just write me pm costs you paid for and tracking number.

thanks,

Sorry for delay was 3am my time just wanted to get that out before hitting the bed.  It looks like there is failing chips on the fourth board.  Most likely like nolist3d said it's had a long life.  After about a year of running at the bleeding edge of what those chips can do they start to fail one by one.   I see a lot of hw error on that one board if you could down clock it it may help but I think you are getting the most out of it you can.   I have also grid miner a1 and those use same exact boards only they put 5 in and run them at 800 MHz.  They all run about 205-210 ghs each.  Totaling about 1.1 ths. The dragon they elected to go with 4 and overclock them to 1000 MHz.  I've got 15 dragon miners and some with burnt psu. If you would like to pay for shipping only I would be more than happy to send you a good board.  I will verify it is working correctly before I send it.  If you are interested I'll pull one out later today and get it sent by tomorrow.  As long as your ok with swapping them out.  I'm sure I can get pics if it's necessary on how to get it removed and installed.  I haven't had a dragon open for quite some time so I need to look at one and refresh my memory.   I'm sure it's not that bad to replace.  Anyway let me know what ya think if I can help I'll be happy to do so. 

Best regards

You might check and make sure power supply is adequate. If not enough power could cause loss in hash.

Also with it being a Dragon 1T it's had a LONG life so far it's possible it's been damaged do to running it hard.  You could lose chips, etc if ran to hot.

For ssh, you don't need linux pc, what d57heinz mean is linux command knowledge.
You can use putty if under windows.

here is real time monitoring: http://prntscr.com/779nfo

look up at red arrow, i see lower price then other chips.

i'll send picture of machine inside, and how is it connected..

btw. i have a little bit linux experience.. but if this one isn't overclocked.. tell me how can i access to it and overclock it. thanks

/edit

i see. firstly, need linux machine - my question is. can i do that over virtual linux machine?

Also if you have Linux experience you might be able to ssh and overclock. But if my memory serves me right. They already have those 4 boards overclocked to 1000mhz.  The ssh login I used was login=pi. Pass= innosillicon

Can you post a pic of real-time monitoring. When I ran those machines I would get around 1020 ghs tops. Maybe you have a couple bad chips.  In my experience if you are running them on 110v then the psu installed is at its limit.  Could try taking an additional psu and pull one of the pcie connectors and put secondary on that board.  Turn the secondary on first then the main psu for dragon miner.  

If you get same results most likely that is all you can ever get.

if the difference in hashrate is only 10%, and you are seeing it in the pool, then it is normal, they usually dysplay an estimated only

also your local say average 950, seems good enough for me, 50giga difference could be for anything

miner is bought from but their support is very,very bad. They not responding.

I have next problem.
this is local host: http://prntscr.com/779170
and this is pool btcguild: http://prntscr.com/7791dc


I have never get over 900gh/s on any pool. Is there any fix for this? Firmware upgrade or something similar.

thanks
