Swedish ASIC miner company kncminer.com

I've just created a kncminer branch on my github and have imported their most current code and built my first binary for this. It is not a full firmware and the only thing users may note is the hashrate won't lie with this one, as it won't count hardware errors as hashrate. Also my hardware error count is significantly lower with this on the Saturn dev machine I was sent.

Here's a direct link to the binary:
http://ck.kolivas.org/apps/cgminer/kncminer/cgminer

You'll have to ssh into the kncminer and copy and use that file directly. Hopefully the libraries all match between my dev environment and the default kncminer operating system which means the binary should just work if you run it like on any other OS.

Sorry, but what would be the benefit on doing this? I'm not trying to be an ass, I really don't know.

So I was one of the lucky ones that got my Jupiter which came with 0.95 and flashed it to 0.96 and got it hashing at 555 Gh/s on the miner and 555 Gh/s on the pool (Slush)

0.97 dropped my performance down to 525 Gh/s on the miner and sub 510 average on the pool. I left it a few days to get up to speed but it never did.

0.98 showed no better, if anything out was worse with cgminer disabling and enabling cores all the time. So in desperation I flashed back to 0.96 and everything is back to normal speed.

Weird.

Oh and my miner still shows 1.1.2000 after reboots and never change to the correct date.

Otherwise everything is good

[timmmers]

wtf ?!
they send you untested broken crap for several $k and you have to pay for sending it back ?!

does this even comply with laws concerning B2B ?

+111111111111111

My thoughts exactly. Why the shit do I need to pay for shipping on a dead unit they sent me?

It's not right but would you prefer to wait for them to get round to sorting it out ? Tomorrow means something entirely different in Sweden apparently.

A bit like manana does in Spain.

Don't worry, there is no need now with 0.98 firmware from kncminer having most of the changes from that binary included now.

Thank you KnC for the 0.98 firmware!

Edit: Also thank you ckolivas for your work! Tip incoming!

You're welcome, and thanks!

With 0.98 installed, everytime I restart CGMiner via the web interface, and then quickly start a screen session so I can see the startup, I see the warning "Error in configuration file, partially loaded.".  If I start cgminer by hand with '-T -D', I see this error:

Code:

[2013-10-29 23:20:43] Invalid config option --api-network: Invalid value

Looking at the config file saved by the KnC WebUI, I see this line:

"api-network": false

as the last line in the file, before the closing brace.  Looks ok to me...

Any one else seeing this?

It doesn't matter if remote management is enabled or not, it still causes the error.  It still starts and runs, so it's not a show-stopper, but I don't understand the error.

confirmed slight performance increase at the pool for 0.98

[ASIC-K]

3 hour steady at 140. slowlllllly increasing

When I first got my Saturn I removed the heatsinks, cleaned off whatever thermal grease that was there ( it was very thin stuff ) and put my own Artic Silver high density stuff on. Since then no matter if the temps are cool or hot I've always hashed on average 280-285. Top off, top on, fans on or on...always the same. Maybe the thermal grease or whatever they used was just inferior low quality stuff? After the grease dries up a little it should thicken up...when I received my miner the grease coming out on the sides was still almost wet. Maybe if you can't get your miner to hash up no matter what you do, try to clean off that crappy thermal grease that's there and re-do it yourself. AND REMEMBER, all you need is just a little eraser sized grease and not to over tighten. And I'll still not break even probably.

Did they do worse before you changed the thermal paste? I doubt that it's much of a problem, it seems like most people are getting  280 saturn /560 jupiter without doing that. Some people are having issues, but that's probably not related to heat.

I never trusted the grease that was on there to begin with, so I only powered up for about 20 minutes to make sure everything worked then changed the grease over to what I wanted. It could have been the same, but my Dad who has a Saturn also has great running speeds also and I changed his thermal grease as well. It can't hurt I guess. The stuff that I saw there just didn't look right. Very bright silver stuff that was almost wet. That's what made me change it to begin with.

Also, if you hate editing files while in SSH you can always do the lazy mans way. Download WinSCP and log into your miner that way. It's all GUI for those of us that hate text based stuff. You'll get a good feel of the file hierachy and it is easier to move around, at least in my opinion it is. I'll just download a file, edit it locally and then upload it. I hate VI. Also of course, you can download all  your files and make a nice backup locally.

You guys are gonna think I'm totally nuts... remember how I removed the ASIC fans??
Well, my basement is so cold that I'm now experimenting with freezer bags covering
most of the heatsinks.  lol  Temps went up about 5C and confirming more hash and WU.
Power draw is about 343W. Temps are in the mid-40Cs. I'm thinking maybe the ASICs
need to be warm, but the rest of the components should be kept cool. I put rubber bands
towards the top to keep them in a steady position after the pic. And check-out my peak
number!!! FM 9.8 and enablecores. I have not done a restart after initially putting the
bags on less than they are now.

I think there is nothing wrong with the thermal paste used on the knc asics, but yes they have used plenty which actually is not really needed but its pretty the same quality as arctic silver
This asics actually do like it warm, this does not mean you should remove the cooling. But when i put in 2 tornado fans which gave a drop from 62 c to 28 c on the asic cores it made them slow down.
The hash speed ended up being on avg 210 GH at that moment.
Before anyone asks NO the psu is not a weak one its a 1200 watt Antec so for this simple saturn even a bit overpowered with its 6 x 30 amp rails.

Now when i removed the tornado fans the hash went back up to 265 Gh on avg.

[demonmaestro]

DHL is odd. It got to the states fast. Now its came to a craw.. 

[Biffa]

Hmm slush's seems to be suffering from a DDOS

[elasticband]

my knc is doing 800GH 620w at wall

[elasticband]

[ASIC-K]

actually, its not. its doing 550

[elasticband]

Yes I already knew this.

not sure how i feel about .98

75w more at the wall, and depressing specs 800/550..... back to .95 i go


edit: on second thought my HW rate has dropped from 10 down to 2% and my hashrate is staying pretty stable at 550gh/s

Wow!  In my opinion you're just asking begging for trouble.   

Do we even know for sure that the temperature sensor is located in the chip itself or somewhere adjacent?  You could possibly cook your chips and not even know it was imminent by checking your status page temps.

[edgar]

elasticband - wtf?!


xyzzy099 - are you able to amend

 "api-network": false

to

"api-network": true         ?
