Yikes... you know what your electricity bill is gonna look like, right?


For those running GPU rigs in the past is KNC miner not a big difference  Tongue

I'm in Minnesota they say the rate kwh is 8.6c per kwh but when you add the taxes and fees etc it comes out to .15/kwh..now the elec company said I could get commercial rates in the house....they do a free audit..check the equip for watts x24/7 should not be a problem...they say the commercial fees are more but they figure I could save 3c of more per kwh..so what the heck will see how it goes....

but again ....take your whole bill and divide by your monthly kwh use....

I'll let folks on here know if/when/or how much..if any  I save by this energy audit for a commercial rate


so pretty much a no brainer.. at least to check it out

Why would his PSU "die" when yours wouldn't? I have a PSU in every company, and that qualifies me as the expert. You cannot just say something will die maybe unless you have proof. Again, I have every PSU ever made.

DID ANYONE RECEIVE KNC UNITS TODAY? AND IF SO, ORDER #/PAY DATE PLEASE??

trying to gauge more or less where knc is at as far as shipping queue/order #/pay date?? thanks.

Yes, sir Smiley
Proud day2 owner reports: order received this morning and is meanwhile up&running.
The whole scene from UPS ringing the bell until now still feels like a dream...hopefully it is real!  Wink

order number was <300, paydate early june,
based on pre-preorder from may

0.91 firmware, flashed to 0.93
cgminer restarts quite a lot, but hashrate is 500+ avg

Packet damaged from the outside, inside is fine.
One fan was loose, clipping it back on was easy (make sure you have a torx screw-driver present to be able to open the miner's case!!!)

btw:
had trouble with the config - wanted to add to /config/cgminer.conf another pool, but after restart cgminer complaint about no pool;
double-checked the JSON everything was fine.
So I removed the config completely and restarted cgminer. Then connected to it via ssh/screen and put in another pool through cgminer directly and wrote it to file on disk.
I hope it's still present after a reboot, not tested yet.

Hello,

I spoke with KnC on the phone again (!) about the hosting.
All DAY1 customers with hosting should have their miner up and running in the hosting center by today (Tuesday).
They will receive an e-mail with the access informations.

I assume this will be just the web-interface. So I already sent them an e-mail yesterday requesting 2 external
pools to be configured (which can only be done via ssh access inside of cgminer).
I don't believe this will be done without a further call, but let's hope for the best.

I cannot enter in the "mining" tab from the webui in one of my miners after I manually set up a failover pool in cgminer - everything worked fine until I added a new pool, removed the previous one, and added a third - now when I click on the "mining" tab on the webui I get a blank, white page.

Obvious SSHing the box and configuring cgminer directly still works.

This happened only in ONE miner, the rest are working fine despite of adding a failover pool - nevertheless, for those miners I just added a new pool and enabled failover, on the contrary on the "faulty" miner I did and undid a few changes in the "pool management" in cgminer.

Anyone with the same problem?

I'd expect they have better things to do than adding for certain customers additional pools, etc now.
They said, in the beginning there will be the KnC-pool available, only as far as I can remember.
As soon as the management interface is up&running you can do what ever you want.
I'd hope they will not modify the config file via ssh for each and every hosting customer asking for it as it would delay startup even further.

---
Update regarding my received day2 order.

I reverted firmware version back to 0.91+rebootfix:
runs way more stable now - not a single reboot in the last minutes
(valid) hashrate is still around 500+ 20% lower in avg due to a lot of hw errors - the actual one is still >500
~/.ssh/authorized_keys not present after firmware downgrade
custom password still present
modified cgminer.config present

Yes, after adding a backup pool within ssh/cgminer, I get an empty (?) page from the web interface on the mining tab.
It's pretty OK for me, as I don't need the web interface for configuring mining pools.

Problem report sent to KnC support:

Hello,

my Saturn miner is running with about 7.5% HW errors (0.93). It looks like this is normal / known by KnC.

But my cgminer process also terminates itself from 2x per hour up every 3h. I did not observe any uptime
of cgminer much greater than 3h.

I observed (by pure chance) such a restart life:
Everything did look normal. A new status update in the bottom of cgminer every few seconds.
Suddenly there did show up error messages like

KnC: accepted by FPGA X works, but only Y submitted (where Y=0 or 1 only I think). X was always < 10.

I did not manage to make a screendump fast enough.
Those messages did show up at a rate of 10-20 (?) per second. SO really fast. After a few seconds the
screen session did terminate and the cgminer process was restarted.

maybe unrelated question, but how did you manage to restart cgminer in case you hit Ctrl+C on cgminer screen? the only way  I found is to click "Apply" button on miner tab

I can fully understand if KnC can't configure backup pools before they have solved all the other problems with
the hosting, BUT:

- I have not heard anything about the KnC pool yet. After all the current problems (like webinterface having no option
  for a backup pool) I do not have trust in a KnC pool at the moment.
- From another call with KnC I still assume that no one will get ssh access to the hosted miner. In combination with the
  webinterface not offering the config of a backup pool, this is something that KnC must do manually. Sorry!
  The hosting is overpriced for a normal hosting and I assume one reason is that KnC must do additional tasks normally
  not covered in a normal hosting:
  Doing software / firmware updates.
  Configuration of "normal" mining features via SSH as long as the customer available web interface does not allow this.
  Replacing units that caught fire / did explode  Angry  Sorry, I could not resist!

In response to my asking about SSH and back-up pools (5-day old reply):

Quote
We understand your point of view and appreciate you shared your ideas with us.

Due to security reasons, the ssh remote access is only available for shipped devices. For hosted devices we offer web portal where you will be able to configure some changes.

At this time there is no option to set back-up pools but we might consider it in the new versions of web portal. However, there is a possibility to switch the pools manually.

update

jupiter received with v.0.91, upgraded to 0.93 => lots of cgminer restarts
downgrade to v0.91+rebootfix => runs stable, more hw errors, 20% lower effective hashrate
upgrade to 0.92+rebootfix => runs stable, 30% hw errors , 500-/+ effective hashrate avg

btw: after flashing downgrade it was not responding after reboot, had to power it off and on again, then everything was fine again

It`s a shame for KNC.... people get their unit a week earlier than others will receive for same confirmed production day (day 2 should be shipping). It seems "one KNC-day" is nearly a week in rest of the world.

well why wont you go over there and make miners for them and see how long it takes you. Thies things are not all automated on the putting together process. It takes time to make/pack them. Damn hold your horses.  Cool

Well, at least it's not "two weeks"(tm) equalling 2 years.  Wink
