I have 200 amp service and don't even have 220, I installed it myself under the direction of professional Electrical contractors, and the county inspector. I believe him.

I don't believe you.

Quote
Volts x amps = watts, Period. You can re-arrange that any way you like.
Watts / amps = Volts
Watts / Volts = amps
That's only for DC and instantaneous AC power.  The proper way to calculate average AC Power is via

Pavg=V*I*cos(x)     cos(x) is the P.F.

PS: "Volts / watts = amps" is wrong.

Quote
But if you really want to save $ on electric, you MUST get a Power factor correction Capacitor
it will save you 20-25% off the top if you are seriously mining
(The scam is electric companies actually charge by the volt-amp, and not by Kilowatt-hours) This corrects that.
http://www.eaton.com/Eaton/ProductsServices/Electrical/ProductsandServices/PowerQualityandMonitoring/PowerFactorCorrection/index.htm
You only need P.F. correction if you live in a area with shitty service.

That would be 100 amp service at 240V. You have two 120V phases coming into your house each at 100A. Five Neptunes is a lot; but, you make sure your running 3 on one phase and two on the other.

100A x 240V = 24000W

or

100A x 120V + 100A x120V = 24000W

Same power...two phases.

^^^^This. With a modest ~2kw in equipment right now, my house is already above 10kw/h part of the day due to 100oF outside.
I started thinking about solar panels, but they are too darn expensive, like 15K for 5kw worth.
In Texas mining looks more and more like a winter "sport".

Sorry for the off topic but when I restarted my October Saturn it just keeps rebooting after 5s being responsive to Ping's ... at the same time it resets the blue light flashes very quickly.

I found that If disconnect one of the asic board from the board the miner runs well with the remaining one. ... I already tried to connect the "bad" asic to other connectors on the controller board but the same thing happens. ...

Is there any logs that I could look to see what is going on?
Does anyone saw this behavior before? The miner was running for ~25 days 24x7 without any issue but now this happened......
Does it mean the board died?

thx!

I have 6 ports on the controller board and it is running firmware 1.01
Somehow, after rebooting the controller many times and factory reset the settings with the asics .. and the restoring one asic board per time is now working .... no idea what happened or what was the problem...

thx!

I missed the part including the begging. I can't take 100mp+ chip photos without a unit - I'm not magic.

I think you should demote their manufacturer trustworthiness on account they didn't send you one. D-

No joking, they should be at D- anyway.

They only went from A to B+ after the datorhall was revealed! What a joke demotion that was!

If dogie's guide is supposed to be some measure of trustworthiness, then surely doing something that fucks all your customers - past and present - to line their own pockets is about the biggest mark of manufacturer untrustworthiness there is? They should have been right down to C- or D immediately.

With frankenjup and withholding neptune refunds for months, knc should be right down at D- or lower now.

I have to agree with this. The lies they told and then turning the customer into the competition. Shameless and pityful.

Mmmm .... Lurked on this one for a while ... and have respect for Dogie with his excellent teardowns ... but KNC surely lost all trust some time ago?

If not ... why not?

Anyway, if it's too dull here, head over to the knc forum.

It's HOTTING up (we love those overheating jokes!) for reports of hot PCI cables, dead controllers and DOA units  Cheesy


Edit. Just going to add this statement from Colonel Kurt from today, so we (well, me anyway Grin ) can laugh about it later:

Quote
Today, 04:58 PM
The miners are tested as working perfectly before shipping. As soon as this this miner is created, the QA process begins, then the miner is shipped.

The QA process is an important and relatively fast part of the procedure. I am pretty sure that customers who are to receive these miners are grateful for this extra step.

Did I suggest earlier today that these rigs were probably not being burned-in? I think I did.

As someone who isn't an obvious shill or troll,  I also agree.  The 2-1 thing and extra neptune being exclusive was outright deceptive.
