KANO...

I am willing to let you play with one of my saturns if that would help, I can provide you with the I.P & password.
Not gonna happen Tongue
I've already got hardware from other companies that I help (and am working on at the moment) so priority of that is way higher.
... and this time of year there is a whole bunch of music work I do also.
Not really interested in hardware, that the company who sells it tells me: thanks for your software - sucked in - bye bye.
... and of course as I have stated before, I don't do remote access support to solve the problems of hardware that I don't have and will not be getting.

You do get that all these firmware/hardware issues are of KFC's own choice right?
Back in July we were told that the testing was off the critical path and delayed until August when they would like our input then.
But then when we asked again at the end of July they ignored us until the "sucked in - bye bye"

Funny, my emails to KFC were very civil, I guess that was my mistake ...

I could not agree more, the least someone can do in return for your help is send you a sample unit.
Especially if they are not paying you anything.


They still might send a mercury.  It is possible their inventory is tight right now.

I'm thinking of getting a refund for November.  I have a feeling I am going to be battling that one.  Sam was such a nice person back in May.  (When I had money of course)  Now they all seem like a bunch of dicks.  They are probably just busy engineers but it sucks seeing how they don't really want to work with people anymore.
They seem to be pretty open to working with people still IMO.
I wouldn't pay too much attention to the troll(s).

(Not to say KnC is The Perfect Company, but they seem to be getting a lot of FUD and exaggerations...)

We shall see.  I stepped up and made an offer to help KNC with an issue that would be very helpful to them and their customers. I assume they are busy making units so we will see if they reply.

looks like 2 saturns may run faster than a single jupiter....   or am I dreaming?

I bought 2 Saturns and just received this week. I'm pulling 272Gh/s avwrage from both on BTC.


for "each" or "both" ? If it is for both, then run enabled cores. It works like magic.

So is there a confirmed "safe" brand of PSU to go with, or just anything but Corsair?

I bought this for my Saturn. It is overkill, but I can run easily run two Saturn's on it with no problem. Did it yesterday when I received my deliveries. Both hashing over 250Gh/s each unit pulling down 300 watts. The power supply fan barely turned on to keep itself cool. I recommend this power supply anytime. I usually buy Seasonic models, but this one had such a good price,  is VERY quiet and very efficient so I went with it.

Did I miss something?  What is wrong with his PSU?  This thread is moving too fast.

KNC is claiming that Corsair (one of the most trusted enthusiast brands) "ramps up current too quickly" and that is why a mining board (powered by Corsair PSU) blew a capacitor.  Of course the fact that a high current switching supply SHOULD operate that way should be ignored.  The obvious explanation is that Corsair doesn't know how to build power supplies.  

I don't believe this at all. I have an electrical meter connected to my power supply so I cam see volts/amps/watts. My Saturn starts off at 20 watts then slowly raises higher and higher until full hashing speeds and max's out around 297 Watts. The power supply isn't going to "push" more or extra amps into by itself...it's the draw of the electronics that I would assume controls that.

This is worrying to me, If I have a problem, I can't strip down and pull meters out to check things at component level, All I can do is plug it in and check the connectors are in  Grin If mine arrives dead/underperforming, I don't know what to do.

Jesus man, I've been reading 12 pages just about talking about power supplies! WTF?

Just buy this one: http://www.corsair.com/us/power-supply-units/rm-series-power-supply-units/rm-series-rm850-80-plus-gold-certified-power-supply.html

You can use it for a Saturn, 2 Saturn's or one Jupiter. When I use it with my 2 Saturn's it pulls down exactly 600 watts, which leaves a little room to spare. People buying these 1000 Watt monsters. Crazy.

One of my miners hashes to a max for a like 4+ hours straight; then, everything fails. it goes to like infinitety hardware errors and 0 hashrate. What could be wrong and how could I fix this?

you're probably using pre-94 FW and one of your dies/VRMs is a bit flaky

What are these VRM's you guys talking about? Are those the silver metal boxes on top of the modules with a little white sticker on them? Do these regulate the power? If so, then the firmware has to be written just right to communicate with them.

The power supply isn't going to "push" more or extra amps into by itself...it's the draw of the electronics that I would assume controls that.

It was explained elsewhere with more details. That's not normal power on phase, but a specific case when, due to temporary overloading, Corsair PSU shuts down itself. When it is turned on again during 30 seconds after the shutdown, it can then put full voltage (or rather more than that because of inductancy) immediately, what causes great impulse of current to capacitors and in effect can blow some. (Of course this explanation is still simplified.)
If you can simulate such a case, fell free to use meters, but an oscilloscope with memory would be much proper tool.

DeathAndTaxes, your "obvious explanation" is incongruous. Of course they know how to build, but everyone can make a mistake.
Don't judge other engineers upon oversimplified/twisted information passed through a line of people claiming they don't know electronics.

You're free to do what you like. By the way, though, cgminer is my project. Kano is a value contributor but not the maintainer, and while I have complete control over what code to include, I have zero ability to control what he says or does on the forum. Note that in the future, I will be working on the kfc driver code.

Yes, silver metal boxes.
VRM = Voltage Regulator Module or DC/DC converter.
And yes, the firmware communicates with them.

can someone explain exactly what the "hard reset" does...   does the firmware stay, or revert to...?

That "hard reset" never worked for me. Press the button 5 times, wait 5 seconds, then presss again 5 times. Nothing. Nada. I even have a constant ping on the IP address and that never even goes out. What's up with that hard reset? I truly would think a total power off is the trick.

Both CKolivas (CG) and Luke Jr (BFG) have their own dev boxes, they were sent at the same time they were emailed the source code at the beginning of last week.

Make my day! Say thanks if you found me helpful Smiley BTC Address --->
