Say for equal GHashes,

  Gen1 price is 200 BTC
  Gen2 price is 100 BTC

Basically KNC, and every asic manufacturer should,

1. Ship all gen1 asics
2. Make sure all gen1 asics shipped, started hashing, and last-shipped gen1 asic mined the price difference worth of BTC (200 - 100 = 100 BTC)
3. Start shiping gen2 asics

Right?? Or, whatever. Sad

Hi,

As many of you are already aware, there have been a lot of issues with firmware for the KnC series miners, attempts to replace this code with familiar tried and tested systems fails because
the system right now works in flash, which is why you loose it on reboot.

So my plan is to source a beaglebone and develop a microsd image with a more common OS like Debian or Ubuntu with BFGminer on that i can release to everyone thus surviving reboots.
If you like the idea donate here:   1Nm8mRuuCYQqDwY8HhNGPsAQ1KKE3ykQ7o

This will be a plug a play type setup with minimal config required.

I.e copy the image.iso to a microsd  plug the microsd into your miner and reboot..

Smile Smiley

I've started a thread here https://bitcointalk.org/index.php?topic=321930.0
And here http://forum.kncminer.com/blogs/the-big-countdown/13322-custom-os-image-for-knc-miners

100BTc=20k$  Cheesy let my see, diff will be 1000mil min 2Thas not enough 20Thas to have a ROI unit with a lot consumption,  literally there will be not roi units, but folks somehow don't care

Your right madsusie no miner is going to make roi unless a person is not paying for his electra bills then that person can make profit,
unless the value of btc becomes at a massive value to make up the difficulty.

Which i believe will not happen anytime soon.

However since i do have to pay 0.32 Kw/h on electra and pay massive taxes over anything i buy in my country.

Its not longer possible to make mining worth the effort. Colocating gives other problems in general makes things worse.
The problem with hosting is the hands when it goes wrong, and you need a person which has knowledge on these machines.

Second the prices which the asic companies ask for their $8 value chips is insane.
Do not come with bs about they cost more because they don't,  their cheap and since the foundries have a new market they probably dropped even lower in price.

Asics are made in massive numbers each day since they are used in many products todo their respected tasks.
They are simple chips compared to cpu/gpu and not programmable like fpga so after this task you can not use asics at any other task which they are made for. They are instant useless so selling you expenssive bitcoin miner becomes a pain when its no longer able to make some coins for you.

They told me they planned to have
A month in between shipping, and I believe they will hold up to that, other wise they would piss off allot of customers, and anyone smart that paid with a credit card could get a refund if they wanted, and would lose allot of customers if they plan on having a gen 2, though a gen 2 would only be worth while if they got much better watt  / gig performance

Yeah, their shipping times have always been as they say, and they hate to piss customers off...or even talk to us come to that.

I'd bet that Nov orders are quite small given the difficulty we all knew was going to be this bad, and if power usage being lower than current rigs is such a big thing. Gen 2 will have to have a much better dollar / gig performance, who cares about power consumption of a few quid when you're talking about rigs that should be making hundreds a week? Power use should be about those last few months just above break even not massive thing. People see a 2 week delay as OK despite that meaning missing so much income, then witter on about the cost of a couple of light bulbs in power consumption? WTF?

I beg to differ. 1 Jupiter costs about 135€ in power per month. That is at present pretty much 1 btc. If next gen miners can lessen that by 30% that would mean a LOT more money in the long run. Of course, if you are in a country where you don't have to pay more than 13 cents per kwh you obviously don't have to fret over power consumption...

A jupiter would cover that 135 in 2 days sitting instead of waiting to be shipped at KNC. A next gen rig would need to be at least the same value as a jupiter right now to be even considered. Power is the last thing that needs to be improved, and any improvements will be pitiful anyway. IF the people who only just got their jupiters had been offered the choice of one on the 15th as promised but 1kw ...or what they got...14 days of no mining and a diff increase...which would they take? 2 weeks mining at 500GH or save 70 euros? Which is more important?

1BTC is a lot more than 135 Euro right now too.

Hey, don't preach to the choir. My UPS delivery from KNC directly is missing... so, 2 weeks late vs now 4 weeks with me.... I am lucky that my first units got here on the 16th late afternoon, also UPS, delivered to my neighbours babysitter (while I was at home...). But  that was not the unit from KNC directly but from a forumbuy. So yeah, delay sucks, but when you get your units what is more important is power consumption.

Found my Jupiter hashing at 140Ghs just now (cgminer and pool), so back to 0.96 for me.

For those noticing that some of their units need to be warmer for better rates, I have no doubt about that. I have the same issue with my GPU farm of MSI TF 7950's. Some of the cards don't like being cold at all. The cooler they get, the higher the error rate and the lower the hash. The warmer, the inverse occurs.

For these cards, the sweet spot seems to be 75-82. Error rate is less than a percent, hash rate is easily 690+. Below 75 they slow down and error rate doubles or even triples.

It's the 28nm architecture.

Interesting, a chart on this page shows that 28 nm comparator sensitivity(perhaps to EMF?) drops and levels-off
at the temps we've noticed working well:

Neat link.

And though way earlier in this thread I was dogged for not being an electrical component design engineer while making some comments on design, assembly and deployment.. every now and then, it's as if I know what I'm talking about. lol

I predicted the 28nm would have issues if too cold. Looks like I'm partially right. One thing is for sure, they designed the cooling setup to work in hot datacenters, so it's no wonder some of these units aren't able to warm-up when used in houses.
