I think KNC's achievement is great. The extra hashrate is more than welcome given the recent spike in difficulty.

Yes, this will compensate my bet lost on their delivery date, not worst case scenario...

Good sir, I advice you buy some BFL hardware as cure for your problem!

please, stop comparing KNC and BFL. at least in this thread.

500GH but 20% of hardware errors. It's better to lower to original 400GH and have more efficiency at 1% HW errors.

Actually according to the video they are running at diff=127 so about 18mil accepted shares and less than 1% errors.

But does the HW errors increases a lot when you overclock, that would be bad

What use is a signature?

there's no public news at all about pick-up nor for delivery, hopefully they will tell us something during the day

Those hardware error share are also diff=127. So accepted 18mil shares and 3.6mil shares are hardware error. Let's be honest...

The real story here isn't "ROI or no ROI?  Ship 9/30 or 10/3?"  The celebration and the sour grapes, the sore losers and the ecstatic supporters, the assholes and the gentlemen, that's all fun to read.  But IMO opinion that's not the story.

The real story is the presentation of a functioning IC entailing leading edge technology in a period of time far less than they'll teach you in school is even feasible.  

Every time some information came out, it was met with armchair experts who pontificated on the folly of it all.  It's all in the 600+ pages of this thread:  "The package is ridiculously large; OrSoC must be idiots."  "The power consumption will be way off the scale."  "They can't come to market without the test sequence. It's going to be a disaster of BFL proportions."  "They're too small to produce in size."  Best of all:  they're Swedish, how can they possibly do high tech?

Spending a significant part of my life in venture capital analysis, I have to say:  while there were no red flags for me from a business or technical standpoint, I didn't think it would happen this close to schedule; too many moving parts and supply chain issues to be certain.  

There are still red flags, I'd say, in both CoinTerra and HashFast, but I'm not going to discuss them.  They will be what they will be.  Instead, I'm just sayin' to KnC's professionals:

Spectacular performance!

Yes they are. HW errors are those share that's not validate on CPU but are reported by hardware. And in this case all shares reported are diff=>127.

And what about the 5V connector.

Should I buy a 230V to 5V DC converter?

Guys, the units were just turned on and not tuned yet. 20% errors is unacceptable and they know that. But the units have to be tuned first.
They are not shipping units with 20% errors.

I do hope the hashing speed showing now on that test account is a result of further tweaking/oc . It's showing 650GH/s pretty constant now, with spikes @ 700+

Edit: showing 900+ now, so more than Jupiter hashing there :-)

The mining software determines the diff shares reported back to the pool.  The hardware has no idea what diff is, it hashes nonce ranges.  A hardware error not is a diff anything...

yeah there's a lot of think that has to be sorted out imho, let me summarize my own list:

- Is a 850W PSU really enough for a Jupiter? (in the 'orama video (1) I saw the power consumption at wall was 843W)
- Do we need a 5V connector?
- What is the delivery ETA for day 1? Or looking at it in another way how long does it take to do the last tweaking to the machine?

Sorry if this is a repost havent had time to get through old posts yet -

Hashing @ 500GH - http://www.youtube.com/watch?v=BgS6JBb4r1g

And shipping today!

sorry for bashing but if you don't have time to skim the last few pages just don't post

Last few pages... try 25 some of us do have jobs and cant spend every minute on here, as much as I would like too... I also figured that since the video was only uploaded 24mins before I posted it was pretty fresh... turns out it was a duplicate video with a different name!

If so, it ruins whole idea about vardiff, reducing bandwith (between device and software, at least). I didn't look at cgminer code, but I would like to hear from ckolivas about that matter...

don't take it personally, really.

I was just trying to maximize thread's SNR. Anyway I know that not everybody has the luxury to waste time to follow the thread too closely, but posting redundant info like you did, make it even harder and more time consuming.
