Probably having a senior senility (brain fart) moment, but, what hash chip(s) does Innosilicon make that are appropriate to Bitcoin hashing?
They made the A1 Booster, aka Bitmine's CoinCraft A1 - and the A3 is likely to be what the LK Group will be using as their 14nm solution.
(you can read about the drama between those two+ companies, if you're bored; later posts turns into a mess about mostly unrelated things)

 The drama was between BitMine and Innosilicon, Lketc wasn't involved as such.

I'm no longer legendary just in my own mind!

Ah, glitch of an early edit - that was supposed to refer to just Innosilicon and Bitmine (the + referring to AMT)

I've been meaning to look into what they're doing for chips. The A1 was about twice the power that I'd like to see from a single chip but they were definitely turned into some pretty good gear.

Where can I find a datasheet/specs (prelim or otherwise) on the A3?
I guess you'd have to ask them - beyond their claim of tape-out and "over 60% power saving over [A1]", I don't recall seeing any solid public info from them.  Presuming it is the chip LK Group would be using, they lay claim to a future 5Th/s, 1kW miner.  BW.com claims 0.26W/Gh. Either would fall under preliminary at best.

I asked.

sidehack - didja' get my cc?

I received both and replied. No offense, the various gentlemen which alert me in this thread to messages in other places, but everythings ends up funneled through email so I see it all at once and it's kindof a waste of time to get three messages about the same thing at the same time from the same person in the same place.

On the BM1384 Project Dev front, I just got an email from Bitmain saying there were no details yet about new chips. Not terribly surprising. There's background chatter with InnoSilicon and Canaan-Creative and hopefully some of that will turn up info. I'm taking care of all the manufacturing tasks at the shop for at least the next week or two to give Novak time to focus on the three different projects he needs to wrap up before month's end, and when I get stock caught back up I'll get back to board dev. Next step is testing some new level-shifting I sketched up a while back, and then getting a barebones 18-chip board functional (off an external supply, probably the hacked TPS53355 circuit). It'll be run off an S5 controller until Novak's got multi-chip code of our own figured out, but that likely won't be for a few weeks. I'll be ironing out some buck designs and working on peripheral controls (fan, temp, voltage etc) for a basic pod miner board, which would translate directly to larger boards.

I also need to codify and post for discussion our ideas for a more-or-less standardized modular rack-scale miner. It'd be something we intend to build boards for, and intend to be flexible enough that others could just as easily build boards for it, and ideally that different boards from different people, even using different chips and topologies, could all be run together with cgminer support being the only real limitation to worry about.

Also, I just noticed that one of the four sticks I had running at 275 (15.1GH) pulled a 208M share sometime in the last few days, which puts them, by highest share, well ahead of the S4+ that's been running since Saturday (46M).

I've got a few nanofury usb sticks and every now and then they'll pop a share that beats my S3+, but it's pretty rare.

My winter heat Dragon pulled about a 3.4B share once, but the diff was already a few times that. I think I've marked three shares over 1B so far but no blocks. A friend of mine hit a block on an approximately solo pool (it was his own pool and he was 95% of the hashrate, I was the rest) end of 2013, which was pretty cool.

Compac PCBs have been shipped (earlier than expected) and I'll probably have them in hand tomorrow. We still have no word on the pick-and-place but as soon as I'm done with the big PSU order I'm grinding on I'll be trying to get a head start on Compac assembly. I need to check on heatsink delivery date and get a parts order sorted.

I don't think I've ever hit a block on Bitcoin, but I did hit 4 fairly early on with my Gridseed 80s. Even 20/20 hindsight says "no guarentee I'd have done that solo mining" though, but it WOULD have been nice.

Innosilicon doesn't seem inclined to go into the farming business.
There is still hope!

Not picking on you, but the key word and operative phrase in your statement is "seems".

There is no evidence to indicate that Innosilicon is or is not operating a farm.
Innosilicon has in the past manufactured complete miners and I imagine there is some "burn in" testing on those machines.
How long is that "burn in"?
A day, a week, a month, . . . .

And even if it's only a day at Innosilicon, when their customer (who intends to re-sell them) gets the machines, how long do they "burn in" test them before selling them as "new".

Based on TRS's info, I queried Innosilicon on the availability of 14nm hash chips which per their post alluded to indicate they had taped out a production run.
Their response indicated:
1) they had taped out a test chip run (unspecified quantity),
2) they were unwilling to sell 100-1,000 chips (test or otherwise),
3) they were soliciting "large" pre-ordrers, and
4) were interested in designing/building/supplying a custom complete miner.

Needless to say, PlanetCrypto as a company isn't interested in pre-buying vaporware chips (due to time/value of money calcs where the time parameter may approach infinity) and the belief (which has a basis in fact) that Gekkoscience would design and produce a superior hash board.

Added to this, if we purchase hash boards from GS versus a company in the Pacific Rim our shipping costs are significantly curtailed, interfacing with American customs is obviated, and GS has a history of supporting what they sell.

So bottom line, if/when Innosilicon has 14nm chips for sale, we would consider buying a small quantity (100 or less), forwarding them or drop shipping them to GS if they were interested in designing a hash board which they may or may not decide to put into production for general sales to the community.

If the GS hash board using the Innosilicon chip is a profitable unit, we would then purchase a "large" quantity of chips and contract with GS to be our vendor of choice board supplier.

Till such time as all that comes to fruition, our focus is to continue plodding forward with a community designed and owned 14nm hash chip.
