As most of you understand, only low power chips will work this winter and only those who have such chips will do profits in near future.

I would like offer a best ever miner design in exchange for such chip. What I mean of 'ideal miner'. Manufacturing costs for miner will be only around 1/5 of overall price. 4/5 of price will be net cost of chips.

Miner will run at high voltage with great efficiency ~95%.

Miner can work with nearly any chips, but I'm searching for best chip ever.

I have prototypes for different current chip manufacturers, so I can provide proof if needed. Also I have a farm for personal use that employ such technology.

PM me if you have great chips to offer, only with working samples.

I don't understand this, of course we all want more efficient chips and miners but you make it sound like its mandatory to go lower on power usage this winter (when electric prices are down and miners heat the buildings) or fail to have a profit, and i don't see it that way current top line miners will still be profitable this winter.

Good luck with your venture, but I'd imagine that a company with engineers smart enough to make a chip with this level of performance would also have worked out a design for a cost efficient system. Your pricing ratio presumably doesn't include the costs of PSU's?

no one will give or share a working prototype of a .3 watt chip.

If I had some in hand  I could sell them for 1,000,000 usd

Frankly the .3 watt chip may be like  unobtainium.  The rarest of all elements a little humor for a sat afternoon. 

As of today no one has shown that they have a .5 watt chip maybe the sp30.1 from spondoolies can do it maybe not.

You are little bit wrong about smart engineers. It is like producing devices and hosting devices. Sounds similar, but in fact completely different business.

I "sell" design for cheap. Many times cheaper then develop it, because I have it already.

Yes, my pricing ratio includes PSU!!!!

My current, not so good 40nm chips run @.63 watt
Maybe you are right, maybe not.

has anyone tried undervolting bitfury Rev1 or Rev2 chips to their minimum voltage range? its like 0.5V for R.2 and 0.6V for R.1

i might just do that with a nanofury if i can find a drop in replacement for the vreg

Thanks to legkodymov.
S5 was based on legkodymov's serial power design, and its power consumption at wall is 0.51W/G.
S2-replace PCB will be released after Chinese Spring Festival, and it will be serial powered too, and its power consumpiton at wall will be less than 0.4W/G.

Interesting (and slightly confusing due to poor translation) news from Bitmain in an ancient and forgotten thread.

More interesting is the fact that the OP wasn't a total crackpot... as anyone who had read the thread in the past surely thought.   Wink

So, it wasn't based on the OneString or those Yaizo (sp?) boards or the Prisma or a couple other string designs that had come out several months or a year earlier? I don't know of anything the S5 does that's truly novel design.

Will these be sold like the S2 kits; or as boards only requiring existing blade heatsinks / S2 backplane & controller?

Awesome stuff..

Now on a totally different note..

Seriously, how many freaking festivals/Holidays do the chinese people have!? - and every time, they seem to shut Down the entire country for a week.

This one is THE ONE. And the entire country is shut down for ~2 weeks effectively that time.
The other festival is the "golden week" somewhere in October, which is roughly a week.
