I'm mostly interested to know the full capabilities of the once thought to be obsolete S7.
Who said the S7s are obsolete?

So how do I enable ASICBOOST on these ?

Bitmain enables it....the extra hashrate is sent directly to their pool....I bet
it saves power. Thats why their miners are so efficent.
Back on topic, new T9 miner arrived today. As expected so far running perfect @ 11.7THs

Nobody will tell you...

Am I imagining things or did Bitmain just jack up the price of the T9 & S9?
When I looked this morning, I swear the newest batch shipping April 15th was $1050, but now it's $1150, and the S9 was $1156, but now it's $1296.
The T9 batch thats available now for $1150 is 12.5TH/s. The one sold for $1050 was 11.5TH/s When I looked this morning, I swear the newest batch shipping April 15th was $1050, but now it's $1150, and the S9 was $1156, but now it's $1296.
Does bulk order would be a lot cheaper?
I guess so... But you would have to send a representative to negotiate with them to get the best deal, otherwise they will just refer you to their website. Perhaps a big miner might give a better answer on this...

It's nearly impossible to run into profit with this thing, ROI for the unit cost is nearly 1 year, not yet count for rents, air-con, electricity and labor cost.
Bitcoin mining has become too centralized because of what you mention, mainly because the initial investment is pretty significant, for unit price and setup costs. Bitmain is too interested in profits to give smaller miners a chance at getting into the game. Plus the T9's 11.5TH is nowhere near powerful or efficient enough to give substantial enough returns for the price they ask. But running costs can be reduced if you setup in the right environment, as well as labor if you have the skills to do most of the work yourself. I think Bitmain just serves the big miners now, so if you're a small miner best to look into other crypto's to mine.

Back on topic here, Bitmain is shipping the T9 'ship April-10' orders now. Got my UPS shipping notice yesterday
EDIT: 8:00p, just checked UPS and the miner has already left Alaska! Should be here Friday.
I haven't seen a miner move that fast in months!

The entire bitcoin ASIC industry serves the big miners. Ebit, BW, and Bitfury dont even sell individual units.
Thats what altcoins are for.

new S9 batch is coming...

someone already know the unit price?

For you maybe. If so, don't buy itFor folks like me, it and its brethren do pay for themselves and generate profit in reasonable time just fine.

But either way, they are either selling a faulty product knowing that their customers are unlikely to even reach ROI, which is all kinds of wrong. Or they are selling second hand equipment from their own mine despite the law.
IMHO it is your first one: To squeeze out the highest possible yield of the 16nm chips Bitmain has seriously widened the QA window for what are "usable" vs good vs Prime chips.Looking at speed/hash rate spread between boards I'd guess at least 3 levels are used for binning chips to be used when populating boards targeted for highest efficiency miners (s9/R4). Hopefully humorous example would be 'meh', good to very good, and finally best. Given the typ yield of 16nm that makes for probably 2-3x more 'meh' to good (say >80% of cores work) chips than best (>90% cores work at full speed) grade so....
Tie that with lapses in board assembly quality checks... On the 2 s9 boards I had fail the placement and soldering of the VRM was -- horrible. Frankly, surprised it passed at all considering the module was rotated enough to be just literally a hair breadth away from shorting right off the bat. How/why that wasn't caught by an inspection camera, who knows...
With the T9 hopefully their sacrificing eff by pushing the Vcore higher is what results in otherwise 'good' grade chips performing as very-good or better. As to the board assembly - who knows...
Your assessment is plausible, and if its true, then Bitmain has turned into the MacDonald's of the Crypto industry, willing to sacrifice quality for profit. I'm sure they will start to feel the results of this approach soon if they keep it up. I guess time will tell how their T9's go, but I for sure will not be doing any more business with them.
