Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 269. (Read 531168 times)

I wonder if they will drop price a lot say 1500 or if they go with the 1800 method.

Coins are low about 600

Bitmain Sales told me on skype they will put them back on sale "in a few days"
no price and specs

With BTC currently = ! 610 USD that may take awhile... Eeep!

Or... they are fulfilling order for mega customers like https://bitcointalksearch.org/topic/m.15721138 and https://bitcointalksearch.org/topic/m.15764113.

Not to mention of course probably Hashnest.

"Several thousand s9's' is a helluva lot of chips and with TSMC no doubt having a monthly production limit set for Bitmain's boutique ASIC's, well you get the picture...

Bitmain waiting for the value of BTC to hit 700 before they release another batch of the s9  lol

Thanks for the info though. Was not sure, because there are really good miners released by some people and they are locked only for bitcoin mining.

SHA-256 ASICs will work for any SHA-256 algo altcoin.

Keep in mind the most recemt ASIC's have a tendency to choke on the low difficulties presented by most altcoins, running all possibilities of given hashes + nonces and sometimes crashing the miners.

Coins I know of with reasonable difficulties (>1M):

Aurora, Digibyte (SHA256), Unbreakable, Terra, Neos, Digital (SHA256), Maza, C-Bit, Join.

Keep in mind profitability for these altcoins fluctuate wildly, check out www.zpool.ca.

So I can mine only Bitcoin with this miner or every coin that is SHA-256 supported?

Hm... Running the hashboard on cgminer is a lot more of a software problem than a hardware problem. There might be enough info out there to build a USB adapter to the 18-pin cable with a micro on it. Take some time, but not impossible. It'd probably be easier to just write a cgminer for the native controller but that's difficult without any real chip info or hardware info like might be available if they released bmminer code which would solve the problem anyway.

Just guessing here, but if they are selling software that is in breach of the license agreement, doesn't that mean it is counterfeit?  If so, sites that are selling counterfeit software can be taken down with a simple DMCA request. It might seem a bit extreme, but if their site was taken offline it would hit both their sales & their reputation(?).

I'm sure they would quickly release their source code once that happened.......

10 x 1172W =11720W x 24 =281,28 kW/h per day + 12% = 315 kW/h per day

11,85x 10=118,5 TH/s per day

1 TH/s earnings per day  0.00117783 BTC    (PPS )
118,5 x 0.00117783 = 0,139572855 BTC per day minus 2,5% PPS fee = 0,136 BTC per day

Antminer S9
1. Hash Rate: 11.85TH/s ±5%
2. Power Consumption: 1172W + 12% (at the wall, with APW3 ,93% efficiency, 25C ambient temp)


With electricity prices 0,1 euro per kW/h , each miner's profits are 5 EURO per day   (1BTC=590 EURO)

Kind of makes you want to reverse engineer the S9 hash boards and just make a rip off version.
A European Counterfeit S9, that would be a laugh .........

Lulz ... ... ... "an undisclosed amount." ... ... ...

Most have little to gain.  These types of issues are usually resolved with "an undisclosed amount."  Has any type of legal contact been made?

KANO is right, it is unbelievable that we do not make a big question mark re. the Cgminer license and what is going on inside BMminer.
I feel Bitmain is very cruel when they do things like that and nobody cares....it's the freaking ecosystem they bust.
Let's see what the statistic says in a month time re the BMminer, but after 14 days the BMminer doesn't seem to perform as well as cgminer 4.9.2 in finding blocks... actual it looks like someone a little more skilled than me should try to dig into this.... Did Bitmain release a miner that puts out a lot of hash but is only able to find bloks as well as Cgminer when used at Antpool ?

I know its too early to tell if it is the truth, but 14 days running at a rather large pool, the pool reports shows that the worst performing miner is BMminer.
Cgimner 4.9.2 is first, then 4.9.0, third 4.8.0, fourth Nicehash 1.0, Fifth Cgminer 4.7.0 and then last BMminer.....and thats even when BMminer puts out the dobbelt amount of hash comparing to Cgminer 4.9.2 !!!!!

How much can i mine with this miner per day. I am planning to buy 10 such miners. I want to know everything before buying this miner. If possible pm me. How much btc it mines per month and whats the maintenance cost(mostly electricity)  of running it for a month. And how much will be estimated profit from it.
Is it really profitable?
Thank you in advance.

So Bitmain have again broken the cgminer license and not released the source code of all their changes within the requirements of the GPLv3 license.

Though it's obvious most don't care about that and will keep buying these things

It is and would be easy. My S7's are in my workshop premises and we are on a water meter.
Being involved in energy efficient systems I cant bring myself to do this because of the water loss and costs.

In about 2 to 3 weeks ill post a "How To" with photos of the whole thing and some temp readings.
Further, im going to control the water cooling (Adiabatic) by external temp to further add some efficiency.
Pressurusing the system to maybe 1.5 Bar will also increase thermal heat transfer.
Next is to find a circulator pump that can be run from a small solar array, and battery so the energy to drive the cooling is kind of free.

Im also pretty sure that spraying cold ish water over the external coil wont suffer from the same problem of evaporative cooling would with high humidity.
Most of the time in the UK the unit will run just ambient and should work fairly efficiently.
The big crunch will be when I stick the S9 onto it and take it out of the server room.

Ive also just seen a post on here showing some rack mount shelves that the S7 and S9 fit into perfectly.
Maybe now time to build the internal coil directly inside a spare 19" rack cabinet, that kind of gave me an idea rather than using ducting.

Ive just put a couple of orders out for some raw materials to do this thing properly now that I have had it working.
Looking forward to a proper build, putting up a how to, photos and temp readings.
More importanly solving my heat problem for a low running cost.

Is sidehack dismantling one of these puppies anytime soon?

When I first got my batch 3, the hash/HW/Chip Temps shot through roof on one board (3rd board, I think) during the initial boot.

After reboot from within the GUI, it came back to normal and has stayed pretty much within what is considered normal on these miners ever since.

Good luck!
