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.

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.

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

Is sidehack dismantling one of these puppies anytime soon?

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 .........

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.

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 Tongue

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

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

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.......

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.

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)

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 !!!!!

Just go for a drip feed into the bottom connector (with a header tank and ball cock)(cold end) then let the top connector drip to a drain(hot end).
Total loss cooling is easy and cheap, so long as the water is free.
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.

Having problem on speed reading..anyone of you have the same problem?

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!

Evil beware: We have waffles!
Now that I'm more comfortable with the one board running 100C or a tad higher, got my batch-1 running full speed again Smiley

It took a few soft reboots to get all cards running on all cylinders. Mainly it was card-3 which kept only running ~ 3.7THs vs 4.5. But, once it started at full speed -- nice.

Im not suffering as much as you guys with regards heat, but its been pretty warm here in the UK last week.

Right. I got two large van radiators off eBay. I got two Ford Transit ones.
I linked the two together with braded hose and sealed up all the connections using jubilee clips.
On the inside one I covered it with a box and left some round connectors on it, to suit flexible ducting that connects to the miners.

The outside one is mounted with a 230V fan to blow ambient air over it.
I then have a pump that pumps water through a copper tube with small holes, to spray water over the coil in front of the fan.
The discharge turns upwards and makes the water drip back down into a tray to re-pump over the coil.

I filled the radiators with water and used a central heating circulator to pump water between the outside and inside coil.
Gives a massive temp drop with the water spraying over the coil.

When the water heats up, dump it and charge the tank with fresh cold water.
In the UK im getting approx 15 Deg tap water.

Currently working on an Arduino with a temp sensor to monitor the water then dump when it gets warm.
Just a solenoid valve to dump with a simple ball cock to fill with cold water again.

Miners suck air from over the indoor coil which cools the incoming air significantly.
The adiabatic cooling to the outdoor coil really works.

Im hoping to build the thing properly in some stainless steel boxes and install it permanantly over the next few weeks.

Just go for a drip feed into the bottom connector (with a header tank and ball cock)(cold end) then let the top connector drip to a drain(hot end).
Total loss cooling is easy and cheap, so long as the water is free.

It seems that one of the board in my miner always start getting more HW errors than the rest. Anyone is experiencing that? For example now (chain 1: 18 HW, chain 3:28, chain 4 :220). Usually it runs fine for some time, but after it last board is getting much more errors. I just want to confirm weather I should try to get the board replaced or there is any other thing I could try?



Thank you for any advice

I think the 3rd board always on the S9's are all producing more HW errors than the others. Most likely because of the heat and case design and air flow.
All of mine are like that and all the others I have seen are the same.

Ok thank you. Wasn't sure if my board is not broken.
Thanks for this. I just got my S9 this week, and I'm happy with the hashrate, it's a great machine. Didn't notice that the third board had more HW errors than the others until I read this, but have checked and mine is like that too.

I'm also seeing 10x HW errors on the third board with my B3 S9. Been like that from the beginning.

Looks like it's a very common situation. Assuming that they didn't consistently place crappy boards in the third position, it's likely an airflow/design problem (as others have suggested). Good thing that the other boards compensate for the "bad" position.

But given that we're past batch 9, it's clear that Bitmain isn't interested in using our feedback to improve their design. This problem will never be fixed.

Not that it matters. Seems like their main focus is on controlling supply and managing the difficulty.

For a while now I've wished for competition to break Bitmain's current monopoly. But in retrospect, it's probably a good thing for little miners that a competitor has not emerged. If a real competitor surfaced now, Bitmain would just slaughter them in a price war, and the little guys (me included) would be crushed by the increased difficulty. In this scenario the halving drop off will likely be too short lived to be much help.

 

Every difficulty jump that stays under 213 works for a smaller guy like me.

My solar array is low cost power, but has a power cap.  say 8.4 kwatts.

So if diff goes to 400 I hurt at 500 I hurt more.

Frankly bitmaintech has played the s-9 exactly as I have hoped for. Making a profit more and more likely as time goes on.
