if you rely on bitcoin price increasing to ROI, you would make MORE and be better off just buying bitcoin and holding it..

Why is the new S9 only 12.5 TH/s?

Shitty chips that require a higher voltage to run stable.

are you talking about customers that ordered for the feb 20th delivery date?? because i didnt get any coupons for any of those miners....

Did anybody from the 20/Feb batch receive a coupon?

im interested in having this answered too....i asked but no one replied...you asked and no one replied again. if thats the case im owed a few coupons so far lol.

r u a troll?? i feel like u keep poppin up to flash you bit shot lifestyle around to everyone....the only problem is people on the interwebz know not to believe everything they hear. its easy to over embellish your numbers. i agree with you that btc mining is still doable with the right conditions and alotta luck with power costs/mining locations and experience that first hand every single day but at .10 per kwh your looking at not making much back if any at all. especially since most power costs are split into power and distribution costs so while your power cost may be .10 per kwh you distribution adds another few cents per kwh to the cost of running those machines not to mention cooling costs which raises the power. if i didnt have free power i know i wouldnt be mining and what your saying goes against all the bs you spewed in your previous posts....who bases roi on numbers that dont exist yet? thats not hitting roi...thats gambling and while thats up to you i have to say the other dude that posted is right....if your betting on btc prices going up to make money u should just buy and hold coins not miners. but thats assuming the miners are claiming to be buyer are actually being bought and used lol which im guessing thats where your fudging your numbers a bit but im a skeptical kinda guy.

Exactly why I went back to GPU's,in the black with 4 of em,paid off in 4 months.....go eth!!! 

Looking for next GPU coin to mine

[NotFuzzyWarm]

^^ Ditto.
Their site says 'cheapest price for a batch yet'. So wonder if us who ordered earlier will get coupons like the Feb customers did?

I see that Bitmain has dropped the Xilinx SOC in favor of Altera's (now part of Intel) Cyclone-V. Wonder why?

Not sure what their order/delivery timeframe was  but with the last batch that some folks made mention of getting coupons to make up for the higher price they paid for their early orders. I swear it was Feb. ones...

Anyone who got a coupon last round care to say what their order date was that Bitmain compensated for?

please help ASAP
I replaced the controler on S9 which I bought with bitmain. The hashing boards are working I checked them on another S9. When I powered it up it shows the hashing boards in status, first minute or so there are all 0s but also zero hashing speed, after couple minutes all of them are showing xxx. I tried 600 and 500 freq but still the same. What am I missing ?

update:
is there a chance that the miner isn't working with a faulty fan? even if I disconnect it?

Yes. Replace the faulty fan.

shipping from bitmain costs too much, any alternatives from ebay/amazon?

This is a good one, I used to have AvalonMiner 6.0 equipped with this.
Sanyo Denki SAN Ace 120 3.0 Amp 12 Volt 120mm PWM Fan 224 CFM
https://www.amazon.com/Sanyo-Denki-SAN-Ace-120mm/dp/B00QWB1X3O/ref=sr_1_1?ie=UTF8&qid=1488887739&sr=8-1&keywords=san+ace+120

This will git s9 I guess but isn't the cable too short for rare fan ?

There are different size of extension cables available
for example https://www.amazon.com/extension-cable-Black-Sleeving-FC44PWM-12BKS/dp/B0055OLY88

take measurements and see what fits the best

Thank you for your help, you saved me so much time!

No problem, happy to help  

If you have few miners I would give advice to have at least one spare fan all the time.
That way there is only little down time because of faulty fans.  

And this is of course for the 120mm fans. I have those but no R4 fan because that is god damn hard to find  

I bought it as you advised and it works great, but it shows under the FAN3 that it's RPM is 30.600, is it possible that it can't resolve the speed and is working on 100%?

Possibly, I must say that I have not run into this kind of problem.
Does changing the fan connector in use make any difference?

It just changes the order of display nothing more, but actually unless it's working it's fine, I was just wondering will it cause the problem or not

I refuse to support this company, I would prefer to halt my operation and wait for competition to enter the market. Than to offer my hard earned money in support of someone who wants to ultimately see the destruction of bitcoin as we know it.

I own a couple S9s.  I am super happy with them.  However, BTC I DO NOT WANT TO SEE A FORK!!!! BTC Antpool's unannounced adoption of BU may force a hard fork, effectively creating two block chains with the "real" bitcoin.  If that happens then BTC will likely head into a downward trend.  BITMAIN, a company which I support and mined at until the BU adoption, likely sees gains in the long-term and puts them at a competitive advantage if the price drops because of lower priced electricity.  

If you can split Bitcoin, then what value does it have?  There is only 21 million Bitcoin.  If we hard fork, there becomes 42 million.  What prevents another split in the future?  The fact that BTC will not be duplicated is where it has value.  If it can - and would likely - show up on two separate chains (1MB and 8MB), then nobody will want it until all of the double transactions are worked into the BTC or XBC.

I, personally, like a larger block size but not unless we get the SegWit people to adopt it as well. There must be consensus in any changes for bitcoin to remain bitcoin.  There is not consensus.

Another reason I'm glad I quit buying ASICs & mining Bitcoin...........leave the mining to the Corporate Professionals,they mine Bitcoin for a living & know better than you lowlife home miners what's good for Bitcoin!!!!!!!!

Support another coin with GPU mining....you'll be glad you did....& so will your wallet    Mine's gettin full !!!

Hopefully not full with pre-mined scamcoins.

Satoshi intended the hard-fork to deal with unsolvable issues like this.  The longest chain becomes bitcoin, the shorter becomes an altcoin.  If this issue does not resolve some other way, that's what should happen.
Bitmain gets to support client they want.  Miners (me) get to support the client we want by mining the pool that indicates it. 
I doubt Bitmain's owners are intentionally trying to go bankrupt.
The internet has been filled with bitcoin politicians bad mouthing both sides.  Ultimately I think this issue will be solved by a few engineers deciding how to move forward.
I know this is off topic. Sorry.  That's all I'll have to say here about it.

Interesting approach for the medium and long term.

Valid point.  They are expressing their right to say how they feel: "BU".  I still think they are a great company! I just do not want to see a fork. It  would simply be full of problems.

Ultimately I think this issue will be solved by a few engineers deciding how to move forward.

Right now. It is only signaling.  "Sources" say that they are moving the public 51% threat to a more realistic signaling of 75% for BU over a sustained period. Once a change was decided, there would be two weeks before the change actually took place. 

I think BU is the better solution for scaling (which I think BTC should do) and keeping transactions on chain.  We just don't need to see a fork.

I am considering ETH (not ETC, speaking of forks).

...  "Sources" say that they are moving the public 51% threat to a more realistic signaling of 75% for BU over a sustained period...

Any of those sources that aren't just you repeating hearsay from Kano?

The choices right now!  Bitcoin Core – Current, 1MB, slow transactions:

SegWit – Soft Fork, Efficiency
Bitcoin Unlimited – Hard Fork (Bugged)
8MB Blocks – Hard Fork - Long Shot and not really on the table

Currently the day to day use of BTC is becoming more and more limited.  Something needs to happen. 

SegWit would fix the problem without risk near term and give the core developers time to come up with a long term solution.  The problem with this is getting consensus among miners which is not happening due to miners not making the decision and the problem not getting resolved.

Bitcoin Unlimited would also fix the problem short term with high risk.  It has already proved to have a bug.  This is being done according to the system rules by forking into a different and separate coin.  This is the issue with "BITCOIN" having a duality in name and use.  Who would be the developers?  Many questions to include another bug and hurting the Bitcoin name while addressing the short term need for everyday use.

Your thoughts?
