What do you guys think of the antminer r4? Thinking about buying two from usa (im uk) and running them on kano pool

Is it worth the investment?
I know s9 will have a better watt/th ratio but these will be run at home were i have to pay electric
My other miners i run at work were i dont pay
Also do u guys know any reputable company's that stock the r4 and ship uk?
My biggest problem is the import tax Sad

depends on your circuit breaker config at home. 
1x S9 draws 12A at 110V or 6.2A at 220V which gives you 13.5TH

1x R4 draws 7.7A at 110V or 3.9A at 220V which gives you 8TH

S9 is the most efficient miner ... so if you have the amperage availability - S9 is the choice. (noise & consumption aside).  Especially since S9 prices have stabilized recently.

If you have power outlet limitations from a current perspective, then R4 is feasible.  Just note you are sacrificing efficiency & cost, for convenience of fitting in with your home breaker config.

Well, I give up... The Android App doesn't send me a new Block notice, the other web based tool doesn't send me a new block notice.  Seems nothing does.   So I just decided to fix it myself.

I created a little perl script that reads the pool API and when a block change happens it will send me a pushover notification!... Problem solved.

I don't know how fast is *too fast* to ping the API, so I've slowed that way down for now. (2 mins would be min notification time).  I use Pushover for a bunch of other things and it's easy enough to use so TADA

I did make the little pushover app subscribable.  I want to run it for a block or 2 (my incentive to make them happen quickly), just make sure it works ok.  If so, and there are others interested, let me know and I can provide the Pushover subscribe link.

yeah, maybe now I'll get a notification of a new block found!
I too built minergain.com for this exact purpose - plus a whole lot more (including tax prep needs and eventually wallet valuation) since I mine on multiple pools.  I am checking with the kano home page every minute and when it changes and the immediate notification is set, it sends right away.  I am thinking I will change it a little bit so that I can also get the payment amount on the email as well - but it may delay the notification by another 10 to 30 seconds.  Not sure what kind fo information people would like to see on the notification email / text.

I would stay away from the R4. I have two of them and both lost 1 board. One after a few hours and one after 6 months. If you read the R4 thread, https://bitcointalk.org/index.php?topic=1597639.0 its full of similar stories.

Unless you just want a space heater, or they are super cheap, I would buy something else.

I have free internet where I live. I have never bothered having my own service hooked up because of that. It has worked perfectly for netflix and such. However, with mining, I see that my miners are bouncing back and forth between this pool and my backup alot. and I am running 4% stales. That is alot of hash thrown away.  I guess I need to get a connection of my own after all.

I think he's just going on the .9% fee, as that is all that kano makes besides his own miners. 
And I have heard directly from Kano that he does not run his miners unless he needs his house warmed up.  All of my discussions with him demonstrates that his primary mission for this site is the heath and future of bitcoin.  And yes, he probably does all right with the fees too - although having close to a dozen servers around the world is also not free.
Heh - there's a lot more than a dozen Smiley

This month I've been spending a lot of BTC on getting the hash rate up ... it's working ... and I'm losing lotsa BTC Cheesy

I've come up with another idea about throwing more BTC at getting the hash rate up - targeted directly at large miners - since we need a number of miners in the 5-10+ PHs range.
Once the accounting is done and verified all OK, I'll sort that idea out.

Of course all this BTC I'm 'throwing away' is BTC I've got from the pool fee, so no better use I can think of it!
... other than paying for servers and so I can survive ... and anime Smiley

I like it kano, would love to have double the hash rate.

I can only speak from my experience, but I've had 3 R4's running here in the basement for about a year with no problems. I chose them for my situation because they are not too noisy. Been mining here on kano with them the whole time and have about 2.5BTC to show for it. Not a huge sum, but I think at least as much as one would expect from 25TH. I have been quite happy with them.

Yes but why would the fan show it’s running 30k rpm if everything’s is fine? My S9’s ramp up and down. One between 5-6k and the other between 4-5k. Temps are mid 70’s. I don’t think that fan can even spin that high. It has to be a false reading and that would explain why it stops hashing.

Peck. What psu are you using? Have you tried a different one?

I am using the bitmain power supply... 220 V

But the power supply on that particular S9 machine is not the new apW3++

SO I will swap power supplys and see if that helps ..  Thanks for the idea!

I just have a hard time believing it is getting to hot... I have miners ranging all over the place from mids 70's to pushing 100 (all in the same exact location)

Does not seem to make any difference to them... lots of people on bitcoin say they run them up to 100 degrees with no problem..(I'd prefer they not be at that but it cant be the room temperature if some are completely cool and some running that much hotter?

Maybe it is something to do with that 13.5 batch?

Running out of ideas... I am running some cooler air back there now but does not seem to change much...

But that machine would stop hashing before, now it keeps running, just those fans revving up and down...

Not sure what is going on with that fan speed reading..my guess it it a faulty reading...

Thanks for all the help!  Will let you know what I find out...

Is it possible to go back on the S9 firmaware to the older versions where I can control fan speed and freq?

Again thanks to all!!

Switch the PDU/PSU, see if it follows it or stays with that particular s9.  I have three of them and one runs a little hotter and "faster" than the other two, no matter which PDU/PSU or 110/220 I try.  They're not all built the same.

Yeah something like that is on the todo list - I mentioned in the dark reaches of the past pages Smiley
https://bitcointalk.org/index.php?topic=789369.msg29277298#msg29277298

The 5Nd point isn't a simple calculation, it can change every millisecond, and takes a couple of seconds to determine.
Instead I'll have the system keep track of the last 5Nd point based on the last complete shift.
Thus it will be (in)accurate within, on average, about 25 minutes - which should be close enough.

Order an 821, or wait a bit for the 841. I gave up on Bitmain quite some time ago.

These miners are a case by case basis too. I have some machines that are overclocked and have not had one problem and others I have to turn the frequency down a bit and set a min fan % to keep them cool or they will lose hash boards. Dust and debris will hinder the units from dissipating heat and heat seems to be the big threat to these. I don't know if the S9's have the same problems as the S7's but if the heat sink is loose, it will not pull heat from the boards so the fans can move that air. If you are having hash problems as well, then you have other issues beyond the fan, though I've swapped for higher rpm fans and have remedied some heat issues. That or turn down the frequency and see what difference, if any, you see. It could have a weak power supply too, but you won't know until you can do more diagnostics.

Nothing happens until something moves.
