BTC.COM (also Bitmain owned) is 0% fee and pays transaction fees. They call it "subsidy." No guarantee how long it will last. Plus it's PPS.

That sounds like the best payout/lowest risk pool out there. I'm on Kano. I may point my new S9 to BTC.com, but I really prefer to stay outside the Great Firewall.

That's my thinking. There is no other pool I know of the has 0 fee for PPS. And getting the fees on top of that is real nice.

EDIT - And they are merge mining Namecoin too.

be VERY careful with PPS pools that dont take a fee.. they will eventually go broke and stop paying out. it only takes a couple of long blocks before the pps outweighs the block rewards.

How is that possible? Maybe the higher S9 prices? This PPLNS is good when it's good, but not steady ... been 48 hours.

Not going to retyped it all again so ref https://bitcointalksearch.org/topic/m.17968291
Done that way each cable is protected plus easier to wire and fuses cost less.

I hope I got it right sir. Is this what I should do for my S9? Put a 35a fuse inline with the positive 3wires going to the Hashboard?

How about the controller? Do I need to fuse it also?

instead of going from the psu you could do pci-e on both sides so they plug right into standard cables..
i think many people on here including myself might purchase a premade set of 9.

also you might want to use something like this for the fuse
im not sure if you need 20 or 25 amps tho..

Could someone please do a quick "ps axf" or send output from the "monitor" gui tab on their hashing S9 miner (autotune version?) to see the command line options for launching bmminer. I am still struggling to get this machine start hashing again... ;-/

Appreciate the help!

Only thing I would change is the fuse size. For a s9 take it down to 20-25A per cable.

Give that person a cigar, they got it right!

As for the controller, while there is nothing there using very high power and I don't ever recall reading about one catastrophically failing on an Antminer actually it *would* be a good idea to fuse it. Because the fans pull a fair bit of current - like up to about 2.5a each at full speed - I'd think an 8-10a fuse would be perfect.

Perfect sir! Thank you for the cigar!

Have a great day.

No measurements done yet. Still trying to get the thing to actually start hashing... Undecided

I'm just curious if it could be not getting enough power? Huh

Power is fine. After leaving it running over night, it actually started hashing. Not sure after how long and for how long (no stats available). Clearly this is crap and is not the behavior it exhibited before the hard reset. I am guessing there is a quirk in the recovery firmware, which needs fixing. Maybe a script or something. A timeout maybe (sleep 20s?). Has anybody ventured into the linux filesystem and looked at things in detail? For one it would be interesting to start bmminer manually and see what happens. The single-board-test program seems to do rather little.

Not sure if the thing really *was* hashing. After 1h30 it is still not hashing and the "sleep 20s" is running, at some point this seems to change to "sleep 20m". The log shows 2x63 asics detected (2 boards powered) and all seems well, but the bmminer is not starting. Does anone have the commandline (from ps axf) to start the miner manually?

Further reading has revealed that the "single-board-test" seems to test the pic firmware on the hashboards? Well, surely this does not take more than a few minutes and if there is a problem there would be an error message to be found somewhere...

Why would a hard reset cause such problems?

What are the recommendations on pools for a single S9 miner at present? Eligius seems to be de-funked - it was a nice free anonymous pool with useful stats...

Bitmain's pool? They seem to have a charge. P2pool is not an option at the moment.

Thanks for any info.

Kano or Slush for example..

BTC.COM (also Bitmain owned) is 0% fee and pays transaction fees. They call it "subsidy." No guarantee how long it will last. Plus it's PPS. So you get paid consistently. If you started with them back in October when they took over the domain I think your cumulative payout would be around 103%.

What does this solve that a high quality PSU doesn't?

It solves the problem of what happens from a short circuit. That short will draw all available power from a PSU. In a heartbeat the voltage will droop and more than likely the other hash boards will drop out giving the entire PSU capacity to feed the short ciruit. That set of cables/connectors feeding the offending hashboard burn.

The only thing ANY PSU will do in that scenario is supply all it can until it overcurrents. That -- takes time during which things burn. As in flames until the PSU shuts down.

Overall to me, this is really more of a concern when using a several-kw supply to feed 2 or more miners eg the 4kw monsters. 333A of sustained current available and probably a short duration margin capacity for 150% of that...

the batch of s9's that were slated for a feb 20th delivery run faster and quieter than previous generations as far as i can tell. so quiet in fact i can run one in my house without hearing it all the way on the third floor when its running in the basement! it uses a little more power but its just there to heat the downstairs during the winter so the trip to the washer and dryer isnt so bad (tile floors and bare feet suck in the winter time lol). the rest of my s9's run in temp controlled rooms with dedicated ac units but so far not one of my s9's has gone down except for one that tripped the breaker on one plug because it wasnt able to handle the power draw. after replacing the wall socket with a 20a socket with 2 plugs and hooking everything back up it fired back up and has been running great. others say they have issues with all generations but i havent and i have almost 30 s9's running and buy them as i get the btc from mining so my generations are all spread out.

Anyone noticed that bitmaintech's site is now unsecured. Their SSL cert expired? Any word from bitmain itself? Are they even aware of this?

--edit-- nevermind, it seems bitmain is not using the bitmaintech.com domain anymore that's why.

Use bitmain.com instead.

... hard reset using the "IP report" button brought the board back to life.

The miner must have been stopped in an unlucky state and was unable to initially complete the reset procedure.

Now is it sitting there, waiting to start up the miner daemon, which supposedly takes a while sometimes. 17min and counting...

I'm glad you got may have it solved. I did a couple accidental hard restarts and now it's hashing upwards 13.7 from 13.6. Hopefully you'll have the same luck!

Do you have a Kill-A-Watt or something to monitor the PSU? I assume it's getting 1600W ... when mine was idling it was only pulling 0.5A, then 1,2 and a spike to 12A and 1400W (on 110v) as it started hashing.
