KanoPool since 2014 🐈 - PPLNS and Solo 0.5% fee - Worldwide - 2437 blocks

[VRobb]

Expected is actually the # of blocks we expect as of the last block found.  As to extrapolating to the end of the month, both the pool's hashrate and the Nd will change during the month so it'd be more of a guess.  As Kano-san has it now, it's a direct measurement.
Mine on!

You know this is the second time I buy a control board to replace and first time I got one on eBay and ended up paying like $185 with express shipping but the bastard didn't even had the board on hands and ended up sending it to me 20 days after I've made the payment!!!  And I've received it like 27 days after . I was so freaking pissed because I've lost like $400 while waiting for it!!!   . This is the sellers name by the way "kurniaboss888".

Anyway after another miners control board broke i stared looking for another place to buy because there is no way I would wait that long again! And pay that much when they are like $70 from bitmain (of course they never have it in stock).  I found a guy on Aliexpress and here is the link to the board itself...  

https://www.aliexpress.com/item/kuangcheng-s9-control-board-Applicable-to-ANTMINER-S9-14T-13-5T-13T-12-5T-12T-11/32828043453.html?spm=a2g0s.9042311.0.0.iP2lmv

I bought 3 from him on the 5th or 6th and they are already in the Local DHL so it was fast!  I payed $77 for each and like $30 for the shipping of 3.  Although I just checked when I was copying the link for you and he changed his price from $77 to $99 but I think it's still is better than an S9 just sitting when it can make you that $100 in a week working.  If you like I can PM you tomorrow and let you know if what I got is good or not.  

Yes, please let me know if it works. I see that is a 1 piece board. Where as mine is a two-piece. Would installing that one piece make my miner "auto-tune"? I really don't care if it does or not. It will just be nice to get back on-line.

Thanks for letting me know!!

EDIT: I quess I will be flashing the miner/board after installation with the appropriate firmware. In this case, 600MHz

No problem my friend!  I'll let you know as soon as I get them and install one.  Don't know if it will fit your miner, I've never even seen an S9 with a 2 piece control board.  In mine it just slides out after pulling back 2 little metal locks on the sides (One board) At the same time I'm pretty sure it is compatible and will work as long as you manage to install it on the miner somehow.  In my opinion it should work and auto tune the hash boards that you have as long as your miner 11-12, 12.5-13, 13.5-14 th model.  But you should Definitely consult the guy before you buy and I'm sure he will tell you.  In any case the buyer protection is working on Aliexpress and you will get the money back if something doesn't work but you need to ask first.  I bought some new bulbs for headlights once and they were like 2 days late so they gave me the money back.

I'll let you know.

Had to do a little rewiring due to a 60 amp fuse blowing when I tried to run my electric clothes dryer.
The dryer is now on a separate circuit from the bitcoin miners.
The bitcoin miners are chugging along much happier now.
I lost several hours of bitcoin mining but thanks to the method of payment at Kano pool the payments only varied by a small amount.
The cooler months are in the near future and I will probably bring my S7LNs upstairs if for no other reason than to replace my wife's heater in the bedroom. After all, if you are going to heat with electricity it might as well be generating bitcoins!

On another note, Canaan is out of stock on the A741 as single unit sales but not out of stock for large orders.
I understand their hope to make more money with less work but this leaves me feeling a bit left out as I can
not afford $43000 or $49000 for a group of A741s
Lets hope they bring back single unit sales soon.
I hope everyone is staying high and dry as the weather disrupts our lives.

Yes, I'm sure it will work on mine. The newer control boards are all one piece. Bitmain sent me a link to buy one this morning and wanted $60 but said it will ship within 20 working days. I don't want to wait that long and will spend the extra $$ to get it in a week. Mine attaches the same way as yours. My old one just had an additional black board that plugged into the green The new ones do away with the black board and everything is self-contained on the green board.

Thanks so much for the info!

I apologize for being a bit off topic, but I'm trying to get an additional S9 hashing on our pool.

Hey guys.....I've had my two 741s running about 36 hrs now with no interuption, but decided to shut them down now as the storm is making it's way thru Georgia....being the noob I am and not really up to speed on 5nd....how long before I need to come back up before it affects my numbers......thanks.

Going off-line will start effecting your 5Nd immediately. It will start dropping slowly at about the same speed as it ramped up.

If you can get it back on-line within, say, 8 hours (two of those pink columns on the Workers-> Graph page) you will be able to bounce back up pretty quickly depending on how fast we find blocks. (After giving the previous statement a little thought, I don't think it will matter how fast we find blocks.) I know enough to be dangerous! LOL

I'm sure others will have a better answer for you, but that understanding works for me! ;-)


EDIT: I am in the North Carolina mountains and we are starting to get some rain and wind. Not sure if I will need to take my miners down, but I will wait and see what arrives.

Thanks....appreciate that.....so the lights started flickering, and though I hated to pull the plug...thought I'd better lean on the side of caution.  Hopefully be able to spin back up in a few hours.....

Yeah, when the lights start flickering it's best to unplug. Even if it doesn't out-right damage it, those power fluctuations can cause premature failure of the electronics down the road.

This is our 4th of BLOCK MONDAY!

This is after 3 Blocks yesterday!

That's why I run a Tripplite LC1800 on each of my miner PSUs. Cheap insurance.

one what nodes are the blocks being found (or the most found blocks/node)? are there stats about that?

I have a feeling this isn't the last block for today!!!!!!!

[bigGG]

yeah it is very likely dying on you.

and most likely it is a board or two.

not the controller.

definitely possible that the board is dying but for now it seems to be working from the local side, so i was wondering why the pool side hr hadn't moved.  but it's slowly coming up now (>10.5TH/s) so the number on the workers>>workers page of kano.is must be a little bit longer average than what i expected.

Your hash rate can take an hour or two to level out.
Of course that can be high or low on the pool, but it takes a while to converge.

Also, of course, if you were almost continually mining, i.e. the stop+start was short, the 1hr hash rate will take longer to average out since it's not 'starting from now at zero' but instead averaging out the longer running lower hash rate with the higher new hash rate.

Hi,

I have had a very similar experience. Had a bit of a power spike and middle board on one of my s9 just stopped hashing. Sounds exactly like your board. Everything working except no hash showing in the pool and board just showing no hash, (so kind of not working, but working!).

I moved controller cables from working boards to the dud one to see if that helped...but that did  no joy  . I left it running for a couple of days but that did not help either.

Have just, (today) sent board off to Bitmain Warranty USA. I am in UK so may be in for a long wait. Still the s9 is still pushing out 8 (ish) Th/s on the two remaining boards.

I'll let you know how it goes...

Ok my friend, just got done installing the board!  They look new and work just fine although I decided to clean the miner by compressed air and now one hashing board only has 48 chips working instead of 63.  I knew I should've cleaned it!  .  If you have the link that you could give me in order to send this board for repair in the U.S, I would really appreciate it!  But yeah the control boards work just fine, I even tried and installed 2 new boards on the miner just to make sure that it wasn't a faulty control board and that it really was the hashing board that messed up.

So you're good to go!  In the U.S you should get it super quick!  Good luck my friend!

And Mine On!

If the board had faulty chips after blowing compressed air than maybe the heat sinks are sitting properly on those chips and the chips did overheat.
You might want to remove the board(s) and check the heat sinks hoping the chips were not damaged.

Thank you for the information. I'm sorry about your hash board. I am assuming you mean the repair facility in Colorado? Bitmain Warranty? If so, their website is:https://bitmainwarranty.com/

I will proceed with my order from the link you gave me.

Good luck!!

That's altcoin nonsense.  Couldn't affect this pool, and with kano-san on the case, not much ever will!! 

Mine On!

Hey guys, new and small scale miner here!

Really enjoying being part of the community and contributing my measles 1.2 THS to the pool!

Although I'm not much of a miner, I am quite a good business man - and I'm realising my single S5 is not going to be generating me much £££!! Thankfully, I have solar panels which cover a lot of the cost of electricity so it is just about economical for me to run.

I have a question - does the forum or this mining group ever do a group buy? Seems that Canaan only have bulk buy of 741's, has anyone tried to organise a pool buy? It would be a great way of boosting pool mining power!

Anyways, would be great to hear people's thoughts. Great block results these past few days!

PS - I'll take a 741 miner!
