KanoPool since 2014 🐈 - PPLNS and Solo 0.5% fee - Worldwide - 2435 blocks

[scouse15]

I wasn't, I have been mining for months to just stratum8080.kano.is:8080 which is the setup on pool website page. I never realised the pool had geo nodes, may be an idea Kano to add geo nodes to home page at pool website.

Thanks for all the help and guidance you provide, its is really appreciated. Top man.

Well mixed results with the move to 2.0

Had to clock two back to 550Mhz and one has locked up or exploded or something, gotta wait till someone reboots it then catch it before it overheats again.

New firmware seems to run a bit hotter than the original B13 firmware.

Wish there was a way to keep the existing firmware and just copy the miner binary over. hmm.

yep

good luck on restarting
i will not bother with this "upgrayedd" again until... maybe never

heh, well its worth it if it helps find more blocks here imho I've got them running as well as they were before the upgrade now. Temps back to normal.

These are all hosted, so gotta wait till remote hands do the reboot of the problem one.

Those of you that have updated s9 to bmv2. Can you say whether or not hw errors are down? My 550 batch shows 10's of thousands of errors. I ran an s4 for 6 months straight with less than thousand errors.  These miners really are a piece of work

I have updated to V2 on all my S9s first and second batch. i do see improvements less HW error as before i was hitting very high numbers on HW errors a one week run would be 15k+ 12 days 30K+

I will check later and update this post as i should have sufficient amount of HW for 24hour run

[elokk]

Bottom line is that the s9 is a pile of crap, high HW, bad code, high failure rate of PCB, etc. Kano's stats have proved the bad performance of the s9 as well.

Luckily bitfury chips are starting to hit the streets

I've no idea what you are going on about.

As for orphans - lulz yep you've just been confirmed a conspiracy theorist who makes up shit.
The last orphan was 262 blocks ago, then one 11 blocks ago - geez what the fuck are you smoking.

Edit: go check with BlueMatt - 15 minutes before our orphan, the old relay in china stopped working.
Some time (hours) before the orphan, the fibre relay network stopped working.
There was no relay network into china working when we got that orphan - that was 2 of the 3 causes.
Then just to completely screw us over, the ckpool transfer of the block to the CN node was delayed 99seconds by the GFW.
You will find that some non-chinese sites saw (and accepted) our block first also.

... above as I've already posted.

Edit2: and it's listed here: https://blockchain.info/block-height/442979
They probably even got our block before the BWPool block
You can't have an invalid block as an orphan.
There's (still) no segshit code running in the ckpool version I'm using to generate work.
Only the nodes have been updated (OS and bitcoin) and they don't generate work.
I'm still running the ckpool version from back in august before the segwit code was added there by a core developer and was then changed and untested and broken.

I updated 3 S9's--a B2, B5 and B9.  They are now (after 48 hrs) showing .0039%, .0006%, and .009%.  Comparing number of HW errors is pretty meaningless because it depends on how long the miner has been hashing--to say nothing about how the number of errors in a given time depends on the hash rate--so comparison of number of errors between an S9 and an S4 ought to be adjusted to reflect the different hash rates, even when run for equal times.  The error percentages I am seeing are quite good I think and comparable to those I got with S3's, S5's, S7's and SP20's.  There was a slight improvement with the upgrade to v2.0 but what I notice most is less fan speed hunting, more consistent chip temps (around 90 degrees F) which are well within spec for the chips.  Yes, these miners will get failed boards--one of my S9 B2 boards was just sent for repair (the failure occurred before the upgrade).  That said,  I really like my A721's as well.

Well I'll add regarding HW errors.

As long as the miner isn't failing due to overheating/pushing it too hard/whatever, what you actually want to compare is the accepted hash rate.
The Workers->Shifts statistics and Workers->Shift Graph will show that.
HW errors, stales, etc don't count in what you get rewarded.
Your rewarded hash rate is purely just accepted valid shares.
If that goes down (or up) after a few days then you'll know if it was better or worse due to the update.
Though, finding a block is certainly gonna reward better than not finding one

[gt_addict]

Did a restart happen? as my S9 failover kicked in for quite a while.

Not that I can tell on my equipment...everything looks normal.

I always thought that you want your err rate at or below .01%, otherwise your are wasting power for no increase in hash rate. Especially when you are OC'ing the miner. So better to have .0005 err and 4.8 Th then .05 err and 4.95 TH. Is that a true statement?

[gt_addict]

R4's are available on Bitmain. Get them while they last: https://shop.bitmain.com/main.htm?lang=en

I'd love to have one, but can't afford it at the moment, I'm trying to only use the Coin I earned and was going to pick up a S7 @ 2.7 TH but we hit that dry spell and I did not reach my goal until after the S7s were gone.

I get some free 110v electric at work, so the cheap S7s with the PSU that runs on 110v is a no brainer, I'm hoping to ramp up to buy some R4s down the road.

Does anyone know of any other place to pick up Antminers that accepts BTC?

www.eastshore.xyz. HagssFinn has bought three miners from them without any issues. I have been in contact with them regarding an S9 but ended up getting one from a member on here instead.

Block by dance191!  This is his 23rd Kano block and our 2nd of the day! 

[rammendo]

Sorry, what does "NYA" mean? I missed it. Google doesn't help me. It showed as "New Zealand"

[ZACHM]

It is another node to connect to, located in New York.

On to a lighter subject
I guess few noticed, but no one asked, about the thread title.
Well I added another node the other day that can be mined to.
nya.kano.is

... oh and also ... it's in NY (New York)
If you are between the link between NY and Vegas it wont really help.
If you connect to NY and it's WAY faster than to Vegas then it may reduce your stales.

If you're planing on doing any serious expansion, don't get R4s. The per/board & per/chip cost vs a "regular" S9 is taxing on your ROI.  

[ZACHM]

Yeah, use standard computer PSU's, not the Bitmain ones.

[ComputerGenie]

Yeah, but Bitmain says "The APW5 is compatible with one Antminer S9 but ONLY with a 220V input. With a 110V input, we do NOT recommend that APW5 be used to run an Antminer S9." And all I have access to is 110V.

I agree s9's would be ideal, do you have a way around this?

Yeah, use standard computer PSU's, not the Bitmain ones.

Yes, that.  
One example: https://bitcointalk.org/index.php?topic=1308296.0 *


edit:*specifically the breakout boards, not those exact PSUs

[ZACHM]

I don't think those will work for him, they are all 220V. At least I hope so, you don't want to be pulling 2800+ watts on 110V circuit.

This is getting really far off-topic. If you want to discuss further it should be elsewhere.  Before kano yells at us.

edit: I see your edit now.
