Makes perfect sense. If the problems were as bad as certain people has made it seem like. I would have had issues somewhere. With out a doubt on how some people are making it out to be the end of the world. I would have had a problem. Yet nope.

It not good for the pool. And the pool has had enough problems. 

With that I'm done. I wish this pool with nothing but great luck. Have fun.

What's not good for the pool? S9 reliability or lack thereof? How so?

I'm not a stats guru by any means but I can grasp the concept of sample size. Your 19 miners - a drop in the bucket. Consider yourself lucky. That doesn't make everyone else wrong though.

It is irresponsible to make comments on an object if they have no experience with that object. It is bad for the pool because most people will see through the shit and leave. Just like the fanboy comments about Linux and against windows. (Not saying you mentioned anything about that)
 It's not needed. It pushes people away. And last time I checked. This pool needs all the hash it can get.

P.S. There is no such thing as luck.

I have never made any false claims or claims of an object I have never used or owned.

You're missing the point. I don't need to know if you own any S9s because that's irrelevant. You seem to be drawing fundamentally wrong conclusions about the reliability of the S9 and it would still be wrong whether you post a screenshot, or a selfie, or whatever. But even that's not your most ridiculous claim. That honor goes to your insistence that nobody else can dispute it. Because random reasons.

I don't own a lot of things yet I don't think that disqualifies me from having strong opinions about them.

For example I don't own kano pool but I visit the thread anyway because (among other things) the guy who does actually own it also knows a thing or two about mining and is not shy of sharing it.

I also don't own Antpool but I don't like it because (among other things) their 0% fee is misleading and they take much more via tx fees.

That is my opinion. And I'm not gonna post a screenshot to make it look worth more than it is. If someone thinks my opinion is shit I welcome an argument on facts, not on some made up ownership criteria.

Your comparison is flawed because most likey. You have mined on both there by giving you sufficient data to form a opinion and put it to words.

Now I will concede that owning a mining device might provide useful data to form an opinion about certain aspects of said device. Except in your case where you extrapolate your alleged 100% reliability in a way that makes no sense whatsoever.

...

Um, you're the one who said 10% failure was OK, coz something about trucks and cars and fork lifts

I doubt there are many here who agree with that ...

However, there's another obvious point about your comment here ... sample.

Indeed if someone only has 1 miner and it fails (I only had 1 S5 and half of it failed) then it's not reasonable to assume that all S5s will fail in the same way.
But, there's the opposite that is also true, if someone with a small sample has no failures does that mean no one will ever have failures?
Guess what the answer is ... ... ... 'no' ... and even you were saying how 10% was ok

People have problems with their S9 miners - it's in lots of posts on the forum.
How bad are those failures? I've no idea.
Even someone with 20 really has no basis to extrapolate their reliability.

How bad are those problems for those who have them?
Well that's each individuals decision, coz no matter what you say, you cannot say what problems anyone else WILL have.
The bitcoin network is around 2,275PHs
It's not unreasonable to assume 15% of that is S9 - so probably about 160,000 of them.
Yeah even 20 says next to nothing about 160,000 of them

The people that do not agree with my 10% comment have then obviously never been around actual machines or large equipment.
10% has only been mentioned today. Before that. For the last few months. The way people have been talking. It makes it seem like the failure rate is way higher. Like that's all they do. (Break down) If you have some actual failure rates from bitmain themselves. That would be great.
While my sample size is small. I have bought from many batches. And the way people have been making the "failure rate" seem. I would of found one.

And a lot of people here are acting like none of the failure rate can be attributed to people scerwing them up on their own. And then claiming the fault was not their own. And again. I am not pointing fingers here in this thread. You are basing your asumpitions of the failure rate from other threads of people you do not know. With no actual proof that it wasn't them who screwed the pooch.

Actually there is.
It's a measure of your past results vs other's past results (or expected past results of a known system)

Kinda like 5 finds out of 6.5 expected blocks doesn't make you any sort of authority on the future expectations of A7s as a whole, but you got all douchey about that...

The future expectations of all miners is long term 100% luck.

When the larger sample results don't match that by a large margin, then there is MOST likely something wrong with the miners in question.

This is called SIMPLE statistics - nothing even slightly complicated about it.

[tournamentdan]

Heck. I don't even like Bitmain that much. I really don't care about what happens to the company. I only use the miners because they make the most money. As soon as bitfury gets their heads out of their ass's. I'll buy from them. If the A7 was any where close to being comparable.  I would buy from them. I only care about making the most amount of money so I can continue to grow my mining business.

Yep that's pretty reasonable

My stats posts, which are supposed to have nothing to do with that , are about the fact that a particular firmware, S9v1 has REALLY bad luck on the pool.
To the point where it is unlikely to just be "bad luck"

The S9v2 so far has been good (above expected luck), but like the A7, not a lot of data yet.

Yeah, I can only go by your numbers on the s9v1. If you say so on that. I can only agree.

Yes but V2 firmware comes with it's own set of problems - at least in my experience and from what I've read with some others.

I've got 22 x s9's.  I had zero issues with any up until first batch about 4 months into mining one board started producing xxxx's
Not a huge issue as scripts I've written would just reboot when this occurred and it would be good for random 15min - 15hours.
I had a couple others at same time start acting up in other units, but a downclock to 525 kept them solid.

I decided to try the autotune on a couple units.  This one with the intermittent hashboard was one of two I tested.
It seemed to fix it.  Or at least it showed as hashing away correctly as did the other unit.  Other unit I updated was one that had to run 525.
Well autotune did help on this one and propped it up close to full hashrate without chips dropping.  So thinking all was well I started to update more.

That's when i started getting a headache of issues.  I updated 6 more units and seemed all good until about 24-48 hours into mining I had 4 units just stop hashing.
I could reach them via IP but they simply stopped hashing.  I'd reboot them wait 40+ minutes and they'd eventually come back to the GUI and just sit there - not hashing.
I reflashed old firmware on these 4 - same result just didn't take as long before going back to GUI with no mining.  Somehow the firmware was locking up in the PIC phase cycle and would just hang.
I then did remote reflash of firmware and still nothing.  I ended up having to travel to the remote site and pull the 4 units.  A hardware firmware reset on 2 of the controllers brought 2 of them back to life.
The other 2 would not recognize any blades until I removed everything from the chassis and re-seated everything and flashed them multiple times with the older firmware and I eventually got them to come back.
As soon as I left - 12 hours later one dropped again.  This time was not able to resurrect it - and deduced the controller has gone bunk.  So I've taken the three hash boards and piggy backed them into 3 working units for now until I can get a replacement control board.  Since then I also learned that while the one unit with intermittent hashboard wasn't really hashing away at full speed.  Pool side indicated that the board would drop, but gui hashrate never would fully reflect it.  So I've since reflashed that back to old firmware so that my script could see the dropped board and powercycle as needed to get the most out of it.

As for other bitmain products - I had 4 boards go bad with 50+ s7's, and the early firmware releases were not good as major lockups would occur requiring power cycle and some dropped chips on the boards needing reboots.  With the latest firmware though all the S7's I have almost never need a physical reboot nor drop chips.  S4's I had never had anything but reboots needed - and fan replacements, they seemed to burn through the fans.  S3 +'s nothing more than a random reboot from time to time.

Overall I think I would have been better off leaving most of the s9's on firmware v1.
Not sure if it makes a load of difference, but I have 3 or 4 different version of controller boards in these things.
Perhaps some boards do better with the v2 firmware and others don't.  Not really certain.

I have had a similar issue with a couple.  On the BM gui everything looks ok. But on kano you could tell there was definitely a problem. Updating the firmware has worked fine for me. With no problems since.
Now before everybody jumps down my throat. To me. Updating firmware is not a real problem. Just routine maintenance. All of my miners are on the latest fw.
Hopefully you get them all running again soon.

Does bitmain know about the bad luck of the S9v1 on this pool? I don't need it but I can certainly understand why some people need the manual frequency. I'm not saying it would ever happen but if enough people complained.(with the bad luck numbers) Maybe they would release a fw v2 with manual frequency.

Well I've told a BitmainWarranty guy who lives in the #ckpool IRC channel - he sees me regularly say the bad luck figures for quite a while
However, in the past any contact with BitmainWarranty has often not got to Bitmain in China or China just ignores it ...
I have on a few rare occasions spoken to someone in Bitmain China but I'm not fond of them and no doubt they feel the same way about me

Interesting comment today ... someone with over 100 S9 (something like 120 I think) said he gets 8 repaired ... each month ...

I asked the BitmainWarranty guy how many they repair each week.
Apparently he couldn't answer that

Interesting.
Are they over clocked?
Are they exausting the heat properly?
Is this at a place that hosts?
Or in their basement?
Any power surges?
Are they using two psu on one miner?
If so are they connecting them properly?
