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.

Nobody is complaining. Tongue

. Tomorrow I'm getting the replacement control board for my S9, it is already in the local DHL office! Grin

Very cool! I know that feeling of getting a replacement that makes "things" right again! Cheesy

I NEED a control board for one of my early batch S9's. It is the two-piece type and I believe it is the Beagle bone Black board that has failed. (It has some melted plastic on the back of the card that makes me think that is the culprit.)

I did swap it out with another S9 controller and that seems to be the problem. So I have one S9 totally off-line. It will only have two working hash boards when I get it back on-line. I'll worry about a board repair/replacement later.

My MAIN question is:: Where did you get the board from???

I have just in the last hour put in a ticket with Bitmain and Bitmain Warranty looking to get a repair or replacement for the board. Neither of these companies list it as being in stock. Guess I'll just have to wait and see.

Best wishes..... And of course,

Can't complain at all about the weekend block count. Five blocks in two days is still pretty sweet!

I look back fondly to those seven-block (or more) days. We were then at ~32-34PH. That seemed like a lot for a small, lucky pool like us! Of course, BTC price was way below $800 then. Cool

But I feel that as our pool continues to grow, we will get back to those 7-block days!! Grin

We have more than doubled our hash rate in the last year and I wouldn't be surprised if we start moving towards 100PH by the end of this year. Sure, the block reward will also decrease with paying out more miners, but we will even that out with more frequent blocks!

So, hang on boys and girls, we are moving into uncharted territory with increasing pool hash and an amazing run in BTC coin price. If the price drops it's a chance to buy. If it drops substantially, perhaps some will turn their miners off and give us a difficulty decrease. (I wouldn't hold my breath on that, however.)

Best of luck to us all!! We are in this together!! Cheesy

Quote from: matscol on September 10, 2017, 10:20:23 PM

The pool-side hash rate for one of my S9's dropped today to about 2/3 of expected. Looked like a bad board, and indeed in local status when I checked it was showing 0 in the GH/s(RT) column for one of the boards (though under ASIC i've still got all o's).

I powered it down, cleaned it out, restarted and now the local status shows ~4,500 in the GH/s(RT) column for all 3 boards. But the poolside hashrate is still showing ~9.5TH/s for that unit.

Has anyone had something like this happen before? Any advice?

I certainly don't want anyone to leave the pool but at what point does it make sense for someone to solo mine?
...

Solo mining for a small miner (less than 10PH) is high risk gambling.
The smaller the hash rate, the even higher the risk becomes, though of course the possible loss reduces also.

10PH currently averages about 4.5 days per block.
But if you e.g. hit a 300% block (which is expected average 1 in ~20 blocks you'll find) that would be about 2 weeks between your solo payouts ... with 10PH

If instead you only had 1PH, a 300% block becomes well over 20 weeks - since difficulty is expected to rise over that time frame and thus 300% gets harder and harder as that 20 weeks progresses.

Bottom line is, if you are a gambling addict, risking a large amount for a possible big OR small OR zero reward, then solo is for you

Otherwise, stick with the intelligent choice, and mine here

Oh I agree 100%. I am not even considering it. I was mainly referring to those like Cobra who is close to 20 PH. While I have the resources to set up a 20 PH mine I don't have the balls to do it. I will stay a small fish and stay in the pool I was just curious about those with serious hash power where the crossover point was.

Yeah I can sink 150k which is about 120 Avalon 741s.

If I did this I would be at 900 th.

Since I have another 70 th I would be very close to 1ph

The network is about 7500 ph. So I would have 1/8000 of the network.

Back in 2012 I had 10gh. The net work was 21th.

That is 10000/21000000

Or 1/2100 of the network was all mine.

Wow hard to believe that 22 gpus in my garage in NJ USA in 2012 was 1/2100 of the entire network.

I used about 11000 watts to mine then

I wish I had that now say 4 ph using only 11000 watts

I will never have enough CPU power to even remotely consider it but if you look at the last 15 blocks we found Cobra found 5 of them and Block mines found 4. They have very impressive hash power but I wonder if having those block rewards all to yourself would be more in the end than sharing it with the pool. On average it seems like each of them find one at least once a week.

Their ratio doesn't represent the same as if they were solo mining. It is the total hash rate of the pool that contributes to the 'luck' the pool has and the average frequency of blocks. Or that is my understanding. Yes, they could solo mine, but then their 'luck' we be the same as a 'pool' that had their combined hash rate. So they might get a block a month or something like that. With the pool, because it is higher hash and more blocks they probably make more than if they were to test their luck solo.

Wrong 10 ph should make the same blocks solo as in a pool.

Variance is a mofo. A pair of 95 percent cdf is 1 in 400 but. If you solo mine. That is crushing.

Solo vs. Pool mining: your expectation is the same, your variance is not. It's higher for solo.

It only makes sense if you really don't need the BTC...seriously, the amount of hash needed to find that many blocks consistently is not what most of us can afford to "front." The investment, and overhead, is huge. We mine to pools because the end result is far better for our long run, which is to accumulate BTC at a consistent rate for future security. I have solo mined. I have found more than one block doing so...but that was back "in the day" when you mined with a laptop CPU. Just before I switched my pool over to Kano some months ago, I put my hash on cksolo for six seeks just on GP...and, of course, came up empty. If mining is a hobby (and, if you pay for power, it could be an expensive one), then go solo.

Also is pool's hashrate is increasing. Now at 84P

I sense another block in 12 minutes... Roll Eyes

or not..

Magical thinking bro.

I remember this 55 years ago and me and my older brother helped
