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

Im getting low hash on this pool while on ant pool i was getting fine. Is this a problem with my miner or pool.

Your shift data shows your S7 dropping 30% at one point - so I'd guess something is up with your miner.

could this be why i only get 2.9 th/s to 3.3 th/s. but while on antpool i get 4.5 th/s ?

No, you were getting 4.7 to 4.9 until the "8axpj mutsumi" shift where it dropped 30%.
Again, check your miner.

any guess of what it could be with the miner?

Hey Kano, I asked this before, and please don't take this as a criticism of your pool or anything, but I noticed this block was only 88kb and 12.7 BTC total.  Now, I'm aware this block came only seconds after the previous block, but still there are ~97k unconfirmed transactions, and other blocks recently found (i.e. 464944) seconds after another block were still able to include a full block's worth of transactions and earn ~1.5 btc in fees (at current prices a $2000 difference!)

Is there something preventing blocks found shortly after other blocks from including the standard amount of transactions - even when those transactions are unconfirmed and waiting?

I don't know enough about this to know if there is perhaps a good reason for this, or if this is just an oversight in the code somewhere.

Thanks

a fault or a restart needed or overheat or ... ... ... ...

[Jigor]

ill just reboot it.i dont think it over heated bc its very cool in my basement.

[oawan]

Thanks for answering that.

It very well could of even been an interruption in your internet connection at some point affecting your n range average. for your hash rate in the last 60 some hours.     IF you go the the page that shows your shift graph you will prob see a dip some place in the pink zone that would prob correspond to when your hash rate dropped and bringing down your average for the last almost 60 hours.

I had my internet drop out on me in the middle of the night Wednesday for about 3 hours before I noticed my router needed to be restarted. that dropped my n range down from around 40.75THs to about 40.19  and I still have about 30 more hours to go before that drop in hash rate stops affecting my last 60 hours n average.

yea there was a storm last night and my internet connection isnt the best. ill restart my miner and router.

It's clearly the miner, not a temporary outage or anything like that.

The page to look at is not the graph, but the Workers->Shifts page.
That shows your average hash rate for each shift, which is in no way affected by the shifts before or after it.

Your hash rate was low for your first shift coz you started in the middle of the shift.
The next 9 full shifts you were 4.7 to 4.9THs

Then it dropped to 3.33 and has stayed between 3.1 and 3.5 for the rest (12 shifts so far) - i.e. something went wrong with it (as I said) during shift "8axpj mutsumi"
That's what the numbers mean - the shift also tells you when it started (UTC) and how long it was, so you can tell when it happened.

Hi Kano,

I am going to set up some hash rates in Malaysia. Should I connect to your Singapore node, if I recall correctly, for better connectivity?

Am mining here @kano.is with tiny hash rate for the past 375 days, connected to SG node and use the main stratum.kano.is as 2nd pool setting as mentioned by Carl  

i recorded <edit> ONLY 8 times fail over to other pool  

[Jigor]

Could you also explain what 5nd is. I've read about it under the payment section and saw that it will take 2 days and 11 hours to reach it. Many people told me that your first payments will be low but after you reach 5nd they will be better. Is this true? Rn my payout from the last block is .000267.

Ill reboot the miner and make sure it has the lastest firmware. thanks

Should i try updating the firmware and rebooting the miner?

4.7ths, is that a S7?  1 of the mining board is not working, when its hash, the mining board red color LED should lit up

[Jigor]

yesterday they were all lit up and working fine. once i get out of school ill head over and check out whats wrong. could be power?

may be, if u use 2 PSU to power the S7

or one board is dead

[Jigor]

yep i use two 1000w psu. any way to fix this?

I do have a corsair ax1500i titanium psu on the way but i also have another s7 to0.
ill have to stick with these 2 1000w power supplies

Sorry for the OT
Two 1,000 watt PSU's should be plenty for an S7. I'm assuming you have two boards (6 connectors) being powered by one PSU and the other PSU powering one board (3 connectors) and the controller? Don't mix power supplies on a single board. That could kill it.

EDIT: One of your PSU's might also be providing less power than specified.

[Jigor]

Yea i hooked up 1 psu to two boards and the other to 1 board and the 1 connector up front. Ill try switching the power supplies and conecting them to differernt boards.

Look in your config page for the miner and see if the card thats not hashing to see if its even the same card that's hooked to the one power supply.  Chances are esp if its a 1000w power supply and if the same one running the main board should mean its still putting out 12 volts if its powering the mainboard still. So still a high chance its not a dead power supply and a restart might just be all thats needed.  If not then try swapping the power plugs from the one hash board to another.  and also when you got the plugs off look for any signs of discoloration in the spots the plugs plug into on the board for signs of burning from high resistance esp if your plugs happen to be the kind with only 2 wires going to each plug.  Sometimes them female pins on them pci-e connectors can corrode or can sometimes just lose and not making good contact and can cause you to lose power in the plug or can build up resistance and start burning the plugs or melting the wires.    and on other spot to look at if haveing a power problem and you can verify the power supply is putting out the right voltage is to also check all the wires connections that go to the power supply esp if you also happen to have one of them ones with the breakout boards on it.

rebooted and changed power plugs. it runs at 4.7-5.0 th/s for like 5 mins than starts to drop opp slowly like .30 th/s till its at 3.5? whats going on

im going to try hooking up a different power supply in its place

also gg new block!

I kept my S7 slightly underclocked all the time I ran it, and it seemed to run fine that way.  Have you tried a dropping the frequency a bit and see if that helps?

EDIT - Drop it like 10-20% and if it stays stable then you can start inching it back up until you see trouble.  Good luck!
