Hello... Im a new miner to ckpool. Jumped over from Antpool.
At this moment ive moved over 130-140T/H with another 200T/H coming in the next 10 days or so.
I have 2 accounts at kano.is mainly because they are shared with different partners.
On one account ive set the BTC wallet address and its fine, ive been receiving payouts. On the next account, when i attempt to set this same BTC wallet address, it says Error : BTC address unavailable.
But this very same wallet receives payouts from kano.is under a different account.
Is there a reason for this? Can i set 2 - 3 different mining accounts to pay to the same wallet?
Thank you!

Does anyone have any idea what is happening to Antpool? A lot of my machines are dropping off their stats page however machine side seem to be fine and hashing.. Lost almost 50% of my total hashing power and a few of us in the same area are facing the same.. What's happening Antpool!?   |

Yes! Ok, let me get to that this afternoon after lunch and make some magic happen... 😆😆😆
Thanks again for the help!
Much appreciated!

Ah!!!!! Ok it makes sense now!
Ok yes I will do that.
So basically once it gets unplugged, it will get dropped from the list instanteously?
Thanks!

Hello phillipma1957,
Thanks for the help first and foremost!
Yes, I could unplug the Ethernet cable and I would know which miner it's connected to.
I can also check my DHCP server on my router to see the IP's of all 48 miners.
I can then proceed to connect by using the IP's provided by the DHCP list.
However... Once I connect to the miner, I don't know which one it is on the shelf.
So I want to reboot the miner, but I can't identify which one it is on the shelf unless once I logged in... I can have it blink the led infront perhaps?
Thanks again

I'm feeling Abit sheepish typing this out..  Sometime late last week, I was feeling desperate for hashing power.. Felt kinda depressing looking at the 70 x S5's I had on the floor just sitting there and not hashing which I didn't have the time to put together. So... In a big haste, my wife and I put together 48 of them in a big hurry. Connected them all to the router and DHCP assigned an IP. Basically powered them up 8 - 10 at a time and configured them. Now I've got 48 S5's on DHCP but I don't know which is which. Now that some are showing visible problems on pool side, I would like to power off and reboot it but I don't know which machine is which worker and which IP.... Is there a way to connect to the machine and have it FLASH or BLINK the front light so I can proceed to map out which machine is where without turning them all off and starting 1 by 1 and setting the IP's..... Thanks a big heap in advance for the help! |

The luck on Antpool seems terribly terribly poor! Amazingly poor. Perhaps its time to hop pools again or maybe someone is delibrately causing this to happen.... |

Hello all!
Thanks once again for all the help. Loving the community spirit! Apologies for my slow response too as am away in Bangkok until Tuesday.
We are based in Kuala Lumpur, Malaysia. Daytime temperatures average 36 deg celcius to 38 deg and the occasional 40.
Wires are now normal. Warmth due to heat from other miner's blowing directly on them.
Still rebooting and the damed red light. When i check the temperatures, it shows 78 deg - 79 deg - 80 deg.
Im thinking this is where thermal shutdown occurs. I powered up 5 S4+ initially and they went on and on for a month without a hassle. Thats why im led to believe the machine is good and solid and its something to do with the heat in the room.
We are now looking at ventilation options. As the room is a long narrow room, ventilation specialists are suggesting that perhaps we work on "changing" the air in the room every 10 seconds.
Meaning something either PULLS out or PUSHES in air at the rate where the air in the room is changed entirely every 10 seconds or so.
Im thinking of the following layout.
W FAN PULLING IN COOL AIR
I COOL ZONE
N ////////////
D HOT ZONE
O \\\\\\\\\\\\
W COOL ZONE
FAN PULLING IN COOL AIR
So as we have windows every couple of feet or so, this is how i plan to array my miners.
The hot zone will have high powered industrial fans directly on top of them, lots and lots to pull out the hot air. Hot air rises?
Some feedback would be much appreciated.
At this moment, we are currently running, and have on the way
Currently running : Spondoolies SP35 x 18, Antminer S3 x 12, Antminer S4+ x 35, AsicMiner Tube x 12.
Arriving in 0days - 30 days : 100 x Antminer S5, 50 x Antminer S3, 4 x AsicMiner Tube and possibly some Avalons.
Im thinking this heat problem needs to be resolved properly or at least well thought out before the balance of the machines arrive or we'll be in for a big surprise and more machines asleep than awake.
Thanks again!

Funny you mention the S2 PSU, because I just spent a couple hours today working with a guy figuring out why his S2 kept shutting down - the PSU is getting weak. We ended up clocking it down to 187MHz before it'd stay on continuous.
I'd also worry about the gauge of power cord and the mains voltage. You're probably drawing around 8A into the PSU, which if you got a nice cheap 18AWG "10A rated" cable could get fairly toasty. You want at least 16AWG power cord, and the higher mains voltage the better - less line current will mean less line power loss, and a higher mains voltage (well, to a point) will mean the active PFC stage of the PSU works more efficiently, increasing the overall PSU performance.
Also, definitely make sure you don't have heat from adjacent shelves blasting right onto/into those miners. Make sure hot air is isolated from ambient and exhausted efficiently from the room.
Lastly, I kinda want to say I hope you get along well with the S4+ because I kinda feel sorry for anyone that bought 'em. The efficiency and hashrate are mediocre for the price, as they're built with a chip that's soon to be two generations old and they're also sorta the least efficient miner anyone's built since about last August.
The power cord may be a problem. HOWEVER..... Ironically, when i relocate the "SAME CORD, SAME MACHINE" to shelf 1, the cord is no longer hot. Its just nice and warm. No longer painful to touch. We will have a look at our own wiring installation today and see if there are any bad contact points or any mistakes. With the machines chomping in hot air from another machine.... What can we do about this? With large mining farm installations especially the ones we can google about in China, you find that inevitably there will be rows and rows of machines which means some machines are inevitably sucking in heat? Any thoughts? Thanks again sidehack for the help as always! |

Hello Bitmain, Thanks for the response! Much much appreciated. The thing is, in larger farm installations in China like ive seen on the internet. If you search large farm installations, you'll find that inevitably 1 shelf will always be blowing into the next. Its just a matter of making sure the air passes through the room fast enough for the heat to escape. Am i correct? There will always be a point where one machines exhaust heat inevitably becomes the air thats taken in by the next machine to ensure the space is efficiently used. I will check the machines with a red light shortly and see if indeed the board is getting too hot and is facing thermal shutdown. Any advice on layout or heat? A simple internet search "bitcoin mining farm large china" and if you view the images, you'll see the machines lined up row after row which means many machines are sucking in exhaust heat. Thanks again and i will be back with more info. It sounds like the heat in these shelf 2 and shelf 3 may be the cause. If you can, please to make sure adjacent shelves blasting the hot exhaust onto these other miners. Anytime you see RED LED on Antminer, that means, there is/are some kind of error. It could be many things. If it stop hashing, best thing to do is attempt to log into the web control panel, then go to the "Miner Status" tab and take a screenshot. Look for the Temperature Reading of each hash PCB. If the problem is heat related, you may see high temperature reading into 80 degrees or above. If you think it is other than the heat is causing the problem, take 5 units from shelf 1 to shelf 2 and swap the S4+ and see if the problem S4+ perform okay in shelf 1. Happy Hashing! Thanks for all the help and responses.
When i rocked up back to the "farm" this morning, i found the following results.
I think it would be great to clarify what we have running here first.
I now have continuously running :
18 x Spondoolies SP35
12 x Antminer S3
5 x Antminer S4+
12 x AsicMiner Tubes
I have successfully set up all these and run consistently and reliably with sidehack's great help. Very pleased with the results.
So from the 35 S4+, there's only 30 left to be set up.
As the power from that distribution board is already maxed out, i took power from a different power source and wired up a brand new distributor board. We are an industrial facility with approximately 6,000 amps on tap.
So with these balance 30 units of S4+, we wired up 2 shelves, each to hold 15, bringing a total of 30 units.
Point to note.
1. All power cords are same brand, same price, from the same shop. Probably manufactured from the same cords. All are standard computer cords that you would plug into a printer or home computer.
2. Each level (2 units) has its individual circuit breaker and is individually wired so no plugs are daisy chained.
3. Checking the power draw at all cords and the wiring leading to the plugs is all registering 10amps or thereabouts.
The shelf nearest to the wall (and window where some cool air comes in) has had NO issues at all. Not a single unit dropping off the grid and the cables are not warm. The cables are nice and comfortable.
The 2nd shelf, EVERY cable is warm with some others warmer. This is where some of the units are dropping off the grid.
- Could this be because this shelf is directly behind some other miners like the AsicMiner Tubes and receiving its heat?
- The cords feel really warm. Could it be the heat from the miners directly infront of it? I cant imagine it would be the case though.
I also have a 3rd shelf that is prepared for expansion and growing purposes.
I relocated 2 miners from the first shelf where the cables were comfortable and not warm to the 3rd shelf. And NOW the cables are warm and getting hot.
Somewhat confused.
Approaching the miners just now, i noticed the following.
1st shelf, all 15 units going strong and still hashing.
2nd shelf, i observed the following
1 unit has a SOLID red light. Unit is non responsive. Unplug and replug in and the unit operates normally.
3 units have NO light in the front. Front fans and rear fans are not spinning at all. HOWEVER, PSU fans are spinning. (For some reason, Antpool records these guys as still hashing and running but they obviously dont seem to be running with no heat coming out of them and the network port not showing any activity). A hard reboot by unplugging and replugging makes the unit come back up and running again.
Ironically, shelf 1 is perfectly fine.
This happens only on shelf 2 and shelf 3.
Unit from shelf 1 that is perfectly nice and cool. When you moved to shelf 3, the wire gets HOT.
Any thoughts?
Thanks alot!

Hello friends!
It seems there's a lot of info online about the S4 but not much about the S4+. Given they are almost identical except a better PSU if I'm not mistaken.
Together with a friend, we're now installing 35 of them.
A good bunch of them work well however with a few units, I'm having some issues.
1. After 30-40 minutes of hashing, the red light appears, stable and solid. No blinking.
This red light does not go away unless you unplug the machine and plug it back in. The machine will remain unresponsive and not hashing until it is power rebooted.
This happens with 2-3 machines so far and different machines at times.
2. On a few of the above machines, after the red light appears and you power reboot it, the settings in the machine has all gone back to stock. Meaning the mining pool config is now mining back go antminers account. The stock settings. I have to reconfigure it then.
3. The power cord on some units are very very warm. Scary warm. I will do some swapping around tomorrow to see if the power cords are of bad quality.
4. There is 1 last machine.
When you unplug it and re plug it in, you can connect to it.
After 20-30 seconds, machine is non responsive. Front panel does not show any lights at all and only thing lit is network port lights.
Thanks in advance for everyone's help... It's much appreciated!

Seems slush has come home! Haha |
|
|
|
Whats happening? Time to switch pools? Quite alot of miners to change over! Anyone have any thoughts? |
|
|
|
Last block found was 1 day ++... Sad and quiet day for slush's pool! Can only hope the blocks start falling down like rain after this! |

A quick question...
On the gekkoscience breakout boards, there is a small black knob. Can i understand abit more about what that knob does? Its turned all the way to the right hand side now until maximum.
Thanks again

Hello Matt! Yes, it seems the dip switches were already set correctly according to the diagram that dogie posted. Sorry for wasting time on that. It was already set correctly for 4 miners in a set. Ive reset the clock to 270mhz. Decided to get greedy yesterday and went to 300mhz. Ive also rechecked all the connections on the daisy chain wires and powered them back up and lo-and-behold, all 16 boards are now functioning! Im going to keep them at 270mhz for the moment... I did however notice this under statistics.   On one set of miners, board 6 is showing something different. What does that mean? Beyond that, it looks like these babies are ready to go. I will put together the 3rd set today. Thanks again in advance for the help and input! |

Hello all! Please accept my apologies in advance if my mistakes seem pretty noob-ish. My knowledge level is quite rudimentary at this point but im a willing and quick learner! I recently find myself the proud owner of 12 Asicminer Tubes. I've set them up according to the instructions i should be following however it seems that i may have gone wrong somewhere. Would like to seek some advice on where i couldve gone wrong. How i connected them was as follows. Power cables - i only used 1 power cable per board, hence 4 power cables per miner. I used the outer-most power port. The one on the right hand side if you are facing the fan of the machine and i used this right hand side port in every instance. I connected the miner's as follows Miner 1 - Long cable connected to Block Erupter - UART1 Miner 2 - Long cable connected to Miner 1, Board 3 port (The board on the left hand side if you are facing the miner's fan on the front) Miner 3 - Long cable connected to Miner 2, Board 3 port Miner 4 - Long cable connected to Miner 3, Board 3 port All miners have unique dip-switch identification. No duplicate if im not mistaken but i will double check this. The miner's all power up properly, and they begin hashing properly however.... Out of the 2 set's ive set up, a total of 8 miners, the results i get is as follows Set 1 : 1.6 T/H Set 2 : 2.3 T/H Clock speed at 300 (overclocked speed) When i go into test results, i get the following results.   Im given to understand that there should be 16 boards in total. Im not sure if i made a mistaken somewhere along the way. Any help would be much much appreciated! Thanks again in advance |
