What is the recommended setup for antminer S4.
I readed on dogie review a issue with firmware and vardiff.

Update to newer firmware from Bitmain site should give you Cgminer 4.8 and fix some of the problems you read about.
I don’t set anything on this pool diff wise, I let it rip; I have 2 S4s undercooked 1700GH each. Just depends on your electricity rate.  Check the S4 Support thread Page 120 I think has the voltage vrs efficiency graph.

Same here. The pool starts everything at 1-and-a-bit-k (1024?) and adjusts from there. I do set my S3s at 256 and let it adjust them up, which the pool does automatically.
By the way, if you are like me and love touching everything, there are tons more fun things to mess with than difficulty. It is over rated for us new miners This pool handles it perfectly imo and even my 256 is a waste causing more traffic than what is needed. At least in my experience the only time to really change difficulty is with a miner which has a bug, IE what you read about the older S4 firmware. I am running the January S4 firmware on my S4's. I think Bitmain did some voltage tweaking to it like they did with the S3 Jan firmware, but I do not have proof of it with the S4.

Best pool ever!

Does this pool provide a better hash rate compared to other pools? I have only been mining here for about 1 hr and seems more stable and a bit higher.

All my workers from 100GH to 1.55 TH show within 10GH of what the miner UI shows damn near constantly which I guess means the Auto Diff is spot on.

That version may have some issues, you should upgrade to the Jan 29th version available from this page.

I haven't had any drops outs?  Been mining CKPool solid the past 24 hrs

Ok, thanks for the info.
As it is also not a local problem (failover to backup pool -which is in Europe- was working and mining), it must have been a connectivity issue somewhere between my local provider and Kanos CKPool provider... stuffed transatlantic links, congestion at any2 IX in LAX, whatever.

Gotcha... I just started mining Kano. 
Who are you using for your backup pool?

My criteria for a dust collector (backup pool):

- PPS
- extremly reliable in terms of availability (and payout)
- different continent and network provider than main pool
- not one of the big pools

so currently it is the european stratum sever of emc (I know, belongs to BFL for some time now, which I don't really like... but hey, as a dust collector..altough the min payout is 0.02 btc, so it takes some time to get my collected dust, but I'm always getting it.. so far at least).
And if everything goes south, I have nicehash as the last resort...

Currently I am thinking of changing my backup pool (because of the 0.02 min payout and the uncertain future of BFL), but have not yet decided...

I use CKpool....I like playing the lottery when Kano's pool is down. 

[BrokenArrow]

I appreciate the info...


I just started mining a few weeks ago, and started with westhash and BAN, so I'm currently using them as my backup pools.  I just started with Kano yesterday, so I'm still waiting to see if the rewards and payouts will be better?  This is all new to me so I'm still testing different pools. 

I just checked out the ckPool, and looks like a fun option....

...
I'm not sure what the confusion is, but there was no pool outage.
As it says, uptime is 14hrs.
As I said, it was a ckdb restart.
The pool is made up of 2 parts:
1) ckpool that you mine to that handles all of that on the mining side
2) ckdb that gets all the data and deals with it on the data storage and web side.
An outage of 1) affects the miner.
An outage of 2) doesn't.
Great idea that hey

Hi Kano, when ckdb is down, does ckpool keep data in memory until ckdb comes back up and then send all kept data for ckdb to persist?  Or does it keep it in a file and you have to manually transfer data to ckdb?

Not that it's important, I was just wondering.  

Firstly, ckdb is a memory resident DB.
The postgresql backend is simply the permanent storage that is only read on a restart and written to with all the permanent data.

ckpool logs all it's data to hourly logfiles (about 1-1.5GB each at the moment) as well as sending it to ckdb.

A ckdb restart reloads the permanent storage DB, then using the info there, it goes and reloads the log files from where the DB was up to.
It can currently reload the log files about 50 times faster than they fill up, so a 1hr log file often takes less than a minute.
It obviously only needs to look in the last 1 or 2 log files since the down time is always very short
It is sometimes 2 logfiles since it may happen just around the time of the log file change over.

At the same time, it has been getting all the new incoming data from ckpool queued up.
When it hits a match in the log file vs the 1st incoming queued message from ckpool, it knows it has all the data it needs from the log files.

At this point everything is back to working - but out of sync.
It then has to sync/catch up on all the data queued in ram, that was transferred from ckpool while ckdb was reloading the log files.
That sync number is the number it shows on the bottom left of the web site
That number also grows whenever ckdb gets behind processing the data from ckpool, usually due to DB write delays.

Currently the reload takes from 3 to 5 minutes and the sync usually only takes a minute or two after that to get back down to zero.

I didn't have the chance to thank you for taking the time to explain various technical aspects of your system.  I'm particularly interested on those aspects, being myself a software developer trying to find the time to invest my knowledge in the Bitcoin world.  I think 24 hours in a day is not enough.  Too many things I want to touch and do.  Well in the meantime, my miners are working for me.  Thanks again Kano!
