Re: 2 AVA4.1s Won! [4400 TH] CKPool (kano.is) from the cgminer devs [0.9% PPLNS]
What is the recommended setup for antminer S4.
I readed on dogie review a issue with firmware and vardiff.
miners have :
Hardware Version 3.4.3.0
Kernel Version Linux 3.8.13 #12 SMP Mon Sep 29 11:13:50 CST 2014
File System Version Fri Oct 3 18:17:17 CST 2014
Cgminer Version 4.6.1

Update to newer firmware from Bitmain site should give you Cgminer 4.8 and fix some of the problems you read about.
I dont 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!
