Thanks again pekatete !!! How hard are you pushing your S3? I have a server room that I can use with A/C! With two power supplies for each miner AX860 ATX Power Supply — 860 Watt.
Is anyone running the newest firmware from Bitman ? I keep playing around with Voltage and Frequency settings but my hash rate spikes to over 500 for a couple of hours but then drops below 400 ?? why ?? my temps are 38 to 40 ?? I also cant edit my /usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua (Permission denied ) file for frequencies higher than 250 ? Any Ideas ?
