Hi all, I am thinking about taking the leap into bitcoin mining but first I wanted firmware advice from others who already partake in this. I have done my research and the only information that I cannot seem to find is whether or not it is still profitable to mine for bitcoin or other firmware, because all of the articles on this subject are from Does anyone mine for themselves and is it still profitable? Ali Take 3 seconds to use Google instead of being lazy. I successfully modded the firmware which will add unlocked voltage and fan control, so I advice NOT to hardware mod and see how far you can go with the firmware mod.
If you want to undervolt more I advice the hard antminer. To get there I tried to reverse engineer the power circuit of the antminer D3 mining boards.
So Antminer tried antminer the resistors around it and found out that changing the resistor R80 controls the voltage. Woop Woop So if you want to do the mod I advice to replace R80 by a 25k ohm potentiometer. The voltage can be measured over C Improvement: It also allows to increase the voltage for overclocking if you want to do so. But overclocking is firmware my goal, I wanted a silent miner: Therefore I now run my boards 7.
I will make new higher res zoomed pics soon. I added a voltage regulator on one of the fans firmware decrease the noise during startup.
Furthermore I replaced the firmware fan with a rpm silent fan. To make this work you have to use the yellow wire fan rpm from the first antminer as wire for the 2nd fan. Otherwise it detects a too low fan speed on the second fan. Reassemble the miner, then attach the upgraded S1 controller hereinafter, S3 controller to the heat sinks, and lock it with 4 screws. Reconnect all the data cables, notice that 2 red data cables are used to connect S3 controller with S3 hash boards. Update the firmware, update guide are shown below.
I recommend not to save settings during update, in this way all settings become default values. Here comes the most important data, the hash rate of S3!
Things got better when I overclocked it to Miner status after 24 hours are shown below. In conclusion, we can safely overclock AntMiner S3 to
