I recently upgraded my s3's firmware what is with the new voltage setting underneath the freq setting? I run mine at 250mhz and have been doing so for 3mos now without a issue. What can this new voltage setting do can it give me more speed? I rn the on Corsair HX1000 PSU's So i got watts to spare

same questions here https://bitcointalk.org/index.php?topic=771979.msg9608517#msg9608517
but other direction...
it seems the voltage changes are not really applying at least downwards...
i answered the voltage question on the previous page of this thread
You should have noticed by now that your response contains a fundamental error, no wonder people have not taken notice of it! aka

To add the frequency you will add this to /etc/config/asic-freq
The S3 frequencies are not set via the asic-freq file (at least for the latter firmware), rather via the file /usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua (see instructions here: https://bitcointalk.org/index.php?topic=699064.msg8370071#msg8370071 )
