Hi E,

Your table only shows clock speeds. In the advanced Mode there are:

clock speed (Mhz)
core voltage (mV)
spi speed (Kbps)

I am quite a noob when it comes to hardware, could you explain how you set the other 2 variables for the test results you provided and how voltage and spi could affect results? I am reluctant to try without understanding and afraid to brick my miner obviously.

I have a 5 and a 3 module CCD. Heat is much less of an issue with the 3 module version btw. I can run the 3 module stable in turbo ultra with acceptable HW errors if ambient temp is <20 C. The 5 module only runs Turbo Light fine or Moderate if ambient temp is <20 C.
