The calculator has only one serious problem to my experience using it. It predicts silicon quality margins would be minimal for the SOC voltage needed to allow the rest of the settings to work stable. So, while most settings prediction work exactly as shown, the SOC V needs to be tested individually by anyone wanting to apply the settings shown in the app. In my case to work stable on my ram being at 3333MT/s c16, instead of 1.02-1.03V for the SOC, I needed 1,15V to make it stable with my RAM's voltage at auto being where the app suggested (1,35-1,36V). The SOC's voltage needed depends on the mem controller in the CPU and it is a silicon lottery thing. If the app suggested that it would be almost perfect.
