One thing is clear, my set up is not stable enough to get absolute numbers from, but I believe that they are representitive. Once I have got a bit more data I will attack it and try and remove some of these variables mathamatically. It will still only be correct-ish, but we might than have a better idea of what is happening.

Some more data, as usual here, the relevant file is "power_calc.xls"

I have measured power at stock CPU speed but varied the voltages. It looks linear enough but as you observed Les, V^2 looks a bit iffy. Secondary paths and changing Rs rearing their ugly heads perhaps.


I am going back to try and get some more MBM Voltage readings to see how they work relative to nominal voltages.

Cheers
