Try setting the offset to 0.07, then boot into windows and stress test again.
I think I've sorted it now
I've got it set to 0.012 with max voltage of 1.2529 I would have liked to have got it to 1.240 but not sure what I'd need to set it to
I'm really confused by this
In HWMonitor which value should I be looking at for CPU Voltage, is it the VID value under the CPU part because it's only the VID value that I can see that matches the voltage I've set in the bios (1.240) nothing else matches it and in manual mode it still won't drop down when idle
