Add 2 voltmeters for Vnb and Vddr monitoring. 125mW resistor is the Vnb mod: start at 1.76V and modify into the bios. Short black wire is the Vddr mod: disabled for TCCD for this time. Next time introduce the jumpers for enable/disable of this mods.

Add 1 voltmeter for Vcpu monitoring. Desold Vcore mod at this time because not working with s478 to s479 adapter. I have not made Vdroop mod because i have a negative Vdroop after mosfet mod.
