ASUS Sabertooth P67 Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASUS Sabertooth P67 has eight phases for the CPU main voltage (Vcc a.k.a. Vcore) and two for the CPU VTT voltage (integrated memory controller and L3 memory cache). Therefore, it uses a “8+2” configuration, using a digital design.

As mentioned before, this motherboard uses military-grade components, including solid ferrite-core coils, which present less energy loss than iron-core coils (i.e., they improve efficiency), solid capacitors, and low RDS(on) transistors (i.e., higher efficiency).
