ASRock Z77 Extreme4-M Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASRock Extreme4-M has four phases for the CPU main voltage (Vcc a.k.a. Vcore), one for the CPU VSA voltage (memory controller), and one for the CPU VTT voltage (PCI Express and DMI interfaces). Therefore, it uses a “4+1+1” configuration, which is incorrectly advertised by the manufacturer as “4+2.” The voltage regulator is controlled by an L6718 integrated circuit, using a digital design, which is superior to the hybrid design usually seen on motherboards from ASRock.

The ASRock Z77 Extreme4-M uses solid electrolytic capacitors and ferrite coils.
