ASRock Z77 Extreme11 Motherboard
Voltage Regulator
Contents
The CPU voltage regulator circuit of the ASRock Z77 Extreme11 has eight phases for the CPU main voltage (Vcc a.k.a. Vcore), two for the CPU VSA voltage (memory controller), and two for the CPU VTT voltage (PCI Express and DMI interfaces). Therefore, it uses an “8+2+2” configuration, which is incorrectly advertised by the manufacturer as “8+4.” The voltage regulator is controlled by an ISL6367 integrated circuit, using a hybrid design.

The ASRock Z77 Extreme11 uses solid capacitors and ferrit
e-core coils.
