ASRock X79 Extreme6/GB Motherboard

Voltage Regulator

The CPU voltage regulator circuit of the ASRock X79 Extreme6/GB has 12 phases for the CPU main voltage (Vcc a.k.a. Vcore), two for the CPU VSA voltage (memory controller), and one for the CPU VTT voltage (PCI Express and DMI interfaces). Therefore, it uses a “12+2+1” configuration. The voltage regulator is controlled by a CHiL CHL8328 integrated circuit, using a digital design.< /p>

The ASRock X79 Extreme6/GB uses SMD (a.k.a. highly-conductive polymerized or simply Hi-c) electrolytic capacitors in its main voltage regulator circuit. All coils on this motherboard are ferrite-core models, which can provide up to 20% improvement in efficiency. The rest of the electrolytic capacitors used on this motherboard are solid, manufactured in Japan.
