ASUS Crosshair V Formula Motherboard

Voltage Regulator

The CPU voltage regulator circuit of the Crosshair V Formula has eight phases for the CPU main voltage (VDD a.k.a. Vcore) and two for the CPU VDDNB voltage (integrated memory controller, HyperTransport bus controller, and L3 memory cache). Therefore, it uses an “8+2” configuration.

This motherboard uses solid ferrite-core coils, which present less energy loss than iron-core coils (i.e., they improve efficiency), and solid capacitors, using a digital design.
