ASRock 870iCafe Motherboard
Voltage Regulator
Contents
The ASRock 870iCafe comes with a five-phase voltage regulator circuit. From the five available phases, four are used to generate the CPU main voltage (VDD, a.k.a. Vcore), while the other one is used to generate the voltage required by the integrated memory controller, the HyperTransport controller, and the L3 memory cache (VDDNB). Therefore, this motherboard has a “4+1” configuration.

All capacitors used on this motherboard are solid made in Japan and the voltage regulator circuit uses ferrite chokes, which are better than iron chokes. Please read our Everything You Need to Know About the Motherboard Voltage Regulator tutorial for more information.
