ECS H67H2-M Motherboard

Voltage Regulator

The ECS H67H2-M comes with a six-phase voltage regulator circuit. Of the six available phases, four are used to generate the CPU main voltage (Vcc, a.k.a. Vcore), one is used to generate the voltage required by the integrated memory controller and the L3 memory cache (VTT), and one is used to generate the voltage required by the CPU integrated video controller (VAXG). Therefore, this motherboard has a “4+1+1” configuration.

The motherboard comes with two passive heatsinks on top of the voltage regulator transistors, connected to each other using two heatpipes.

All capacitors used on this motherboard are solid 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.
