ECS P67H2-A Motherboard
Voltage Regulator
Contents
The ECS P67H2-A comes with a 13-phase voltage regulator circuit, which is an impressive improvement for ECS. Of the 13 available phases, 12 are used to generate the CPU main voltage (Vcc, a.k.a. Vcore), while the other one is used to generate the voltage required by the integrated memory controller, the QPI controller, and the L3 memory cache (VTT). Therefore, this motherboard has a “12+1” configuration.
The motherboard comes with passive heatsinks on top of the voltage regulator transistors, connected to the passive heatsink used on top of the Lucid HydraLogix 200 processor using heatpipes.

The P67H2-A comes with a series of 12 LEDs to indicate which phases of the voltage regulator circuit are being used at the moment.

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.
