Gigabyte 880GMA-UD2H Motherboard

Volt age Regulator

The Gigabyte 880GMA-UD2H comes with a five-phase voltage regulator circuit. Of 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.

In Figure 9, you can see the voltage regulator circuit.

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.
