Super I/O

The motherboard features a LPC47M10x Super I/O controller chip which manages all the I/O [3] ports through the LPC bus

VRM

The motherboard features a double EVRD 11.0 (VRM [4]).

The common term nowadays is VRM but when this motherboard first came out, Intel designated its voltage regulator circuit as an Enterprise Voltage Regulator-Down.

The only difference is that the EVRD is compliant to all the CPUs power specifications by Intel that are compatible with the motherboard, which means its more enterprise and high-end suitable

Gigabyte called it DPS and it was an add-in pluggable module that provided some Pentium 4 CPUs with 4 extra power phases to reach higher overclock.

Having a look at the VRM, it can be said its design is a 4+1 power phases without doublers. Each CPU has its own VRM module and also PWM [5] chip

Most high-end motherboards come with passive or active cooled heatspreeders for the VRM MOSFETs since they get pretty hot and are responsible of providing and filtering the power to the CPU.
Some of them are even water cooled
