Additional Processor Information
CPU Power Voltage Regulation Modules (EVRD 11.1): Voltage regulation to the G34
processor is provided by EVRD (Enterprise Voltage Regulator-Down). EVRDs are
embedded on the planar. CPU core voltage is not shared between processors. EVRDs
support dynamic phase shedding, controlled by the CPUs in response to CPU utilization
and power state. The core regulators will operate with 4 phases normally; and drop to
two phases when the CPU indicates lower power requirement.
