Introduction
• Intel® Virtualization Technology (Intel® VT) – Processor virtualization which
when used in conjunction with Virtual Machine Monitor software enables multiple,
robust independent software environments inside a single platform.
• VRM (Voltage Regulator Module) – DC-DC converter built onto a module that
interfaces with a card edge socket and supplies the correct voltage and current to
the processor based on the logic state of the processor VID bits.
• EVRD (Enterprise Voltage Regulator Down) – DC-DC converter integrated onto
the system board that provides the correct voltage and current to the processor
based on the logic state of the processor VID bits.
• V
CC
– The processor core power supply.
• V
SS
– The processor ground.
• V
TT
– FSB termination voltage. (Note: In some Intel processor EMTS documents,
V
TT
is instead called V
CCP
.)
