Which of the following describes how many VRM's would be required in a system with quad Xeon CPU's?

A single VRM cannot provide independent voltage regulation for four separate CPUs, as each processor typically has unique power requirements.

Two VRMs are insufficient for a quad-CPU system, as each CPU requires its own dedicated power regulation for optimal stability and performance.

Three VRMs would leave one CPU without its necessary voltage regulation, leading to system instability or failure in a quad-CPU configuration.

A VRM (Voltage Regulator Module) is responsible for supplying the correct and stable operating voltage to a CPU. In a system equipped with four separate Xeon CPUs, each CPU requires its own dedicated VRM or power delivery phase to ensure proper power regulation and stable operation, thus requiring four VRMs.
