Intel D845GVSR,

Doesn't have a Voltage Regulator Module.

It has a motherboard voltage regulator circuit. It is integrated into the motherboard, not a separate module.

You will have to find the components, in the motherboard voltage regulator circuit, yourself.

How?

Electrolytic Capacitors are the weakest link in the motherboard voltage regulator circuit.

Part of what the motherboard voltage regulator circuit does, is to regulate voltage for the Processor.
Just like a VRM does.

A Processor has to have a steady, 'clean', supply of voltage, and it MUST be within a VERY small tolerance range.
Cannot be too much, or too little.
