8.1Power Generartion
Input power to the Mainboard is 12V and 3.3Vstby; all other required voltages are generated by Voltage Regulator Down (VRD) circuits and Voltage Regulator Modules (VRMs) on the Mainboard. The processor core voltages for processor sockets 1 and 2 are generated by VRDs and processors 3 and 4 get their core voltage from VRMs. One VRD generates the cache voltage for processors 1 and 2, and a VRM 9.1 provides cache voltage for processors 3 and 4, when those sockets are used by
