Clock/Voltage Generation and Distribution

Intel® Server Board SDS2

7.2Voltage

The system power supply provides +3.3V, +5V, +12V, -12V, and +5VSB and voltage regulators on the Server Board are used to create the following voltages:

∙+3.3VSB

∙VCORE for the CPUs

∙VTT for the CPUs

∙+2.5V for the chipsets

∙+1.8V for the onboard SCSI

The following figure illustrates voltage generation and distribution on the SDS2 Server Board.
