CPU VCore up to 1.7v:
CPU PLL voltage up to 2.78v:
FSB Voltage up to 1.5v:
DDR3 Memory Voltage up to 2.78v, like CPU PLL. Perhaps it is generated from the exact same regulator.
Northbridge voltage up to 1.91v:
Southbridge voltage up to 1.2v:
Clock overcharging voltage, maybe something to do with the clock generator:
CPU Voltage Damper to adjust voltage droop according to load:
CPU GTL Reference voltage derived from FSB voltage:
At default voltage, the Intel X38 chipset only runs slightly warm without a fan on it.
