CPU Internal PLL Voltage
Default is 0.900V. Each step is 0.015V. Adding 9- 15 steps will helps CPU PLL
to lock internal clock during High frequency under Ln2 cooling. For example:
1.020V -1.125V will be proper value. But the voltage level will be different on each
processor. User has to find the best value for your own processor. CPU Vcore
Voltage must higher than CPU Internal PLL Voltage, or your processor will hang.
CPU Core AC LoadLine
AC Loadline defined in 1/100 mOhms. A value of 100 = 1.00 mOhm. and 1255 =
12.55 mOhm. Range is 0-6249 (0-62.49 mOhms). 0 = AUTO/HW default. UsesBIOS
mailbox command 0x2.
CPU Core DC LoadLine
DC Loadline defined in 1/100 mOhms. A value of 100 = 1.00 mOhm. and 1255 =
12.55 mOhm. Range is 0-6249 (0-62.49 mOhms). 0 = AUTO/HW default. UsesBIOS
mailbox command 0x2.
