********

System Voltage Optimized

********

System Voltage Control

Determines whether to manually set the system voltages.

Auto

lets the BIOS automatically set the

system voltages as required.

Manual

allows all voltage control items below to be conﬁgurable. (Default:

Auto)

CPU PLL Voltage Control

Allows you to set the CPU PLL voltage.

Normal

Supplies the CPU PLL voltage as required. (Default)

2.220V ~ 3.100V

The adjustable range is from 2.220V to 3.100V.

Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU.

DRAM Voltage Control

Allows you to set memory voltage.

Normal

Supplies the memory voltage as required. (Default)

1.350V ~ 2.400V

The adjustable range is from 1.350V to 2.400V.

Note: Increasing memory voltage may result in damage to the memory or reduce the useful life of the

memory.

Bank Interleaving

Enables or disables memory bank interleaving.

Enabled

allows the system to simultaneously access dif-

ferent banks of the memory to increase memory performance and stability. (Default: Enabled)

Channel interleave

Enables or disables memory channel interleaving.

Enabled

allows the system to simultaneously access

different channels of the memory to increase memory performance and stability. (Default: Enabled)
