Chapter 4: BIOS setup
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.50V to 3.10V with a
0.02V interval.
NB Voltage [Auto]
Allows you to set the North Bridge voltage. The values range from 1.30V to 2.00V
with a 0.02V interval.
• Setting the
FSB Termination Voltage
,
DRAM Voltage
and
NB Voltage
items to a high level may damage the chipset, memory module and CPU
permanently. Proceed with caution.
• Some values of the
FSB Termination Voltage
,
DRAM Voltage
and
NB
Voltage
items are labeled in different color, indicating the risk levels of high
voltage settings. Refer to the table below for details.
• The system may need better cooling system to work stably under high
voltage settings.
