Chapter 3: BIOS setup
DRAM Voltage (CHA, CHB) [Auto]
Allows you to set the DRAM voltage. The values range from 1.20V to 1.99V with a 0.005V
interval.
DRAM Voltage (CHC, CHD) [Auto]
Allows you to set the DRAM voltage. The values range from 1.20V to 1.99V with a 0.005V
interval.
According to Intel CPU spec, DIMMs with voltage requirement over 1.65V may damage
the CPU permanently. We recommend you install the DIMMs with the voltage requirement
below 1.65V.
CPU PLL Voltage [Auto]
Allows you to set the CPU and PCH PLL voltage. The values range from 1.80V to 2.10V with
a 0.00625V interval.
VTTCPU Voltage [Auto]
Allows you to set the VTTCPU voltage. The values range from 1.05V to 1.70V with a
0.00625V interval.
PCH 1.1v Voltage [Auto]
Allows you to set the 1.1v Platform Controller Hub voltage. The values range from 1.10V to
1.70V with a 0.00625V interval.
PCH 1.5v Voltage [Auto]
Allows you to set the 1.5v Platform Controller Hub voltage. The values range from 1.50V to
1.80V with a 0.00625V interval.
•
The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage,
VCCSA Voltage, VCCIO Voltage, CPU PLL Voltage, and PCH 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.
VTTDDR Voltage (CHA, CHB) [Auto]
Allows you to set the active termination voltage for DRAM on Channel A and B. The values
range from 0.6250V to 1.10V with a 0.00625V interval.
VTTDDR Voltage (CHC, CHD) [Auto]
Allows you to set the active termination voltage for DRAM on Channel C and D. The values
range from 0.6250V to 1.10V with a 0.00625V interval.
DRAM CTRL REF Voltage on CHA [Auto]
Allows you to set the DRAM CTRL REF Voltage on Channel A. The values range from
0.3950V to 0.6300V with a 0.005V interval.
DRAM DATA REF Voltage on CHA [Auto]
Allows you to set the DRAM DATA REF Voltage on Channel A. The values range from
0.3950x to 0.6300x with a 0.005x interval.
