Chapter 3
The following item appears only when you set SVID Support to
[Enabled]
.
SVID Voltage Override [Auto]
This item allows you to set the SVID Voltage override. By default, this item takes the
standard value of the installed CPU. You can use the <+> or <-> keys to adjust the
value. The values range from 0.001V to 2.440 V with a 0.001 V interval.
DRAM Voltage [Auto]
This item allows you to set the DRAM voltage. You can use the <+> or <-> keys to adjust the
value. The values range from 1.1850 V to 1.8000 V with a 0.0050 V interval.
According to Intel
®
CPU specifications, DIMMs with voltage requirement over 1.65 V may
damage the CPU permanently. We recommend that you install the DIMMs with the voltage
requirement below 1.65 V.
PCH VLX Voltage [Auto]
This item allows you to set the I/O voltage on the PCH (Platform Controller Hub). You can
use the <+> or <-> keys to adjust the value. The values range from 1.1850 V to 2.1350 V with
a 0.0050 V interval.
PCH Core Voltage [Auto]
This item allows you to set the core voltage on the PCH (Platform Controller Hub). You can
use the <+> or <-> keys to adjust the value. The values range from 0.73500V to 1.50000V
with a 0.00500V interval.
The system may need better cooling system for a more stable performance under high
voltage settings.
DRAM CTRL REF Voltage [Auto]
This item allows you to set the DRAM reference voltage on the control lines from the memory
bus. You can use the <+> or <-> keys to adjust the value. The values range from 0.39500x to
0.63000x with a 0.00500x interval.
To set a value for the DRAM reference voltage, we recommend you to set a value close to
the standard value which is 0.500000x.
DRAM DATA REF Voltage on CHA/CHB [Auto]
This item allows you to set the DRAM reference voltage on the data lines on Channels A and
B. You can use the <+> or <-> keys to adjust the value. The values range from 0.39500x to
0.63000x with a 0.00500x interval.
To set a value for the DRAM reference voltage, we recommend you to set a value close to
the standard value which is 0.500000x.
CPU Spread Spectrum [Auto]
This item allows you to enhance the BCLK overclocking capability or reduce the EMI
(electromagnetic disturbance) generated by the BCLK. Set this item to [Enabled] for EMI
reduction, or set this item to [Disabled] to enhance BCLK overclocking. Configuration options:
[Auto] [Disabled] [Enabled]
