2.5.25 DRAM Voltage [Auto]
Allows you to set the DRAM Voltage. You can use the <+> or <‑> keys to adjust the value.
The values range from 1.1850V to 1.8000V with a 0.0050V interval.
According to Intel CPU specifications, DIMMs with voltage requirement over 1.65V may
damage the CPU permanently. We recommend that you install the DIMMs with the voltage
requirement below 1.65V.
2.5.26 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 1.1850V to 2.1350V with
a 0.0050V interval.
2.5.27 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.
2.5.28 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 0.39500V to
0.63000V with a 0.00500V interval.
2.5.29 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 0.39500V to
0.63000V with a 0.00500V 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.
2.5.30 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]
