DRAM Current Capability
This item provides a total power range for DRAM overclocking. A higher value setting
provides higher power consumption delivery and extends the overclocking frequency
range simultaneously. Conguration options: [100%] [110%] [120%] [130%] [140%]
Congure higher values when overclocking or under a high CPU loading for extra power
support.
DRAM Power Phase Control
This item allows you to set the power phase control of the DRAM. Conguration
options: [Optimized] [Extreme]
DRAM Switching Frequency
This item affects the VRM transient response speed and the component thermal
production. Select [Manual] to congure a higher frequency for a quicker transient
response speed. Conguration options: [Auto] [Manual]
DO NOT remove the thermal module. The thermal conditions should be monitored.
The following item appears only when you set the DRAM Switching Frequency to
[Manual].
Fixed DRAM Switching Frequency(KHz)
This item allows you to set a higher frequency for a quicker transient
response speed. Use the <+> or <-> to adjust the value. The values range
from 300 KHz to 500 KHz with an interval of 50 KHz.
Do not remove the thermal module when the manual mode is selected. The thermal
conditions should be monitored.
DRAM VBoot Voltage
This item allows you to set the Boot up voltage for the DRAM. Use the <+> and <->
keys to adjust the value. To restore the default setting, type [auto] using the keyboard
and press the <Enter> key.

VTTDDR AB Voltage
Conguration options: [Auto] [0.50000] - [1.30000]
VTTDDR CD Voltage
Conguration options: [Auto] [0.50000] - [1.30000]
DRAM CTRL REF Voltage on CHA/ CHB/ CHC/ CHD
Congures the DRAM reference voltage on the control lines. The reference voltage
will be the DRAM voltage times the congured value. Conguration options: [Auto]
[0.39500] - [0.63000]
VPP DRAM AB
Conguration options: [Auto] [2.50000] - [3.13500]
