DRAM Training [Auto]
This item allows your system to set DRAM training test function.
DRAM SPD Write
This item is for advanced DRAM programming only. It allows you to enable DRAM
SPD write to enable memory SMBus programming.
External Digi+ Power Control
CPU Input Boot Voltage [Auto]
This item allows you to set a higher CPU input boot voltage for better overclocking
capability. Use the <+> or <-> to adjust the value. The values range from 0.80 V to 2.7
V with an interval of 10 V.
CPU Load-line Calibration [Auto]
Load-line is defined by Intel ® specification and affects CPU power voltage. The CPU
working voltage decreases proportionally to CPU loading. Higher load-line calibration
could get higher voltage and good overclocking performance, but increases the CPU
and VRM thermal conditions. Select from levels 1 to 9 to adjust the CPU power voltage
from 0% to 125%.
Configuration options [Auto] [Level 1] - [Level 9]
The actual performance boost may vary depending on your CPU specification.
DO NOT remove the thermal module. The thermal conditions should be monitored.
CPU VRM Switching Frequency [Auto]
This item affects the VRM transient response speed and the component thermal
production. Select [Manual] to configure a higher frequency for a quicker transient
response speed.
Configuration options: [Auto] [Manual]
DO NOT remove the thermal module. The thermal conditions should be monitored.
The following item appears only when you set the CPU VRM Switching Frequency to
[Manual] .
Fixed CPU VRM Switching Frequency (KHz) [300]
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.
