DRAM Frequency
Allows you to select the DRAM operating frequency or select [Auto] to apply the optimized
setting. Conguration options: [Auto] [DDR4-784MHz] – [DDR4-45907MHz]
The conguration options vary with the BCLK Frequency setting.
Selecting a very high memory frequency may cause the system to become unstable! If this
happens, revert to the default setting.
OC Tuner
Allows you to select the mode of OC Tuner. OC Tuner automatically overlocks the CPU or
DRAM frequencies and voltage for an enhanced system performance depending on the
DRAM type and an accelerated iGPU performance depending on the iGPU loading. Install an
effecient CPU fan for OC Tunder I or Tunder II mode selection.
Conguration options: [Keep Current Settings] [OC Tunner I] [OC Tuner II]
DRAM Timing Control
The sub-items in this menu allow you to set the DRAM timing control features. Use the <+>

Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
