DRAM Frequency
Allows you to select the DRAM operating frequency or select [Auto] to apply the optimized
setting. Configuration options: [Auto] [DDR4-784MHz] – [DDR4-45907MHz]
The configuration 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
